Carson Dellosa Stem Challenges, Seasonal, Physical, Life, Earth and Space Science Kits
We absolutely love the Carson Dellosa STEM Challenges kit! It’s been a fantastic addition to our homeschool curriculum and also great for fun, hands-on learning outside of regular lessons. Each challenge is themed around different science topics — seasonal, physical, life, earth, and space — which keeps things fresh and exciting. The activities are well thought out, encourage critical thinking, and use simple materials we usually have at home. This kit is perfect for sparking curiosity and getting kids involved in real-world problem-solving. Whether you’re homeschooling or just looking for meaningful screen-free activities, this is a fantastic resource. Highly recommend!

STEM galore!
Very nice and heavy box. The card stock is very good quality and there is so many activities to choose from! Definitely recommend to anyone and great for homeschooling or even just as summer stem activities. Everything is nicely laid out and easy to understand. The colors, fonts and pictures are great! It's a slim box that could be easily store away.

Good value, but better with adult help and direction
These were nice but I wish there was more direction on the cards. They come in a nice brightly colored and sturdy box which is great for storage and longevity, but I feel like some of the cards were confusing and we had to look up certain things just to make something. I’m pretty smart and hands on, can figure things out and decipher a lot, so when I was questioning things, it makes you wonder how kids are supposed to do it independently. I’m not sure I would agree with the age range, but I do think it’s a good starting point for how things work or whatever.

Great for my homeschooler
These cards are easy for grab and go activities without the prep work, using most items I already have at home. Comes with a lot of cards that are nice and sturdy with categories like animals, weather and body to choose from. I'll be using

Perfect for my 3rd and 5th Grader
Really happy with these. This is exactly what I was looking for. I'm going to have to buy some of the supplies like popsicle sticks, but most supplies are common like tape, paper, straws, etc. I just wish there were more than 30 challenges!

They’re ok, not great
The activities and experiments are neat, but the cards don’t explain how to put the things together, or the science behind the experiments as well as I hoped. I used the cards for ideas for experiments and activities, but then had to research how to execute it on my own. The cards are good quality, very sturdy.

Fun STEM challenges
I am so happy I bought this, great value for the money. It contains various STEM activities that be done in lessons or science clubs. All age ranges can do these challenges and have fun while doing so. The cards are small enough to be stored in any cupboard, draw or storage containers.
