As I promised last year when I started this blog, uni would take over my life and I would neglect it. I’m hoping to make up for it with a lot of posts tonight but no promises!
In November I ran the science investigator badge for 12 of the girls. This post may become redundant with the new programme incoming but oh well, I’m writing it anyway.
Because I am currently not in the same room as my badge plans, I’m doing this from memory but shall try to do it as well as possible. Most of my meetings filled an hour, as we spent half an hour singing ready for our visit to the care home for Christmas.
Week 1: Spaghetti and Marshmallow towers (Easy, cheap, and the girls loved them!), and then we made cress in yogurt pots. It was easier to transport than eggshells, and I don’t even like eggs. The effect wasn’t as good but the girls seemed happy decorating the pots with tissue paper and feathers. Overall, it was a good night.
Week 2: Slime. Need I say more? I only planned to do this badge so they could make slime, as they’ve been asking for ages. It took 5 attempts to get a working recipe, but I promised slime so I wasn’t going to give up. Eventually I determined the optimum recipe was PVA glue, a small amount of bicarbonate of soda (out of date works fine!) and slowly adding contact lens solution until it comes away from the sides of the pot. Food colouring can be added if you want to make it colourful, I’m sure glitter or other things could be too. They absolutely loved it! Was definitely worth the utter stress to see them enjoying their slime. Suddenly they weren’t so bored with the idea of doing science!
Week 3: Space. I needed a filler week, so we made straw rockets (template, you put a piece of a big straw on the back, and then put a smaller straw in it and blow. Relays down the hall is great fun!) The small straws were normal ones, I may have borrowed 6 wider straws from McDonalds for the big back ones and cut them in half. I looked very sad eating alone with a large amount of straws! We also did a space quiz, because space is cool, and I also made it about famous people who did things with space. A lot of the girls thought Louis Armstrong went to the moon!!
Week 4: Indicators. We made red cabbage indicators (I nicked the flat’s kettle, and hoped they wouldn’t want a cup of tea for a couple of hours, oh the woes of a student house), and tested loads of things for acid and alkali. Each girl had a different thing to add to the solution, such as lemon juice, soap, berocca, washing up liquid, coke, vinegar, laundry powder, fabric conditioner, and a couple of other things I found in the house. They absolutely loved seeing the colour change, and I like to think I taught them a bit about acids being sharp and alkalis being soapy. It was a really great activity and I’m glad they enjoyed the badge. Below is my experiment at home before I decided to do the indicator – if there’s one thing I know about science its that you need to make sure it works before you try to impress people!
