1. Bellringer:
Please clear all materials off your desk except for a pencil and your IAN (spiral notebook)

2. Conclusion/Reflections:
Teamwork requires Respect
“The impossible is often the untried!”
Jim Goodwin
Together Everyone Achieves More Success
So How Do We Individually Strive for Success?

3. Scientific Observations
In the Scientific Method
Review: What are the steps of the scientific method?

4. The Scientific Method
The Scientific Method is a series of steps to follow that help answer a question or solve a problem
- There are 5 main steps
(sometimes 6 ;)

5. Step 1: Ask a Question- Define a Purpose
Scientists ask questions based on observations from their surroundings
What would be a scientific question we tested in Monday’s experiment?

6. Step 2: Research your info and then, form a Hypothesis
Take an educated guess about what you think the answer is to your question
How and what did we
research?

7. Step 3: Test your hypothesis (procedure)
Set up an experiment to test your question. This needs to include your detailed hypothesis with
3 different variables!

9. Step 4: Analyze Your Results
Look at your results and decide what they tell you about your question
DATA

12. Step 5: Form a Conclusion
Decide what the answer to your question is and ask:
Was my hypothesis right or wrong?
Do I need to do the experiment again to find out more?

14. Types of Variables There are 3 main types of variables:
Independent Variable: The variable that is changed by the scientist; the ‘I control’ variable
Dependent Variable: The variable that might change because of what the scientist changes – what is being measured
Control Variables: conditions that are kept the same during the experiments.

15. Remember! Your hypothesis can TELL you what your variables are!
Ex. If I drink Mountain Dew before bed, then I will not sleep very much.
IV: Drinking Mountain Dew
DV: the amount of sleep
Control Variables: same bed,
same person, same time of night…

16. Use this hypothesis to identify the variables:
Practice
Use this hypothesis to identify the variables:
Hypothesis: If I leave all the lights on all day, then my electric bill will be expensive.
IV: ______________________
DV: ______________________
Control Variables: ________________
______________________________

17. Hypothesis: If I do not manage my study skills, then my grades will begin to drop.
IV: ______________________
DV: ______________________
Control Variables: _______________
_____________________________

18. Now read the following experiment and identify the independent and dependent variables
Elizabeth wanted to test if temperature affected how fast milk goes bad and curdles. She left milk in a room temperature closet, a fridge, and a oven that was turned on low heat. She then measured how rotten the milk was after 10 days.
IV: ____________________________________
DV: ____________________________________
Hypothesis: ___________________________
Control Variables:___________________
_______________________________________

19. ____ Label the independent and dependent variables?
Graph Checklist:
Did You:
____ Label the independent and dependent variables?
____ Put all the values on your y-axis by 10’s?
____ Put all your values by 10’s on your x-axis?
____ Give your graph a name?
