Everyone loves an icky, sticky experiment so I’ve pulled together my favourite gross science experiments and also have some exciting news at the bottom of the post about my new book, Gross Science Experiments.
Make fake blood, a pretend scab, model the digestive system and more science to make you say “YUCK”!
Gross Science Experiments for Kids
Make your own fake blood
This fake blood recipe is great for a spooky Halloween activity but also illustrates blood clotting so is educational as well!
Staying with the blood theme, I have a great recipe for making jelly scabs!
Digestive System Model
This gross demonstration of the digestive system is great fun and deliciously disgusting. You can model the journey of food from the mouth all the way through the body!
Make a Snot Trap
Learn about the clever properties of snot and how it filters bacteria and other particles with this snot coloured oobleck!
Find out what dinosaurs ate by making dinosaur poo!
Find out why food rots and how you can slow the process down.
Kids Activities Blog tried making my ear wax snacks from Gross Science and they came out great!
Gross Science Experiments – THE BOOK
For even more Gross Science ideas check out my hilariously disgusting book with SIXTY icky, smelly, scary and downright silly gross science experiments!
Whether you want to discover the funny things a body does or the ghastly creatures all around you, there’s always something new to learn. Travel back in time to find out how people tried to mask the awful smells of the time, how the Romans wiped their bottoms and and even how a famous person’s body exploded! Discover what makes your breath so smelly, why stinky foods taste better when you hold your breath and make your own edible ( but very realistic looking ) poo.
Try an easy, exciting dissection with a homemade model of a brain or heart. Make decorations from milk or take a terrifying bath with the Bug Bath Bomb. This collection fun yet revolting activities is perfect for learning about the world in a hands-on sometimes delicious and sometimes disgusting way.
