Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...

In this science worksheet, students find the words that describe the properties of waves and the answers are found by clicking the link at the bottom of the page.

In this light waves worksheet, students complete 7 short answer questions where they analyze and record findings about the properties of light waves.

Students manipulate a model of a wave in order to solve the wave equation in 1 dimension. By using a model of a wave on a string the student is able to change the tension, length, and mass of the string as well as fix either end of the...

Section 9 of the 12 linked Saxon Math sections introduces the young algebrist to graphing periodic functions, creating graphs from quadratic roots, working with inequalities, and rational equations. Common among all the lessons is the...

Since light travels faster than sound, some people may appear bright until you hear them speak. The presentation covers what sound is, how fast it travels in various mediums, properties of sound, hearing, and the parts of the human...

Students design and construct a listening device that will allow them to listen to the sound generated by specific object inside a box.

In this algebra instructional activity, 11th graders apply the 3 properties of logarithms to solve equations by expanding or condensing them. There are 4 problems to solve.

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.

Students discuss the light spectrum and light waves as well as how the properties of light and color have contributed to important discoveries about properties of the universe. They research the term redshift and the redshift phenomenon...

Students investigate the refraction properties of gelatin to calculate its index of refraction. They discover that as the light travels through the gelatin, its speed and wavelength also change. Students find th indes of refraction of an...

Investigate ellipses through the lens of medical applications. Pupils use a medical scenario to determine the equation of an ellipse. By using the interactive, learners determine the foci and major and minor axes of the ellipse that...

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...

A phenomenal lesson on sound is here for your third graders! In it, learners engage in hands-on activities, watch video, take part in Internet activities, and complete tasks in cooperative groups in order to explore the world of sound...

In this light waves worksheet, students will measure the wavelength of different light waves and then calculate its frequency. This worksheet has 9 short answer questions and 10 fill in the blank questions.

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...

Learners 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...

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...

Young scholars discuss different ways engineers use light. In this engineering lesson, students are introduced to the properties of light and the way light is used. They view a demonstration of light waves using a slinky, and practice...

Students explore light. In this properties of light instructional activity, students define the terms refract, reflect, and diffract after listening to the teacher's description. Students listen to the book Light Magic and observe a...

Students identify different wave types and their characteristics.  In this wave lesson students complete activities by activating tuning forks and interpreting data. 

Students experiment with objects of different densities. For this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar...

Aspiring meteorologists make themselves a tool for reviewing the characteristics of each layer of the atmosphere. The procedure for this little project divides the paper into five sections, but many earth science teachers opt for the...

Students examine how light waves travel. In this properties of light lesson, students observe how light travels in water, how light is reflected and refracted, and how light is pure energy.
