Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

This open-ended boat building exercise is meant to be part of a three-lesson plan series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

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