Dry Ice Crystal Ball Bubble – SICK Science | Experiments | Steve Spangler Science

It’s the world’s coolest crystal ball.

Create a soap film on the rim of a bucket and, with one other simple ingredient, you will have made the world’s coolest crystal ball.

Homemade Hand Warmer | Science Experiments | Steve Spangler Science

Here’s a twist on the classic chemical hand warmers you can buy for you to research and improve.

If you’ve been outdoors when it’s really cold, there’s a good chance you’ve either used these yourself or wished you had. You can experience a variation on the science found inside a commercial warmer with some pretty basic materials. You’ll discover how an everyday chemical reaction like rusting is used to keep your digits toasty. This experimental version of the hand warmer is offered as a test idea and not as a definitive solution. You’re encouraged to share your science fair results online.

Heat in the Environment Mini Unit Overview

by LOUISE VAILLANCOURT.

Can understanding particle theory and heat transfer modes help you build efficient devices to improve our daily lives?

Learning goal

  • Heat is a form of energy that can be transformed and transferred. These processes can be explained using particle theory of matter. (Big Idea 1 from curriculum document) (Overall expectations 2 and 3)

Over-arching Challenge

Design (or improve on a design) and build a solar oven that will cook food and sterilize water by applying knowledge of heat transfer by convection, conduction and radiation.

This project is part of the STAO Connex Series.  Click here for more details.
