Here is a simple experiment where you can collect data from an experiment and predict what might happen next. You can do this with any data so if you were creative enough perhaps you can come up with your own experiment. Either way you will have to decide how to collect data and record it in a data table. Watch this video to see the power of the conclusions you can make from data you collect.
Create many variations of the helicopter above. Be creative in ways in which you can change your design.
Label each helicopter with a letter - or a name!
Drop each helicopter from a number of different heights and record the time it takes to fall in a 2 way table. It might be best to use a spreadsheet for this.
Plot the information on a graph, use technology if you like. Can you fit a line to your points? could you predict a height or time that you have not measured? Test your prediction. You might be able to use something called a regression line.
Evaluate your experiment to determine any faults with your process and repeat the experiment to remove these faults.
Could you use video and a tripod to improve the accuracy of this experiment? Try video physics on your iPhone.
What are the best ways of presenting data?
If you were to collect data from the internet is it as reliable?
Could you use this data to predict anything, for example the weather?
What can you do to reduce error in experiments?
What are the best graphs for this type of data?
How could you use mean, standard deviation and range in this experiment?
Do you know what a box and whisker diagram is? Could you draw one for any given helicopter?
Create a piece of media that explains your experimental and data collection process (print, video, website, digital production, paper display etc)
Present a Q&A session for your classmates
