Still have questions?

What does the subscription consist of?
Your first box will include a robotics kit, and a topic-focused set. Every monthly set contains a new book, a story map, coding blocks, a 3D puzzle, and an educational game. Once your MEL Coding course runs out, you will be automatically switched to MEL STEM.
How much does it cost?
Subscription starts at $29.90/month.
What is the recommended age range?
MEL Coding is intended for kids 4–7 years old. Kids closer to 7 years old will be able to complete all the tasks by themselves, while younger kids will need some assistance from adults. For the other courses, press “Get started”; you will be offered a choice of courses with the recommended age range beside each one.
Are the experiments safe?
Yes, they are. We have made every effort to ensure that our experiments are as safe as possible:
  • They comply with the US CPSC (Consumer Product Safety Commission) requirements for educational sets.
  • Our hands-on chemistry projects comply with The European Committee for Standardization’s (CEN) special list of substances allowed in children’s chemistry sets (EN 71-4).
  • None of our projects include explosives.
  • All of them have been tested with kids and include detailed, visual step-by-step instructions.
Can I buy an individual MEL Science kit?
Currently, there is no such option. However, we hope to introduce this opportunity soon.
Does each set contain multiple-use activities?
The vast majority of the activities can be done multiple times.
Can I cancel or pause my subscription?
