Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...

The concepts involved with static electricity are typically taught in upper elementary physical science units. The lab described in this resource has pupils examine the behavior of small pieces of paper and a balloon when a charged piece...

Practice electric vocabulary using multiple methods. Learners begin by watching a video that explains vocabulary related to electric currents. They match vocabulary cards to practice and then create an electric circuit. Using the...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine...

Objects are larger (or smaller) than they appear! Scholars use a laboratory investigation to explore the difference between resolution and magnification. The activity allows them to calculate the size of the field of view of their light...

What exactly is a dirt baby, you might ask. Look over the plan to find out! All of the materials and procedures necessary for creating a dirt baby, such as grass seeds, dirt, and nylon stockings, are listed, along with ideas for...

Though an alternative method is suggested, the best way to carry out this investigation is with the use of a computer-interfaced motion detector. Physics fanatics hang a mass on the end of a spring and analyze its motion verbally,...

During an inquiry-based lesson, scholars decide which variable to test and then design an experiment to determine the needs of producers. After two weeks, they complete a full analysis and research paper.

In May of 1981, the Winter Park Sinkhole in Florida first appeared and is now referred to as Lake Rose. Scholars learn about the causes of sinkholes through an inquiry project. Then, they analyze recent data and draw conclusions to...

It is always a rush to drop objects from great heights, and with this physics experiment, class members will not be disappointed! They drop a single coffee filter from a balcony or table top, record the time it takes to reach the ground,...

Computer-interfaced motion detectors are required to carry out this inquiry. It is a new twist on exploring motion with plunger carts: they are set back-to-back and then propelled away from each other. Their velocities are measured, and...

Don't let the term, "slotted wood board" detract you from the value of this experiment. Class members tie a string to a cart and, with even horizontal force, drag it up an inclined plane. The objective is to compare the work done with...

Build a spectrometer to analyze properties of light. Scholars examine the spectrum from CDs and DVDs from two different light sources. Using the spectrum, they work to identify different elements.

Carbon dioxide is a very important gas; it is present in the air, used in cooking, and supports plant and animal life. Scholars investigate the properties of carbon dioxide with three different activities. They experience a color change,...

There's nothing better than a cool breeze blowing in from the ocean. Scholars explore how water affects change in temperature using a hands-on experiment on climate. They use measurement tools to compare the continental and oceanic...
