Layer the Liquids

A classic investigation on the density of liquids is explained for you in this lesson plan. Te begin, you prepare water samples of different salinities and then add different food coloring to keep them separated and easily identified....

Using a graduated cylinder and triple beam balance, middle schoolers measure the volume and mass of four different liquids. They use the values to compute densities. In a separate activity, they experiment with Cartesian divers and learn...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

In this earth's layers worksheet, students learn about the 3 different layers of the earth: core, mantle and crust. They then use this information to answer the 16 questions in the packet. The answers are all on the last page.

Students research physical science by creating a model in class. In this earth layers lesson, students define the Earth inner and outer core as well as the crust and their characteristics. Students utilize clay, marbles and a knife to...

The densities of a variety of liquids are demonstrated in this simple, yet effective experiment. Liquids such as honey, dish soap, cooking oil, water, rubbing alcohol, and corn syrup are put on top of one another in a large beaker,...

Students compare the relative densities of different liquids, first by layering them on top of each other, and then by weighing equal amounts of the liquids. They explore the density of air versus the density of water.

In this earth science worksheet, students read about the characteristics of the Earth's layers such as the mantle, core, and crust. They answer 10 mixed type questions using the online application.
