Students determine the density of different substances. In this physical science lesson plan, students rank them according to their density. They discover the relationship between volume and density.

Students integrate history and science while discovering how salinity affects the density of water. After a lecture/demo, students work in groups to complete a lab activity that demonstrates how salinity affects the density of water.

Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

Students investigate how changing pressure affects density. In this physics activity, students explain the relationship between density and pressure. They observe the Cartesian diver in the lab as pressure is changed inside.

High schoolers investigate why some objects float or sink in water. In this physics instructional activity, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

This open-ended boat building exercise is meant to be part of a three-lesson 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 line...

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

Oceanography experts use candy to construct a model of a bio-physical mooring that would test a variety of factors. Each piece of equipment to be included on the mooring is described within the write-up. As pupils gather the candies for...

Learners conduct a series of investigations on the unique properties of water. In this general science activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Pupils research the implementation of a research vessel used for ocean exploration.  In buoyancy lesson students will construct a device that shows neutral buoyancy.

Students conduct a series of experiments on water electrolysis. In this chemistry lesson, students explain what happens to the molecules during the process. They cite real world applications of electrolysis.

Students perform a series of tests on water-based paints. In this chemistry lesson, students identify their different functions. They calculate paint density and fractional concentrations.

Pupils explore online tutorial on polymers. In this chemistry lesson, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

Students investigate the carbon dioxide content of different sodas. In this chemistry lesson, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Students role-play scenarios in which they encounter a friend or acquaintance who may have an eating disorder and brainstorm ways to help the friend. They create informational brochures with information about eating disorder prevention.

Students conduct a variety of experiments to explore gel electrophoresis. In this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Learners watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Students identify the characteristics and composition of emulsions. In this chemistry lesson, students classify household products according to emulsion type. They explain how to make the best emulsion.
