How does the cable car do large class homework?

The method and steps of making the cable car are as follows:

Prepare:

Illustration of manufacturing steps (taking materials and tools-drawing cable car-drilling-assembling), small board, cardboard, 2 cm long straw, shoelaces, marker, drilling machine and scissors (as shown in the figure).

How to play:

1. Children take a small plate according to the picture and put cardboard, straws, shoelaces, markers, punches and scissors on it (pictured).

2. Draw the cable car on the cardboard or design the cable car yourself according to the schematic diagram, cut out the outline of the cable car along the line, find the center position of the upper end of the cable car, punch a small hole with a punch, insert a straw into the hole, and then pass the shoelaces through the straw. After making, check whether the "cable car" can move flexibly on the shoelaces.

3. The children grabbed the ends of the shoelaces with their hands and tightened them, trying to make the "cable car" on the shoelaces slide.

4. Explore ways to make the "cable car" slide without swinging your hands.

Rules:

1. Straighten the shoelaces and let the cable car slide on them.

2. Try to make the "cable car" slide without swinging its hands.

3. Without swinging your hands, try to let the "cable car" slide from low to high, and then slide from high to low.
