See how you level up against professional engineers, designers, and inventors!

Challenge 1:

What’s the steepest hill you can climb?

Use a piece of wood, or anything you can find for a ramp, and stack books at one end to adjust the angle. Use a protractor to measure the angle.

Experiment with different gear ratios, motor power (knob setting), and feel free to use your own wheels or other parts.

To submit, post a video of your experiment to your favorite video sharing site (i.e. Facebook, Vine, etc.), and email us the link along with your first name, hometown/state, and angle-steepness result to university@myatoms.com.

If you don’t have a protractor, you can get triggy with it by measuring the length of your ramp, and the height at the end of the ramp. Then go to wolframalpha.com (an online calculator), and calculate for “arccos(height/lengthOfRamp)” to get the angle.

Challenge 2:

How fast can you cover a 10 foot drag strip?

First, measure out your 10-foot drag strip, and mark the start and finish lines with some kind of mild tape (like masking tape).

Second, get your stop watch ready. Most smartphones have a stop-watch feature.

Third, run your test! This is a “flying-start” test, meaning that you should start your car far enough before the start line, so that it’s already up to full speed when crossing the start line.

Experiment with different gear ratios, motor power (knob setting), and feel free to use your own wheels or other parts.

Bonus question: How fast is your car going in miles/hr (or km/hr)?

To submit, post a video of your experiment to your favorite video sharing site (i.e. Facebook, Vine, etc.), and email us the link along with your first name, hometown/state, and your course time in seconds. Email submissions to university@myatoms.com.
