Fantastic work by all the team in #downendscienceclub. We have turned our derelict pond into the beginnings of a bog garden. Loads of hard work shifting soil and rubbish! Great team work. @lisaj_howell @DownendschNews

Try the Practical Action Wind Turbine challenge and learn about the use of turbines in Peru for people living in rural mountain areas. https://t.co/rBhgyEC5Ce Imagine life without mains electricity. How would you power your home?π¬ #DownendScienceClub
And here is a challenge for the summer holiday: design and build a wind turbine. Can you use it to pull up a weight on a string? Or attach a motor and try to light an LED. How many blades is best? What dimensions? Do blades need to be tilted?π¬#DownendScienceClub @MrGWilliams4
Make biodegradeable caesin plastic using milk. Warm 1/2 pint full fat or semi milk. Add 1 tablespoon white/clear vinegar. Stir. Watch it curdle. Sieve the curds. Squeeze and dry on paper towel. Shape in pastry cutters or by hand. Dry for 3-10 days. Decorate. π§ͺ#DownendScienceClub
Our final pH indicator experiment: Try adding acid (lemon juice/citric acid or vinegar) and alkali (bicarbonate of soda or soap) to a solution of Turmeric powder mixed in a little water. Wait a few minutes. Observe the beautiful yellow and red colours. π #DownendScienceClub
π¨π§ͺFizzy Art: Experiment with mixing bicarbonate of soda into your paints. Create your picture and then spray or paint over with lemon juice or vinegar. Watch the neutralisation reaction happen and observe the effects on your art work. @DownendART π¬ #DownendScienceClub
More magic art π¨using a base of red cabbage water on paper. Beautiful pastel colours appear when soap, lemon juice and vinegar are used to paint over the paper. @DownendART π¬ #DownendScienceClub
Use your red cabbage indicator water to create some magic art π¨ @DownendART Paint your paper with the cabbage water. Dry. Then paint over using vinegar, lemon juice, soap etc. Watch the different colours appear!

Red cabbage indicators! Test substances: are they acid or alkali? Chop up, mix in warm water. Add vinegar (acid) or bicarbonate of soda (alkali) and observe.π Test hand soap or other products. SAFETY: Do not use cleaning products. Can you make a rainbow? π #DownendScienceClub
And what better time to start our online club than STEM clubs week. Watch out for lots of activities you can join in with. π¬ #DownendScienceClub
