Float or Sink Experiment in P2⛵

20th May 2026
As part of Primary 2's WAU topic 'Under the Sea', we have been working hard at home to create our very own boats and today it was time for our big boat experiment!⛵️🌊✍🏼

First, we spent our morning doing Show and Tell. We talked about our boats, what they’re made of, what they’re called and who helped us make them.

Second, we made predictions on our own boats and then our friends, on whether or not we thought they would float or sink.

Next, it was time to put them to the test! We then recorded our results and talked about which materials floated best.

What an exciting day being engineers & scientists in Primary 2! 🔧🥼
