There are a billion reasons to use the resource! Well, not quite. A demonstration using food color and water shows scholars the meaning of nano. An iterative process results in diluting the concentration of food coloring by one tenth...

Using the resource is probably the most efficient way to learn about efficiency. The 18th installment of a 25-part Energy Systems and Solutions unit has pupils investigate energy efficiency through discussions and associated activities....

Take the periodic table into the digital age with QR codes that take the scanner to an audio recording about each element from the Royal Society of Chemistry. Enlarge the image, then use a smartphone or tablet to scan the code for an...

What's the least number of colors needed to color a U.S. map? The lesson begins by having pupils view a video clip on continuous and discrete phenomenon, then launches into an activity reminiscent of Zeno's paradox. A separate video...

Water is a powerful force; harness it through watermills. The task at hand is to create a simple watermill that functions in flowing water for at least three minutes. Scholars work together in teams to design and construct such a...

There are patterns in nearly everything — even earthquakes. Pairs research current earthquakes to see if there are any patterns. They determine the mean, median, and mode of the earthquake data, along with the maximum and...

Introduce your class to storage tank failures caused by major storms with an activity that looks at how the concepts of Archimedes' Principle and Pascal's Law affect the storage tanks along the Houston Ship Channel. The background...

What's the best way to use a simple machine to solve a real-world problem? Scholars construct their own simple and complex machines to explore the concepts of work and force. They discuss examples of simple machines they have found in...

Turtles might be slow, but class will zoom by when your pupils build a program in which reptiles draw a grid. Using App Lab and JavaScript, class members build a program to find the most efficient way to draw an image of a...

It's time to slow your roll! Can your class create a track that allows a marble to roll as slowly as possible? Teams of science scholars collaborate to design, build, and test their tubes while learning about gravity and friction.

Let the good times roll as young thrill seekers build a roller coaster on school grounds. Future engineers design and build a roller coaster from flexible tubing. The roller coaster is for a marble, so there will be plenty of room to let...

Take foldables to all new heights. Pupils build and fly different types of paper airplanes in the 14th portion of a 22-part unit on aviation. Groups collect data on distance and flight time for each plane and compare the data from the...

Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor,...

Introduce your class to air masses and how they affect the weather with a lesson that focuses on the differences between high and low air pressure systems. The class explores actual weather data using archived weather data.

An MRI uses both a magnetic and electricity, so how do the two interact with each other? Class members observe the effects on a charged particle when it is subject to both an electrical and magnetic field. The teacher background...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Study heart health and math in one activity. After measuring their resting heart rates by finding the pulse in their wrists, learners build a stethoscope to listen to their heart rate, and note the differences between the two methods.

Through the journey of four stories of immigration, scholars complete graphic organizers and apply knowledge to create a visual representation of their findings on a large poster. Third and fourth readers write a letter to their...

As an introduction to using a network to determine the fewest number of nodes that meet a given condition, small groups work together to determine the fewest number of ice cream vans, and their locations, to be able to serve the people...

Binary graphing ... bit by bit. Pairs work together to develop a protocol in order to send the points of a graph. One partner sends the points and the other receives them and tries to recreate the graph. The pupils use the rubric to...

How well can you launch a ping-pong ball? Small groups design launchers that can launch a ping-pong ball 20 feet into a target. The teams follow the engineering design process as they develop a solution that meets the design...

Turn your pupils into engineers who are able to use scientific principals to design a ship. This long-term project expects pupils to understand concepts of density, buoyancy, displacement, and metacenter, and apply them to constructing a...

Explore capillary action from different perspectives. In the fourth installment of a nine-part series, scholars perform several experiments to observe capillary action. They look at the meniscus of water in a glass, observe capillary...

How do robots move? A presentation shows viewers the different types of configurations of that help robots move and lists the advantages and disadvantages of each of the configurations.
