Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

Students utilize computer programs to operate a simple robot.  In this technology instructional activity, students create robots using Lego pieces and simple motors to move them.  Students measure the speed of the robots by...

Students examine engineering by utilyzing legos.

Students listen to Goldilocks and the Three Bears, and work collaboratively to create a chair for a small stuffed animal that will allow it to sit upright and withstand a short drop out of Legos. Students write about the engineering...

Students visualize and manipulate sentences as building blocks, and, given a key, use Legos™ to demonstrate how to construct sentences of variety (simple, compound, complex, and compound-complex).

Students identify and examine various Lego building materials. They discover how to measure Lego blocks and cut out and paste pictures of the Legos on the Engineer's Parts List sheet.

Students are introduced to the function and design of the following Lego pieces: beams, bricks, plates, axles, tires, hubs and bushings. They then work with a partner to build something using only these pieces.

Learners create an assembly line and build a simple car from LEGO bricks. They explore about the effects of Ford's use of the assembly line, auto financing, and increased wages to make his fortune early in the 20th century.

Students examine axles and wheels using LEGO materials. They investigate the uses of axles, gears, and wheels.

Students construct a "voting booth" to gather data using RCX programmable brick and touch sensors. They identify a survey question, construct the booth, and analyze the results by uploading data.

Students read the novel Stone Fox by John Reynold Gardiner. Using Lego RCX units, students build and program sleds to re-enact the "home stretch" of the National Dog Sled Race.

Students are broken up into four groups. Each group will use their knowledge about Egypt to originate a playground for Egyptian children. This will involve brainstorming ideas on paper, building a prototype with Legos or other material,...

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...

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

Learners conduct a variety of experiments on photosynthesis. In this biology lesson, students identify the factors required for the process to occur. They perform computerized experiments to test the amount of oxygen produced when plants...

First graders create a picture graph representing their town's weather for one week.

Students examine the Great Wall of China. In this world wonders lesson, students discover facts about the wall and its construction as they research the landmark. Students build their own replica of the wall in their classroom.

Learners practice problem solving skills and experimental design. They build a vehicle that can traverse "glacial" ice capable of carrying a specific load and glide smoothly, creating as little effort as possible for the skier pulling...

Fourth graders explore The Great Wall of China and use materials to make a class Great Wall of China students measure a portion of the classroom, school or playground and construct a "Great Wall" to scale.

Students choose which building material to use to create their structure and which animal to house. After being read a story, they examine and identify the differnet types of homes mentioned. They take pictures of their structures...

In this lesson, students learn about the chemical reactions that release various pollutants into the atmosphere and what happens when pollutants in the air are exposed to sunlight. They model incomplete combustion using LEGO bricks, and...

A mini-activity, which uses LEGO MINDSTORMS NXT intelligent bricks and light sensors gives students a chance to investigate how light sensors function in preparation for the associated activity involving the light sensors and taskbots.
