Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

Learners design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

First graders investigate the changing states of water.

In this density worksheet, learners read a selection on density and answer 10 questions using the information from the selection.

Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

In this layer of the earth worksheet, students label and color each layer of the earth. Then students are asked to describe each layer below.

In this seasons worksheet, students cut out the picture cards at the bottom of the page, sort the pictures and paste them with the matching season.

In this worksheet on the life cycle of the butterfly, students look at 4 pictures representing the life cycle stages, and choose words from a word box that match each picture. Students then number the pictures in the correct order of...

For this density laboratory worksheet, learners complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

For this density worksheet, students explore an internet program called Gizmo where they do an experiment with density. Students complete 18 questions.

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.

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 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 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.

Learners determine whether an object will sink or float by comparing its density to the density of water.

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the activity, students will understand that density and weight are different and that density matters in floatation. They...

Students investigate water by estimating how long it takes to freeze, then see if the ice cube will float in water, and eventually work with other items to see if they sink or float in water.

Students will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...

This investigation introduces the concepts of volume, mass, and density and how they interact. Students will make predictions of whether an object will float or sink after finding mass and volume of an object.
