Compression, the process computers use to store information, is the focus of a resource that presents two different stories that describe the concept of compression by eliminating repeated letters and replacing them with a...

Examine the science behind computer communication. After defining the properties of magnets, learners simulate how a computer hard drive works by sending each other binary codes using the magnets. They use these communications to...

Mid-ocean ridges, rift valleys, island arcs, mountain ranges, earthquakes, volcanoes ... there are so many features associated with plate tectonics. The 14th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography...

Look at it go. The resource, the third in a series of five using a Roomba, explains the different types of movements a Roomba makes, then challenges pupils to create computer codes that will cause the Roomba to travel specific paths.

Introduce your classes to sensors and actuators in robots — specifically to the Roomba. Pupils develop programs that make Roomba utilize its different sensors.

See what you cannot see by getting a little creative. An intriguing lesson has learners use lasers to explore X-ray diffraction. Given a box with unknown structures, they shine a laser through the box and interpret the results....

What is the difference between a comet and a meteoroid? An educational lesson includes five demonstrations of how the atmosphere can inhibit our ability to measure many things in the galaxy. 

Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

What does the future of energy look like? Junior engineers collaborate to discover a solution to the global energy crisis during a very hands-on lesson. The unit focuses on learning through collaboration to develop a deep understanding...

Can turning on the television lead to toxins in the food supply? The lesson offers an opportunity for young scientists to complete guided research. A worksheet lists each question as well as the web page necessary to answer the question....

"Self-guided Computer Activity" simply means that young chemists read through the slides and take notes about atoms along the way. There is an abundance of text on each slide, making this a comprehensive introduction to atomic structure....

Students research sea life using laptop computers. In this sea life lesson, students participate in a field trip to the beach and enter observations into their laptop computers. Students classify shells and sea life.

Students read and discuss short articles which "brief" them on the coming mission. After they read each of the articles, they discuss the main ideas and the requirements for mission training. This is an introductory lesson to a...

Students describe the impact of antibiotics on disease. They describe what infections antibiotics are useful for. Students are introduced to the idea of antibiotic resistance as a way to focus on antibiotics and the mechanisms by which...

Students discover how capacitors help store data.  In this computer science lesson, students investigate how capacitors can store an electronic charge, eventually helping computers store data.  Students create their own...

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

Students explore the dose response principle, an introduction to what the "natural log" (ln) is and how it behaves. They create and analyze a dose response graph.

Young scholars review basic weather concepts and terminology, and explore weather modeling tools.

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Students use a computer program to study elements and the periodic table. They follow the directions on the computer program, and answer the questions presented. The program is self scoring, and students may print a certificate that...

Students investigate how to plant a seed. In this gardening lesson, students listen to the book I'm a Seed and research the materials needed to plant a seed. Students present the information they found.

Fifth graders use scientific skills and processes to recognize how living things depend on one another and on the environment for survival and the human use of natural resources impacts the environment. Explain how Earth's surface...

Students explore the science of toxicology and the relationship between a toxic reaction (response) and amount of substance (dose). They observe two demonstrations illustrating the concept of dose-response.

Learners research plants. In this researching lesson, students watch a video about the different ways to research a topic before writing about it. Learners use the information gathered in this video to learn more about plants. Students...
