Support your young scientists' knowledge of logarithms with a quick video lesson. The instruction first presents the relationship between a base-10 logarithm and an exponential equation. It then demonstrates how to use a calculator to...

What kind of organisms are living in the stream? After an explanation on how to use a dichotomous key, groups of three to four use the keys to identify macroinvertebrates from a local freshwater stream. Using the the concept of...

Using a home-built hydrophone, pupils investigate how things sound in water. Learners listen to sounds created in air and then compare that to the same sound picked up by the hydrophone. Individuals compare the loudness and the pitch of...

Do some experimentation with reduction-oxidation! Stoichiometry superstars use a single-replacement reaction to study limiting reactant, theoretical yield, and the reactivity of metals through a lab activity. The teacher's guide includes...

The asteroid is getting closer and the question is whether the state of Alabraska is large enough for the shelter calculated in the previous activity. Teams determine the scale of their project and then use the scale on the map to...

Determine the power hog in the house. Pupils learn the difference between power and energy before participating in a hands-on activity. Using a power meter, pairs measure the actual power used for several household devices, estimate the...

Keep your hands on the wheel—at all times! Scholars learn why pilots use a flight computer through a high-flying demonstration. Making calculations for speed, distance, or time is automatic if you know how to use a flight computer. 

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

Do bigger sails mean that the sailboat goes faster? Middle and high schoolers compare sailboats, and learn that simply calculating sail area is not enough. A slideshow presentation demonstrates how to calculate the Sail...

Reduce the work it takes to plan a physics lesson on energy with the help of this instructional presentation. Beginning with clear explanations of kinetic and potential energy, this resource continues on to familiarize young...

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Young scientists use a worksheet to help them perform a lab on the decay of a radioactive element. The worksheet serves as both a task guide and a lab sheet for pairs of learners. This activity requires a calculator and has excellent...

Based on the rate of melting observed from 2003-2007 in Greenland, it would take less than 10 minutes to fill the Dallas Cowboys' Stadium. The 17th activity in a series of 21 has scholars use the ICESat data to understand the ice mass...

Your class will use a set scale to convert diameters of planets to the model size, the diagram given to expand on the number of planets drawn as concentric circles, and examine the scale that would be needed to fit the larger...

Provide a Hooke for a lesson on elasticity with an activity that has groups investigate a set of springs. They use a set procedure to collect data to calculate the spring constant for each spring using Hooke's Law. The groups...

You didn't know you'd find moles in chemistry class! Through the introduction of moles and molar volume at STP, classes see how to calculate moles using a given chemical equation. The presentation includes a short review of ions in...

Emerging engineers discover how important it is to conserve energy as fossil fuel supplies are being diminished. This is accomplished by working through a handout that explains energy requirements for heating a home during the winter....

What better way to learn how to use a microscope than building your own? A lab investigation has scholars use lenses from magnifying glasses and sheets of cork to design their own compound microscopes. They calculate focal length...
