Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Learners examine the relationship between density and buoyancy.  In this physics lesson students use Archimedes' Principle to complete calculations on buoyancy and a lab activity.

Students examine how salt water is more dense than fresh water through experimentation with eggs.

Students observe 2 demonstrations of density. In this density lesson plan, students observe a vial with various substances of different densities. Students then observe the differences between a diet coke and a regular coke can when on a...

In this density worksheet, students answer 12 questions about the density of substances. They read a diagram of a graduated cylinder and determine the volume, mass of water. They interpret a diagram with three liquids and indicated their...

In this salinity worksheet, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.

Students use streaming videos, web sites, and hands on activities students to explore matter. They focus on how temperature affects matter and what the particles look like in the states of matter.

Students participate in a hands on activity simulating an oil spill. In this oil spill lesson plan, students conduct an experiment about an oil spill, discuss how it would affect the environment and provide solutions to prevent oil spills.

Students apply knowledge about density of solids from previous experimentation to this activity which they investigate the density of liquids. They work in small groups to mix water and syrup, and water and oil to see what occurs....

Students complete several cross-curricular activities to learn the letter Ff. In this letter recognition lesson, students complete activities that include geography, music, physical education, science, seasonal, space science, and online...

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

Students investigate different liquids to develop their concept of a liquid. They work at a center to tip, swirl, shake, roll, and otherwise investigate seven liquids in small, clear plastic bottles: plain water, corn syrup, liquid...

Students explore the concept of environmental stewardship. In this science instructional activity, students examine the environmental effects of oil spills as they replicate a contained oil spill and clean up.

In this earth science worksheet, students read a poem about the wind and learn why the wind blows. After reading the poem and informative paragraphs that follow it, kids answer 2 questions regarding the information they read. Finally,...

Students participate in a variety of experiments designed to illustrate types of heat transfer including conduction, convection and radiation. They complete worksheets as an assessment of the experiments.

Students investigate the dirt in the air. In this air quality activity, students use aluminum foil and petroleum jelly to discover if there is dirt in the air. Students discuss results.

Students research inventors and inventions and their impacts. In this invention instructional activity, students research inventions and their affects in good and bad ways.

Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.

Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...

Eighth graders biew each volume container and discuss where they have seen them in their home, and how they have seen them used. They explore the different names of volume sizes and their equivalents towards one another. Students...

Students explore rotating frames of reference, focusing on the weightless environment in space and the Coriolis force.

Pupils create "catchers" that collect dirt particles from the air. They observe the particulate matter that is collected from the air and discuss the effects and causes of air pollution.

Predict and test everyday objects as to whether they sink or float.
