What’s the Fastest Way to Bake a Potato? Baked Potato Science Fair Project

It’s science fair season! Are your kids working on something yet? This year, for kindergarten, I got to flash back to the science fair project I did as a kiddo. We asked What’s the Fastest Way to Bake a Potato?  And learned all about the Scientific Method. Keep reading for the delicious and easy science fair project and free printable workbook.

This baked potato science fair project is a delicious STEM activity for kids and a great way to learn about the scientific method.

Baked Potato Science Fair Project Supplies Needed

You don’t need too much for this project and you can definitely use what you have.

  • Potatoes – big Russet style potatoes worked for us. Try to get similar sized potatoes to make the experiment fair
  • Aluminum foil (regular and heavy duty if desired)
  • Baked potato pins
  • Timer
  • Oven and/or microwave

This baked potato science fair project is a delicious STEM activity for kids and a great way to learn about the scientific method.

Potato Scientific Method

At the heart of any good science fair experiment is the Scientific Method. This framework helps think through a problem and come up with an answer. I’m going to walk you through our steps in this project, but be sure to challenge your kiddos to do this themselves. And don’t worry about kids being too young! Preschools can totally comprehend this process even if they can’t write the answers down yet. Turn it into a conversation for them.

This baked potato science fair project is a delicious STEM activity for kids and a great way to learn about the scientific method. Plus there's a printable workbook to make doing to project easier.

 

Potato Scientific Method

1. Ask a Question – First up is figuring out the problem. The other night we were trying to get dinner on the table, fast. But since I don’t have an Instant Pot, the baked potatoes were the bottle neck. So our question is: “What’s the fastest way to cook a baked potato?”

2. Do Research – So we Googled it. And up came a lot of ideas like wrapping the potatoes in aluminum foil, using baking pins and microwaving the potatoes can all help speed up the process.

3. Form a Hypothesis – We guessed that microwaving a potato would be the fastest way to bake a potato.

4. Design an Experiment – We decided to try 7 different cooking methods. Because that’s how many potatoes we bought! But get creative and make up your own, too.

(SAFETY NOTE!! Don’t use the aluminum foil or pins in the microwave!!!)

Baked in 350° F oven:

  • Plain potato
  • Potato wrapped in regular aluminum foil
  • Potato wrapped in heavy duty aluminum foil
  • Potato with baking pin
  • Potato wrapped in regular aluminum foil with baking pin

Baked in microwave at full power:

  • Plain potato
  • Plain potato in glass bowl with plastic wrap over it

You also need to decide what you call done or cooked. We called the potatoes done when a fork easily slid all the way to the center with no resistance.

5. Record and Analyze Data – Grab a notebook and record the cooking times. And be sure to leave enough time to test the potatoes. Potatoes can take an hour to bake in the oven, so don’t try to finish this up right before bed time. For each potato, write down the preparation (like foil and pins) and record the cooking time. Then sort the results from slowest to fastest.

6. Draw a Conclusion – Our results showed that if you need speed, the microwave is the way to go. But if you want crispy potato skin? Go for the oven with only the baking pin. The aluminum foil steams the potatoes a bit, so they’re not quite as crispy.

7. Communicate Your Results – We did this over a delicious dinner of loaded baked potatoes :) It’s a great conversation starter for families!

Baked Potato Recipes

And because if you do this science fair experiment, I know you’re gonna need some recipes for all those baked potatoes :) Yummy recipes like twice-baked potatoes, baked potato casserole and more! We love these Twice Baked Potatoes from Crafty Morning.
