What happens when science gets messy, slimy, explosive, and a little disgusting?
Kids love it.
Horrible Science Experiments is a wildly fun, hands-on science course designed to capture children's natural fascination with the weird, the gross, and the fascinating parts of science. Instead of memorizing facts from a textbook, students dive into real experiments that make science unforgettable.
In this 15-week course, young scientists explore the incredible systems of the human body, strange chemical reactions, explosive earth science, and the mysterious world of decomposition through experiments they can see, touch, and investigate.
Students will make fake blood, create slime and non-Newtonian fluids, build erupting volcanoes, observe mold growth, simulate stomach digestion, and discover how their own bodies work in surprising ways. The "gross factor" becomes a powerful tool that makes scientific concepts stick. horrible-science-curriculum
Each class encourages curiosity, experimentation, observation, and scientific thinking while keeping students engaged with experiments they will talk about long after class ends.
Throughout the semester students will investigate five fascinating science themes:
Bloody Biology
Make realistic model blood
Discover how the heart pumps
Learn how blood clots and circulates through the body
Slimy Substances
Create oobleck and slime
Explore polymers and strange fluids
Learn why our bodies produce mucus and other protective substances
Explosive Earth
Build erupting volcano models
Explore earthquakes and tectonic plates
Discover the rock cycle
Disgusting Decomposition
Observe composting in action
Grow and study mold
Learn how nature recycles everything
Gruesome Guts
Simulate stomach acid digestion
Follow food through the digestive system
Discover how the body absorbs nutrients
✔ Hands-on experiments every class
✔ Designed for mixed-age homeschool groups
✔ Encourages curiosity, observation, and questioning
✔ Science journals help students think like real scientists
✔ Experiments use mostly inexpensive household materials
✔ A semester-long journey through biology, chemistry, and earth science
Length: 15 Weeks
Ages: 5–11 (adaptable for mixed ages)
Class Style: Facilitator-led, experiment-based learning
Students keep a science journal where they draw, record observations, make predictions, and reflect on what they discover.
The course concludes with a Science Showcase, where students demonstrate their favorite experiment and share what they learned with family and friends.
Expect slime, bubbles, strange smells, surprising reactions, and lots of laughter.
The best science learning happens when kids are curious, hands-on, and not afraid to ask the weird questions.
If your child loves experiments that are a little gross, a little surprising, and incredibly memorable, Horrible Science Experiments will quickly become their favorite class of the semester.
