Columns have been used throughout the world because they are good load-bearing structures. Learners with visual impairments conduct an experiment to work through the design process as well as to understand this engineering phenomenon....

An average home produces twice as many emissions as an average car. Teach your class how to reduce energy consumption by replacing standard incandescent light bulbs with compact fluorescent light bulbs. Perform an experiment to compare...

Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period. 

Sixth graders investigate the various types of pollutants found in water and ways to help prevent water pollution. Through a hands-on experiment, students create samples of polluted water by mixing water with vegetable oil, dirt,...

Bothered by a wobbly table? Learn how to fix this problem using concepts of slope and continuity. Pupils first consider the problem in two dimensions and then progress to three dimensions. The solution is really quite simple.

How many ways can you arrange two six-hole Legos? Scholars practice their understanding of combinations as they investigate this question. As they create a plan, they develop a specific definition of a combination.  

So you built a magnetometer, now what? High school scientists use their magnetometer made in a previous lesson to map the union of magnetic fields of dipole magnets. They experiment with different alignments and draw conclusions about...

How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

How long do fresh foods last in space at the International Space Station? Which foods perish quicker than others? How can astronauts preserve their foods to make them last longer in space? Young scientists test the rates at which...

How did ancient peoples determine the height of really tall objects? Young scientists and mathematicians explore the concept of using shadows to measure height in a hands-on experiment. Paired pupils measure shadows, then calculate the...

Spring has sprung! Young physicists explore the properties of springs with a simple simulator. Users control the initial position of the spring, then observe the potential, kinetic, and thermal energies in the system.

Can your scholars solve the mystery of why salts dissolve? A virtual workbench allows them to experiment with temperature and solubility with no solution prep and no post-lab clean up! Users determine the solubility of a variety of...

Slow the spread of disease by slowing disease carriers in their tracks. Learners explore just how they might accomplish this as they experiment with the life cycle of a mosquito under different conditions. Scholars design and conduct...

Turning white light into colors only takes a little scientific know how! Young scholars create their own spectroscope in a hands-on activity exploring the properties of light. Using a diffraction grating, they discover how white light...

There are many factors that affect how fast the glaciers are melting. A lab investigation has learners examine how the surrounding water affect the rate glaciers melt. They collect data from two samples of ice to determine how quickly...

Make pathogens and the body's defense systems come alive for young biologists in a hands-on activity. Investigators model the skin's protection against infection by observing and comparing changes in a punctured tomato and an intact...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Not all linear functions are linear transformations — show your class the difference. The first lesson plan in a unit on linear transformations and complex numbers that spans 32 segments introduces the concept of linear transformations...

Take any number, multiply it by five, and then divide by five. Did you end up with the original number? In the same vein as the previous lesson, pupils discover the relationship between multiplication and division. They develop the...

Students hypothesize the content of unscripted moments and responses, search for evidence in the actual text to support their hypothesis, and explore how this hypothesis would affect characterization. Groups perform their scenes and...

Students perform experiments to determine the nutritional needs and physical space requirements for slime mold to survive. After formulating hypotheses, they seal the petri dishes and set up the experiment along with two controls. ...

Students describe science experience with appropriate attributes, units, and tools. They formulate inquiry question associated with the science experiences and curricular concepts from observations through class brainstorming. Pupils...

Students work together in groups to test light and how it reflects at different angles. They create their own hypothesis and answer questions given to them by their teacher. They complete the experiment at home and test if it changes the...

Learners research the effects of day-to-day weather on animal migrations, plant growth and other seasonal events. They consult maps, observe and record local conditions, keep journals and use their collected data check hypotheses.
