First grade Challenge (gifted education) students are continuing to study water and its properties. In recent experiments, they used their buoyancy buckets filled with items to checked to see which items would sink and which would float and what changes needed to be made to allow an item to sink or float.
Additionally they studied water molecules and how they stick together. Students used pipettes (water droppers) to put single drops of water on a penny to see how they joined together. They also tried it with salt water and soapy water to see what did or did not connect.
