Floating and Sinking

This week we've been learning about floating and sinking.We have been writing experments about things could float and others sink. Here is a list of stuff sink or float.

And we have lost of questions you might all ready know some of these questions or you might need to search it up. I only have 3 question

1. How can life jackets keep you afloat?

2. Who had the idea to make life jackets?

3. Why do people go underwater and discover sea creatures?

I think that heavy things sink and some light things float because the heavy objects is pulling itself down to the deep surface. Actually, Genisis and Morehu have practice making boats in the weekends.
