Hull Engineering
Source Institutions
In this activity, learners explore how the hull shape impacts a ship's performance and stability.
Jam Jar Jet
Source Institutions
In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
Jump Into Design: Understanding the Design Process
Source Institutions
In this series of activities (page 5), students are introduced to the design process.
Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Clap Sensor: Build a Sound Sensor Using a Pico Cricket
Source Institutions
This activity requires a Pico Cricket (tiny computer). Learners work on designing and building a sound sensor out of household materials, like plastic wrap and cardboard.
The Awesome Game Race
Source Institutions
In this engineering activity, learners design their own board games.
Doghouse Design
Source Institutions
This activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.
High Tech Fashion
Source Institutions
In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.
Water Fountain
Source Institutions
In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.
Pipeline Challenge
Source Institutions
In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.
Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.
Robot Basketball
Source Institutions
In this activity, learners explore accuracy and precision.
Using Ohm's Law to Build a Voltage Divider
Source Institutions
In this activity, learners apply Ohm’s Law to construct voltage divider circuits. Learners discover how to read resistor codes and calculate resistor values.
A Question of Balance
Source Institutions
In this activity, learners explore how engineers use scales and measures when designing a manufacturing process to ensure that final products are uniform in weight or count.
No bones about it!
Source Institutions
This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.
Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.
New Boxes from Old
Source Institutions
Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.
Racing with the Sun: Creating a Solar Car
Source Institutions
Learners use engineering design principles to construct and test a fully solar-powered car. Solar car kits usually include a photovoltaic cell and motor; some include a chassis as well.
Wind Power: Creating a Wind Generator
Source Institutions
This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.
