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

Students construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

Students examine how a hot air balloon works. In this hot air balloon instructional activity, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when...

Students explore the properties of water. In this cross curriculum art and physical science lesson, students experiment with a variety of materials to demonstrate the cohesive forces and adhesion of water. Students create a water color...

Students explore the densities and viscosities of fluids as they create a colorful 'rainbow' using household liquids. While letting the fluids in the rainbow settle, students conduct 'The Great Viscosity Race,' another short experiment...

Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Students investigate density. In this density instructional activity, students conduct an experiment using food coloring. Students observe the differences in mixing food coloring in water and oil.

Learners explore chemical reactions. In this chemical reaction lesson, students conduct an experiment observing chemical reactions.

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 explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...

An engaging unit on wildfires includes three sections, including a background section with eight lessons and five activities, a field experience section with 13 lessons and five activities, and a conclusion section featuring an...

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

Young scholars engage in this, the third in a three-part series on ships. The overall lesson series is designed to allow students to extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and...

High schoolers write and or present a report contrasting geographic and demographic features (e.g., average annual income, population density, mortality rate, literacy rate) of countries where the target languages is spoken to the U.S. ...

Students make generalizations about weight and mass by engaging in two hands-on experiments. In this weight and mass lesson, students weigh both an empty beaker and beakers with various amounts of weight inside of them in order to find...

Students discover the geography of Earth by analyzing water currents.  In this oceanography lesson, students create visual references on a map of the globe where and why major ocean currents are moving water.  Students conduct...

Students design an experiment to find density using Archimedes' Principle. In this physics lesson, students calculate density using mass and volume. They share their findings in class.

Students investigate how temperature and salinity causes ocean layering. In this ecology lesson, students observe and sketch their experimental result. They report their findings in class.

Students construct their own lava lamp using simple substances. In this physics lesson, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.

  Young scholars build boats out of clay to test the buoyancy of the boat in water.  Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.
