Real Teacher Review: “We LOVE this microscope for our classroom (pre-K, 4-year-olds). The magnification is similar to that of a magnifying glass, but the two-eye viewer and focus nob allow the students a different experience that a magnifying glass cannot give. I personally love that it is easy to clean, easy to store, and pretty durable! Highly recommend this product.”

Stomp Rocket Original Jr.

Kids playing with pressure-activated foam Stomp Rockets

This is a classic kids toy, with science fun built right in! One of our favorite features is that you can buy replacement rockets if you lose or play the original ones past their prime.

Real Teacher Review: “Who knew such a simple design could provide hours of fun and entertainment! Put together in no time, the stomp rocket junior had my little ones enjoying and giggling instantly. What’s more, as a science teacher I love the physics lesson this provides. The rockets are more robust than some I have seen and are cut from one continuous piece of foam—others I have tried with a plastic body and red foam head become useless when the glue keeping the foam head on disintegrates and re-gluing proves fruitless. These do not suffer from that effect and what’s more—they glow in the dark! Who wouldn’t like that? I would thoroughly recommend these stomp rockets.”

Curious 2 Learn Building Blocks

Unique building blocks with a flower-shaped design

The unusual design of these building toys draws kids in, and they can get really creative when assembling patterns and other structures. This is another one of those STEM toys that older kids will want to get in on too.

Real Teacher Review: “I was a STEM teacher for a year and a half, and I still have a children’s STEM event at my current place of work. I use LEGO-style blocks, big-blocks, marble-runs, and all kinds of assorted building blocks and toys at the events. These went over very well. In fact, one table of children pushed the LEGO-style blocks aside in favor of these. They are very easy to construct 3D shapes with. The pieces also hold together well, so kids are less likely to become frustrated when creating a structure.”
