Did you get to play with electric currents or were you grounded? An electrifying simulation shows how building up a charge of electricity creates a static shock once grounded. Pupils rub John's foot across the carpet and view the buildup...

Henry the Hand leads youngsters on an exciting adventure through coloring worksheets, word puzzles, and comic strips on everything they need to know about preventing the spread of germs by washing your hands.

How does the depth of an ocean affect the speed of a tsunami's waves? Use Jell-o, graham crackers, and marshmallows to model the effects of an underwater earthquake and its resulting tsunami. The lesson includes hands-on activities,...

There's more to that glowing ball of light in sky than most children realize. From the overall structure of the solar system, to the changing of the seasons, these hands-on lessons open the eyes of young scientists to...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

Your youngsters become cheetahs in search of food, water, shelter, and space in a fun physical game that does a fantastic job of representing fluctuating species population based on resources available over years. 

Different varieties of Christmas trees provide an interesting way to combine social studies, science, math, and technology. Class members not only research the history of the Christmas tree holiday tradition, they compare and...

It's frog party time! With frog banners, frog juice, and a triangle hunt, your garden party is sure to be both entertaining and educational. The lesson plan connects geometry, earth science, and delicious snacks to teach kids about...

How can you tell what an owl has eaten? Study the food chain and flow of energy in an ecosystem by dissecting an owl pellet and noting the bones found inside. Additionally, the lesson includes a game about consumers and producers with a...

Three, two, one, blast off to a better understanding of force and motion with this exciting science lesson! Beginning with a discussion about rockets and gravity, young scientists go on to complete a series of worksheets about net...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

Upcoming chemists use chemical reactions to determine relative pH in two different acids. This is a terrific lesson for middle schoolers that can stand alone as a practice in precision and lab skills, or as part of the unit on chemical...

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...

If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

By both demonstration and hands-on investigation, physical science fanatics come to know that some materials react when they come together. Adding vinegar to both baking soda and to baking powder, the difference between the two is clear....

Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...
