How Dense Are You?

Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Students observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the density...

Young scientists explore many different types of energy including light, heat, nuclear, sound, potential, and more. They match the types of energy and identify when energy transfers from one type to another.

Students perform an experiment to measure the density of tap water vs. salt water.

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Students identify different woods based on their density. In this density lesson, students use a triple beam balance to find the mass and a metric ruler for the volume. They look through various wood blocks and identify what type of wood...

Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

Young scholars explore mass and volume. In this mass and volume lesson, students pretend to be on a hike and have lost their way. Young scholars must cross a river get back on track. Students must use mass, volume, surface area, density,...
