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 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 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...

In this Cartesian diver lab, learners explain using text and diagrams how the Cartesian diver works. Students evaluate ways in making their lab design better. Learners make predictions of how changing the variable would change the...

Students investigate surface tension and bubbles. In this scientific inquiry lesson plan, students explore how the surface tension of water is able to support tiny objects that actually weigh more than the water as they collect date by...

Young scholars conduct an experiment to simulate an oil spill and identify the characteristics of oil in water. They evaluate the effectiveness of various cleanup methods. They discuss the how to clean up an oil spill, and what causes...

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.

In this elements, compounds, and mixtures worksheet, students answer questions about the properties of elements, mixtures, and compounds. Students identify the physical changes that is made to a substance to determine if it is an element.

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.

For this hot and cold water worksheet, students use hot and cold water to experiment and see what happens when the two mix together. Students also answer 7 questions.

Students consider the concept of ocean pollution. In this ocean lesson plan, students participate in a hands-on demonstration in order to replicate an oil spill and its effects on marine life.

First graders investigate the changing states of water.

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

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.

Students create a Cartesian diver out of a bottle of water and a condiment packet (soy sauce, ketchup, etc.) They observe what happens to the packet as they squeeze the bottle and determine which types of condiment packets make the best...

Learners research the development and implementation of a research vessel/vehicle used for deep ocean exploration. For this oceanography lesson, students calculate the density of objects by determining the mass and volume.

Students work together to create a watershed model. They discover the flow of surface water on different topography. They examine how materials originate from miles away and end up in a different wetland.

Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...

Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.

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...

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.
