How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

Young scholars conduct a series of experiments on water electrolysis. In this chemistry lesson, students explain what happens to the molecules during the process. They cite real world applications of electrolysis.

High schoolers observe demonstrations that show adhesion, cohesion, equilibrium density, pressure of gases and solubility. In this gases lesson plan, students observe a demonstration of raisins, spaghetti, and popcorn moving up and down...

Learners explain how melting glaciers affect global warming. In this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.

Students examine the properties in oil in water. In this mixture lesson, students read about the Lophelia II 2010: Cold Seeps and Deep Reef Expedition and look at images of deep sea ecosystems. They experiment or participate in...

Insolubility and density? Yup, it's art class, of course. To create insoluble paintings that continually move and change, kids mix water-based paint with mineral oil and seal the mixture in laminating pouches.

Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

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 lesson outline even...

Students explain that while cities have unattractive features, the density of human life enables energy efficiency, mass transit, recycling, and other benefits which are difficult or impossible in rural areas. This is the fifth in an...

Students explore the basics of interpreting RUSS temperature and oxygen profile data. They are introduced to the Geographic Information Systems (GIS), particularly with respect to interpreting maps.

Students take a hands on approach to learning about conservation.  In this conservation lesson students divide into groups and complete several demos, view a PowerPoint presentation and complete a handout.

Students work together to identify marine debris. They explain the effect of the debris on various ecosystems. They draw different types of ocean currents as well.

Learners have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

Students comprehend that the Cartesian diver is a dropper and the water and air inside it. They vary the volume of the air and the amount of water, the diver can be made to be either more or less dense than water. Pupils squeeze the...

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

Students experiment by creating an oil spill and trying a number of clean up methods. They determine which methods are the least costly and most effective. They role play as an environmental engineer and as an oil company owner who must...

Students are introduced to the concept of buoyancy. The Video used in this instructional activity demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

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

Second graders discuss why some objects float while others sink. They examine various objects and predict whether or not they will sink or float. Students discover the properties needed for objects to float.

Students explain the physical properties of matter. They, in groups, perform a variety of experiments, each demonstrating a different property of matter. A very nice, hands-on lesson!

Students explore an important role of environmental engineers by studying the Exxon Valdez oil spill. They experiment with different strategies in order to clean up their own manufactured oil spill.

Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...

How can you relate colligative properties of solutions to everyday situations? Pupils first discuss the concepts of density, boiling and freezing points, then demonstrate how to accurately determine the boiling and freezing point of...
