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...

Third graders conduct an experiment. In this floating and sinking liquids activity, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

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....

Students work in groups to compare the density of different liquids.  In this density lesson, students use cooking oil, liquid detergent and water to measure density.  Students record their results and check the accuracy of...

Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different...

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...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

Students study flavinoids and how they exist in the plant kingdom.  In this pigment lesson students complete a lab activity to see how flavinoids move in substances then record their observations.

Young scholars develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Students use forensic science to positively identify any suspected drugs submitted to the laboratory. They determine the identity of the drugs found in the bodies of drug-overdose victims. Students use TLC to identify the active...

Students explore how hail forms in the atmosphere, why hailstones are layered, and what accretion is. They also learn what supercooled liquids are.

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Students recognize that density determines whether objects sink or float.  In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their...

Students use thin layer chromatography, TLC, to separate various pigments found in plants.

Young scholars use the scientific method to study Animalia and Plantae Kingdoms. For this science inquiry lesson, students watch a PowerPoint about science process skills. Young scholars complete the National Geographic bottled...

Middle schoolers use TLC separations to identify various substances.  In this chlorophyll lesson students separate pigments found in different plants.

Students identify and complete activities about the structure of the Earth. In this Earth structure lesson, students view a Powerpoint about the Earth's layers and complete a diagram. students compare temperatures in the Earth's layers...

Young scholars study soil and how particle and pore size affect water movement.  In this soil instructional activity students complete a lab activity to investigate pore saturation and sponge like behavior. 

Students observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

Students explore convection. In this lesson plan on heat and energy, students investigate how heat moves in convection currents. They use their finding to better understand how convection currents effect the movement of tectonic plates.

How did the earth become the mass that it is now? Your young scientists explore this question through the concept of density. Their inquiries consider the impact of gravity on the formation of planets. The culminating activity of the...
