Students follow the steps of the engineering design process as they design and construct balloons for aerial surveillance. After their first attempts to create balloons, they are given the associated Estimating Buoyancy lesson to learn about volume, buoyancy and density to help them iterate more successful balloon designs.Applying their newfound knowledge, the young engineers build and test balloons that fly carrying small flip cameras that capture aerial images of their school. Students use the aerial footage to draw maps and estimate areas.

Students explore static electricity by rubbing a simulated balloon on a sweater. As they view the charges in the sweater, balloon, and adjacent wall, they gain an understanding of charge transfer. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments.

The purpose of this activity is to bring together the students' knowledge of engineering and airplanes and the creation of a glider model to determine how each modification affects the flight. The students will use a design procedure whereby one variable is changed and all the others are kept constant.

Students groups use balsa wood and glue to build their own towers using some of the techniques they learned from the associated lesson. While general guidelines are provided, give students freedom with their designs and encourage them to implement what they have learned about structural engineering. The winning team design is the tower with the highest strength-to-weight ratio.

Diphtheria has broken out in Nome, Alaska. Teams of sled dogs carry medicine 800 miles over snow and ice to prevent an epidemic. Everyone was brave but one dog, Balto, made the difference between failure and success.

Bamboo Learning is the leader in voice powered education, having won three national awards for voice-based e-learning tools. Our Alexa skills, Bamboo® Books, Bamboo® Luminaries, Bamboo® Math, Bamboo® Music, and Highlights Storybooks from Bamboo, get more challenging as students master different levels. Bamboo skills also track progress & award badges. Bamboo Grove is a web-based parent dashboard for parents to follow their children’s progress in Bamboo Learning’s Alexa skills.

The purpose of this task is to provide students with a multi-step problem involving volume and to give them a chance to discuss the difference between exact calculations and their meaning in a context.

The purpose of this task is to provide students with a concrete situation they can model by dividing a whole number by a unit fraction.

A way to take inventory of band instruments using QR Codes. This website describes the process.

Explore the origin of energy bands in crystals of atoms. The structure of these bands determines how materials conduct electricity.

This real world task requires students to answer questions about equations for calculating compound interest.

This task asks students to use similarity to solve a problem in a context that will be familiar to many, though most students are accustomed to using intuition rather than geometric reasoning to set up the shot.
