Activities

[Contributor - Kripa S]

1. Have small groups make their own pulley. Take two small spools of thread and put a pencil through the center. Then tie the ends of a length of string together to create a loop. Have two students hold the pencils and spools and spin them slowly to create a pulley system. Then have another student write a message and attach it to the thread using a paper clip. Use the pulley to pass the message from one person to the other.

2. Tape a pencil to a table. Then place a ruler on top of the pencil to create a lever. Place an object on one end of the ruler and press down on the other end to lift the object up. Try using objects of different weights. What happens? Is it easier or harder to lift heavier objects? Then have your child move the ruler so that the fulcrum is closer or farther away from the load. When does it become easier or harder to lift the load? Does the load ever become too heavy for the lever, and if so, where is the fulcrum?

Lesson Plan version 1.1 acitivites

1. The students will make inclined planes with boards varying the slope of the board. There will be rubber bands around the book. The students will tie the string to the rubber bands and pull the books up the different inclined planes. They will also pull the books straight up without using the inclined planes. The students will find that it take more work to move an object up an inclined plane with the steepest slope.

2. The students will cut paper with both sharp scissor and dull scissors. They will observe that the sharp scissors will cut better than the dull scissors.

3. The students will make a lever out of the given materials (Wooden ruler, Object to lift, Tape, A can) and explore the relationship of the fulcrum to the load. The students will discovery that it is easier to move an object when the fulcrum is closer to the load.

4. The students will make a pulley with a sewing spool, string, and a pencil. They will use this pulley to lift an object. They will compare lifting the object with the pulley and without the pulley. They will find that it is easier to lift an object with the use of a pulley.

5. The students will push one toy car on its side and the other on its wheels. They will note the difference in distance traveled.
