    1 - Look at the Problem ~2 mins

    Illustration for Look at the problemSome boats carry people and things across the water. Today we will make a little boat that stays up on the water and holds things without falling over. Can we do it?

    2 - Talk and Share Ideas ~2 mins

    How could we make a boat that stays up on the water and holds counters? Share one idea with your partner. Then we will hear a few together.

    3 - Make Our Boat ~12 mins

    With your partner, make one boat from foil and lolly sticks. You may use a little modelling clay to hold parts together. Remember: sides up, and a space inside for counters.

    4 - Float and Add Counters ~6 mins

    We take turns at the water trays. When it is your turn, put your boat on the water gently, then add counters one by one into the middle, and stop as soon as the boat tips or water comes in.

    While you are waiting at your tray, watch the boat that is being tested and count out loud with everyone else, so you all know how many it held.

    5 - Improve the Shape Once ~5 mins

    Dry your boat on a towel at your table. Then change the shape once: turn the sides up higher.

    Then take turns at the water trays again for a quick try. What do you notice?
