Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...

Ice cores provide scientists with knowledge of historic melt layers, air temperatures, greenhouse gases, and climate stability. Scholars work in groups to build layers representing snow and ice over thousands of years. Then, groups...

Between the time scientists discovered Pluto and reclassified it as a dwarf planet, it did not even make one full revolution around the sun. In two activities, scholars investigate scale models and their properties. Pupils find that it...

Take flight with a fun activity focused on graphing data on a coordinate plane. As learners study the data for Granny's hot-air balloon trip, including the time of day and the distance of the balloon from the ground, they practice...

Don't melt away! Pairs investigate different insulation materials to determine which one is better than the others. Using a low-temp heat plate, the teams insulate an ice cube from the heat source with a variety of substances. They...

Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

In this radon contamination worksheet, young scholars explore the legal and ethical issues associated with radon found in indoor air of homes. Students construct a set of laws that promote fairness to all sellers, buyers and real estate...

In this alchemy worksheet, students read about the early thoughts of alchemists regarding elements. Students are given an experiment done by an alchemist during the Middle Ages and they answer three questions about the experiment knowing...

Students study matter. In this science lesson plan, students examine the relationships among gravity, weight, and mass, the metric measurement of distance and volume, and density and its application to physical properties.

Fifth graders perform experiments to determine the identity of an unknown gas sample. In this chemistry lesson, 5th graders fill balloons with air, oxygen, hydrogen, and carbon dioxide. They use mass and reactivity to identify the gases.

Young scholars are introduced to the basic straight line pattern of travel that light takes. A cereal box and wax paper provide the pinhole camera that captures the light's inverted image. Shifting this pattern provides additional...

Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...

This comprehensive midterm exam covers a vast array of topics typical to high school physics curriculum. Problem solving and mutliple choice questions are incorporated. Review the exam to make sure that the content is suitable to your...

Fourth graders observe a demonstration experiment showing air pressure. They explain air pressure by completing the worksheet.

Young scholars identify and interpret a variety of solid materials - cloth, wood, metal, plastic, paper, and rubber. After a period of free exploration, they then describe the properties of the objects and develop vocabulary in order to...

First graders investigate that air occupies space by performing experiments that show this principle. Students are provided with a lunch bag. Students open the lunch bag and look inside. Students determine if there is anything in their...

Individuals select a plant, illustrate it in their journal, record observations, and create a life story for their plant that accounts for its features and any unique properties. Using these descriptions, a partner attempts to locate...

In this equivalent expressions instructional activity, 9th graders solve and complete 9 different multiple choice problems. First, they determine the expression that is equivalent to the given equation. Then, students write the diameter...

Students examine the factors that influence hurricanes to develop.  In this hurricane activity students research atmospheric trends that affect hurricanes and create a summary.

A set of 27 slides systematically shows how weathering, erosion, and deposition contribute to soil formation. Both chemical and mechanical weathering are described, as are resulting soil layers and properties. There is no longer any need...

Young meteorologists explore different aspects of the weather while learning about measurement devices. They build instruments and then set up a weather station outside and measure temperature, humidity, air pressure, wind speed, and...

Craft some neat refrigerator magnets while studying ocean animals with a lesson about the anatomy of a fish. After kids learn about the different parts and shapes of fish, they use modeling compound to design their own fish.

Pupils interpret maps and graph data related to volcanic ash. Then they analyze the importance of wind speed and the dangers of the ash to both life, air temperature, and technology. 

Students examine the issues surrounding air pollution. They discover how it affects peoples health and the government's regulations. They complete a word search activity to practice the vocabulary.
