Hi STEM Sparkers! I know it's been over a month since we've posted, but we've been busy with work and school and getting Jack vaccinated! I really hope the COVID vaccine is around the corner for children 0-5; that's my first holiday wish. My second holiday wish is that everyone in the STEM Spark community is doing alright, and my third wish is that I hope everyone will participate in the 12 Days of STEMas! Whether you just finished celebrating Hanukkah or plan to celebrate

Welcome back STEM Sparkers to our holiday STEM product reviews and giveaways! The product we're reviewing this week was recommended to us by a few of our engineering friends, and I have to say, it's a pretty cool STEM product: it's the the Kamigami Robot Lina Ladybug! But before we jump into this review, a little robot humor. What kind of droids live at the North Pole? Snobots! Har, har, har (groan)! Will your kids like it and/or will you hate it? Jack keep asking when w

STEM Sparkers, I can't believe the holidays are right around the corner (here in the US)! We have all these grand plans again to review products and give them away from now until the New Year here at STEM Spark, so... let's get to it! No time to waste! Unless your Santa Claus or Hermione Granger or Doctor Who or etc and can manipulate time. Anyway, first up is the Lego BrickHeadz Thanksgiving Turkey. Will your kids like it and/or will you hate it? I showed Jack the box and

I'm so excited! I'm on a panel for Phoenix FanFusion called "Take Chances, Make Mistakes, Get Messy! Fun DIY Science Projects." I'm on the panel with a biologist and two astronomers, and I can't wait to represent STEM Spark by sharing different science experiments with the public. And to tie into the "Fun DIY Science Projects," STEM Spark is going to review the Lauri Fun with Magnets kits and one lucky STEM Spark reader will win a kit (see the Rafflecopter below)! Will yo

Happy Earth Day fellow STEM Sparkers! There are so many great ways to celebrate our wonderful Earth, and here on STEM Spark we can't think of a better way to celebrate than by reviewing and giving away this awesome Melissa and Solar System Floor Puzzle! Will your kids like it and/or will you hate it? Jack not only likes this puzzle, he loves it. He kinds of loves all puzzles, but since he's been learning about the solar system recently, he was really excited to open this p

STEM Spark loves Women in STEM. STEM Spark loves NASA. STEM Spark loves Lego. So put them all together, and STEM Spark loves the Women of NASA Lego set! We're going to review this product a little different this month. Since it's Women's History Month here in the States, we're going to share a little bit of history about each woman featured in the Women of NASA Lego set!

For some more STEM-entine's fun, I've made a quick video tutorial on how to make a Lego heart! This Lego heart is geared towards people whose dexterity is limited; so like preschoolers, arthritis patients (like me), the elderly and so on. Plus, the bricks should be easy to find in any Lego stash or store. I think it will make for a fun STEM project to do with your family and friends on Valentine's Day, so have fun building the heart STEM Sparkers! You won't wanna Lego of t

This summer I came across Tegu Travel Pals, and I was excited to get one for Jack-- it's a wooden, magnetic tangram puzzle that one can take anywhere! Well, we finally got around to trying ours out last night, and you can see Jack and mine's review below. STEM Spark is also raffling of the exact same Tegu Travel Pals Spaceship; see directions below! Happy STEM-i-days! Will your kid(s) like it, or will you (the adult) hate it (that it don't matter if they like it)? Jack lov

Hello! So I've already reviewed magnetic building blocks/magnetic tiles on this post, but I feel like this STEM toy is so popular right now that I want to do another giveaway of the magnetic tiles for the holidays. It will make a great gift under the tree! Here's the overall review summary of this toy: "So in summary, I'd give this STEM product a 4.5 out 5. Very fun and easy to build with and to learn about different shapes, as well as they come with their own carrying ca
