Theme

This is our theme work about falling and sinking

Falling and sinking are the same because....

-both involve objects being pulled by gravity.

-both can be reduced by making things wider and flatter in shape.

Falling and sinking are different because....

-objects fall through air and sink through liquid.

-falling is faster than sinking because liquid is thicker than air.

-some objects that fall, don't sink.

We made tin foil boats to make rocks float.

The best designs that held the most weight were the ones that had the largest areas and had high sides. The high sides stopped the water getting in and the large areas stopped the shapes falling through the water.
