2/11 Examining the effect of rubber bands on cars.
Number of Comments » 6In this lab, the students had to propel their standard cars with rubber bands. Each group manipulated rubber bands in the following ways:
* Stretch the rubber band across to the opposite axle.
* Wind the rubber band in opposite directions.
* Attach the rubber band under, the over the axle.
Some of the students’ observations are listed below:

2-6 Testing vehicle loads
Number of Comments » 0 Lab 5: Observations
For this lab, the students needed to use their knowledge of what made their vehicle move fast and slow from their last lesson to design a fast-moving car of their own.
What made our vehicle move slow:
Heavy Load
No Slope
String got stuck
Not enough washers
What made our vechile move quickly:
Less Load
Clear Path
Correct Design
More Washers
2-4 Examining the effects of mass on an object.
Number of Comments » 0In today’s lab, the students set up experiments to examine the effect mass has on an object while maintaining a constant force. The students added up to two different wooden blocks to their standard vehicles to investigate the effects of a load on motion. During the lab, the students measured the time it took for […]

Number of Comments » 0
Today, the students disassembled their own car designs and built a standard model. Each team of 3-6 students received 16 small weights, a bookend, clips and string. Their goal was to determine the effect adding additional weight would have on speed and distance of their cars.
Predictions:
* Adding extra weight will slow the car down.
* The […]
