Is there a science working model for class 8?

Answer 1

MODEL FOR NEWTON'S THIRD LAW OF MOTION

Material:

4 pins

Styrofoam meat tray

Cellophane tape

Flexi-straw

Scissors

drawing compass

Marker pen

Small party balloon

Ruler

Procedure:

1. Using the ruler, marker, and drawing compass, draws a rectangle about 7.5 cm by 18 cm and four circles 7.5 cm in diameter on the flat surface of the meat tray. Cut out each piece.

2. Inflate the balloon a few times to stretch it. Slip the nozzle over the end of the flexi-straw nearest the bend. Secure the nozzle to the straw with tape and seal it tight so that the balloon can be inflated by blowing through the straw.

3. Tape the straw to the car as shown in the picture.

4. Push one pin into the center of each circle and then into the edge of the rectangle as shown in the picture. The pins become axles for the wheels. Do not push the pins in snugly because the wheels have to rotate freely. It is okay if the wheels wobble.

5. Inflate the balloon and pinch the straw to hold in the air. Set the car on a smooth surface and release the straw.

Answer 2

Make a model in the shape of a volcano. Put a little baking soda into the vent and then pour in a little vinegar (not too much or it'll blast!!). You can see the volcano 'erupting'..

It's as simple as that!!

Answer 3

u can make many things

as u said a simple one i would suggest u to make a model relating to friction

things needed: a toy car , a smooth surface, a rough surface

procedure: take a car and push it on the smooth surface mark the place it reached now do the same for the rough surface .

observation: u would observe dat the smooth surface is having less friction than the rough one

Answer 4

To construct a working model of Physics class 12 level, you have to refer to the teacher's guide. The teacher's guide provides how the construction should be done based on the current curriculum.
