Intergalactic Interview
Students will practice their interview skills by pitching an ordinary Earth item to a panel of alien investors. Groups will take turns acting as both the design team and the panel as they build skills in giving and receiving feedback.
Lesson Plan
On Your Mark, Get Set, Roll
Students will explore how to create triggers by building a device that releases a ball when activated. Their design will need to include a trigger that can be activated from three or more feet away from the device.
Lesson Plan

Shipwreck Shelters
Work in teams to build structures that can withstand a natural hazard. Visit three “islands” (stations) and build a structure with only two or three materials.
Lesson Plan
Wind Maze
Students will explore the elements by designing a wind maze, a device that can direct the wind along a specific path.
Lesson Plan
Engineering Journals
Practice writing and documentation skills, whether in-person or virtual, with this journaling lesson.
Lesson Plan

Count the Seconds
Design a device that can track a specific amount of time and indicate when that time has passed with a sound or visual signal.
Lesson Plan
Engineering Journals
Practice writing and documentation skills, whether in-person or virtual, with this journaling lesson.

Exploring Chain Reactions
Explore concepts around simple machines and energy transfer by building components for chain reactions. With additional time and materials, refine designs into a connected chain reaction.
Educator Guide
Activity Guide

Aim High!
In this lesson, learners use stomp launchers to test launch angles and trajectories. Learners will track data collected by their team and use it to determine the optimal launch angle and height to get their rockets through a suspended target.
Lesson Plan
Brainstorming
In this method-based lesson, learners will work in teams to brainstorm and conceptualize a device
Lesson Plan
Just Dropping In
In this engineering-based lesson, learners design and build a device that will control the motion of a dropped ball.
Lesson Plan
You Do the Math
In this math-based lesson, learners will explore ways to calculate volume in regular objects and practice how to measure and calculate the volume of irregular/novel/real world objects.
Lesson Plan

Hover Design Challenge
During this engineering based lesson, students build, test and modify hovering devices in a wind tunnel to expand knowledge of design and aerodynamics.
Lesson Plan
Investigating Lift
During this science focused lesson, students explore the force of lift in a hovercraft and then create a labelled drawing to explain the forces involved in creating a working hovercraft.
Lesson Plan
Solve the Fall
During this engineering-based lesson, learners design and build a device that can survive a drop in order to deliver emergency supplies.
Lesson Plan
The Math Behind Circuits
In this math-based lesson, students build and explore different types of circuits and make calculations to gain practical skills in building, visualizing and understanding circuits.
Lesson Plan
Weight Distribution and Flight
During this ELA focused lesson, students conduct weight distribution experiments with paper airplanes in order to get information to share in a short presentation.
Lesson Plan

Lesson 1: Escape the Lava
Can you esign a device to help “Justin Case” escape lava by using items in your backpack?
Lesson Plan
Lesson 2: Mayday on Mars
Engineers often run into technical issues with their devices and engineering solutions can be helpful in these emergency situations. Can you build a device to help engineers move their device to a specific target without using any powered sources?
Lesson Plan
Lesson 3: Save the Hiker
Can you build a device that will deliver life-saving treatment to someone in a hazardous situation?
Lesson Plan
Lesson 4: Energy Madness
How can we design a machine that will deliver a remote control to an immobile friend?
Lesson Plan

Lesson 1: Animal Rescue
Scientists often need to gather information in order to form a deeper understanding of the problem. Can your team gather scientific evidence to help inform the design of a device that will help move endangered animals from one protected area to another?
Lesson Plan
Lesson 2: Traverse the Terrain
How can you use the coordinate plane to guide a vehicle through uncharted terrain on Mars?
Lesson Plan
Lesson 3: Go Rover Go!
How can we use the concepts of potential and kinetic energy to power a rover on a distant planet?
Lesson Plan
Lesson 4: Bridging the Gap
Can your team build the appropriate bridge to fit the needs of various terrains?
Lesson Plan

Lesson 1: Ant-Man Saves the Day
Build Ant-Man a flying device to transport him safely to fight crime!
Lesson Plan
Lesson 2: Lighter than Air
Scientists often need to gather information in order to form solutions to problems. Can you design an aircraft to help scientists gather information in areas of the world that can only be observed from above?
Lesson Plan
Lesson 3: Engineering Takes Flight
How can we design an aircraft that can deliver much needed medical supplies to a disaster area located on an island?
Lesson Plan
Lesson 4: Hoop Glider Design Challenge
How does changing the size of the glider’s hoops affect flight characteristics?
Lesson Plan
Lesson 5: Launch It!
How can you design a launch system to optimize distance and accuracy?
Lesson Plan

Lesson 1: Modeling the Earth--Motion Mock-Ups
What are earthquakes and what causes them?
Lesson Plan
Lesson 2: Building Basics
What structural materials and shapes best withstand an earthquake?
Lesson Plan
Lesson 3: Seismic Solutions
What makes a building safer during an earthquake? How does the location of load affect the earthquake safety of a building?
Lesson Plan
Lesson 4: Building Big
Will a scaled up version of our building perform the same way in an earthquake? How can we design a building to withstand the forces of liquefaction during an earthquake?
Lesson Plan
Lesson 5: Skilled Scaling
How do engineers communicate building designs so that the building is constructed safely and to exact specifications?
