Students build a water filtration system. In this water quality lesson, students work in groups to construct water filtration units that can purify contaminated water. This lesson is part of a larger unit on water quality.

Students research and study the life and reproductive strategies of reef building corals. They examine how coral reefs can produce high levels of biological material when they are surviving in areas of low nutrition.

Students study the changes in land formations caused by water erosion. They work in groups to build a model of a mountain composed of materials that will best withstand water erosion.

High schoolers investigate the concepts related to the practice of designing and building large scale buildings. They conduct research using the internet and other resources in order to apply mathematics and architectural design...

Young scholars use waste materials to build a snowman decoration. For this reusing lesson, students create a new object out of disposable items left over from the holidays. Young scholars discuss ways of cutting down waste. Students...

Students explore environmental care by participating in a trail building exercise. In this topography instructional activity, students collaborate in small groups and utilize building materials to create a trail in a nearby park or...

Learners brainstorm lists of land uses, gather pictures of them, and create a collage. They research land uses in their communities by contacting local agencies. They make charts of the land use planning systems and their impact on...

Students use the internet to research the advancements in transportation on rivers throughout 1800 and 1900. In groups, they use a picture to build their own model of a steamboat using everyday materials. To end the lesson, they use...

A radio receives radio signals, converts them to an electrical signal, then converts this signal to a sound signal, and amplifies the sound so people can hear it. Class members use this information to create a short-wave radio antenna...

Have small groups in your class construct working hygrometers as an example of the benefits of using sensors in engineering. This activity can be used during a weather unit when covering humidity or in a STEM activity as a preparation...

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts:...

In 1993, five biomedical engineers in Edinburgh, Scotland, created the first functional bionic arm. In the activity, learners explore the world of bioengineering through discussion and hands-on exploration. In groups, participants...

Research various types of bridge designs. Your class will be asked to consider what it would be like without bridges while learning about how they work. They will construct a model bridge based on given parameters. They then calculate...

The San Andreas Fault moves about two inches a year, approximately the same rate fingernails grow—crazy! The third lesson in the series allows for hands-on exploration of various fault formations. Through the use of a Popsicle stick,...

Sometimes scientists learn more from unexpected findings than from routine analysis! Junior oceanographers dive deep to explore hydrothermal vent communities in the fourth lesson in a series of five. Scholars examine data and look for...

Turning white light into colors only takes a little scientific know how! Young scholars create their own spectroscope in a hands-on activity exploring the properties of light. Using a diffraction grating, they discover how white light...

How can a robot measure the length of something when we don't know how far the camera is from the object? The lesson explains the concept of perspective and many others. Scholars apply this knowledge to judge the length of fish and the...

Everything has potential energy; learning to use it is the key to understanding all types of energy. Scholars learn the difference between kinetic and potential energy. They then apply the concept to drawing examples of both types...

Are the earth's oceans really just giant batteries, waiting for their energy to be harnessed? Middle school mechanical engineers will be shocked by the amazing amount of energy that forms around them after diving into part four of a...

Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

How do Olympic runners succeed in physically demanding events like the 400-meter dash? Physiology scholars explore the relationship between acids, bases, and the muscular system through a scenario-driven activity. The activity focuses on...

Step aside, fancy glasses... it's time to create a solar eclipse viewing camera of your own using nothing more than a milk carton. 

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

Use primary text documents to learn word roots. Learners listen to a reading of the Declaration of Independence and highlight words they don't know. They compile these words and guess their meanings. They discuss roots, prefixes,...
