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...

Can you build a device that will deliver life-saving treatment to someone in a hazardous situation? During this lesson plan, students will learn how energy is converted and transferred between objects. Working in groups and through the...

During this math-focused unit, young scholars will create a device that is used to harvest fruit from a tree. They will then look at failure points in order to iterate their design. Finally, students will describe their device as a...

In this 21-day unit, students are introduced to the anchoring phenomenon-a flameless heater in a Meal, Ready-to-Eat (MRE) that provides hot food to people by just adding water. They complete investigations to collect evidence to support...

In this week's Afterschool Adventure, children will practice and explore strategies for solving addition and subtraction problems, such as using counters and rulers, performing mental math, and drawing pictures. As children encounter...

Children will learn about and explore measurement to successfully design a dog house for his or her cutout paper dog. Each section of this weeklong adventure is introduced by a video clip or online game that encourages children to...

This lesson introduces learners to the art of designing an airplane through paper airplane constructions. The goal is that students will learn important aircraft design considerations and how engineers must iterate their designs to...

Practice using iteration in computer programs to repeat code until a boolean expression is true for programs written in the AP CSP pseudocode, in this set of practice questions designed for AP Computer Science Principles students.

Practice iteration (repeating code multiple times with loops) for programs written in the AP CSP pseudocode, in this set of free practice questions designed for AP Computer Science Principles students.

A good beginner's site for fractals - the language is straightforward and requires only minimal experience to be able to understand the topic. (Note: When clicking on links on archived site, they may pause and appear not to be found...

Here's an example of "What a 2 Dimensional Julia Set will look like using modern computers with their sophisticated graphical displays." Gaston Julia published his theories long before computers and as the site's author remarks, "What a...
