Grade 11

This lab is for investigating conservation of momentum. It is a simple lab with a couple toy cars crashing into each other. I used to do this lab with ticker tape, but now we have CBR2 devices to measure the speed of each car.

The specification are attached.

This lab is a very good lab for high school physics.

It makes students think of what needs to be measured in order to find the velocity of a marble sliding across a table and falling off. This is great for the Projectile Motion unit. Also it gives students an understanding of how to keep variables constant (in this case the speed of the marble is kept constant because of the ramp set at a constant angle at a constant distance from the edge of the table).

This lab is designed to investigate the motion of a pendulum, specifically its period. From some initial observations, the students are to collect reasonable data to determine the acceleration due to gravity.

Note: You will need a pendulum setup: a light string connected to a heavy weight on one side and a stationary object high above the floor on the other (like the ceiling), letting the pendulum swing back and forth. The string length should be adjustable.

This lab is designed for finding the static coefficient of friction. Students need to find a way to find the coefficient of friction using simples equipment such as spring scale (newton meter) and a box and some weights.

Attached is a specification sheet for this lab.

This lab is great for analysis of motion graphs (d vs. t, v vs. t, a vs. t) and how to change them one into another in a detailed manner. At the end, the students should find the acceleration due to gravity from the slope of the best fit line of the graph of v vs. t.

This lab, can give really great results (within 5% error) if the students do the right calculations.

Attached is the specifications for this lab.
