Explore the behavior of light with different materials. Collaborative groups determine whether certain materials absorb, reflect, diffract, or transmit light waves. They then measure the angle of incidence and angle of reflection.

Which travels faster, light or sound? Scholars work in groups to simulate the ability for waves to travel through solids, liquids, gases, and through a vacuum. Then, they learn about the properties of a mystery wave and must determine...

Kindle knowledge of how light travels by using this activity in your physical science curriculum. By setting up a candle flame or flashlight bulb and viewing it through a slit, observers of light see evidence of its wave characteristic....

Learning about waves can have its ups and downs, but a demo-packed tool kit has the class "standing" for more! Learners gain experience with several different wave types, organizing observations and data, and wave...

Take a stretch, but don't wave goodbye. An interesting resource provides everything needed to present an introductory lesson plan on waves. Teachers present a PowerPoint defining the types of waves and their characteristics. Pupils use a...

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...

Did you realize the visible light spectrum is less than three percent of the electromagnetic spectrum? A hands-onlesson includes five activities and experiments for scholars to explore and discover many advanced science concepts. They...

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...

I bet I can cross the room without having the lights come on. Class members set up an experiment in which they try to determine what materials will mask motion detected by a sensor. Groups predict how materials will interact with...

Introduce teams to quantum dot solutions with an activity that has them expose solutions to a blacklight, observe the colors, and take measurements. Groups graph the data and analyze the dependence between particle size and...

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.

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...
