Does it sink or float?

Use a collection of familiar objects to determine whether each will sink or float in water.

  1. Gather a collection of objects
  2. Drop the objects into the water one at a time and note if they sink or float.
  3. Document your observations using drawings or photographs.

What did you observe about the items that sink versus those that float?

  • Are they bigger?
  • Do they feel heavier?
  • Do they have a certain shape to them?

Bruce is testing his theories about the different objects that sink and float in water. He noticed that some of the objects just sink as soon as they are put into the water. He found out that his LEGO fleet was able to float! Finally, he created his own water park😄!

Leming the Scientist:

Leming is planning a science experiment.

He has 2 groups of materials.

He would like to find out which group of materials will sink and float.

Here is group 1 and group 2.

Can you guess which group of items will sink and which group of items will float?

Leming has been testing the materials in his 2 groups to see if his theories were correct.

What do you think he learned from his experiment into sinking and floating?

Were your predictions/guesses correct?

  • observe carefully
  • organize information
  • test developing theories through experimentation
  • seek information
  • record observations—drawing and photographs
  • analyse and interpret information
  • express oneself using words and sentences
  • use mark-marking to convey meaning
  • document information and observations in a variety of ways
