We have some special guest bloggers this month as Ms. Nelson’s third graders (Longfellow) have agreed to share their thoughts on the Geared Up program with us. Geared Up is an excellent introduction to engineering, using LEGOs. The program was first proposed by Gretchen Junker during our last Call for Ideas. Ms. Junker currently serves as the Program Coordinator, and a VEX Robotics Coach. Stay tuned for more posts from Ms. Nelson’s students, and catch up on those you missed here.

Legos are fun! Legos can be used to build different simple machines, like gears.  Gears can be used in different ways. You can use gears for bikes, trains, and other things.  In the LEGO workshop, we built with gears and some of the gears moved slowly and others moved fast.  When we were building with the gears, it was kind of hard, but we got through it.  Gears can be fun to watch and play with.  In my opinion, LEGOS are awesome!

Do you know what simple machines are?

They are machines that help you do a job.

This week we worked with gears.  We tried 3 different types of gears systems.  When we were finished, we made a really cool gear train that had 3 small gears and 2 big gears.

Do you know what a bunch of gears lined up is called?  It’s called a gear train.

Here are some things that have gears:  bicycles, trains, cars, trucks, minivans, and escalators.

If you have a small gear leading a big gear, your gear system will move slowly.  If you have a big gear leading a small gear, your gear system will go faster.  If you have two of the same size gears working together, they will go the same speed.

LEGOs are fun!  Have you seen the rest of the blog posts about our LEGO workshops?   If not, you should check them out!
