If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Students distinguish waves from matter, differentiate between transverse and longitudinal waves, use sine curves as representations of transverse waves, label characteristic properties of waves, diagram transverse waves having specific...

A two-part lesson asks young scientists to research the contributions of African American scientists at Bell Laboratories. After presenting their findings, class members watch two demonstrations that introduce them to total internal...

Gummy bears are tasty, but did you know they are also used to determine color and light properties? Use the activity as a way to demonstrate light absorption, light reflection, and refraction with high schooler....

Why can we see our reflection in a window but not a brick wall? Young physicists learn the Law of Reflection and various light properties that help them answer this and other questions about reflection. Use the PowerPoint to introduce...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

Pair physical science learners up, and have one describe a transverse wave while the other blindly attempts to draw it. Then reveal an actual diagram and explain the different parts of the wave: crest, trough, wavelength. Though most of...

Explore physical science by participating in a visual spectrum experiments. Budding scientists identify the colors in the color spectrum and view the colors in class by utilizing cellophane, flash lights, and other arts and crafts...

Learners explore the different properties of waves. In this physics lesson, students differentiate mechanical and electromagnetic waves. They explore each lab station and write their observation about the wave behavior they see.

Students compare and contrast electromagnetic and physical waves. In this wave lesson, students discover that all waves reflect, refract, and diffract energy. Students work in small groups to experiment with waves and evaluate the type...

After learning about P waves and S waves, fifth graders view the intensity of earthquakes by examining seismographs and images of earthquake damage. Young scientists then forecasting future quakes by analyzing data about...

Have your class engage in lessons on earthquakes. Learners explore the science behind earthquakes using interactive websites and video clips. Then, they review the layers and parts of the Earth before delving into the causes of...

Learners identify the different parts of a wave. In this physics lesson, students explain how animals communicate using sound waves. They discuss the effect of Navy's sonar on dolphins and whales.

Students explore earthquakes and seismic waves. They investigate how energy is released in the subsurface to create seismic waves. Students explore the inner workings of a seismograph and how they are used to determine the location of an...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Students explore the properties of electricity. This lab shows students the need for a circuit in order to have a flow of electricity. It demonstrates Ohm's law, which relates voltage, current, and resistance.

Students are introduced to gases. In this science lesson plan, students demonstrate that gases are a state of matter, generate a number of gases, discover some properties of gases, compare some of the properties of different gases, and...

For this science worksheet, students are guided through a computer simulation of a frog dissection in which the heart is kept beating. Students test each of seven solutions by introducing it into the simulated heart. Students collect...

Students explore and model the characteristics of the ocean floor and near shore environments through in-class demonstrations, laboratory activities, and internet research. They use classroom materials to research the characteristics of...

Students explore tsunami through various hands-on activities. In this earth science lesson, students explain how they are formed. They create tsunami and earthquake models in the lab to observe how they are generated.

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

Learners examine how to conduct simple investigations and use simple equipment to gather data.  In this magnet lesson students decide what types of objects are attracted to magnets. 

Students determine the spring constant by conducting an investigation. In this physics lesson, students collect data and create a graph of force vs. displacement. They compare the results of two different methods to find spring constant.

Students investigate the Richter scale and seismology in a teacher-led lab in which they are introduced to the concept of seismic waves and epicenter location. They further investigate the inner workings of a seismograph and practice...
