Balloon Car Racers

Task:
Using only the materials supplied to you, design and build a vehicle that is powered only with a balloon. The balloon car challenge is an exercise in technological problem solving: the trial-and-error approach that will also tie in the ideas of motion (distance, time, speed, and acceleration), energy conservation, and forces (friction, etc.).
Materials:

Balloon (supplied by teacher)
4-6 film canister lids or other materials for wheels
three wood skewers - 20 cm of duct tape
600 mL plastic pop bottle (if you want) and 2 Cue-Cards
Scissors

Calculation Requirements:

You must perform at least 10 trials in which you measure the time and distance travelled. Calculate speed for each trial and then find the average speed. Be sure to try and blow up the balloon by the same amount each time.
Using this average speed calculate the average kinetic energy the cart gained during this motion.
Using the law of conservation of energy state the value of the potential energy released by the deflating balloon.
Explain why the potential energy value you obtained is only an approximation? Do you think it is an overestimate or underestimate and why. Discuss sources of error and how they would affect your calculations.
Complete the problems found in the booklet.

Multi-Media Requirements:

Take at least three (3) perspective photos of your car for the “report”
Take at least one video of your car’s performance and post to YouTube to include in the “report” – add a QR Code Link to the video to include in your image section.
Attach the three images and the QR code of the video on one sheet and staple it to this document.

Calculations:
These are part of the package and will be done individually.

Day 78 - Standing Waves

0 Comments

What are standing waves and how do they form? The applet below is a great tool for understanding how standing waves are formed when periodic waves reflect back and interfere (constructively and destructively) with themselves; the result is a standing wave.

Doppler Effect Lessons (Class Lesson & Additional Lesson)

Doppler Effect in 2D

2D Online Calculator

Today we will be learning about the Doppler Effect. Watch the video tutorials below and complete the notes part of the package as well as the example problems. In class we will do a quick recap of the lesson, talk about applications of this (doppler radar, the big bang, police radar, etc.) and work on the problems.

Speed of Sound Investigation

Warm-Up - The Quacking Duck

Today we are going to determine the speed of sound experimentally. Our results should be with 5% of the actual value knowing the ambient air temperature and the equation for the speed of sound.
