Students find the density of objects by finding their mass and their volume. In this density lesson plan, students determine the mass of objects, the find the volume by using formulas or by water displacement and they calculate the...

Middle schoolers learn how to measure the density of metals. In this density of metals lesson plan, students measure the density of various metals in order to determine what metals were substituted in a king's crown, scepter, breast...

Students investigate matter. In this physical science lesson plan, students will learn about matter, physical states, and reactions. There are a series of four lab activities that will be conducted.

This lab activity does not have to be done with AP environmental scientists. It can also be done with middle to high school earth scientists. The procedures aren't complex. Learners determine the density of dry and wet sand in order to...

This activity will lift spirits in your class, but there is little scientific explanation for what makes a hot air balloon rise. As you are teaching middle school scientists about density and convection, you can incorporate this...

Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.

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...

Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

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.

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

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...

Using a stream table, erosion enthusiasts examine how the density of sediment and how the slope of land contribute to the amount moved by waves. You will not be able to use this entire resource as is; there are teachers' names and...

Learners use an Excel spreadsheet to calculate the density various liquids. They take pictures of their results.

Learners explore the physical properties of density. In this hands-on activity, students calculate density and distinguish between intensive and extensive properties.

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

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

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Young scholars relate the concept of density in relation to the rocks that make up the Earth. They determine the density of various rock specimens and answer assessment questions.

Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.

Students use scientific measuring tools to collect and use scientific data. They determine the density of four different objects by using their data to explain why objects have similar/different densities even though they are both made...

High schoolers observe a demonstration of regular soda versus diet soda.  In this exploring density instructional activity students complete a lab on density and present a PowerPoint presentations of their results.

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 use the scientific method to conduct an experiment and use varied methods to gather background information. They correctly use lab equipment and prepare tables and graphs that organize, conclude, and present their findings. ...

In this Cartesian diver lab, students explain using text and diagrams how the Cartesian diver works. Students evaluate ways in making their lab design better. Students make predictions of how changing the variable would change the...
