I made ScienceFix.com to share my favorite demos that I do in my middle school science classes.

Video Tutorial: Isotopes


I purchased Camtasia Studio over the summer and have used it to create tutorials for teachers that use our school's gradebook program.  I just discovered a feature in the software that allows quizzes to be embedded in a video.  I create Power Points all the time that are designed as mini tutorial/review sessions for my students.  Camtasia has a plugin for Power Point that allows you to capture screen video and audio.  So I decided to do a screencast for my isotope review/tutorial and then embed questions that students can answer to check their understanding.  I'm very pleased with the results.  I think I might do screencasts in the future for subs to run during an absence. It will be like I'm in the classroom, when I'm not.


Video Demo: Expanding Soap

Ivory soap has air whipped into it during the manufacturing process, creating tiny holes with minuscule water droplets inside.  When microwaves hit the water, it vaporizes and expands it, causing the bar of Ivory soap to expand.  

Video Demo: Phases of Matter Models

The particles (molecules) of a solid, liquid, and gas act differently because they have different energies.  The video shows how to model those differences to students.


Video Demo: Newton's 3rd Law

A simple demonstration of Newton's 3rd law of motion in action.  A rubber band under tension is cut, launching both the sled and the launching mechanism in equal and opposite directions.


Video Demo: Adding Forces

This is a fun and easy demo to teach what happens to objects when forces are acting in the same direction.  A series of balls are dropped together, one on top of another. The forces are added together, creating a larger force that propels the top ball to a much greater height.
