Will it float or will it sink?

Today Room 9 read a story called 'A friend for Little Bear'.

The story is about a little bear who is all alone on a desert island.  During the story, little bear finds lots of items floating in the water.

Once we had finished reading the book, Chloe mentioned that big things sink and little things float.  Things then sparked a discussion about things that we thought could float and those that would sink.  

Some of the things that we thought could float were:

"Humans," Alex

"Gas mask," Jamie

"Boat"  Lucas

"Hot air balloon" Savannah

"Swimming ball," Leah

"Trolley," Keira

"Big dolls," Savanna

"Food."

We thought that these things would sink in water:

"Rock," Landon

"Beer bottle," Bradley

"Car," Ava

"Pen," Bryson

"Barbies," Savanna

"Duchess," Jayden

"Paper," Chloe

Later in the afternoon, Miss Powell brought out a tub of water for us to test out some items to see if they floated or not.

We made predictions before we popped them into the water.

We had a great time trying out some items from our classroom, and discussing the results with possible explanations for them.
