Density

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,...

It's in your destiny to study density! Young scientists conduct an experiment to study the relationship between weight and density. They compare weights of liquid samples of different substances and predict how their densities are...

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...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson plan can stand alone, but is best used as part of...

Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Each group talks about how to test unknown liquids based on their findings in the previous experiment. In this second of four activities, they test unknowns on wax paper, newspaper, and construction paper. As a stand-alone, this lesson...

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,...

A lab activity to show students how different densities of liquid layer on top of each other by using four different colored liquids that contain different levels of salinity. This activity can also be used in an ocean unit where...

Students experiment with a variety of liquids to calculate density. In this integrated science and math lesson, students listen to a story in which the characters must prove and explain why 5 "mystery" liquids react in a certain manner....
