Do now:
Answer the following question in your notebook
What are the six skills scientists use?
Observing
Classifying
Making models
Inferring
Predicting
Analyzing
In your class notes, title the page, BASKET ACTIVITY

2. Chapter 1, lesson 1-How scientists work
What skills did we demonstrate with the items in the colored basket?
Academic Language
Classifying-grouping together items that are similar in some way
Observing- using one or more of your senses to gather info
Quantitative- numbers or amounts
Qualitative-a description

3. Chapter 1, lesson 1-How scientists work
Look at the picture below. On a sheet of notebook paper, write down as many observations as possible

4. Chapter 1, section 1- How scientists work
Using the same picture, on the same paper, write down as many inferences as you can

5. Chapter 1, section 1- How scientists work
Using the same picture, on the same paper, predict moms reaction when she walks into the room

6. Chapter 1, section 1- How scientists work
Academic Language
Inferring-explaining or interpreting things you have observed, can be thought of as a “why”
Inferences are based on prior knowledge and observations
Ex. Why is the dog dirty and wet?
Predicting-a statement or about what will happen in the future based on past experience or evidence
Ex. What will moms reaction be?
Analyzing-evaluating observations and data to reach a conclusion about them
Making a model
Why make models?
-it’s a way to represent complex object or process that we cannot easily observe

7. Chapter 1, section 1- How scientists work
Based on the skills we have learned that scientists use…how can we define the word science?
Academic Language
Science-
a way of learning about the natural world
includes the knowledge we gain through exploration

8. Characteristics of Scientific Knowledge and designing an experiment
What is the catalyst for a scientific investigation?
Skepticism-doubt, un acceptance of ideas (p.11)
Scenario: My favorite snack is microwave popcorn. I hate the fact that when I poor it into the bowl, there are so many un- popped kernels. Lets come up with a test, using the scientific method.
1.) Question/Problem/Purpose-what are you trying to find out, why are you trying to answer this question?
2.) Research-find out about the topic/problem
3.) Hypothesis- A prediction, explanation or possible answer to scientific question; includes independent variable and dependent variable when written, MUST be testable

9. Characteristics of Scientific Knowledge and designing an experiment
4.) Experiment-the test/procedure to test the hypothesis, includes the materials and procedure and data Controlled experiment-an experiment where only one variable is changed at a time Data-facts figures and other evidence collected during investigation (p.12) a.) Control Group- “normal” group, the independent variable is NOT included b.) Experimental Group-group that includes “the change”, the group includes the independent variable Variables: a.) independent- the thing that you change b.) dependent- the thing that you measure, it changes because of the independent variable c.) constant variables-the things that are the same in each group Repeated Trials- repetition of experiment—THIS IS A MUST Replication-attempt to repeat a scientists experiment by a different scientist or group of scientists **You procedure must be written clearly to allow for replication and to avoid bias Bias-error in the design of the experiment that affects the results

10. Characteristics of Scientific Knowledge and designing an experiment
5.) Analysis-determining what your data means, this is where you include graphs, use those math skills that are covered in chapter 2 ***Make sure to use objective reasoning, not subjective reasoning Objective Reasoning-based on evidence Subjective reasoning- based on personal feelings or values, an opinion 6.) Conclusion- Does your data support your hypothesis **what is another question you now have-a good investigation should ALWAYS lead to further questions Drawing a conclusion is a way to develop a scientific explanation Scientific explanation-generalization that makes sense of observations by using logical reasoning
