1. Will it float or will it sink?

2. Lesson 1

3. What are the words we use to talk about when things are held up in water or fall to the bottom?
FLOAT
Sink

4. Some objects stay on top of the water – this is called floating
sinking
Other objects fall to the bottom – this is called sinking

5. stone is heavier than water so it sinks to the bottom

6. Meanwhile, the air inside floating toys is lighter than the water, which makes the toys buoyant and keeps them above the surface.

7. You can not always guess which object willor
You must test them to find out
Lets experiment!
float
sink

9. ‘Will it Float?’
(Sung to the tune of ‘When the Saints Go Marching In’)
Oh, will it float or will it sink? Which will it be; what do you think? Will it stay on top of the water? Or, like an anchor, will it sink?

10. L.O: To predict which objects will float or sink.

11. Lesson 2

12. Now lets see which items float and which sink
Now lets see which items float and which sink! Will your predictions be correct?

14. L.O: To test which objects will float or sink.

15. What did the results show?
My results show that my predictions were all correct. My results show that my predictions were mostly correct. My results show that my predictions were not correct.

16. Lesson 3

17. Lets make our own ships!
We are going to make our own ship out of foil and see if it floats or if it sinks! It has to carry the weight of one small rock without sinking! Lets get planning.

18. What design will you use?

19. L.O: To design an object that can float.
This is my ship. I think it will float because

20. Next week we will make and test these ships!!
