1. Create a flow chartfor creating a paper helicopter and explain it. 2. Record the data of the flight time (3 trials of each paper helicopter). 3. Evaluate and analyse the data using the measure of tendency. 4. Evaluate and explain the spread and standard deviation data. 5. Summarize about your overall results.
