In their introductory lesson on sinking and floating, second graders were given the challenge to get three film canisters to sink, float, or stay suspended in a cup of water. Using only washers, they experimented with changing the film canister's contents to reach the goal.
Some students hypothesized that heavier things sink and lighter things float. Is this always true? As we dig deeper into ocean engineering, we'll either prove or disprove this claim!
