Using An Interest-Led Homeschool Science Project

When you select a theme or topic based on your child's interests, you're more likely to get their attention and focus. This smart practice can help you successfully teach, especially a difficult concept, in your homeschool.

After seven years of homeschooling, I've discovered that my boys learn best when we use an interest-led approach whenever possible. They're more engaged and they tend to learn and master the concept or skill faster. After our homeschool science fun experiment that mixed chemistry and nutrition to teach calories and energy, I made sure to include more amazing science kits from Home Science Tools to our homeschool list.

My two older boys are competitive soccer players, for clubs and our local school district. Recently, they've expressed interest in learning more about health careers, nutrition, and the effects of exercise on the human body. Both boys are fortunate to have coaches and trainers who place an emphasis on proper hydration, nutrition, exercise, and sleep for all, especially student-athletes.

To build upon their interests and boost their homeschool science, I've incorporated more hands-on science activities and experiments. These homeschool science projects have helped me overcome my fears of teaching homeschool high school science and provided engaging ways to solidify concepts for my boys.

A Homeschool Science Project to Bust Sports Drinks Myths

When I saw this Electrolyte Challenge Sensor Kit on the Home Science Tools site, I immediately added it to our list of homeschool science projects. The materials in the kit, plus detailed experiment steps, turn complicated chemistry and nutrition ideas (like electrolytes) into real-life applications. Measuring conductance and electrical variables are among other concepts also covered.

As student-athletes, my boys are bombarded with messages about sports drinks being the only way to replace electrolytes. I have my own reservations about those drinks (have you read the labels?!?) and thought this homeschool science project would be a great way to test my theory while teaching an important lesson.

You'll find all the information you need to complete this interesting homeschool science project at Home Science Tools.


Also, I wanted to make sure that my boys knew what electrolytes were, why they're important, and natural options for including them in a healthy diet. As my boys get older, I'm encouraging them to think about what they're putting into their bodies and how it affects them during these crucial times of growth and development. They will be launched into the world at some point and won't have mom lecturing them all the time 😉

This homeschool science project using the Electrolyte Challenge Sensor Kit helps your kids determine what's the best electrolyte drink.

What's The Best Electrolyte Drink?: A Homeschool Science Project

After receiving the Electrolyte Challenge Sensor Kit, I printed out the free printable experiment pack through Science Buddies (scroll down on this page and click "Science Buddies Science Kit Instructions" to check it out).

For this homeschool science project, I also bought a variety of sports drinks and other beverages that we've heard to be good for electrolyte replacement. Beverages tested in our experiment included:

Which beverage do YOU think will have the most electrolytes?

Before we began the actual experiment, the boys and I reviewed the scientific method and discussed how it could be applied to this project. Predictions were made and tallied.

This homeschool science project to determine what\'s the best electrolyte drink is a wonderful way to give your kids practice with the scientific process.

Setting up the materials took about 15 minutes. I recommend having a clean area, like a kitchen counter or table with waterproof cloth, and thoroughly reading instructions prior to beginning this experiment. We accidentally blew a fuse in our first multimeter because we didn't properly set up the wires. Home Science Tools kindly and quickly replaced our multimeter with no questions asked and wonderful advice for our next attempt.

Your kids will discover what's the best electrolyte drink using this kit from Home Science Tools.

Also, make sure to have your homeschool science notebook or another way to record your data close at hand. You'll need to quickly jot down the readings on the multimeter for each liquid.

After testing each liquid, we were shocked by the results! Our predictions were inaccurate. See for yourself!

This homeschool science project using a kit from Home Science Tools is such a fun way to figure out what's the best electrolyte drink.
The winner: coconut water with aloe vera juice!

Coconut water was the winner! And my curious boys had to see if combining the "best" liquids (coconut water, Body Armor, and orange juice) would mean more electrolytes. Yup, it sure did!

Chocolate milk also did well, coming in at 39.4 mA (milliamps).

So, our homeschool science project debunked the myth that sports drinks are the best way to replace electrolytes. We took this discussion a step further and looked at nutrition labels, too.

You'll have the opportunity to talk with your kids about proper nutrition & hydration in this homeschool science project.

We talked about what to look for in a post-sports activity drink and why. Also, possible ways to help your body prepare for exercise by making smart food choices.

The boys can't wait to share their findings with their coaches and teammates. This homeschool science project was a major hit!

This homeschool science project is a fabulous way to teach your kids about proper nutrition & hydration.

What homeschool science project from Home Science Tools would your family love the most?

Sharing is caring!


  1. What ages are your boys? 🙂 I'd love to do this with my 7th grader for a science fair project but maybe it's too old for him? Should I wait until he's older to do it?

  2. We are are also trying this experiment, but after setting the whole thing up we could not get the multimeter to do anything but show 00.0
    We tried putting it on a different setting and it would show the 9v battery on the display but it never changed on any of the liquids when put on the 200m setting for the electrolytes. What are we doing wrong? Did you have problems with your multimeter? We also tried a different multimeter and the same thing happened. Could it be out straw and wire in the solution?

  3. So, what about the taste of the coconut water mixture? Yay or nay?

    Looks like they had a ball, and learned a lot, too!

    1. Oh that's a definite nay! Stuart was barely able to gulp it down lol! Overall, they preferred Body Armor flavor but will go for chocolate milk any day 😉
