Learning Science: Tin Can Robots & Potato Clocks

|

For Christmas this year, my son asked for science kits. He wanted to have lots of things under the tree that were fun and still helped him learn something about science. We decided this was a great idea! On Christmas morning he unwrapped several fun kits and boxes of amazing things to build, create and discover. Today, I’m sharing the 4M Tin Can Robot and 4M Potato Clock.

Tin Can Robots & Potato Clocks

The tin can robot was a little uncertain at first. We just weren’t sure if we would be able to put it together and actually make it work. But it did! This is one of those builds that requires an adult.

The only thing not included in the kit is a battery and a tin can. You simply use a screwdriver to start constructing the robot and then drop in the tin can and start using the robot.

Turn a metal can into a walking, wobbling, bog-eyed robot that can move. It can be transformed to become a robotic monster too. Cans can be cool! Kit includes parts and instructions, just add a “can” do attitude. Watch your child’s delight and sense of accomplishment with the robot they create. Great for the “science” enthusiast in your family.

Potato Clock

Another one of my son’s Christmas presents was a potato clock. The box includes the wires, metal and small digital clock just waiting for you to add vegetables.

The potato conducts electricity, yet keeps the zinc ions and copper ions separate, so that the electrons in the copper wire are forced to move (generate current). It’s not enough power to shock you, but the potato can run a small digital clock. Chemsitry.com

We were all so excited when we attached the wires and the clock actually worked!

Then of course we had to try other options. Would the clock work if we used lemons or oranges? YES!

What about with coke in 2 little cups? YES!

Would the clock light up if we just water? How about if we made it salt water?

Have you ever made a potato clock or built a tin can robot? Would your kids love learning science like this?
