Hello Everyone!

I hope you are all keeping safe and well. I thought you might enjoy  some Science challenges!

Each week, I will post the latest challenge, it’s open to everyone. I’d love to see what you come up with.

So here is the first one…


We used my canopy to make a transparent den, light can passed through it and we can clearly see our facesYou can work with an adult, siblings or even by yourself! Once you’ve finished building it, see if any, light there is. Can you see your own hand in front of your face?

You will need:

A mix of building materials (garden canes, cardboard boxes, paper, net curtain, clear plastic, old sheets, foil, tape, glue, elastic bands, packaging and other bits of recycling). Whatever is handy really. We used a clothes horse, quilts, blankets, cushions and pegs in our house!

Background Science:  

Different materials let in different amounts of light, some materials are transparent, some are opaque and some are somewhere in between – translucent.  Bitesize Revision  explains transparency and opacity of materials further.

If you want to take a picture of your den to share on this page, ask an adult to send it FAO Mrs Byrne to

TIP: Start saving some newspapers and ice-cubes for future challenges!

Here’s our first entry from Hayley and Hayden, who say…

Me and my brother tried the lightproof den experiment And we had so much fun. We used my canopy to make a transparent den, light can pass through it and we can clearly see our faces. We used our toy boxes lids to make a Translucent den. We can still see our faces partially and some light still passed through it. Inside the opaque den we used the flash on our camera or else we can’t see anything 🙂

Wow! Excellent investigating Hayley and Hayden, I am so impressed! I love that you used your toy box covers to test too – very clever thinking. Great teamwork. A big air high-five from me to you both!
