Learners design, build, and test the specifications (water displacement and load line) for a model boat. The lesson focuses especially on integrating design principles with inquiry-based experimental skills.

Young scholars have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend...

Students perform experiments to see if items will sink or float. In this sink or float lesson, students work in groups to make predictions, and record the results. After the experiments are complete students make a book of the results.

Students inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Students check...

First graders discuss why some things sink and some float after dropping a variety of items into water.

Students listen to a PowerPoint presentation and complete a Venn diagram comparing the methods of transportation in the early 1800s with today's transportation. They experiment with the buoyancy of keelboats.

Students research inventors and inventions and their impacts. In this invention lesson, students research inventions and their affects in good and bad ways.
