Students discover simple gas laws by observing an egg sucked into an Erlenmeyer flask. When the flask is warmed, the egg is placed atop it. when both are placed in ice water, the egg slips into the flask. The procedure is then reversed....

Sixth graders observe with a microscope such simple crystals as salt, sugar, cream of tartar, and other chemicals which are listed in detail. They observe the crystalline structure and make comparisons, culminating in the creation of...

Students discover how molecules are in constant motion. Through a simple experiment of water containing food coloring, they observe the drops of coloring move even though the water is still. Role-playing as molecules, students stand up...

Students observe an experiment of freezing point depression using club soda. Through observation, they note that the carbon dioxide molecules disrupt the capacity of the water molecules to solidify. Precautions must be taken to assure...

Repetition, repetition, repetition. Get your class to efficiently repeat a section of code over and over again by introducing looping. Class members learn looping to quickly recreate objects they want to appear more than once in their...

A simple, yet effective lesson on dental health is here for your young learners. In groups, your class will place eggs in cups that contain a variety of liquids and observe what happens to the color of the egg. They brush the egg with a...

Take a load off! Introduce junior engineers to the effects of load on structural design with an easy-to-use interactive. Individuals apply one of many load options, examine its effects, then learn about the safeguards employed during...

Students explore how Maglev trains work. In this technology instructional activity, students discuss the pros and cons of Maglev compared to conventional trains. They build a simple Maglev train model.

Students explore static electricity using the Van de Graaff generator. In this physics lesson, students construct their own Van de Graaff using simple materials. They explain how charges accumulate on this device.

Students use the scientific method to conduct an experiment to test how a ball bounces. In this inquiry-based physical science and scientific method instructional activity, students drop a ball from specified heights and record the...

Students explore the active layer above permafrost and investigate various factors on the insulation value of the active layer.  In this energy transfer lesson, students conduct and experiment to determine the effects of snow cover,...

Students observe seeds growth and examine the different parts of the seedling. In this biology activity, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...

Students conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.

Young scholars perform an experiment with different types of bird eggs to determine what factors make them strong and able to stay on a cliff without rolling off.

Students observe a demonstration on the role of thermal conductivity in heat transfer.  For this thermal conductivity lesson, students design and conduct an experiment to compare the thermal conductivity of four substances....

Students study what an electric generator does and its history.  In this energy instructional activity students complete several experiments including building their own electric generator.

Students investigate the monarch's searching behavior and ability to find food. They determine whether or not a caterpillar can find food in a simple Y-shaped maze. They record and graph or chart the data from several attempts using...

Students use a chart of the six simple machines and become aware of how the machines improve our ability to meet the following needs: shelter, food, water, and transportation. Students use model cars to experiment with force. They divide...

Students explore Earth science by creating a scale model in class. In this shadow lesson, students research the impact the sun has on Earth shadows and complete a space science worksheet. Students create models of the Sun and Earth and...

Young scholars conduct a series of experiments on magnetic levitation. In this physics lesson, students discover how Maglev trains operate. They explain how magnetism make even simple objects levitate.

Students conduct a series of experiments on electromagnets. For this physics lesson, students build their own electromagnet and explain how it works. They determine the factors that affect its strength.
