What does it mean to sink?Quack the duck was always telling the fish in the pond

about the wonderful world above the water. One of the fish

wanted to go to the surface to see the world, but the others

warned him it was not safe for a fish out of water. So, the

fish decided he wanted to make a fish museum under water

to admire objects from the world. Quack agreed to bring the

world to the fish. He found an old book and threw it into the

pond and watched it sink all the way to the bottom.

Next, Quack swam to the middle of the

pond and dropped an apple into the

water. He was surprised when the

apple popped right back up out of the

water and he watched it float on the

surface of the pond.

Why do things sink or float?Later, Quack dropped a shoe into the pond and

he watched it sink down to the bottom of the

pond. It landed next to the bicycle, potato, and

bowling ball that he also dropped into the pond.

After that he dropped an acorn into the pond

but it wouldn’t sink. It just floated at the surface

of the water. He noticed that the solid things

went straight to the bottom, but the hollow

things with air inside of them floated.

Do you think a heavy object will always sink in water? Will a light one always float?

Quack found a heavy stick and a light rock. He

couldn’t wait to show the fish. They had NEVER seen

a real tree before! The stick was so heavy he needed

beaver’s help to drag it to the pond, but the rock was

so light he carried it all by himself. When he dropped

the little rock and the big stick into the water the

rock sunk down to the bottom, but the stick floated!

He couldn’t believe his eyes!

Do you think a heavy object will always sink in water? Explain why you feel this way.

Will a light one always float? Explain why you feel this way.

What else do you think might float? What else do you think might sink?

Finally, Quack brought a sponge and a balloon. At first, the

sponge floated on the surface of the water. But then, it started

to fill with water and sank to the bottom of the pond. “That

was strange!” he thought “first it floated and THEN is sank.”

The final piece of the museum was the balloon. He couldn’t get

it to sink! So, he had to swim down to the bottom of the pond

and hold on tight to the balloon string. Every time he tried to

talk, the balloon would float out of his mouth and go right back

up to the surface.

Why don’t things sink or float on a table, or on the floor? What evidence do you have to support your answer?

What else do you think might float? What do you think might sink? Why?

Directions: Using your science response journals, write your prediction about each object. Do you think it will sink or float. Explain WHY you have chosen your answer.

First, Quack threw a book in the

pond. Then an apple, and before

throwing in the shoe, he had

already thrown in a bicycle,

potato, and bowling ball. Next, he

threw in an acorn, a stick, a rock

and a balloon.

Quack wants to figure out how many things floated and how many things sank by using tally marks. The fish do not understand how tally marks work. Draw tally marks to show how many things floated and how many things sunk. Explain how you used tally marks to represent the information.
