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

Part One Content: Collaborative Exploration

Observe the rise and fall of plasticine

Experiment name: Observe the sinking and floating of plasticine in water

Equipment needed: Plasticine, water, sink

Experimental steps

Place a piece of plasticine in water and observe its sinking and floating.

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

Changing the shape of the plasticine will not change its weight or volume, and its sinking and floating conditions will not change.

What causes the plasticine to float?

The weight of the plasticine has not changed. The changing factor is that the volume of the plasticine has increased, so its volume immersed in water has increased.

Measuring the amount of water displaced by plasticine

Amount of water displaced: It is the volume of water displaced by an object in the water.

The difference between drainage volume and displaced water volume:

The amount of water displaced refers to the volume of water displaced by an object; the displacement refers to the weight of water displaced by an object.

PPT on the ups and downs of plasticine in water, part 2: expansion and extension

Plasticine is the predecessor of colored clay. Since its advent in 1956, plasticine has become children's favorite toy. The original plasticine only came in two colors: gray and white, but in the following years, plasticine came in a variety of colors and scents, including luminous, gold, silver, shampoo flavor, etc.

PPT on the ups and downs of plasticine in water, part three: summary of this lesson

By changing the amount of water an object displaces, the object's sinking and floating in the water may change. The sinking shape displaces a small amount of water, that is, the volume immersed in the water is small; the floating shape displaces a large amount of water, that is, the volume immersed in the water is large.
