MEL Chemistry

Monthly subscription box covering a new Chemistry topic each month.

Subscription boxes have become very popular. With so many of us doing distance learning from home, MEL Chemistry subscription box might be just the tool you need to teach Chemistry to your 12 year old. Each box includes 2-3 chemistry experiments that all focus on a single chemistry concept which changes monthly.

Your first month comes with a Virtual Reality (VR) headset as the subscription includes chemistry lessons in virtual reality. Each kit includes the necessary ingredients, instructions, and equipment to conduct all experiments. Your child can create liquid wires, paint with light, create a galaxy in a bottle, or make a battery out of a lemon. Looking through each of these chemistry sets, the MEL Chemistry kits were the most exciting and diverse in their experiments in my opinion.

Because each kit comes with enough chemicals and supplies to conduct each experiment 2 or more times, you won’t need a second subscription if you have two children. These kits are suitable for children 10 years and up.

What to Consider When Buying a Chemistry Set For 12-Year-Old Kids

Young boys amazed with chemistry set experiment


There are many chemistry sets that are more gimmicky than they are useful. When considering a chemistry set, look for sets with open-ended experiments, tools, and equipment that can be used for a variety of concepts and experiments, and accompanying content either in print or online that expands the utility of the set.

While a chemistry set that is great at a single thing may have its place, you’ll get more bang for your buck if you invest in a set that can be utilized for many different experiments and leaves room for individual curiosity. 


Chemistry is a broad field. Your 12 year old may be interested in building things and thus interested in modeling chemical structures, or they may be more interested in biochemistry and would be excited to do experiments that included biological samples. Maybe they are artistic and growing colorful crystals is right up their alley.

At this age, it is important to meet young scientists where they are and foster their individual interests and scientific curiosity. If you don’t know what your child is interested in, a subscription chemistry set may be a great choice as it will introduce them to a variety of concepts as they complete the experiments in each box. 

Accompanying Content

Many kits host accompanying content online or provide printed materials. Like the mobile app that identifies molecular structures from the Thames & Kosmos Happy Atoms Modeling Set or the virtual reality (VR) lessons that accompany a MEL Chemistry subscription, this content makes these options more interactive. Often, the online content gets updated or expanded, giving your chemistry kits more value and versatility and can be enjoyed for a longer period of time.

This added functionality adds value to the kit but also gives your young scientist an opportunity to engage with software and/or digital tools that are essential in STEM.

Frequently Asked Questions

What is Chemistry the study of?

Chemistry is the study of matter: its identification, properties, and the ways it interacts with other matter. But chemistry is pretty broad. While there is some overlap and others may distinguish further beyond these categories, chemistry can be divided into five fields.

  • Physical chemistry deals with molecular structures and atomic properties – the smallest components of matter.
  • Organic chemistry deals with compounds that are made of carbon.
  • Inorganic chemistry involves all the non-carbon chemicals.
  • Analytical chemists use some pretty elegant equipment to identify the components of matter.
  • Biochemists – like myself – are concerned with the chemistry that occurs in living organisms.

At what age should children be introduced to Chemistry?

There is no specific age to introduce chemistry concepts to kids. For younger children, it would be useful to focus on chemistry experiments that are colorful, bright, or messy to retain their attention and have fun. Think color changes, eruptions, and crystals. Of course, safety is important, so adult supervision is required for younger kids. 

Kids chemistry experiment

What is the difference between a science kit and a chemistry set? 

A science kit for kids is going to be broader than a chemistry set, though many sets labeled as “science kits” are primarily a combination of biology and chemistry experiments. Because the sorts of experiments in a chemistry set are more focused, they should also be more in-depth and better suited to teaching a specific chemistry concept.
