Transcript: History of the Earth 4.6 bya 4.6 billion years ago A protosun was born out of a nebula due to mutual gravitational attraction. Image credit: California Academy of Sciences 4.54 bya 4.54 billion years ago Earth was formed; however, the conditions on earth were as far from inhabitable as possible. A few million years after, Theia collided with earth — initiating the formation of the moon.

Afterward, the temperature slowly declined. Image credit: Mark A.

There were only volcanic islands. Image credit: Richard Bizley 2.5 bya - 650 mya 2.5 bya - 650 mya The first supercontinent Kenorland began to form 2.5 bya. Followed by Rodinia 1.9 bya and Pangaea 650 mya. Volcano eruptions released CO2 into the atmosphere, which melted the glaciers of the "Snowball Earth."

Air was filled with ash and carbon dioxide and lava was flowing everywhere. Dinosaurs replaced the destroyed species and took over the planet. Image credit: 50 mya 50 million years ago As volcanic activity and bolide impact brought about the extinction of dinosaurs, the power over the planet was passed on to mammals who actively spread and evolved with all their might. Meanwhile, the length of the day was almost 24 hours.

They are most likely members of the genus Dryopithecus, which are very similar in appearance to modern African apes. from Early Man (1965) 1.4 mya - Present 1.4 mya - Present Homo erectus began to colonize Eurasia and learned how to use fire 790 thousand years ago. About 300 thousand years ago, Homo sapiens appeared and began to actively populate the entire planet. Our ancestors then range from bet. 100 to 300 thousand individuals. At present, the world's population is 7.9 billion people. Reconstructions by: John Gurche


Transcript: EARTHY Names: María Belén Gomez Mariana Rivera Grade: 4°I Teacher: Silvia Riffo Jara Introduction Pollution is one of the problems that affects our world every day, being vegetation, animals and ourselves the hardest affected. The waste in public places and the plastics thrown into the ocean increase more and more. Description of our invention Our invention is a grey flying saucer, it absorb the garbage like a vacuum cleaner. It is managed remotely and can be configured depending on the place that needs to be cleaned so that it can operate in the best possible way, it will work with renewable energies like the solar, hydraulics and wind. The trash will be classified by the robot in such a way that it can be recycled. The creation of this invention is directed mainly to the care of the environment, benefiting at the same time to the animals, the vegetation and the people. The invention will be handled by experienced people and serve to keep clean the streets, beaches, squares, sea, etc. It works with renewable energies It help clean up public spaces It works in a fast and efficient way. It recycle the trash it accumulates. It's safe and helps environmental. Advantages It cannot be handled by people who don't know its correct functioning. Just clean the sea near the coast. If we using renewable energies, it is considered a high investment cost Buying it is expensive Disadvantages Our invention will have a positive impact on the environment and people. Besides being effective it will guarantee the maintenance of the cleanliness of the streets, beaches, rivers and other public places protecting the animals and the plants of our planet To conclude... "Ecological cleaner"

Earthy Expression

Transcript: Earthy Expressions of Emotion: Original Landscape Designs Lesson Goals The Process Draw final design in sharpie on your water color paper Focus on how landscapes can be visual metaphors for identity and emotion Learning to identify will strengthen the students' senses of self Plan your design, with thoughtful use of line, color, value and unity Learn how to express ideas using metaphor What metaphors could these paintings represent? What do you notice about line, color, value or unity? Teacher's Show and Tell! & tips, tricks and things to remember Painting # 3 The Final Product Students won't get three chances Recommend starting with line Discuss line, color, value and unity Discuss representation (metaphor) and reflection of art work Mix colors choices on extra paper The Activity by Graham Gercken What do you think the artist is expressing about this place? How does this place make you feel? Prioritize the list, so that the focus and content are considerate Characteristics: Panoramic view, wide with vanishing end points -Open minded, inclusive Mountains -Great depth and many levels Green, strong Reflective, cool Warm, bright What are we making? What are we making it out of? How big will it be? How much time do we have? What is it supposed to look like? What elements and principles should it have? What is a metaphor? Can it be a real place? Does it have to be a real place? What landscape features describe aspects of ourselves? What you should look for water color paintings by David Drummund Painting # 2 "Is this about sunsets?" Use of the line, color, value and unity Keeping aspects that are liked and changing aspects that are not liked In Chinese art, landscape paintings and poetry are considered spiritual ways to connect with many theological philosophies, especially Daoism, which is centered around respect for nature and the nature of being. BIG IDEA: Practice water color techniques on extra paper Assessment: Everyone will write what they really want heard. Please be considerate. All comments will be read out loud anonymously. Inappropriate comments will not be read or will be censored. Statements should be either 6-7 sentences elaborating on the same thought or 2-3 sentences explaining 3 different thoughts. What's HAPPENING? Introduce activity Share examples Discuss Criteria Teacher's "show and tell" discuss process Tips and Tricks Woulds and Wouldn'ts Questions/Answers ACTIVITY TIME!!! Assessment :) Discuss reflections What you should know & tips HAVE FUN! Assess and Reflect Examples Learn how to express identity lesson by Calli Loskill BIG PICTURE: line: a mark that spans a distance between two points (or the path of a moving point), taking any form along the way. As an art element, line pertains to the use of various marks, outlines and implied lines in artwork and design, most often used to define shape in two-dimensional art work. color: reflected light, tones and hues unity: how well different parts of an artwork build on each other. Harmony, not the same as unity, is achieved by using similar elements throughout the work, giving an uncomplicated look to a piece of artwork or sculpture. value: the relative lightness or darkness of a color. It defines form and creates spatial illusions. Contrast of value separates objects in space, while gradation of value suggests mass and contour of a contiguous surface. metaphor:The representation of a person, place, thing, or idea by way of a visual image that suggests a particular association or point of similarity Sense of style, personality, character You will be able to describe the tone of the artwork and make an educated guess at its meaning What metaphors could these landscapes represent? What do you notice about line, color, value or unity? by Graham Gercken Teacher's Example Draw at least three rough drafts in pencil and then sharpie We will focus on line, color, unity and value Make a list of characteristics that describe a landscape and yourself Learn how to express ideas using the elements and principles of Art and Design Remember, done is BETTER than perfect by Julie Gilbert Pollard What do you notice about line, color, value or unity? Painting # 1 The general idea Exploration with water color Experimentation Doubt/Dislike Change Keep the end result in mind Water color your line design!
