Transcript of Scientific Process
What is science?
What is a scientist?
A person who...
....as a way to gain new knowledge!
The word science comes from the Latin "scientia," meaning knowledge
Science is the process of:
Did you draw something like this?
Observation and Inference
: act of using one or more of your senses to gather information (Smell, touch, taste, see, hear)
: logical explanation of an observation that is drawn from prior knowledge or experience
A possible explanation for an observation that can be tested by scientific investigations. Written If…then…because
any item, factor, or condition that can be controlled or changed
set of directions
conduct an investigation
identify what data will be collected
& easy to follow
needs to be repeatable by other scientists
Conclusion and Results
Is a summary of your experiment- Explain what you observed, learned, concluded
Topic sentence restating purpose of lab
Rewrite your hypothesis
explain if it was right or wrong and WHY
Explain what the data means
Explain if there were any issues or problems and how did you resolve them
Concluding statement that summarizes the lab findings
What is being tested
What we look for a change in
Factors kept the same
is a process for experimentation that is used to explore observations and answer questions.
Examples to review as a class
(Changes as a result)
explanation based on inference
1.The higher the temperature of the air in the oven, the faster a cake will bake.
2.Lemon trees receiving the most water produced the most lemons.
3.An investigation found that more potatoes were produced when the soil was fertilized than when it wasn't.
4.Students measured the temperature of the water at different depths in Lake centennial and found that the temperature varied.
5.The more lead in gasoline the more pollution produced
1st step in the scientific process!
usually about something that you observe or wonder about
Start with words like How, What, When, Who, Which, Why, or Where?
Theory questions (require extensive knowledge)
Verification question (basic data collecting)
Experimental questions (testable)
3 types of science questions
build on prior knowledge
leads to other good questions
Good Science Questions
A set of values, facts, or information used to calculate, analyze, or plan something
can be qualitative (words) or quantitative (numbers)
can be represented using a model
dependent variable on the y-axis and the independent variable on the x-axis
Paper Airplane Lab
Discovery ed video
1 airplane per group
Step 1. Throw airplane, count in cm how far it traveled 1m=100cm
Step 2. repeat 4 times, then calculate average
Step 3. Add tape to nose, repeat steps 1 and 2
Step 4. Answer questions on the back
1. Look at the
in the bag!
DO NOT SHOW OTHER STUDENTS !
your paper and write down
about the object (
writing what the object is)
3. Put the object
in the bag & bring it
up to the front
, keep your numbered paper, wait to switch papers....
4. Without touching the bag, make an inference about what the object is and what it does. Write it on your paper. What is the evidence from your
to support this
5. Go find the matching bag!
6. Open the bag, was your
was correct? Explain.
Good Morning 9/12/17
1.Fill out agenda if you did not fill it out yesterday
2. Hold onto your Dodge ball money until the END of the class
3. Take out your bellwork and start answering these questions:
1. Explain what you think a procedure is?
2. List an examples of procedures we have in our classroom (both CMS and Science)
Lets Talk About it....
How do you think the term procedure might be used different in the science than in school?
Discuss how rules, instructions, and procedures are similar and different
