Students conduct experiments to discover the various ratios of oil to popcorn kernels. They determine which amount of oil produced the most popped kernels.

Students investigate the best way to calculate the measurements of an area. In this geometry lesson, students relate a large circle to a cylinder and its measurements. They use PVC pipes to gain hands on experience as they calculate the...

Junior scientists work in groups to construct electromagnets. They experiment by varying number of wraps around the nail, the diameter of the nail, and the type of metal the nail is made of to see if any of these factors has an...

STEM scholars investigate sound attenuation by conducting an experiment in which they compare the farthest distance that they can hear a sound with and without ear protection.

Students examine the Dust Bowl and the effects of farming practices in the early 20th century. They read a handout, and conduct and discuss two experiments simulating soil erosion.

Students experiment with converting fuels to energy. They also must identify different types of fuels and ways to conserve energy.

Young scholars explore space science by conducting a sun experiment in class. In this time telling lesson, students discuss how the sun sits in our sky at exact times each day and how astronomy is based on our perspective of the solar...

Students explore the optimum angle for orienting a solar collector relative to the rays of incoming sunlight. They review equinoxes, solstices, and various locational ideas before students investigate using meters, light sources, and...

Students construct their own magnet and wire device. In this inquiry instructional activity, students investigate the factors affecting the strength of magnetic forces. They manipulate different variable to determine their effect.

Students explore how a circuit works and create a circuit to use energy from a battery to light a bulb. In this introduction to circuits instructional activity, the students study the parts of a circuit and have a class discussion of...

Young scholars watch a demonstration that introduces them to the idea that friction is a force that impedes motion when two surfaces are in contact. They work in groups to experiment with frictional force using a coffee cup on which they...

Learners build simple electromagnetic reed switch motors. In this physics lesson, students explain how it works. They cite real world applications of reed switches and relays.

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Fourth graders examine parallel and series ciruits. They experiment what happens if a bulb is removed from both a parallel and series circuit. They understand the differences between parallel and series ciruits,

Ninth graders observe the relationship between electrical charge and force.  In this electrical charge lesson students experiment and find the quantitative relationship between force and the center to center distance between objects.

Students measure the electric potential of 9 volt batteries using oscilloscopes. They draw a diagram of the front panel of the oscilloscope, conduct the experiment, and create a graph of voltage versus the number of batteries.

Students explore the motion of a toy bungee jumper using the scientific method. They view a video of a bungee jumper and discuss what can be measured about a bungee jump. Students discuss the scientific mehtod and how to design an...

Students experiment with electricity to understand lightning. For this lightning lesson, students show how static electricity causes lightning. Students discuss questions about their experiment and gather important facts. Students...

Students 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.
