Transcript: What does it cost Americans in Dollars? We use 100 percent of our brain. Three forms of evidence for concluding that the mind is the brain in action 1. Brain activity changes with different behaviors and perceptions 2. Brain damage causes deficits in behavior and perception 3. Stimulation of the brain activates behavior and/or perceptions If you learn something new and do it only once or twice, the dendrite connection is very fragile and can disappear within hours. Within 20 minutes, you remember only 60%. Within 24 hours, you remember only 30%. But if you practice within 24 hours, and then practice again later, you remember 80%. The World Health Organization has reported that 4 of the 10 leading causes of disability in the US and other developed countries are mental disorders. By 2020, Major Depressive illness will be the leading cause of disability in the world for women and children. Five Leading Causes of Deaths Among Persons Ages 15–19 Years, United States, 2010 (CDC 2010) Biological Psychology With enough practice, the dendrites build a double connection. Faster, stronger, double connections last a very long time. You remember what you learned! You must do something active to learn, because… The Autonomic Nervous System The Brain and Emotion: Limbic Circuits Make he Most of Practice Time… The Forebrain (forward-most) Leading Causes of Death... Dendrites grow ONLY when you are actively doing something. No one else can grow dendrites for you! Regions of the Brain Learning is Biological and Natural! What is Depression: What Causes Depression? The Forebrain Short-Term Memory is VERY Short! The More You the Faster the Connections Dendrites Take Time to Grow Learning... The Endocrine System: Hormonal Regulation The Forebrain The Forebrain You grow dendrites for exactly the same thing you are practicing. If you listen or watch psychology issues and concerns are being discussed, you grow dendrites for listening or for watching. If you actually address and solve the concerns yourself, you grow dendrites for solving. Basal Ganglia Control of voluntary movement (with help of motor cortex) Reward-related movement The Use of Drugs and Alcohol can impact the Basal Ganglia… Topic 6 The More You Practice the Stonger the Conncetions Mapping Our Brains Five Leading Causes of Deaths Among Persons Ages 20–24 Years, United States, 2010 Dendrites Cannot Grow in a Void. Thalamus Sensory gateway to the cerebral cortex. Its function includes relaying sensation, special sense and motor signals to the cerebral cortex, along with the regulation of consciousness, sleep and alertness Hypothalamus maintains internal bodily states by overseeing the endocrine and autonomic nervous systems (e.g., releases hormones to influence hunger, sexual motivation) Special chemicals called neurotransmitters carry the electrical signals across the synapse. When you practice something, it gets easier for the signals to cross the synapse. That’s because the contact area becomes wider and more neuro- transmitters are stored there. The Brain and Emotion: Limbic Circuits Biological Psychology is the study of the brain and behavior Our brains contains approximately 100 billion neurons (nerve cells), *and maybe even billions more! Topic 7 Practicing Builds Double Connections. When you practice something, the dendrites grow thicker with a fatty coating of myelin. The thicker the dendrites, the faster the signals travel. The myelin coating also reduces interference. Occipital Lobe - vision Visual cortex Sensory Cortical Hierarchies Association Cortex (e.g., conscious perception of visual scene Sensory cortex (e.g., visual ctx) Sensory info (e.g., light) Pituitary gland "The Master Gland” Controls other bodily glands and is under control of the hypothalamus Adrenal glands release adrenaline and cortisol during physical and psychological stress activated by the sympathetic nervous system Sexual reproductive glands Testes produce testosterone Ovaries produce estrogen However, both sexes release some sex hormone associated with the opposite sex Amygdala Excitement, arousal, fear, social signals related to emotion, etc. Cingulate Cortex Active during emotional expression knowledge of socially appropriate behavior regulates autonomic nervous system Hippocampus spatial memory, fear conditioning, navigation, Injury: problem forming new memories It takes a lot of practice for dendrites to grow. This is why you do homework. This is why cramming doesn’t work. Making mistakes, and getting feedback allows you to check the accuracy of the connections in your brain. Be sure to get feedback quickly so you don’t practice the wrong thing and build a strong, but wrong, connection! Parietal Lobe perception of space, object shape and orientation, actions of others, numbers Integrates vision, touch, motor information Somatosensory cortex pressure, temperature, pain Brain cells are called neurons. You are born with at least 100 billion neurons. Dendrites (fibers) grow out of the

Transcript: Is this any better? discussion How does changing the conditions affects the growth of mould on bread? What does this all mean? What do we already know about biological science? What do we want to find out? How do I want to present and be graded on the work I produce? Task: Create a digital report on the growth of mould on your three types of bread over the past 2 weeks. who creating mould? can mould spread? why did scienctists create mould? what can mould do to you? how can we make more mould grow on bread? how does mould grow? when was mould discovered? how does mould spread? what is mould? how long does it take for mould to grow? what is it made of? why did we use sugar,lemon,water to grow mould? when/where was it made? what types of bacteria are in mould? Garry what can you use to make mould? why are different mould colonies differnt colours? Nathan was mould discovered or created? is it dangerous? what would happen if you ate mould? why are there chemicals in the mould? has eating mould lead to death? what things can mould grow on? Title: Growing Bread Mould Purpose: To investigate how changing the conditions affects the growth of mould on bread. Hypothesis: Make a prediction on what you think will happen to each piece of bread. Experiment Time Fungi are a group of living organisms which are classified in their own kingdom. This means they are not animals, plants, or bacteria. Unlike bacteria, which have simple prokaryotic cells, fungi have complex eukaryotic cells like animals and plants. Fungi are found throughout the Earth including on land, in the water, in the air, and even in plants and animals. They vary widely in size from microscopically small to the largest organisms on Earth at several square miles large. There are more than 100,000 different identified species of fungi. Hypothesis Why is there a green colour on the bread? how does it grow? why did it grow? why are there different colours? does it only grow on bread? do people eat mould? does it make you sick? is it harmful? is it germs? how does it feel? is the bread yucky? how can we keep it away? where does it come from? is it smelly? LH and B8 - Yr6s Question storming Mould Question storm in your groups Biological Science Extreme conditions in Antarctica Prior Knowledge Activity Equipment; 3 slices of bread (white, grain, wholemeal) lemon juice sugar 3 zip lock bags water sticky tape permanent marker Needs to include: -hypothesis (predictions) - what materials you used -how did you keep it to be a fair test -pictures - observations on the growth over time (measure the size it covered of the bread) - your own definition of mould -why is mould important to us? From last week and before we look at your bread experiment... Prediction: What do you think will happen to each piece of bread? Why? Discuss and record on your laptops with your groups that you worked with last week... How long will it take to produce mould? What variables did you keep the same and what was different? what steps did you take to make sure your test was a fair one? why do we need to make the experiment a fair test? Prompt: Picture Cards A fungus that produces a superficial growth on various kinds of damp or decaying organic matter B6 Question storming Question Storming What you will need

Transcript: The population - the individuals of a particular species within a given area. A population in nature will be defined within some kind of physiographic region such as a mountain range or contiguous habitat, and not by political boundaries. Ecologists study the distribution and abundance of populations within their habitats. Individual populations adapt to the particular characteristics of their habitat and thus differ from one another. Preservation of each population is important in preserving the gene pool of successful characteristics for the continued adaptation and evolution of earth's biota. Data about population fluctuations alone does not shed light on the causes of these fluctuations. Contents Professor Vicente CHEMISTRY PHYSIOLOGY Hannah Camaña Science And Its Impact to Society Topic 1: Science And Its impact on Society (Hannah Camaña) Topic 2: Scope And Meaning of Ecology (Ryzza Cabia-an) Topic 3: History aspects of Ecology (Kamille Borigas) Topic 4: Ecology: Its Relevance and Relationship to the other fields. (John Manuel Alejo) Topic 5: Laws of Ecology: Aplication to human society. (Elvira Beriña) The Four Laws of Ecology Formulated by physicist and ecologist, Barry Commoner. 1) Everything is connected to everything else - humans and other species are connected/dependant on a number of other species. 2) Everything must go somewhere - no matter what you do, and no matter what you use, it has to go somewhere. For example, when you burn wood, it doesn't disappear, it turns into smoke which rises into the air, and ash, which falls back down to the earth. 3) Nature knows best - Like it says, nature knows best. As much as you think it might help a place by repainting it, you are submitting the fumes into the air and into your lungs. Why not put siding on it? 4) There is no such thing as a free lunch - Everything you do, must have a reson behind it. For example, a class pizza party. In order to win the party, you have to fill out a survey, and submit it back to your teacher. This law basically means you have to do something in order to get something in return. References: Ecology is the study of earth's living systems and how they interact. It is not environmentalism, a social and political movement. Ecology is one of the most complex sciences and is very new. As such we are only at the beginning of our understanding of how environmental systems react and how a change in one element might affect a whole system or one organisms in that system. The community - consists of all the living organisms (the biota) in a given area and their interrelationships. Understanding the relationships between competitors, predators, prey, diseases, food supply etc. can shed light on the cause-effect relationships influencing population distribution and abundance. Ryzza Mae Cabia-an The species (or organism) - individuals identified by their common genetic makeup, behavior, physical characteristics and ability to breed with one another. Not all biologists agree on the definition of species. Ecologists study the above characteristics which have evolved to make the species successful in its habitat. Relation And Relevance of Ecology to Other Fields The ecosystem - both the biotic and abiotic components of a habitat and their interrelationships. Ecosystems form the working units of nature in which populations and communities work in balance with one another and with the non-living environment. But ecosystems are not homogeneous nor easily defined, and are therefore difficult to study scientifically. Ecology is a term coined from the Greek oikos, which means home, and the Latin and Greek roots of our word logic, which refers to scientific study or thought. Literally translated it is the study of the home. When first described in 1869 by Ernst Haeckel this new science dealt with the study of the relationships between an organism and its environment. Anthropology Kamille Borigas John Manuel Alejo Ecology is generally spoken of as a new science, having only become prominent in the second half of the 20th Century. More precisely, there is agreement that ecology emerged as a distinct discipline at the turn of the 20th Century, and that it gained public prominence in the 1960s, due to widespread concern for the state of the environment[1]. Nonetheless, ecological thinking at some level has been around for a long time, and the principles of ecology have developed gradually, closely intertwined with the development of other biological disciplines. Thus, one of the first ecologists may have been Aristotle or perhaps his student, Theophrastus, both of whom had interest in many species of animals. Theophrastus described interrelationships between animals and between animals and their environment as early as the 4th century BC (Ramalay, 1940). Here's a timeline of ecology as a science: Web of food late 1700's Antoine Lavoisier, a chemist, discovered Oxygen and Carbon and their importance to living things

Pick one living thing to describe and draw to Atto. Don't forget the living things features - looks like? Where does it live? What does it need to survive on earth? What is something special about your living thing? Why is it different from others? Plant Scan Scootle: Video prompt: Question storming Biological Science Book Prompt Page 4-7 Question Storming Dear miniature Earth beings, My name is Science Officer Atto and I am contacting you from my home planet Zeta Canis 1. I have been ordered by my superiors to visit your planet, Earth and study the living things found there. I must complete this mission successfully or I will be banished to the outer regions of my planet for many years. However, my new Earth friends, I must tell you that I am not a very good Science Officer. I do not know very much about your planet and I do not even understand the difference between living and non-living things. I have been too busy baking cupcakes in my lab to complete my scientific work, so this is my last chance to avoid being banished! I am asking all of you to be my new science partners and help me to complete my mission. All you need to do is to collect some samples and photograph them for me and give me some information on the living and non-living things on your planet. Any diagrams, information or videos would also be very helpful. I will be arriving on Earth soon and I have sent you a picture of myself so that you know what I look like, however you will not see me at all as I am able to create an invisibility field around myself and my ship. All I ask is that you collate your information and I will find a way to collect it and get it back to my planet safely. Thank you to all of you miniature Earth beings. I look forward to learning a lot from you all. -why did they go under the water an jump up? - what is it like inside the water - is it deep? -why does the dolphin have a tiny tale? - how did the whale get on and off of the white thing? - why did it do a back flip? -why do whales live in water? m -why is the whale is fat?

Great with students, workers, family, etc. For example: With games like Jeopardy and Family Feud, players can pick practically any answers. The person who is running the game will have to have all of the answers in order to determine if players are correct or not. However, with a game like Who Wants to be a Millionaire, the players only have a choice between answers, A, B, C, or D. Therefore, when the player decides their answer, the person running the game clicks it, and the game will tell them whether they are right or wrong.


Transcript: PLANTS VS. ANIMALS In the early 19th century, Jean Baptiste Lamarck proposed the theory of evolution. But the most outstanding contribution to evolution came from Charles Darwin who proposed the natural selection as an explanation by which evolutionary changes take place. Louis Pasteur ‘The Father of Modern Microbiology’ laid the foundation of modern microbiology. Claude Bernard and Johannes Muller established comparative physiology. Karl von Baer founded comparative embryology. Gregor Mendel made studies on genetics and Hugo de Vries formulated the mutation theory. During the 20th century, many of the ideas of the past centuries were consolidated the refined and new concepts have been added. In endocrinology, our knowledge of hormones was increased by the work of E.H. Starling. Ecology came into existence at the time of Ernst Haeckel who stated that an organism was the product of the interaction of its environment with hereditary factors. Ecology was put on a modern basis by the American Botanists H.E. Cowla and F.E. Clements and zoologist V.E. Selford. Today, the generalization that all organisms living in a given area are closely interdependent with each other and with the environment is unifying biological concept as that of evolution. Modern biology is an enormous subject that has many branches. Some of these branches or fields of specialization of biologists are the following: Molecular biology and biochemistry. Scientists in this field work at the chemical level aiming at DNA, proteins, and other molecules that are involved in biological processes. Genetics. Scientists who study genes and their involvement in inheritance and development are called Geneticists. Cell biology. The study of individual cells or groups of cells often by culturing them outside organisms. Cell biologists also investigate how cells interact with each other and their environment. Physiology. The branch of biology that studies how organs and systems function in an organism. Scientific method is the making of careful observation and experiments, and later using data obtained to formulate general principles. The scientific method begins with recognizing the problem. Usually, curiosity helps us recognize a problem. Second, the scientist gathers and organize the data regarding the problem. In this way, instead of discovering things already discovered, the scientist utilizes the work of preceding scientists This is how science progresses. Third, the scientist attempts to explain the phenomenon in a working hypothesis. The hypothesis is made even before an experiment is made. It is a prediction regarding the problem or a tentative solution to the problem. Fourth, he plans experiment to test the validity of the hypothesis. If the experiment supports the hypothesis, the scientist then can formulate a more definite theory to explain the observed facts. We humans, ourselves are living things. BRANCHES Living Things vs. Non - Living Things BIOLOGY HISTORY OF BIOLOGY BRANCHES OF BIOLOGY HISTORY OF BIOLOGY BIOLOGY -is the sciece of life. BIOLOGICAL SCIENCE BRANCHES OF BIOLOGY BIOLOGICAL SCIENCE What is BIOLOGY? What are living things? Catabolism is the destructive or breaking down phase. This involves the release of energy by breaking food substances through respiration. Life refers to the properties and conditions which distinguish a plant and animal from inorganic matter or dead organism. While we define dead as deprived of life. So life is what animals and plants have when they are not dead, and dead is what those same organisms are when they lack life. Movement. Living things can move by themselves while non-living things can move with the help of an external force. Growth and life cycle. Living things exhibit internal growth or intussusceptions while non-living things exhibit external growth or accretion. WHAT IS SCIENCE? The primitive period is characterized by uncritical accumulation of information, mainly derived from the practical necessities of obtaining food, materials for clothing and shelter, substances to cure ailments, and necessary information about the human body. During this period, the accumulation of knowledge was recorded, nor were the scientific method and its associated intellectual activities a part of the procedure in learning about life. HISTORY OF BIOLOGY OF Irritability. Living things react to changes in the environment. These act as stimuli that induce responses by the organism. The degree of response is often disproportionate to that of the stimulus and the organism is not permanently altered by the stimulus. In non-living things, there is a definite quantitative relationship between the intensity of the environmental change and the reaction produced as in the expansion of a metal by heat. Reproduction. This is defined as the ability of the organism to create another one of the same kind. Living things reproduce by using the materials within their bodies, a characteristic which non-living things do not have.

Transcript: Mutations Two, Not Always Better Then One Deoxyribonucleic Acid Two For The Price Of One Some mutations don't have any noticeable effect on an organism. Some really important changes, like DDT resistance in insects are sometimes caused by single mutations. A single mutation can also have strong negative effects for the organism. The mutations that cause the death of an organism are called lethals. Mutations to control genes can transform one body part into another. Scientists have studied flies carrying Hox mutations that sprout legs on their foreheads instead of antennae! If you can change antennae to legs on your face then butt face can now be a scientific probability. DNA is what makes us look the way we are and act the way we do. One small change and we could be no more then bacteria. DNA is the genetic makeup that creates every living organism. Question time!! A mutation is a change in DNA. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Tim and Moby Animal cloning has been around for years, but had little attention until the birth of the first clone in 1996, a sheep named Dolly. Since Dolly, several scientists have cloned other animals, including cows and mice. The recent success in cloning animals has sparked fierce debates among scientists, politicians and the general public about the use and morality of cloning plants, animals and possibly humans. By Allana, Kayla and Hayley (DNA) TMNT is possible? Permanent Makeup?! Clones are genetically identical individuals. Twins are naturally created clones. We're just going to skip the baby making part and uh... yeah. Mutations are essential to evolution. When a cell divides, it makes a copy of its DNA and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation. Biological Science Hox Mutation On Jan. 8, 2001, scientists announced the birth of the first clone of an endangered animal, a large wild ox from India. Cloning is the process of making a genetically identical organism through nonsexual means.
