Earth is 149,600,000 km, or 92,957,130.4 miles, from the sun. Young astronauts create an interactive model to learn the distances between planets. Nine groups, each representing a different planet, are spread around at class-calculated...

Young investigators conduct an experiment using the scientific method. They see how many drops of water fit on a coin; have them conduct several different trials. This involves making a hypothesis, looking at controls, and introducing...

Young scholars are introduced to a gas chromatography using a discovery-based approach. They are presented with a scenario/industrial application where their job is to verify that the company's mouthwash contains a specific percentage of...

What do your vital signs tell your doctor? An engaging hands-on lesson has your learners monitor their own lung capacity, blood pressure, and heart rate. They then connect the vital measures to the workings of the circulatory and...

You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

Are you looking for a good, solid instructional activity on sedimentary rocks? This one, produced by the Illinois State Museum, is just such a instructional activity. Middle schoolers identify common rocks and minerals by analyzing...

Who needs a barbecue grill to cook hot dogs when you have the amazing power of the sun at your disposal? Engage young scientists in learning about solar energy with this fun activity that turns a used Pringles can into a solar...

The evaporation of water and what happens to it as it travels through the water cycle are the focuses of this lesson plan. The evaporation of water seems like a "magical" process to people of all ages. This lesson plan takes away the...

Do polar opposites attract? After an introduction on the polarity of molecules, pupils are asked to design a self-assembling model using materials with different polarity. The challenge should motivate learners to develop a workable...

Given four suggested concepts, emerging electrical engineers research, design, and constuct a working device that willrespond to changes in the intesnisty or the direction of sunlight. This is a challenge for learners to rise to, as the...

It's a win-win situation: learn about enzymes and get clean clothes, too. Young scientists add enzymes to a dilution of laundry detergent. They apply them to stained fabrics to determine the effectiveness of the enzyme-filled detergents.

That's not what I said! My message did not arrive in the correct order! Introduce the concept of packets and the transmission control protocol used to send and receive information over the Internet. The class participates in an...

In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

Students evaluate the impact beetles have on plants. In groups, they select plants to expose to leaf-feeding beetles and place those beetles on the caged plants. They observe the beetles and discuss the insect and plant interaction...

Using a simple method, learners explore gravity, cohesion, and adhesion. They perform an experiment in which they determine how many drops of water can fit on a penny. Afterwards, they discuss their results.

Students explore the effects of velocity on an object when it collides with another object. They design and outfit a potato astronaut in a spacesuit to withstand the hazards of high velocity impacts from space debris and meteoroids.

Learners work with the scientific method; observation, hypothesis, and experimentation. They observe the effects of decay and the need of good oral hygiene during an experiment with an apple.

Students read about and discuss water and how it is used as a resource and how engineers use technology to preserve it. In this water lesson plan, students look at a picture of water treatment and tell what is wrong with the picture.

Students build tools to help track the weather. In this weather lesson, students follow directions to build a rain gauge, barometer and hair hygrometer.

Students define conservation, exploitation and preservation, identify legislation related to conservation and environmental issues, and identify leaders and organizations that were key to the conservation and environmental movements.

Pupils research the formation and life-span of hurricanes and, after analyzing statistics, try their hand at plotting and predicting the course a hurricane.

Students examine the theory of finding latitude and discuss the uses of an astrolabe, cross-staff and octant. They determine an Astronomical Table for their classroom.

Learners identify and describe the difference between the magnetic north pole and true north. They consider why sailors could not steer a straight course to the New World from the Old.

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...
