How much rain can that cloud make? Through a simulation, the class estimates the amount of candy rain contained in different cup clouds. After probing the clouds using different methods, class members adjust their estimates. Participants...

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

What a waste! The last installment of a nine-part technology/engineering series teaches learners about medical waste disposal systems. Conducting a simulation allows individuals to understand how monetary considerations constrain waste...

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

Students design, make and appraise a model wheeled vehicle that is capable of carrying a small load. This activity is part of the unit `Wheels in motion'.

Students design and create robotic cars using Legos and the Robolab program. They hold a "snail race" where the slowest car that can be determined to be actually moving is the winner.
