We really have been enjoying the chemistry lessons, it seems each experiment gets just a bit more fun. The mess is getting a bit more as well, but clean up is manageable. We made our own acid base indicator from coffee filters and red cabbage! How cool is that? I know all you savvy home school moms out there have probably done this tons of times, but I was as excited as the kids that this actually works! We boiled red cabbage for about 20 minutes and let the resulting purple water cool to room temp. Next we wet some strips of coffee filter with the liquid and let that dry. Well, let me just tell you that dipping these little strips in our control base (ammonia) turned them green and the control acid (vinegar) turned bright pink!
We have a jar of left over cabbage liquid in the fridge that will be used for this weeks experiment as we start to talk about acid base neutralization and titration. Should be fun.
How was your week/weekend? Any fun science going on?
