Our amazing light photography
We had a lot of fun tonight experimenting with light and dark to create light paintings. With a slow shutter speed (between 15 and 25 seconds) on the camera in a dark classroom, we painted pictures with glowsticks and torches. We gradually learned that the slower we moved the clearer the image. Well done everyone who had a go tonight! Hope you like seeing some examples of your work.

Homework for Thursday 8th October
We had some fantastic inventions for spy equipment that would let you see round corners without being detected! We even had a complete periscope!
If you would like to find out how to make your own periscope, try the ideas here:
Planet Science – make your own periscope
If you don’t have small mirrors, you can try using pieces of old CDs, or sticking silver foil onto card and carefully polishing it smooth.

Can you see a white cat in the dark?
We did some good investigating this week with a white teddy bear and a dark cupboard to see whether we could see him in the dark. We started off thinking we might be able to see his sparkling eyes, or his white face and paws (- most of us thought we wouldn’t see his dark jumper), but we discovered that, without a light source, we could see nothing at all!
We have discovered that the only reason eyes shine at night is that there is still some light at night that is reflecting from them. So, if it really is completely dark, just like the teddy bear, we would not be able to see a cat’s eyes.
