Second graders explain the relationship between energy and work. In this technology lesson, 2nd graders describe the different uses of machines in their everyday lives. They record observations and data in their science journal.

Students assess how patterns, functions and algebra can assist NASA engineers design new ways of propelling spacecrafts. They explore how electricity and magnetism are replacing the fuel-consuming rocket propulsion. Electromagnetism is...

Middle schoolers visualize a communication system. They encode, decode, transmit, receive and store messages. Students use a code sheet and flashlight for this process. They will also maintain a storage sheet from which they can retrieve...

Students investigate design and the correct use of technology. In this chemistry lesson, students investigate the Bernoulli Principle using hands on bubble making. They link the principle that keeps the bubble aloft to the BP principle.

Learners discuss the types of technology that are used to control the population of sea lamprey in the Great Lakes. They explain the parasite/host relationship and understand the devastating impact invasive species have on ecosystems....

Students participate in a Science and Technology unit designed to introduce the particle theory through drama, demonstrations, and hands-on investigations. They assume the role of engineers and design and build a hot tub for their...

Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.

Students analyze the correct use of technology as it relates to math and science. In this science lesson, students investigate force and weight as it relates to building an object. They build a bridge and draw conclusion based on the...

Students explore how Maglev trains work. In this technology lesson, students discuss the pros and cons of Maglev compared to conventional trains. They build a simple Maglev train model.

Students investigate Microsoft excel. In this technology lesson, students create formulas using excel and apply these formulas to solve relative, absolute and mixed reference cells. They perform immediate and delayed calculations.

Third graders learn how to use solar power.  In this sun, technology and energy lesson, 3rd graders learn how the solar power from the sun can give off energy, learn about solar panels, discuss their uses and benefits, and design a...

Students explain how electricity is transferred from source to load without actual wires connecting the two. In this physics lesson, students explore how wireless electricity was discovered. They cite practical applications of this...

Students construct a hovercraft following specific procedures. In this technology lesson, students explain the physics principles behind hovercraft. They compare and contrast this machine with the aircraft.

Students explore the design process. They discuss why new products are made, examine backscratchers brought in from home and discuss why it is a useful device, and working with a partner draw and construct a backscratcher.

Students discuss difference between kinetic and thermal energy, develop and demonstrate understanding of key concepts and characteristics underlying thermal spray techniques, list items used in their daily lives that are coated, examine...

Students experience the effects of pollution and erosion on a model of a watershed and explore ways to change the outcome.

Learners name the properties of sand as related to the properties and the building of retaining walls. They build a retaining wall and state how retaining walls are used.

Digital, analog, and now binary clocks? The lesson teaches individuals how to interpret binary code. They use an online software program to read binary clocks.

Fe, phi, fo, fum. This activity leads pairs to find the ratio of consecutive terms of the Fibonacci sequence. The pairs find that the Fibonacci sequence can be found in many places. A discussion with the class shows that the ratios...

Investigate desert biomes by creating food chains and food webs. Groups first research feeding habits of organisms in the Sonoran Desert. This information helps pupils draw food chains and webs to determine relationship between organisms.

What can bulldozers and screen doors have in common? Use this lesson on fluid power to find out. It begins with some simple teacher demonstrations, includes a couple of videos, and culminates with an inquiry-based activity to investigate...

Explore the powers of ten while examining a Blue Morpho butterfly wing. Learners discover there is a lot more than meets the eye when one looks close enough.

Join together to investigate truss joints. Scholars learn how to analyze forces at truss joints to determine the strength of truss bridges. They apply the "method of joints" in calculating the tension and compression forces at each joint...

Teams take their cavern designs and build a model from clay or paper mache that can be buried in sand. Testing involves dropping a bowling ball on the buried cavern. Teams dig out their cavern, inspect it for damage, and consider...
