Mysterious Movements - An Adventure in Magnetic Movements

As a mechanical engineer, I like projects that move, and I never really considered a project in magnetism until I came across this kit from a local resource store for teachers (RAFT). And to be honest, I never thought I'd sit here and play with magnets for an hour.

I was going to explain what magnets are, etc., but I found this great site that explains everything about magnetism. So, I decided to add a link to that here instead of trying to explain it myself.



This is the kit I bought.

Parts from the package

So, this is what we're doing today. An Adventure in Magnetic Movements.


Center core assembly.


Center core assembly completed.




Pill magnets move as if they are strung on a string. The pill magnet pairs will move to be evenly spaced around the ring magnet.



It's the same with 4 pill magnets. Pill magnets move as if they are strung on a string. The pill magnet pairs will move to be evenly spaced around the ring magnet.




It's the same with 6 pill magnets. Pill magnets move as if they are strung on a string. The pill magnet pairs will move to be evenly spaced around the ring magnet.




As more pill magnets are added, the pill magnets move equidistant apart. 
The pill magnet pairs will move to be evenly spaced around the ring magnet.



I used the magnets from the kit, but you can use any magnets you find. 
Small or big, it really doesn't matter.

Again, I didn't realize how much fun I could have with some simple magnets. 
I hope you do, too.

Have a great day.

Scissor Lift 1 (Mechanisms) - Page 212, Build #237

I love things that move, and we're making this Scissor Lift today.

Just like the previous Claw Gripper, I was trying to build a vehicle and put this on top with Mindstorm controlling it, but I didn't have enough time. So, I guess I'm going to have to build this in stages, too.



These are the parts I'm using today. 





































I had a lot of fun building this. I hope you get a chance to build it, and see it work. I like watching the worm gear work as the Scissor Lift goes up and down.

Enjoy!

PS - updated with videos!

Claw Gripper 1 (Mechanisms) - Page 198, Build #231

Did I tell you I love LEGOs?

Today, we're building this Claw Gripper. I was trying to build a vehicle and put this on top with Mindstorm controlling it, but it's been too crazy lately. So, I guess I'm going to have to build this in stages.


And this is what we're building today.



I like building these mechanisms because they are simple enough for an elementary students to build, but interesting enough to engage them deeper in Engineering and Science topics.

These are the parts I used to build this mechanism (you will need a couple of extra yellow part because they had rolled off the table, and I didn't realize it).



So, let's build it.




















I had a lot of fun with this project.

Have a great day!
