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.

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

Pupils investigate how the density of water changes the buoyancy of water. Students create a hypothesis about what will happen when placing the egg into the water.Pupils can research online different bodies of water (The Red Sea, The...

Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the instructional activity by...

Students investigate how water goes from a solid to a liquid then back again.  In this experimental lesson students conduct their own experiment and see how water changes form. 

The centerpiece of this lesson plan is a predator-prey simulation in which colored paperclips represent different species of animals camouflaged against a colored background. Relevant follow-up questions are provided. The activity is...

In this antonyms and synonyms worksheet, students look in two short poems by Joseph Ceravolo to find opposite or contradictory statements that express many sides of a feeling. Students answer 25 short answer questions about the poems.

Examine two works of art and use these pieces as inspiration for dialogues. The whole class discusses Renoir's Lunch at the Restaurant Fournaise and Toulouse-Lautrec's At the Moulin Rouge. Then, in groups of either three or ten, pupils...

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

In this Archimedes' principle instructional activity, high schoolers answer 13 questions about the concepts of Archimedes' principle such as water displacement, buoyancy and force. The answer questions from a lab they did in class to...

  Students build boats out of clay to test the buoyancy of the boat in water.  Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.   

In this buoyancy worksheet, students read about neutral buoyancy and that the downward force of gravity is equal and opposite to the upward force of water. They answer four critical thinking questions about buoyancy.

Students investigate Archimedes' Principle and show how it relates to density. In this Archimedes' Principle lesson plan, students experiment with a beaker of water, a Styrofoam "boat" and a weight. They predict what will happen when the...

Students experience the magic of mirrors. In this reflection and illusion lesson plan, students witness magic tricks that work because of mirrors, then rotate through five stations to complete hands-on experiments using mirrors, light,...

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 density demonstration, students compare a can of diet coke to a can of regular coke. They list the similarities and differences of each prior to the demonstration. The cans are placed in a tank of water and students record their...

First graders identify forms of pollution and describe effects that various pollutants can have on people, wildlife, and plants; students describe relationships between various forms of pollution and human actions.

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

Students investigate the presence of specific organisms in a freshwater habitat to determine the quality of that habitat. They conduct a field study and distinguish and classify organisms found during the field study.

In this scientific models worksheet, students will use a model to represent matter in its various states. Students can use a computer graphics program, drawing on paper, or three-dimensional creation. Then students will complete 3 short...

Learners investigate adhesion, cohesion and surface tension. In this molecular forces lesson plan, students observe multiple demonstrations that show surface tension, the attraction of water molecules to each other and the ability of...

Middle schoolers observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the...

For this plate tectonics worksheet, students review concepts such as the types of plate boundaries, the concept of continental drift, sea-floor spreading, earthquakes, and plate tectonics. They match 30 terms with their definitions.

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