"The Sinking and Floating of Plasticine in Water" Sinking and Floating PPT

Part One: Observing the ups and downs of plasticine

Put a piece of plasticine into the water and watch it float.

Shape a piece of plasticine into various solid shapes, place it in water and watch it rise and float.

Changing the shape of the plasticine, ______ does not change, ______ does not change, its sinking and floating state ______ changes.

The sinking and floating of plasticine in water PPT, part 2: Let the plasticine float on the water

Can you think of a way to change the shape of the plasticine so that it floats on the water?

The same piece of plasticine is made into different shapes. Some sink into the water and some float on the water. What is the reason for this?

The sinking and floating of plasticine in water PPT, the third part: Comparing the amount of water displaced by plasticine

Let's measure the amount of water displaced by different shapes of plasticine in water.

We call the volume of water displaced by an object in water the volume of water displaced.

experimental method:

Take a measuring cup, pour 200ml of water into the measuring cup, make the plasticine into a solid ball, put it into the measuring cup, observe the amount of water displaced by it, and make a record.

Then make the plasticine into various shapes that can float on the water, observe the amount of water they displace, and record it in the table.

Precautions:

The amount of water displaced must be measured carefully, and the line of sight should be level with the liquid level when observing the scale.

After carefully observing the liquid level scale, record the data accurately to minimize the error.

Before each measurement, check whether the water volume is maintained at 200ml, and top it up if it is insufficient.

Steel sinks in water, but large ships made of steel can float on the water and can also carry cargo. Can you explain why this is?
