2 Part Question: 1. Read each description of supplies the student is using to conduct their experiment. Come up with a testable question they could use for their investigation. • Ramp, tennis ball, golf ball, ping pong ball, meter stick • 20 cm high ramp, 40 cm high ramp, 60 cm high ramp, toy car, meter stick
What type of ball would roll the farthest? How does height of a ramp affect distance a toy car will travel?

6. Explain the difference between a rotation and a revolution.
A rotation is an object spinning on its axis (imaginary line). A revolution is one object going around another (following its orbit).

Tom and Rex were asked to lift the weights above. Tom was able to lift the bar above his head while Rex was only able to lift the bar to his waist. 4. Which person applied the greatest force to lift the weights? Explain
Tom applied the greatest force because he was able to lift it higher.

7. The sun appears to travel across the sky from _____ to ______.
east to west
200
16. What do the earth, sun, and moon have in common?
All spherical and all have gravity
200
12. What would happen if Earth’s rotation were to speed up?
Days would be shorter
300
3. What are the limitations to using the flashlight in the above model?
The flashlight only shines light in one direction when the sun shines all the way around

Tom and Rex were asked to lift the weights above. Tom was able to lift the bar above his head while Rex was only able to lift the bar to his waist. 3. What force is having an effect on the weights?
gravity

9. Draw an illustration of how your shadow appears at different parts of the day. Be sure to include the sun.
Draw on board

14. Earth and other planets are able to be seen in space because _______________.
they reflect the Sun’s light
300
13. What would happen if Earth’s rotation were to slow down?
Days would be longer
400
2. What do the arrows represent in the model?
The rotation of the Earth counterclockwise

Tom and Rex were asked to lift the weights above. Tom was able to lift the bar above his head while Rex was only able to lift the bar to his waist. 5. Which person applied the least amount of force to lift the weights? Explain
Rex applied the least amount of force because he was not able to lift past his waist.

10. Explain why your shadow changes throughout the day.
As the sun rises it creates a long shadow on the opposite side of the object. The sun gets higher in the sky and the shadow gets shorter. When sun sets, the shadow is long again.

18. What do the Earth and the Sun share?
Both have objects that orbit them

2. Holden and Hunter are supposed to come up with a testable question to perform a scientific investigation in class. Each boy has their own idea and they must decide on one. Which testable question could be answered by conducting a classroom experiment? Justify your reasoning. • Holden – How does temperature affect the amount of lava that comes out of a volcano? • Hunter – Which surface would allow a ball to roll the farthest?
Hunter’s question could be tested in class. Temperature of a volcano could not.

7. Students were asked to write testable hypothesis on an experiment they were conducting in class. The teacher explained they would be creating balloon racers using some fishing line, a straw, tape, and a balloon. Students will blow in the balloon 3 times and release the balloon racer on the fishing line. They will then repeat this for a total of 3 trials. Students will repeat this experiment with 6 puffs of air and then 9 puffs of air. They will measure the distance and then record their results in a table. Which student has the best written hypothesis? Justify your reasoning. • Joe – Air makes the balloon racer go fast. • Sue – If you blow more air into the balloon, then the balloon racer will go further. • Josh – The balloons will go the same distance every time. • Jessica – The balloon racer moves on the fishing line.
Sue has best hypothesis because it’s testable and measurable

8. Why does it look like the sun moves across the sky?
Earth’s rotation on its axis

6. Explain why using materials appropriately is extremely important when conducting a scientific investigation.
Using materials appropriately is important for safety and also for accuracy of results.
