Study Guide Science Assessment #1 Test is Tuesday, November 6, 2012! Study Session is Tuesday morning at 7:15 am

Gram Balance 1. Metric System A. What is the basic unit of mass? What do you use to measure it? Gram Balance

Meter Meter Stick 1. Metric System B. What is the basic unit of length? What do you use to measure it? Meter Meter Stick

1. Metric System Liter Graduated Cylinder or beaker C. What is the basic unit of volume? What do you use to measure it? Liter Graduated Cylinder or beaker

Celsius Thermometer 1. Metric System D. What is the basic unit of Temperature? What do you use to measure it? Celsius Thermometer

2. Unit Table Base Unit What it Measures Abbreviation Gram Mass g Meter Length m Liter Volume l Celsius Temperature ˚C

Which of the following is NOT a unit of the metric system? Centigram Kiloliter Mile Meter

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

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

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

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.

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?

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

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

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

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

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

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

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

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!

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

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

15. Inference vs Observation

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

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

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

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

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

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

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

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

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

27. Time that winds were 20 mph? 11 am

28. Wind Speed at 3 pm? 15 mph

29. Average 5 + 10 + 20 + 25 + 15 + 10 = 14. 17 mph

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