Introduce your earth science enthusiasts to the earth's energy budget. Teach them using an informative set of slides that include illuminating lecturer's notes, relevant vocabulary, embedded animations, colorful satellite maps, and a...

Marshall Brain uses a sponge, rope, and other common household items to display the workings of the digestive system. This resource would definitely hold the attention of a squirrely junior high class!

Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...

Middle school science stars observe and record data on the solar radiation reflected off or transmitted through various materials. They predict properties for various materials, and test their predictions by touch. This instructional...

Heat-sensitive liquid crystal sheets are available in a variety of sizes and temperature ranges. Purchase a class set of hand-held sheets and color half of each with a silver permanent marking pen. Learners of light can hold them under a...

Nutritionist Radhia Gleis explains what metabolism is and how to assess it. Food is processed and used by the body producing waste in the end. The steps of the digestive system are explained from its beginning in the mouth to its end in...

As Natalie describes in this video, nutrition is about more than just having a healthy diet. Your body's absorption, digestion, and elimination is key in your overall health. The function of enzymes is clearly explained along with the...

Study the properties of soil and water absorption with a science activity. Based on a paragraph with background knowledge on sandy soil, silt, and clay soil, third graders choose which illustration represents a bottle full of sandy soil....

Advanced lab apprentices prepare zinc and copper solutions to which they will compare the same minerals from a multivitamin. Using absorption spectroscopy, they analyze the contents of the multivitamin for concentration. This lab can be...

Slides and slides of emission spectra bring this topic to light for your physics class! Exited electrons returning to lower energy levels is offered as the cause of emission spectra. In summary, viewers learn that we can determine the...

Pupils record temperatures at different locations around campus. They examine the results and draw conclusions about how materials and colors affect the amount of heat produced. They also analyze Los Angeles' temperature records over a...

Third graders explore the capillary action of plants. They discover what makes paper "grow" when water is dropped on it. Pupils observe how paper reacts as it absorbs water. Students use a variety of saturate solutions to grow crystals,...

Quite a detailed and advanced look at the transport mechanisms of a plant. The absorption and control of sugar and water concentration are explained and will help an understanding of homeostasis concepts and organ specialization.

Take your class on a journey through the digestive track with this resource. The physical and chemical processes of digestion are detailed, along with the names of various structures and substances involved, but the processes of the...

Elementary school physical scientists explore kinetic mechanical energy by dropping a golf ball on different surfaces. They discuss how human made materials might react to light differently from nature made materials. This lesson plan...

Here is a physical science activity where pupils place thermometers inside of a white and a black paper pocket and place them under a lamp. They record and compare the temperature increase over a ten-minute period. Have your class...

Students examine the properties of light and the behavior of light during interference.  In this electromagnetics lesson students explain behaviors of light.

Students explain how laser security systems work.  In this security system design lesson students create a presentation of their system that they designed. 

Ninth graders conduct an experiment which demonstrates the absorption and reflection of sunlight by measuring the heat flow through various window coverings. They predict the relative amount of the sun's heat. Students draw conclusions...

Students experiment with sunlight and temperature. They study the definition of albedo, or the percentage of incoming sunlight that is reflected, rather than absorbed.

Use this great overview to give information on all aspects of nutrition. By working their way through this PowerPoint, students review a lot of information about the digestive process.  Students read many facts on a number of detailed...

Students examine the techniques that may be used to reduce carbon dioxide in the atmosphere.  In this pollution lesson students simulate oceanic sequestration using chemistry.

Young scholars examine how to apply conservation of energy and properties of matter to a spectroscope.  In this energy lesson students build their own spectroscope and observe three kinds of spectra.

Young scholars participate in paper marbling. In this paper art lesson, students use shaving cream and paint to create unique patterns on paper. Young scholars mix shaving cream and paint together then lay paper down in the mix. The...
