can you suggest me some improvised models that can be used for teaching physics?

Question

can you help me to prepare some innovative work regarding the subject physics or chemistry?

Answer 1

Generally speaking, physics related to daily life is more memorable than abstract physics that cannot be sensed...like atomic physics for example. So here are some cool things you can do:

1. Use a slinky to show how waves travel along its length when you shake one end and someone else holds the other end. You can show that energy ~ square of the amplitude by shaking the one end with increasing amplitude so the person at the other end feels that increase in energy when the wave reaches her.

2. You can show how static friction keeps a block on an inclined ramp from slipping down the ramp. You can show how the coefficient of static friction varies with the material of the block. Simply use blocks of different materials, but the same dimensions, and gradually increase the slope of the ramp until the block moves. Note the angle of the slope when each block begins to move. The angles will indicate the variations in the coefficients of friction for each block...higher angles mean higher coefficients.

3. Drop a bowling ball and a golf ball from the same height at the same time. Note that both hit the floor/ground at the same time. This demonstrates that the rate of acceleration/fall is the same regardless of the weight of a body. That is W/M = g = w/m; where the big letters are the weight and mass of the bowling ball and the little w and m are for the golf ball.

4. Heat a metal can as hot as it can stand. Then, making sure you don't burn yourself, put an air tight cap on the can and let the can cool down. Eventually the can will begin to crumple as though some giant hand were crushing it. That giant hand is, of course, our atmospheric pressure pushing down on the can which has lower pressure now on the inside as it cools down because the air inside was evacuated via the heating process.

So there you have four easy to do, every day physics experiments to show waves, friction force, force of gravity, and atmospheric pressure (force).

Answer 2

on account that no one else has so some distance (edit: on the time I typed this... whoops), i'm going to take selection 2! finished call: Jason Michael Calhoun Age: 19 region: New Hampshire Siblings (if any): One youthful sister, Bethany (sixteen), and one 0.5 brother, Colten (4) Lives with: he's in college. He lives off campus with 2 roommates, Brandon and Skylar. Pets (if any): His condominium would not enable pets, nonetheless Sky did have a puppy fish at one factor, which Jason and Brandon forgot to feed while Sky became into traveling residing house for a weekend. So it fairly is ineffective. His dad has a golden retriever named Bucket. courting status: single.

Answer 3

Let's see--to learn about torques we made ice cream with a hand crank ice cream maker, to learn about collisions we used hot wheels cars on tracks, and to learn about the doppler effect we drove a car and honked, listening and trying to match the pitch of the car. We did some others but I can't remember them off the top of my head (that was like 6 or 7 years ago!).

You can check up this website http://www.plenrich.com and click onto "scientific kits" to see some of the kits you can use to teach Physics.
Or email Mr Peter S P Lim at [e-mail] for more pictures of kits not shown above.
There are electromagnetic kits as well as energy conversion kits available.

Answer 5

prepare pratical work and show it
