Today’s Chalenge: Amazing Mazes  Today the students created a maze that a marbel could run through including turns tunnels and dead ends. They were to make of them difficult to navigate. We emphasized the need for the maze to have a defined a starting point and ending point. We made sure that they would have a plan before they build just like an engineer would plan. We discussed how engineers make plans before they build but sometimes those plans change and evolved during the design process just as it may have happened for the students when they were making their maze.

Today’s challenge was to construct a ship out of legos. Teacher filled bowls with water. The students were to create ships that must endure the “ocean” waves and lots of heavy cargo. We learned about buoyancy and how to design objects that will float. Will their boat sink or float?

Master Builders: Musical Monsters
The Challenge involved combining ideas to create an elaborate monster. To do this every one of the young engineers started by building their own monster while music played in the background. Then when the music stopped, everyone passed their monster to the left. When the music began again each student added onto a fellow Master Builder’s design. At the end every monster will be unique because of the combination of ideas.
Ideation (the process of forming and relating ideas) techniques are ways that engineers brainstorm and come up with crazy an innovative ideas. One ideation technique involves the passing off of ideas to other people and seeing how they add on to those ideas. This challenge gave the children an opportunity to participate in this ideation technique in a fun and silly way.
Today’s challenge: Bridge Building. A lego person who lives in the United States wants to visit his Lego friend in England. To get across the ocean that separates the U.S. and England, the Lego person can only drive. The challenge today was to build a bridge that is strong enough and sturdy enough so no Lego people falls into the ocean.
Engineering goal: We discussed how to make supports for the bridges using trusses (frames that help support bridges) and arcs (part of a circle or curve).
Here are a few pictures of the kids in action

 

Today the students were to combine exactly 20 Lego bricks together so that when dropped from a defined height they do not break apart. Students discovered that larger,flatter builds withstood the drop test easiest. This was because the force was distributed over a large area making the overall force at each point in the design less. Here is a picture of how students performed the drop test and another picture of our competitors that were left before the final elimination drop test.

 

 

Today they made their name out of legos. First in 2D then in 3D. Next week there will be a Lego competition. Here are some pictures from Monday, Oct 4.
