The American Association for the Advancement of Science calls itself "The World's Largest General Scientific Society." Here you will find up-to-date news on scientific discoveries, including the EurekAlert! which has breaking news for...

Created by teachers for classroom use and officially supported by Mojang, the company behind Minecraft, MinecraftEdu contains a set of powerful yet simple tools to fine-tune the Minecraft experience for learning. Teachers in over 40...

A dark side to the Jazz Age was the increase in the fear of Communism. Read about the federal government's actions to stem anything that was thought to threaten American security.

[Free Registration/Login Required] During this MEA simulation, kindergarten students will determining the top three flavors of ice cream bars that an ice cream truck should serve. Students must work in cooperative groups as they work to...

[Free Registration/Login Required] During this MEA simulation, kindergarten students will be preparing for a move to another state. Students must work in cooperative groups as they determine which moving company will be the best for...

Students quantify the percent of light reflected from solutions containing varying concentrations of red dye using LEGO MINDSTORMS NXT bricks and light sensors. They begin by analyzing a set of standard solutions with known...

Students learn about and practice converting between fractions, decimals and percentages. Using a LEGO MINDSTORMS NXT robot and a touch sensor, each group inputs a fraction of its choosing. Team members convert this same fraction into a...

Students learn about nanocomposites, compression and strain as they design and program robots that compress materials. Student groups conduct experiments to determine how many LEGO MINDSTORMS NXT motor rotations it takes to compress soft...

Students create model elevator carriages and calibrate them, similar to the work of design and quality control engineers. Students use measurements from rotary encoders to recreate the task of calibrating elevators for a high-rise...

Students learn about rotary encoders and discover how they operate through hands-on experimentation. Rotary encoders are applied in tools to determine angle measurements and for translations of angular motion. One common rotary encoder...

Students learn that fats found in the foods we eat are not all the same; they discover that physical properties of materials are related to their chemical structures. Provided with several samples of commonly used fats with different...

Using the LEGO NXT robotics kit, students construct and program robots to illustrate and explore the Fibonacci sequence. Within teams, students are assigned roles: group leader, chassis builder, arm builder, chief programmer, and...

Students use LEGO MINDSTORMS robotics to help conceptualize and understand the force of friction. Specifically, they observe how different surfaces in contact result in different frictional forces. A LEGO robot is constructed to pull a...

Students use conductivity meters to measure various salt and water solutions, as indicated by the number of LEDs (light emitting diodes) that illuminate on the meter. Students create calibration curves using known amounts of table salt...

In an interactive and game-like manner, students learn about the mechanical advantage that is offered by gears. By virtue of the activity's mechatronics presentation, students learn to study a mechanical system as a dynamic system under...

Students discover how gears work and how they can be used to adjust a vehicle's power. Specifically, they learn how to build the transmission part of a vehicle by designing gear trains with different gear ratios.

Students use a LEGO ball shooter to demonstrate and analyze the motion of a projectile through use of a line graph. This activity involves using a method of data organization and trend observation with respect to dynamic experimentation...

Students experience haptic (the sense of touch) feedback by using LEGO MINDSTORMS NXT robots and touch sensors to emulate touch feedback recognition. With four touch sensors connected to LEGO NXTs, they design sensor attachments that...

Students measure and analyze forces that act on vehicles pulling heavy objects while moving at a constant speed on a frictional surface. They study how the cars interact with their environments through forces, and discover which...

Students explore materials engineering by modifying the material properties of water. Specifically, they use salt to lower the freezing point of water and test it by making ice cream. Using either a simple thermometer or a mechatronic...

Students are introduced to the concept of light pollution by investigating the nature, sources and levels of light in their classroom environment. They learn about the adverse effects of artificial light and the resulting consequences on...

Students are given the opportunity to visualize and interact with concepts they have already learned, specifically algebraic equations and solving for unknown variables. Students construct a balancing seesaw system (LEGO Balance Scale)...

Students groups act as aerospace engineering teams competing to create linear equations to guide space shuttles safely through obstacles generated by a modeling game in level-based rounds. Each round provides a different configuration of...

Students investigate the materials properties-such as acoustical absorptivity, light reflectivity, thermal conductivity, hardness, and water resistancea-of various materials. They use sound, light and temperature sensors to collect data...
