Posting Letters

Earlier this week we carried out an investigation to help Mir's mum. She wanted to find out which material would be best for soaking up some water, so we tested a few materials to find out the answer. 

Once we'd got our results we thought we'd share them with all our mums and dads, so we wrote some letters to tell them what we'd found out. We put the letters in envelopes, found out our addresses from the school office (thank you Mr Farrell!), and invited some parents to walk to the letter box near our school with us. 

Thanks to the parents who were able to come with us - it made us feel much safer having so many helpful grown ups with us. Thanks also to the parents who've already let us know that they've received their letters. Feel free to write back to us - you can post letters to us at school or message us here or on Twitter - as we'd love to know what you think about our investigation. 

Which material would be best to soak up a spillage?

On Monday we got a Twitter message from Mir's Mum. She knew we were learning about materials and wanted us to help her with a problem: she spilled some water while she was watering her plants and wondered whether we could find out which material would be the best to soak it up.

We had a lot of fun (as well as practicing our Science investigation skills) finding out the answer, as you can hopefully see from our photos. Thanks to Miss Longley for helping us to think about how to make our test fair, teaching us how to measure and record our results properly, and encouraging us to use the word 'absorbent'.

Which material do you think soaked up water the best: foil; kitchen roll; cling film; a cloth; or a sponge? Come and ask us to tell you what we found out!
