My 10 year old is the main one doing the experiments. This comes with excellent detailed instructions. So far all pieces are great quality. We have opened rose quartz and tigers eye crystals and they are indeed real. (I collect crystals so I can tell the difference.) It is easy to open each daily door. This is a great value for the money! It even comes with a pamphlet with extra experiments you can do. Review: Advent, but Make It a Full-Time Job - As Thanksgiving approached, I was in the market for an Advent calendar for my boys. We had already exhausted most varieties, so when I spotted the National Geographic Mega Science Advent Calendar, the science educator in me was instantly sold. I imagined calm mornings with a quick, tidy experiment before rushing out to catch the bus. I hesitated only briefly at checkout. Was this too ambitious? I reread the description and reassured myself that some days were simply rocks, gems, or minerals. That seemed reasonable. I clicked purchase and spent the next few weeks eagerly awaiting December. The first few days were genuinely fun—new knowledge, excitement, curiosity. What I didn’t anticipate was a winter illness taking over our house, paired with ten school spirit days requiring coordinated outfits and enthusiasm I did not have. Somewhere along the way, I began actively hoping the next day would be a rock. Ideally several rocks in a row. Instead, National Geographic escalated. Some days now included two or three experiments. We were no longer pacing ourselves; we were rocketing toward the finale like a Fourth of July fireworks show that would not end. The final days before Christmas became a chaotic mix of gift wrapping, baking, shopping, and science experiments, interrupted only by a few merciful rock days. The final experiment, “Is That Gold?”, promised to “get messy” and required a frigid excavation outside of a rock I was certain would not be gold. This kit did not disappoint. By this point, the real reward was finally throwing the remains of this Advent calendar—and possibly part of my soul—into the trash and moving bravely into the new year. 5 stars, highly recommend ## Features - 24 DAYS OF SCIENCE - Each day of December as Christmas approaches, kids will open an exciting science experiment to conduct from our world-class science kits, or a gemstone specimen to add to their collection! - CONDUCT 13 FUN EXPERIMENTS - We selected 13 incredible experiments from our science kits for this advent calendar.

Is there a way to get the missing pouch of red cabbage powder?** A: There is a chance that it may have slid into another days compartment. If you are able to carefully open the top of the box to slide the inner tray out you should be able to locate the red cabbage powder and save the day! If it is not there, please contact us directly using the customer support info located on the bottom of your kit so we can further assist you directly. **Q: How would an adult feel about getting this?** A: Depending on the individuals interests, abilities and limits this could be suitable and a fun throwback to your youth advent calendar! It might make them feel like a little kid again! **Q: Which natgeo advent calendar should i buy? one with just the stones or the one with the added experiments for my 9-y precocious grand child?** A: My Grandsons love the experiment ones. **Q: Are these the same experiments as the 2022 calendar?** A: Some are similar. Most stones are the same. Experiments are same yet different… crystal tree… last year we made snow (grand daughter had a reaction to powder). Kids lo es ot so much, I am willing to repeat as are they. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fun for all *by S***Y on December 6, 2025* This has been very fun so far!

Each of my boys (ages 6, 10, and 11) choose an advent calendar each year and this one was selected by my 6 year old. He has been able to do most of the experiments with minimal help from his older brothers. Not every day is an experiment, some days are gems or stones. The included book tells you what each day holds so if you know you are going to have a busy morning you could have your kid go out of order and choose a gem on that day (this is what we do). There is also plenty of material to complete some of the experiments multiple times so the boys have taken the kit over to their grandparents to show them some of the experiments that they have already conducted at home. Overall, I would recommend this kit for any kids into science! ## Frequently Bought Together - NATIONAL GEOGRAPHIC Science Kit & Rock Collection Advent Calendar 2024 – Jumbo Advent Calendar with 24 Days of Science Experiments, Gemstones & More for Kids, STEM Projects for Kids Ages 8-12 - NATIONAL GEOGRAPHIC Gemstone Advent Calendar - 2024 Advent Calendar for Kids with 24 Gemstones to Open Each Day, a Complete Rock Collection Christmas Countdown Calendar with Mini Gemstone Dig Kit - Blue Marble NATIONAL GEOGRAPHIC Dinosaur Advent Calendar 2024 - Christmas Countdown Calendar with 24 Dino Activities & Figures, Paint A Dinosaur, Create a Clay T.
