STEM Series


In this multi-week STEM series, children will participate in a weekly experience chock full of STEM and artistic fun. They'll learn about electricity and magnetism, build and engineer, design and create, and play.

Kids will understand electricity, how it works, and how it powers our home appliances and devices. They'll gain exposure to concepts of switches, transistors, modulating electrons, and conductivity. Experimenting with bar magnets, learning about magnetic forces and poles, drawing magnetic field lines, and magnetizing ordinary objects is always a huge "attraction." They'll make wooden blocks levitate, use magnets to recreate classic paintings, build small pinball boxes, and much more! All materials provided.

Week 1: Intro to magnetism, learning about poles, permanent and temporary magnets, draw a world with a magnetic field surrounding it.

Week 2: Experiment with iron filings, see how a stronger magnet can accrue more iron filings in a clump compared to a weaker magnet; make paintings with iron-mixed paint so kids can observe how iron filings become held within the dried paint. 

Week 3: Make iron filing Jell-O that will be used the following week; make pendulums with magnets to learn about interactions between swinging magnet(s) and static placed ones. 

Week 4: Use balloons to build up an electric charge and then show how it can “bend” or attract water; discuss and learn about electrons, and how they are connected to both magnetism and electricity; dissolve iron agar and try to recover as much iron filings as possible, leaving them in water until the following week.

Week 5: Observe the new, rusty iron filings from the previous week and discuss what’s happened; make floating paper clips, attract bubbles with a balloon, make a piece of plastic float over a tube with static electricity, and remove magnetic attraction with heat.

About Nathan

Scientist and Snowboarder

Nathan is originally from Vermont, and moved to Colorado in 2003 where he earned his Bachelor’s degree in Biology, with a minor in Chemistry. He is skilled in building and construction, as well as in the STEM fields, and believes that kids can learn by doing which also serves to build their confidence. An avid snowboarder, he's tutored students of all ages (his oldest student was 66!) in math and science.

Nathan is vaccinated and boosted against COVID-19.

What Parents Are Saying

We LOVED everything about Grasshopper! The customer service experience was exceptional! I felt like so much intentionality was taken to ensure that the activity would be both age appropriate and fun for my kids. Our experience leader was so easy going and chatted with the kids during the experience, and really took the time to engage and get to know them. We are definitely going to be using Grasshopper again! Thank you!

Grasshopper offered my daughter an opportunity to learn in a vibrant, fun setting that was continuously customized for her attention span and interests. Her Grasshopper teacher was fun, engaging and supremely personable. She took the time to get to know my daughter before diving into anything. I felt more than comfortable leaving my daughter in such capable hands…and love that she truly learned some new things from the experience. We will be using Grasshopper regularly to broaden her horizons and expose her to new concepts in a safe and compelling way. The icing on the cake is that the experience took place in our home, at a time that was convenient for us!

Our Grasshopper experience was amazing! I have four very curious kids at different ages with different interests, and the experience had all four of them engaged the whole time. Also, as an educator, I was very impressed with how the teacher led the program. She obviously knew what she was doing, and the minute she left, my kids were asking for another experience.

Great experience for the kids! They were super into the science!

Nate showed up with a giant box of magnetism activities for the kids. He kept three 4-year olds entertained and focused for two hours. We were thrilled.

Our son loved the magnetism experience. He laughed, he was engaged, and he learned about magnets. He’s a four year old scientist and this one was perfect for him!
