Warm up – What are the Variables in our paper airplane experiment? On the top of your homework do the warm up Warm up – What are the Variables in our paper airplane experiment? Independent – what’s changing? Dependent – what’s being observed? Control – What’s not being changed? Constants – what are you going to keep the same throughout the entire experiment?

REMEMEBR!!! – you ill be graded on this Remember SAFETY RULES ALWAYS APPLY in a lab setting All materials and chemicals are considered to be dangerous NO HORSEPLAY or PRANKS Other classes are in session so you CANNOT be loud If you are not mature enough to participate you will do vocabulary instead and you will make up the lab on your own time

Variables in our Experiment NOTICE!!!! We are not measuring how far you can throw your airplane!!!! We are measuring if mass makes it go further, not force!! Control your throw Variables in our Experiment Prediction: I think adding paperclips will make my plane go further. Hypothesis: If I add two paper clips to the front of my paper airplane, then it will travel further, because the paper clips add mass. force = (mass) x (acceleration) 0.5 grams Throw Weight of paper speed of airplane

At the top or YOUR procedure’s paper assign and write the following roles of each group member Thrower __(Group member’s name)___ They will throw the plane EVERY TIME and create the plane. Recorder _(Group member’s name)_ Will be responsible for recording the information Spotter _(Group member’s name)_ Responsible for measuring how far the plane traveled & telling the recorder Time Keeper _(Group member’s name)_ Pays attention to teacher, informs group, watches time

Observations: 1 2 Data Table with measurements from the experiment. 3 # of paper clips Flight Distance (m) 1 2 3 4 5 6 Data Table with measurements from the experiment. Include headings and labels.

Procedure: How are we going to perform the experiment? Line up outside Rotate plane throwing group Recorders record Throwers, throw Spotter reports the measurements of the plane Time keeper helps the spotter and watches clock The furthest traveled plane wins bonus points on first test

Experiment Day Get paper clips, lab paper and a meter stick. Make the paper airplane. Make sure you follow directions. Gather materials and head out to your assigned runway. Fly your airplane, measure flight distance, and record your data in your notebook. Remember to add ONE paper clip each time.
