Sometimes we all need a helping hand. Scholars get together to lend a hand in creating an assistive device that must be able to grab a hard-to-reach object. Now that's some help we could all use!

Make breaking a leg a less troublesome experience. Groups brainstorm designs for crutches that have devices that help carry items. They build prototypes of their devices to test out their designs.

How do engineers determine the most efficient highway designs? Introduce young scientists to the world of topology, the branch of mathematics that examines how things are connected. Teams use model highways to create the most...

Design a simple structure such as the gazebo. Work with your class to identify the six faces of a cube pattern and name other uses of patterns in industry. They draft, cut out, and assemble a cube pattern. They draw out and assemble two...

Let the sun shine as your young coders move the clouds across the sky while practicing animation coding skills in JavaScript. Younger learners may benefit from more guided help or a whole-class discussion before trying this coding...

The liquids did not mix — so what do density columns have to do with it? The seventh part in a series of nine provides the theoretical explanation of why density columns do not mix. The lesson covers the topics related to...

Reach out and grab something. Given the task of picking up objects at least two feet away, pupils design and build a grabber. The last activity in a series of five challenges requires learners to use information about fulcrums and levers.

Learners investigate the importance of community service by creating their own project ideas.  In this volunteering lesson, students research stories of Peace Corps Volunteers and how they were able to have a positive effect in...

Cancer patients need as much help as they can get. Future engineers design a system that delivers cancer medicine to the lungs but doesn't harm other organs. Using ferrofluids and iron particles, they test out their delivery systems.

Meet me in the tunnels. Scholars choose a tunnel entrance and mark it on their side of the cardboard. They describe the location to their partners and see if they can guess each other's locations. Punching a hole through the cardboard...

Newton's Laws get the rocket to work, but do they serve any other functions? A six-page resource classifies rockets by the type of propellant they use. It then describes applications of Newton's Laws of Motion, both in the...

You won't regret being stuck with this activity. By mixing a variety of household items, pupils create their own glue. They test the tensile strength of their glue and compare it to that of other adhesives.

Extremely large or extremely small numbers are difficult to comprehend. To help understand the massive scale of the solar system, learners complete two activities. First, they create a model to compares the size of the bodies in the...

In a simple but unique lesson, youngsters learn about the history of voting systems. They then collaborate in groups to develop a new honest and consistent voting method. A class-wide poll is taken, evaluating the designs of other...

The choice is simple: create a PowerPoint presentation, write a book, or invent a compound machine. Whichever project your young scientists choose, they will be engaged in creatively demonstrating their knowledge of simple...

An "H" is just three rectangles when you are trying to draw them on a computer screen. After watching the previous Intro to Drawing video this online programing activity guides young coders to draw the letter "H" on the screen. Help and...

Take a big bite out of the red tomato by practicing your use of the variables mouseX and mouseY in a JavaScript coding task. The activity will guide you step-by-step and will help young coders understand how to draw objects based on the...

Create a list of your favorite foods while you practice writing text in JavaScript. Use fill, textSize, and text functions. This is a quick activity that helps solidify basic skills. Expand with additional challenges...

Take your drafting and design projects on the go with with this mobile computer-aided design program. Allowing users to view, edit, and share their work with others, this is a great resource for developing the technical drawing...

How can you tell what someone is feeling when they aren't saying a word? Explore non-verbal communication with an activity based on Cynthia Breazeal's work with expressive robots. One learner puts a bag over his or her face and uses body...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

The second segment of a seven-part series reviews the challenge of determining whether gargling with salt water helps a sore throat. Individuals journal what they know about the challenge and what they are trying to figure out to...

Let the solar cells fight each other for supremacy! Given a functional solar tracker that moves toward light, groups copy the design to build their own devices. They use two sets of solar cells that have reverse polarization, so that the...

Those who build together learn together. Scholars work in groups on two teamwork-building activities that involve engineering design. They first construct the tallest tower they can using five sheets of paper and masking tape. Next, they...
