In term 3 the students have been working on the inquiry topic floating and sinking. We have discussed the word density and have experimented with a range of objects to see if they floated or sank. We designed our own soap power boat and it moved from one side of the container to the other. We designed boats out of plasticine and boats out of cardboard and foil. We then tested them to see how many marbles they could carry before the boat sank. We also created our own catamaran, recycling two plastic bottles.
Enjoy looking at our catamarans:
