8. 3. What is the Scientific Method?
Definition: The system of steps that scientists use to try and solve a problem

9. 4. Scientific Method Steps
Step #1: Question Step #2: Hypothesis Step #3: Experiment Step #4: Collect Data Step #5: Conclusion Step #6: Communication

10. 5. What step of the scientific method is where you share the results with others?
Communication

11. 6. Observations
Direct: Looking at with your eyes and being able to touch something or use your senses.
Indirect: Not observing the organism, but instead something that is left behind.

12. 7. What is a direct observation about the picture below?
It has tires
It is yellow
It as 3 windows
What if this was not a
colored picture?

13. 8. Controlled Experiment
Everything is the same
Only ONE thing is tested or changed!!!! (Variable)

14. 8. Why is it important to have
A controlled experiment?
CONSISTENCY!

15. 9. How many times do you complete an experiment?
Multiple Times!
The more times you complete the experiment, the more evidence you have

16. 10 & 11. Parts of an experiment
Group Control: Group not getting the independent variable
Independent Variable: One thing that you are changing or testing
Dependent Variable: Effect of the independent variable

17. 12. Control Group? Group A Group B Water + Fertilizer
Water + No Fertilizer
Group A
Group B

18. 12. Independent Variable? Group A Group B Water + Fertilizer
Water + No Fertilizer
Group A
Group B

19. 12. Dependent Variable? Group A Group B Water + Fertilizer
Water + No Fertilizer
Group A
Group B

20. 13. Spontaneous Generation
The mistaken idea that living things were able to come from non-living things
We now know this is no longer true
Redi’s experiment!

21. 14. Spontaneous Generation
Redi’s Experiment
Trying to disprove flies coming from meat
Control Group: Jar without cover
Independent Variable: Cover
Dependent Variable: Flies

22. 15. What’s the difference between an inference and an Observation?
Inference is about the past or what is happening now
Observation is using your senses to gather information

23. 15. Inference vs Observation

24. 16. Creating Predictions About the future!
I think that the bears will win the game on Sunday.

25. Growth Metabolism Response
Characteristic
Definition
Example
Growth
All living things grow and develop over time
A tadpole turns into a frog
Reproduction
Ability of organism to make more of itself
Flies must produce other flies
Metabolism
All the chemical reactions that take place in an organism
Use Sunlight
to get energy
Response
Respond to changes in the environment
Plant growing towards sunlight

26. Shoes and appropriate clothing
18. Lab safety
Good things:
Hair tied up
Lab goggles
Lab jacket
Shoes and appropriate clothing

27. 18. Lab safety Bad things: Outlet Both not wearing goggles
Chemicals spilled and not picked up
Beakers set on the ground

28. 19. Math practice
Mean (Average): Add all the numbers and divide by the number of integers added
Mode: Most common number
Median: Put all the numbers in order and it’s the middle number

29. Graph Practice
20. Water temperature is related to heating time by the longer it heats, the higher the temperature (increase together)
21. You need to heat water 3 minutes to get to 80 degrees Celsius
22. I would predict that after 6 minutes, the water would have heated to 110 degrees Celsius

30. Graph Practice Number of Insects
23. Insect 2’s population is double that of insect 4
24.Smallest population is Insect 6 and greatest is Insect 1
If this image
Was on the test
It would be in
COLOR!
Number of Insects

31. 25. 7 Am – 1 pm?
Increase in wind speed

32. 26. Decrease from 1pm to 5 pm?
25 mph – 10 mph = 15 mph

33. 27. Time that winds were 20 mph?
11 am

34. 28. Wind Speed at 3 pm?
15 mph

35. 29. Average
= mph

36. 30. MEdian
5 , 10 , 10 , 15 , 20 , 25
= 25 / 2 = 12.5
