Squishy circuits

20160127_143906

20160127_144008I recently worked with two Y4 classes to introduce their new topic Electricity. We made some basic circuits and then used squishy circuits to investigate different ways of making circuits, different components and different ways to connect them up. They also had the opportunity to get creative with their squishy creations! I returned to the school a few weeks later and they’d made a fantastic display on what they’d learned so far

Painting with plants

Year 1 painting

Autumn is well and truly underway here in Durham and the leaves are turning beautiful shades of red, yellow and brown. Our painting with plants workshop covers a range of topics including: chemical reactions, identifying leaves and also getting creative with paints made from different plants.

More able or older children can go into more detail with labelling their drawings, and painting extra details on their leaves. Most of all it’s great fun and quite messy so the children love it!

The colours also match quite well with the changes in leaves during the Autumn so these leaves could form the basis of a Autumnal classroom display.

A scorching summer fair

Last weekend I ran a science stall at my daughter’s school summer fair. I would love for kids to think it normal to take part in fun science activities as well as win sweets and eat cakes!

The beads inside (no UV light)

This year, I had UV-sensitive beads for visitors to make into wrist-bands or bag charms. The beads change colour under UV light. It was a scorcher of a day so ideal for demonstrating the beads.

Light is made up of colours we can see (the colours of the rainbow) and some which we can’t (e.g. ultra-violet or UV light). These beads change colour in UV light. Inside they are clear as seen in the picture to the right.

Take them outside (or shine a UV light on them) and they change colour. Even on a cloudy day they change faintly. On a really sunny day the colours are bright as can be seen in the second picture below.

…and outside in bright sunlight

Too much UV light from the sun can give us sunburn and damage our skin. We used factor 30 sun cream to block the UV rays and prevent the beads from changing colour.
