Materials and Tools Clear storage tubs to test submersibles in water (buckets or full sinks will also work) Rags and paper towel Building materials that float or sink, e.g. balloons, paddle pop sticks, wooden skewers, dowel, PET bottles, plasticine, straws, pipe cleaners, CDs, nuts and bolts, paperclips, pipettes, cotton reels, plastic or polystyrene cups, core flute, anything else you have in large quantities Water resistant joining and sticking materials (hot glue, string, twisty ties, rubber bands etc.) Scissors Extension materials: syringes & plastic tubing to fit (these can be substituted with a submerged balloon and a straw to fill it with air), aspirin tablets, magnets Lesson Outline 120 minutes – The below lesson outline provides an overview of workshop elements. Please ensure you follow your school WH&S procedures while conducting this lesson. Introduce the Innovation Process, tools, materials and workspace. The challenge will be introduced in stages. You might like to begin by introducing a Introduction few basic ideas about buoyancy i.e. density. See our short activity Fruit Float.” “Does (10 minutes) You may choose to discuss some examples of submersibles (i.e. Deepsea Challenger). Lay out all the building materials on a table. Challenge 1: Scavenger hunt. Ask students to find three objects that they believe will float, three objects they believe will sink and three objects they’re not sure Buoyancy about. discovery (5 minutes) Ask students to test their predictions in the tubs of water. Discussion: In small groups or as a class, students discuss their findings (i.e. What were their predictions? Which discovery surprised them?) Instruct the students to split into groups of 2-3. Buoyancy Challenge 2: Build a raft. Ask students to build a vessel that floats using at least application some of the objects they tested in the scavenger hunt. (15 minutes) Students may wish to supplement building materials with more building supplies.
