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 explore the relationship between mass, volume and density. They use model boats to discover how changing mass and volume affect density. This is a very engaging lesson which provides great demonstrations and hands-on activities.

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

Students experiment with objects of different densities. In this density lesson plan, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density...

Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

Young scholars experiment to find which liquids are more dense.  In this density and mass instructional activity, students predict and then test objects to observe and measure their density. young scholars observe which items sink...

Students participate in a science experiment to understand that matter takes up space.  In this matter lesson, students experiment with solids, liquids and gases to recognize that matter is everywhere. Students make observations and...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

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

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 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 experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed instructional activity...

Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

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.

Young scholars investigate what matter is and how it changes states.  For this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Young scholars...

Students examine how a hot air balloon works. In this hot air balloon instructional activity, students do an experiment to test the effects of heat on density. Students make their own hot air balloon and act out how nitrogen moves when...

Students observe fluid motion. In this Physics lesson, students explore the principles of Pascal, Archimedes, and Bernoulli. Students list their experiences with fluid movement.

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 explore physics by conducting a class experiment. In this density lesson plan, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five...

Students explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Students define other scientific vocabulary terms and conduct a motion...
