Contrails are vaporized water that condenses. Condensation is a process by which water vapor is cooled resulting in the […]

Mixtures:Snow Ice Cream
1. I am always amazed when a person announces that they don’t like science, and chemistry was not their favorite class in school. The problem is that they just don’t see the whole picture. Fist of all, chemistry is about everything that most people love and enjoy way too often–FOOD! Let’s have a bit of […]
Analyzing Data: Graphing
The diagram shows the set up for a science investigation in which the temperature of two containers is to be compared. The two jars are identical, except the one on the left is covered with plastic food wrap. Readings from the thermometers in each jar will be recorded every ten minutes for a total of […]
Mechanical Waves
A mechanical wave is the transfer of energy through a medium (any material through a wave can travel). Please note that it is energy that is moving and not the material through which the energy travels. For example, the diagram shows how one wave of energy moves though water. Each colored dot represent one water […]
Converstion Factors
I’ve had to really dust off a few brain cells lately. Well maybe I should say that My few brain cells needed much dusting. When I taught physics, stuff about conversion factors was easy for me, but I’ve been working on basic experiments for kids for some time now. Young learners are not ready for […]
