110 Awesome Chemistry Experiments For All Ages

40 total views

Chemistry experiments are a great way to get kids excited about studying chemistry even at a young age. I mean, what child doesn’t think about creating bubbling potions or sending secret messages?

The study of chemistry has a scary connotation for many people. Chemistry has this stigma of being only for really, really smart students who want a career in the sciences. The truth is that, like all science, chemistry is everywhere.

In fact, chemistry experiments for kids can be bubbly and full of fungi! Check out the video below of our Making Peeps Blow Up a Balloon chemistry activity.

It is in the way water freezes into ice. It is in the way apples turn brown when you leave their flesh exposed to the air. Chemistry is in the way sugar dissolves in water.

How does chemistry apply to our bodies? Check out our version of the egg with vinegar experiment. We added a little twist that makes an excellent connection between chemistry and our dental health. We have a 25+ page printable pack to go with it for just $2.95.

Showing how chemistry is involved in everyday life can take that scary factor out of studying chemistry for students. When it comes time to study chemistry, they will be more excited about jumping in.

Chemistry experiments for children in K-12. 100 different chemistry experiments divided into 3 age/grade ranges. Many are ideal when teaching multiple grades at one time in your homeschool, classroom, or co-op.

Chemistry Experiments For All Ages

I wanted to create a resource for you to be able to find the perfect chemistry experiments for your students no matter their age or interests. This post contains 100 chemistry experiments for students from preschool age through high school. I have divided them into 3 age ranges.

  • Preschool and Primary
  • Elementary
  • Middle and High School

Here are a few disclaimers to my divisions of the experiments.

I realize that all students are different and are ready for different levels of experiments. For instance, some students in the elementary age group might be ready for more advanced experiments found in the Middle and High School section, while others need something more basic like those experiments found in the Preschool and Primary section.

Some may question why I put certain experiments in certain sections. First, I looked at the level of maturity I felt needed to conduct the experiment and if parental help was necessary. Next, I looked at the level of understanding the child would need to learn from the experiment.

Some experiments could teach something at different levels or could be done with parental help or independently and still be successful. When this was the case, I put the experiment in the lowest recommended age level.

With all that being said, these are just guidelines. Feel free to try experiments in sections that differ from your students’ age range if you think they would work.
