A Photochemist investigates the chemical effects of light.  Photochemistry is a chemical reaction caused by absorption of ultraviolet, visible light or infrared radiation or a reaction that produces light. Photochemists may be interested in spectroscopy- splitting up light into it’s different colours to find out about the properties of the object being studied. They may be interested in photosynthesis, the way a plant generates energy from light. They may also study animals who use bioluminescence to signal to other animals or to lure prey.

Science for Families: Light

Things to try with your spectroscope, and more activities based around light.

Think Week 2015

Joe reports on our first Think Week summer school of science activities.

Giant Bubbles

Everyone loves soap bubbles. Most of us really love them. Particularly when they’re huge hovering things, hanging in the air or floating gently away.

Making large bubbles is easier than you might think. People argue endlessly over different soap mixtures (they’re a classic subject of after-dinner arguments conversation for science communicators), but standard household washing-up liquid is almost as good as even the finest formulations. The real trick is in the way you blow bubbles, as this film will show you.

This is another film from the Royal Institution’s ExpeRimental series, all of which are worth checking out.

We’ve written up an entire page about bubbles, including a beautiful way of viewing soap film colours.

Homemade lava lamp

You’ll find this activity all over the internet and in loads of science activity books, and this is a particularly nice film both illustrating it and exploring how you might use it as a family project. There’s plenty to discuss around around why some things float and others sink, and hence the concept of density.

This is another film from the Royal Institution’s excellent ExpeRimental series.
