2. Do Now: Answer the following question
What are the 3 types of scientific investigations?
Observational Studies
Comparative Studies
Controlled Experiments
What is one possible research question for each investigation?
Observational Studies: “How tall is the average human?
Comparative Studies: “On average, are males taller than females?
Controlled Experiments: “Does calcium consumption have an affect on how tall animals grow?”

3. Assignment Review: Identifying Parts of an Experiment
How Dependent Variable is Measured:
Independent Variable:
pH of water solution
Record how many days it took for the beans to sprout
Control Group:
Constants
pH 7
Size of cups
Experimental Groups:
Amount of soil
pH 3, pH 9
Number of beans in each cup
Dependent Variable:
Same amount of water solution
Germination rate
Same window sill

4. Group Work: Meet the Scientist
Lesson Objective: Students will be able to give examples of how scientists can gain scientific knowledge without experimentation
Groups will be assigned a scientist to read about.
After you read about the different scientists, answer questions about them in the “Meet a Scientist” worksheet.
Then each group will share with the class a summary of their scientist's work and the methods they use in solving problems. You can do this by creating a drawing or acting it out.
