Spooky Science - Scary Good Ideas for Your Class | Halloween 2025 Science
It's that time of year when Jack-o'-lanterns glow on every porch and students buzz with excitement about their Halloween costumes. While the holiday energy is at its peak, why not channel that enthusiasm into unforgettable learning experiences? We've crafted three spine-tingling, standards-aligned science activities that perfectly blend Halloween fun with serious educational value.

🧟 Zombie Ants: Nature's Biology Horror Story
Introduce students to one of nature's most fascinating and frightening phenomena with our Zombie Ants reading comprehension activity. This real-life science horror story explores how the Ophiocordyceps unilateralis fungus takes complete control of carpenter ants, forcing them to become unwitting hosts. Students discover:
- Parasitic relationships in ecosystems
- Behavioral manipulation at the cellular level
- Microhabitats and environmental conditions
- Food chains and population dynamics
This compelling narrative demonstrates that truth is often stranger (and scarier) than fiction while teaching crucial biology concepts about symbiotic relationships and ecosystem interactions.

🎃 Puking Pumpkins: Chemistry Gets Messy
Transform your classroom into a bubbling laboratory with our Puking Pumpkins chemistry experiment! Students explore the rapid decomposition of hydrogen peroxide catalyzed by yeast enzymes, creating dramatic foaming reactions that erupt from carved pumpkins. This hands-on demonstration teaches:
- Chemical reactions and decomposition
- The role of catalysts and enzymes
- Exothermic reactions
- The scientific method through experimentation
The colorful foam "vomiting" from pumpkins creates an unforgettable visual that helps students understand molecular-level chemistry while having an absolute blast.

🕷️ Creepy Crawlies Challenge: Physics in Action
Get students engineering with our Creepy Crawlies Physics Design Challenge! In this engaging activity, students design and build tools using simple machines to transfer plastic bugs from one bucket to another—without using their hands. This challenge covers:
- Six types of simple machines (levers, pulleys, wedges, and more)
- Mechanical advantage calculations
- Engineering design process
- Force, friction, and motion concepts
With only 15 minutes to build and 30 seconds to compete, students learn to think critically about efficiency, reliability, and practical physics applications.
