How do microwaves heat up your coffee? Adjust the frequency and amplitude of microwaves. Watch water molecules rotating and bouncing around. View the microwave field as a wave, a single line of vectors, or the entire field.
Here is a collection of fun microwave experiments that are suitable for the classroom. Issue 12 : Summer 2009. Plasma balls. Using a microwave oven, you can create balls of plasmaw1 at school from nanoparticles of soot. Dr Chris Schrempp, who teaches at a Californian high school, has been doing this in class for some time.
This collection of microwave experiments for kids is a great way to get them interested in science and have fun in the kitchen. Not only do microwaves provide an easy way to heat food up quickly, but they can also be used to conduct exciting and educational experiments!
Microwave Properties. 10 cm microwaves are used for the demonstration of travelling and standing waves, reflection, interference, refraction, diffraction, absorption, polarization, tunneling, and waveguides.
Did you know that you can measure the speed of light using a microwave oven, some egg white, and a ruler? Find out how with this cool kitchen science project thanks to Mr. Nick Hood, a science teacher in Fife, Scotland.
