Students first thought of a question. |
How can you make a helicopter slower? |
Students came up with a hypotheis. |
I think a helicopter with more weight will be slower because... |
Students then listed their materials. |
To complete this activity students need paper and paper clips. |
Next students wrote a procedure. |
Finally students were ready to start testing. |
Students used timers to record how long it took their helicopters to reach the ground. |
Students then recorded their results. |
Students did three trials. |
Gravity pulls the helicopter down. |
Gravity is the force that makes the helicopter move.. |
Slower helicopters have more air resistance. |
Students will then check if their hypothesis was correct. |
Finally, students are ready to write their conclusions. |
Conclusions tell what they have learned. |
Students use scientific words in their conclusion. |
Students use measurement in their conclusions. |
