Make science fun, festive, and hands-on this Halloween! This resource includes three engaging experiments that will get your middle school science students excited about chemistry, physics, and physical science. Each activity includes a description, a detailed procedure/material list, discussion questions (with answer key), and an optional rubric.

You can also find this activity at a discount inside my - Halloween Science Activities and Investigations Growing Bundle.

What’s included:

1. Pumpkin Oozing Slime Experiment (Chemical Reactions) – Students create a colorful “ooze” using baking soda, vinegar, and dish soap inside a pumpkin, observing bubbling and foam to understand chemical reactions and gas production.
2. Ghost Balloon Rockets (Force and Motion) – Students build and launch balloon “ghost rockets” to explore Newton’s third law, experimenting with balloon size and inflation to see how forces affect motion.
3. Glowing Monster Density Columns (Density and Buoyancy) – Students layer colored liquids to build glowing columns, exploring density differences and buoyancy while observing how liquids separate based on their properties.
   

Why students will love it:

• Each activity is hands-on, interactive, and visually exciting, making science fun and memorable.
• Activities tie directly into Halloween themes, adding a festive and creative twist to learning.
• Students can experiment, observe, and manipulate variables, encouraging curiosity and exploration.
  

Why teachers will love it:

• No-prep or minimal-prep activities with clear, step-by-step procedures.
• Includes discussion questions and rubrics to assess understanding and guide classroom conversations.
• Perfect for sub plans, Halloween week, or science centers, saving you time while keeping students engaged.
  

Learning benefits:

• Reinforces key science concepts such as chemical reactions, forces and motion, and density.
• Encourages critical thinking and scientific reasoning through observation and experimentation.
• Provides opportunities for hands-on learning, collaboration, and creativity, ensuring students not only see science in action but also understand the “why” behind it.
  

Bring Spooky Science to your classroom and watch your students get excited about learning science this Halloween!
