Third grade engineers.... we connect to the science standards of learning and have students use TEGU blocks (purchased with Scholastic Dollars) to create simple and compound machines.
These blocks are awesome because they are magnetic, come with a ton of different shapes and sizes...andy they come WITH WHEELS. Any building material that comes with WHEELS is a must at the elementary school level. We review the basic simple machines: wedge, pulley, inclined plane and wheel and axle. Students discuss, brainstorm and build their machines in groups of 2 or 4.
If you would like to access my materials for this engineering station (they are editable to fit your needs), you can access them HERE (they are free).
Both my 4th and 5th graders will be using the Little Bits this year. In the past, it was mostly just the 5th grade classes but with the changes in the SOL standards, I am definitely going to have my 4th graders experiment with these! These fit into their classroom lesson so well. For this station, I made 2 notebooks that have the different ideas and directions for the students to follow. The PDF I used is HERE. This is 76 pages, so I didn't use all the pages, but I printed the basic circuits: light sensor, temperature sensor, buzzer, and of course the car (an all time favorite to build). Students are also encouraged to free build. Check out the explanation of this station HERE. It includes signs, standards, and procedures. Hope these help!
My engineering students sit at the yellow E table where their materials are stored. The chart I use for this table is below! If you would like this chart that outlines this station, you can make a copy HERE. It covers third, fourth and fifth grade.
