Lego Challenge: Build the Ultimate Playground

Last week, my kids were reading through all the old Lego posts here on the blog. Their favorite posts to read were the Lego Challenge ones. Afterwards, they wanted to do a Lego Challenge and have me blog about it. Of course, I said yes, because Legos and education and blogging are always a great idea!

For this Lego Challenge, I had them build a playground that uses simple machines. The idea comes from this site: Educating Young Engineers. Two of my boys also wanted to write about their playgrounds, so I’ll be posting their writing along with the pictures of their playgrounds.

Weekend Build: Lego Carousel

As an Amazon Associate I earn from qualifying purchases.

My last post was about the Booster Bricks subscription we bought our kids for Christmas. It is not just a box of random Legos though. The box includes challenges as well as an online Facebook group to participate in: weekly challenges, builds, and games.

This past weekend’s challenge was to build a Lego Carousel. Two of my boys, Matthias and Ian, worked pretty hard on it so I thought I’d post about it here.

For Christmas, we also bought our kids one of the largest Technic sets currently available: The Bucket Wheel Excavator. At almost 4,000 pieces, this is a huge set. We have to confess that we bought it mostly for the pieces. My boys used some of those pieces in their Carousel, which is why it looks a bit skeletal.

Matthias and Ian used a medium motor to power the Carousel. The gear assembly is pretty simple. The circular yellow pieces form a large gear.

You can see the gear and motor assembly inside the walls in the picture above. The switch is located outside the walls.

The Carousel sits on the small gear attached to the motor as well as 3 flagpole pieces that help keep the Carousel level but still allow it to rotate.

I was really proud of my boys for keeping at this build. They had no instructions and only a little bit of help from Josh. He helped them figure out how to downgear the motor so the Carousel wouldn’t spin too fast.

Here is a quick video of their Carousel in motion!

They didn’t mess with the design element too much but that is ok with me. I’m more interested in their learning the mechanics of it. Design can come later!

Learning About Science By Growing Radish Seeds: Day 5

I have fallen behind, and this is from Friday’s work.

On this day they used two of the small pots they made earlier. One of the little pots had 12 of the sprouted seeds put in it. This is to show the effects of overcrowding plants.

Another mini pot had 2 sprouted seeds put into it.

So far this has been an interesting experiment. I think it goes over many of the things that people do wrong when planting seeds. Ranging from overcrowding to water issues.
