Description

"Does an object sink or float in water?" Sink and float PPT

Part One: Observing the ups and downs of objects

Put the bricks and wooden blocks into the water and observe their sinking and floating in the water.

Precautions:

1. The object must be gently put into the water from the water surface, and the object must be completely immersed in the water. The object must not be thrown into the water or placed on the water surface.

2. The phenomenon of objects touching the bottom of the container in water is called "sinking"; the phenomenon of objects not touching the bottom of the container is called "floating".

Whether objects sink or float in water PPT, Part 2: Observe the sinking and floating of more objects in water

Precautions:

1. Look at it with your eyes and touch it with your hands. Quickly predict whether an object will sink or float in water and fill in the prediction and reasons in the form;

2. Conduct experiments to verify the results;

3. Fill in the results in the experiment record sheet.

Comparing our predictions with experimental results, which predictions were correct? Which ones are incorrect?

Organize the reasons for your prediction and think about what factors may be related to the ups and downs of objects?

Whether objects sink or float in water PPT, Part 3: Observe the sinking and floating of objects made of the same material in water

If the same material changes its weight and volume, will its sinking and floating in water change?

Rubber is _____ in water.

Will there be any change if the eraser is cut into half, quarter, or eighth size? Speculate what would happen if you cut it smaller.

Carrots are ____ in water.

Will there be any change if the radish is cut into half, quarter or eighth size? Speculate what would happen if you cut it smaller.

What conclusions can we draw from the above experiments?

An object made of the same material will not change its state of sinking and floating in water if its weight and volume are reduced.
