Rubric for Balloon Race Car Take Home Lab

Name:______Due Date: 9/30/13

Task: Using your knowledge of forces,mass and motion, design a balloon powered car to go the maximum distance. Problem: How to design a balloon race car for maximum distance?

Hypothesis:______

It must meet the following requirements:

1. Body (chassis): minimum 10.5 cm long x 9 cm wide x 3.5 cm high.

2.Extensions to lengthen the body or support the balloon.

3.No prefabricated wheels.

4.All cars must have at least 3 wheels. If your vehicle has 3 wheels, one pair of wheels must turn independent of the axle.

5.2 sets of wheels: 1 set must spin independent of the axle; the other axle and wheels must be attached and spin with the axle.

6.Once constructed, you will perform 3 trialsconstruct a data table including distance, time, speed and average speed and then write a conclusion.

Rubric for Catapult Take Home Lab Name:______Due Date: 9/30/13

Task: Using your knowledge of forces, mass and motion, and simple machines design a catapult to launch a projectile the maximum distance. Problem: How to design a catapult to launch a projectile for maximum distance?

Hypothesis:______

It must meet the following requirements:

1. Catapult: must be at least 10 cm by 10 cm (base) but not more than 30 cm by 30 cm (base) and have a launch arm not to exceed 30 cm high.

2.Launch mechanism/arm with holder to hold the projectile and some material (rubber band, etc) to cause the launch arm to launch the projectile. NO mousetraps may be used for propulsion for safety reasons.

3. Your catapult may have a triggering mechanism or may be launched by pulling back the arm.

4. Your catapult should be able to launch a small sponge square 0.5 meters or further. Points will be deducted if your launch mechanism (holding device and/or propulsion breaks) or does not launch.

5.No prefabricated kits or sling shot devices.

6.Once constructed, you will perform 3 trialsand construct a data table to show distance traveled, time and speed then calculate the average of the distance and speed attained and then write a conclusion.
