Y6 grow microbes

In science year 6 have been investigating microbes. We found all sorts of microbes lurking around school. We used cotton buds to swab handles, bannisters, pond water, specs, etc and pressed the buds onto plates of agar jelly. We left one section of the plate with nothing added. This was our ‘control’ and acted as a comparison.

Here are our plates of nutrient agar after two weeks.

Yuk!

Now you know why were always on at you to wash your hands before tea!

Dry Ice Fun on Open Day

Year 6 (and some parents and visitors) had a dry ice demonstration by Mrs Angell and then got a chance to have a go themselves. We learned that dry ice is solid carbon dioxide and is desperate to get back to being a gas – which is does with interesting effects, like making floating fog, pouring clouds, screaming spoons, giant bubbles and soap monsters. Here we are at work. (OK, play.)

8DP finish off the dry ice in the last lesson of the day. Four dry ice demos today and Mrs Angell needs a strong cup of tea! (Will somebody take my prep tonight?!)

Year 7 generate their own electricity

Year 7 are coming to the end of a topic on renewable energy resources, and today we found out how generators actually work. We know that turbines drive generators to make electricity, but how?

Its all about magnets and coils of wire. Did you know that if you move  a magnet near a wire you can make the electrons in the wire move – and moving electrons = electricity! So that’s what we did. We moved magnets inside coils. We tried big and small magnets, thick and thick wire, lots of coils, coils round things, bare coils… and we measured how many milliamps of electricity we could generate. The winners were  Tom, Rebecca and Izzy, with a massive (OK, modest) 0.47 milliamps of current. Here they are working on their challenge.
