I am a big fan of experiments because they are the face of science! Now, I know the hands-on aspect of science is not without its challenges. But there is nothing like seeing the amazement spread across your child’s face when they see science in action. These ten experiments will lead to that look of wonder time and time again – let’s dig in!
Experiments for Biology
#1 – Extracting Fruit DNA
Did you know that you can extract DNA from the fruit in your kitchen, some rubbing alcohol, and dish soap? You can!
You can use strawberries, bananas, and even grapes to extracting DNA at home – it takes a few steps, but it is totally worth doing with your kids.
#2 – Simple Digestion Experiment
This one is part disgusting and part amazing, but it will help your students to understand what happens to their food once it passes their lips!
Show your students the effects of the first steps of digestion using crackers and some iodine. If you want to take this a step further add a bit of cola to the bowl with the “chewed” crackers and watch what happens to food in the stomach!
Experiments for Earth Science & Astronomy
#3 – Explore Convection Currents
Convection currents are found in the atmosphere and in the ocean. These currents are due to the transfer of heat in the air or in the water.
You can watch these convection currents in action in glass on your table. Your students will love watching this happen, so be sure to make more than one colored ice cube!
#4 – Explode a Volcano
This is a classic, must do experiment! Every student simply must explode a volcano before leaving your homeschool.
This simple baking soda and vinegar volcano is one that anyone can do with stuff you already have in your kitchen cabinets. If you want to step it up a bit, use a bottle of cola and a few Mentos®!
#5 – Watch the Crayon Rock Cycle
The three major types of rock – sedimentary, metamorphic, and igneous – can be hard to say and hard to understand how they are formed.
But, if you grab a few crayons you can show the rock cycle in a few minutes in a way that your students will remember for a long time!
#6 – Eat the Moon Phases
Food and science are always a great match. And experiments with chocolate are almost guaranteed to bring smiles all around!
So grab a bag of Oreos® and make some cookie moon phases with your students. You can test a few out before you hand the bag over to your students – I promise I won’t tell!
Experiments for Chemistry
#7 – Marker Chromatography
This is my all-time favorite experiment to do with kids! It allows your students to play with science as they unleash their creative side.
You can do marker chromatography with coffee filters or t-shirts – just make sure that you use permanent markers, like Sharpies, as the washable ones will run away!
#8 – Make a Polymer Slime
I have yet to meet a student who wasn’t fascinated by polymer slime. For making a basic version at home, you will need glue, a bit of water, and some Borax, which you can find on the laundry aisle.
These three recipes for homemade polymer slime range from super easy to a bit more technical, but whichever one you choose your students will have a blast making this stuff!
Experiments for Physics
#9 – Lego Balloon Car
LEGO bricks can be used in your homeschool for retelling history or for making a model cell. But our favorite way to use LEGO bricks is to make cars for a physics-inspired race.
Having a Lego Balloon Car Race is a fantastic way to bring some science excitement to your Friday Fun Day plans!
#10 – Homemade Water Clock
Way before smartphones and wall clocks, people used to tell time using the sun and water.
This homemade water clock is a fun way to partner history and science! Your students will be amazed at the power of gravity to help you keep track of time.
