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...

Students participate in a problem-solving activity, that includes Internet research, about how energies such as currents, waves, tides, etc. affect the ocean.

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 compare and contrast the properties of salt water in the oceans/seas and freshwater elsewhere on the planet. They also analyze mixing caused by currents in the ocean, including the effects of warm and cold water as well as with...

Tenth graders should know how sound is produced and state some properties of sound.

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...

Bring the ocean floor to life! Earth science scholars discover the process of deep sea mapping in the third installment in a series of five lessons about ocean exploration. The teacher's guide includes helpful resources, worksheets, and...

Ninth graders are introduced to the components of compressional and transverse. They practice answering speed problems involving different mediums that waves travel trhough and then review the wave PowerPoint. They then visit physics...

In this science:  water quiz worksheet, students answer twenty questions, not interactively about the properties of water, then scroll down to check their answers.

Students make predictions about how sound is formed. They view and discuss a video that explores sound formation and attempt to identify the origin of different sounds.

Middle schoolers demonstrate sound waves and make changes in the waves resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.

Students explain the wave properties of light.

Light is such a fascinating subject. This lesson does a great job of illuminating the mysteries of light for your young scientists. A series of demonstrations which are explained in the plan should help your charges to understand how...

Students study hearing and are able to differentiate between different sound waves.  In this sound wave activity students develop a cause and effect model that shows the parts of the ear. 

Students explore constructive interference and destructive interference. In this light travel lesson, students follow procedures to discover how light waves travel and experience interference.

Young scholars are able to describe what happens to light when it strikes different materials. They describe the law of reflection. Students are able to explain why a mirror froms a virtual image. They are able to describe diffuse...

Young scholars study hummingbirds and how they use Newton's law.  In this motion lesson students complete several activities and view videos of hummingbirds. 

In this wave properties worksheet, students will experiment to see how the sound made by vibrating a ruler is affected by the length of the part that is vibrating. Then students will answer 5 questions based on the results of the...

Students engage in a lesson to investigate some of the properties of sound. They create sounds and listen to the vibrations that are made while listing all the sounds that are heard. This is done while the eyes are closed to strengthen...

For this algebra worksheet, 11th graders graph parabolas and figure out the major axis and minor axis of the graph. They also find the focus. There are 4 problems on this worksheet.

Students design an experiment to analyze the timbre of different instruments. In this physics lesson, students analyze the missing quality in sound. They discuss their results in class.

Students determine that waves carry energy and information from one place to another. They determine that wavelength, frequency and wave speed are related and describe that sound is a longitudinal wave whose speed depends on the...

Students research the life of Thomas Edison. In this Thomas Edison lesson, students explore major life events of Thomas Edison. Students investigate the inventions of Thomas Edison.  Students discover how various fields of study...

Fifth graders investigate the relation between vibrations and pitch. They observe and discuss an experiment involving a bicycle and a piece of cardboard in the spokes, listen to a comb with cardboard, and listen to various sounds and...
