Floater or Sinker?

Topic: Floater or Sinker?1.P.1.3. Students are able to predict how common materials interact with water. • Floating/sinking Example: Use items to float/sink: clay,

wood, cork, pencils, crayons, coins, cotton balls, etc.

Video-Will it float or sink?

As we can see from the video, every day things that we wouldn’t expect may float in water while others may sink.

What are something that you think would float? Sink?

From the video…

Here are some examples of things that may float…

Rubber Duck

Life Jacket

BalloonTennis

Ball

Beach BallIce

• Rock• Penny• Bowling Ball• Anchor• Cell phone

Things that will not float…

• The answer is yes! • We can float and sink!• Eggs can also float and sink depending on what water they are in.• Pop/Soda can float or sink depending on what kind.

Are there something things that are can do both?

1. Try to dissolve or mix salt, sugar, toothpaste, oil, etc. in water. 2. Then drop an egg, a penny, paper clip, rubber duck, golf ball, and

rock in the different waters.3. Make a note of which ones float and which ones sink!

Let’s try an experiment, just to be sure..

• What did you find out about the different objects being dropped into the different kinds of water?

• Lets discuss this with our neighbor!

Discussion Time!

• From this experiment we see that the different objects either sank or floated in the water. However, when we put certain objects into the different water, it reacted different.• This shows us that depending on the content of the object and

content of the water, the objects act differently!

From this experiment…

Isn’t learning about different objects in science fun?!

Great Job Students!
