8 th Grade Science Do Now Make the weekly Do Now on page ___. Describe in 2-3 sentence what is being tested in the following experiment and what conclusions can be made. Ellie wants to know how much light her plant needs. She puts all of the plants outside at 11:00am, she leaves Plant A outside for 2 hours, Plant B for 4 hours, and Plant C for 6 hours. She gives each plant the same amount of water at 9:00am everyday. She notices that Plant A grows the best. Monday, April 29, 2013

8 th Grade Science Helicopter Lab Problem: How will changing the direction that the paper helicopter blades are folded affect the “flight” of the helicopter? Monday, April 29, 2013

8 th Grade Science Helicopter Lab On your handout, write a suitable hypothesis. A hypothesis is an educated prediction about how the independent variable will affect the dependent variable stated in a way that is testable. This should be an “If…then…” statement. Remember, your hypothesis should be a possible answer to the problem question and it should be based upon what you already know about a topic. Monday, April 29, 2013

8 th Grade Science Helicopter Lab Once you’ve made your hypothesis, you should test it for accuracy. Stand on a chair and hold your helicopter by the “T” at shoulder level. Drop the helicopter and note whether it spins clockwise or counterclockwise. Repeat this test several times. Record your observations in your handout. Monday, April 29, 2013

8 th Grade Science Helicopter Lab Refold the blades so that the square on section Y shows when you look when you look down on top of the helicopter. Stand on a chair and hold you helicopter by the top of the “T” at shoulder level. Drop the helicopter and note whether it spins clockwise or counterclockwise. Repeat this test several times. Record your observations in your handout. Monday, April 29, 2013

8 th Grade Science Helicopter Lab Read the following paragraph and then answer the conclusion questions that follow using complete sentences: Bonita wanted to know if adding mass to her paper helicopter would affect how long it would stay in the air. She predicted that adding some would help to stabilize the helicopter and keep it in the air longer than a helicopter without extra mass. She experimented with different numbers of paper clips attached to her helicopter. Monday, April 29, 2013
