Maximum Mentos Fountain
A messy fountain is potentially an energy experiment in disguise. Groups investigate the variables in creating a fountain from soda and Mentos. The last activity in a six-part series on energy has the class observe the fountain in terms...
Teach Engineering
Exploring Energy: Energy Conversion
The energy is not really lost, it is just converted to a different form. Pupils learn about the conversion of energy in the fifth segment of an energy unit with six parts. Learners develop an understanding of the conservation of energy...
Teach Engineering
Airplane Tails and Wings: Are You in Control?
Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...
Teach Engineering
Fun with Bernoulli
Reduce the pressure in the classroom. The second instructional activity in an Airplanes unit of 22 introduces the class to Bernoulli's Principle. Pupils demonstrate the principle by blowing between different objects causing a reduction...
Teach Engineering
May the Force Be With You: Drag
Do not let friction drag you down! The 11th segment in a series of 22 focuses on the fourth force acting upon an airplane—drag. Pupils learn about the effects and causes of drag.
Teach Engineering
Egg-cellent Landing
The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of terminal...
Teach Engineering
Equal and Opposite Thrust in Aircraft: You're a Pushover!
It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...
Teach Engineering
Household Energy Conservation and Efficiency
Are your household devices eating up a lot of energy? Pupils investigate household energy efficiency through a set of activities. They find ways to improve energy efficiency and reduce consumption. This is the 21st installment of a...
Teach Engineering
Understanding Elements
Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...
Teach Engineering
Global Climate Change
The greenhouse effect and its relationship to global warming is the focus of an activity that asks class member to consider the effects of climate change on weather. Pupils work with their families to determine their carbon footprints...
Teach Engineering
Archimedes' Principle, Pascal's Law and Bernoulli's Principle
What do Pascal's law, Archimedes' Principle, and Bernoulli's Principle have to do with fluid mechanics? The included PowerPoint presentation provides the basic definitions and equations associated with the three. A set of homework...
NASA
Lunar Colonization
A five-lesson unit challenges teams to design a complex to allow people to colonize the Moon. The teams first work in order to understand the challenge before becoming experts. Expert teams learn about different aspects needed to survive...
Teach Engineering
Weather Alert
Every time a bell rings ... there is lightning in the area. The activity provides directions to build a model of a lightning detection system. Similar to a system designed by Benjamin Franklin, the system uses static electricity to...
Teach Engineering
Pushing it Off a Cliff
Focus on the conservation of energy, specifically looking at gravitational potential energy and kinetic energy, with a lecture that involves having friends throw light objects at each other to determine which has more kinetic energy and...
Teach Engineering
Energy on a Roller Coaster
Roll with your class into the idea of conservation of energy. Pupils use a roller coaster track to collect data to reinforce the concept of conservation of energy and the influence of friction. Class members then create a graph from...
Teach Engineering
It's Tiggerific!
Spring into elastic potential energy with a activity that provides background information on determining the elastic potential energy of springs and other elastic materials. General energy equations emphasize the conservation of energy...
Teach Engineering
Bridge Types: Tensile and Compressive Forces
Bridges rely on tension and compression to keep them standing. Pairs test this principle by constructing simple bridges and applying a force to the center. Teams use the provided worksheet to record their observations of the reaction of...
Teach Engineering
A Good Foundation
It takes a strong foundation to build a house and a stronger one for a bridge. This resource presents the effects of geology and soil on bridge foundations. Working in groups, the class investigates the interaction of shallow and deep...
