The ultimate lunchbox! A Polymer packages competition for Primary schools The British Science Association’s CREST Star team and the Worshipful Company of Horners have launched a new competition to challenge primary school students to research and design the ultimate lunchbox... The challenge The scientists at Horners are really fed up of eating squished sandwiches that leak in their bags. They love finding new ways to use polymers, and want you to design the ultimate package, using polymers, to protect their lunch (and their bags!) on the way to work. What to do Research the kinds of things that people use to wrap up their lunches. (The ‘protecting polymers’ CREST Star activity is a great place to start.) Find out about different materials you might use to make your ultimate lunchbox package. You might want to think about: How heavy /bulky/strong/flexible the materials are Using different materials inside and outside the package How easy it is to clean/reuse/recycle the materials you use Design your ultimate lunch box. Share your idea: write about/draw/make/video your idea and send it to us. Don’t forget, if you do an experiment as part of your research, let us know what you found out. How to enter Entries are open to all primary-aged UK students. We have extended the deadline until 4 May 2015! Please clearly label the entry with your name, school (if appropriate) and age.If you want to submit a video, please send a link to the video online rather than sending the whole file via email.Email your competition design entries to: firstname.lastname@example.org or send them to us at:CREST Star Horners Competition, British Science Association, Wellcome Wolfson Building, 165 Queens Gate, London, SW7 5HD Prizes Prize packs for the top three entries will include: £25 Curious Minds student voucher; science goody bag worth at least £15; £50 TIMSTAR voucher for the school; CREST Star school membership (usual cost £40) and educator membership (usual cost £25) of the British Science Association. More competitions and prize draws! We’ve lots more ways for primary and secondary schools as well as other youth clubs and community groups to get involved in competitions and prize draws and citizen science activities during British Science Week.
