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.

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.

LAFS.1.W.2.5 - with guidance and support from adults, focus on a topic, respond to questions and suggestions from peers, and add details to strengthen writing as needed.
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.
