We have been investigating BUOYANCY and learning the science behind what makes things float and sink. We have  carried out experiments and made close observations, explaining the conclusion using scientific vocabulary.

We understand that the density of an item has a lot to do with its buoyancy so we made predictions before our experiment.  We had fun testing a range of items to see if they would float – we were quite surprised by a few! Did you know that a paper clip will sink but a can of Diet Coke will float?

After our experiment, Miss Hamilton launched The Clay Challenge. Each group was given 100g lump of clay which sunk when placed in water. The challenge was to make the clay float by changing its shape. We soon learned that even though density is important in making things float or sink, so is the shape of the object. Most groups managed to get their clay to float. Well done!

We worked together and persevered even when our attempts didn’t work…it soon paid off!

We kept trying until we were successful.

We can’t wait to start our engineering STEM Challenge, Building Boats, next week now that we know so much about Buoyancy. We finished the day with a good sing song…thankfully all of our boats stayed afloat!

Science is so much fun!
