STEM challenges use a ton of skills but can require as many or as little supplies as you like.

They are also great for kids of all ages. With younger kids you can give them a problem to tackle.

With older kids, you can impose more rules by limiting their resources or adding other rules to make them think through a different solution ie. they can only use a certain number of marshmallows or toothpicks.

What is STEM?

STEM is the education plan of teaching science that covers science, technology, engineering and math.

Science is all around is and with the explosion of technology it’s such an important skill to explore and discover the world around us.

It fosters innovation, discovery, problem solving, and collaboration skills that can’t get gained from other subjects.

With so many technological changes, STEM can be a successful career path for kids to prepare them for the future.

I love STEM challenges for any kids because it challenges them to use their brain in different ways. My daughter enjoys STEM challenges for their creativity and the things that she can design.

My son who is more logical and math oriented enjoys coming up with a solution to a a problem and uses a more analytical approach.

We just decided to have a ton of fun so they decided who could make the tallest snowman. We had our ruler out to measure their creation.

The rules were that the snowman had to stand up on it’s own for 20 seconds.

This proved to be harder than they thought.

Their snowman could stand for a short time but would then flop over.

This was my daughter’s creation and he had a hard time standing up. She build a support system for him that was composed of marshmallows that went behind him to help hold him up.

When I asked my 12 year old son to create the tallest snowman, this is what I got.

He first build the snowman’s body going straight up but then he ran into the same problem.

He wouldn’t stand up.

So then he created a base for him to help him support himself so he was able to remain standing on his own.
