I’ve mentioned previously abotu the time my boys got curious about why I fussed so about the electric bill, and we ended up with a project where the electricity usage of individual appliances got measured.
I’ve noticed, lately, my boys getting really curious about acids and bases. I haven’t yet discerned the cause of this interest, but the questions keep coming up. I answer them as we go along, making conversation, but then I realize that this prompts questions in my own mind – (to my kids) Did you know that vinegar is acid? Not pure acid, but still. Lemon juice, too.
And then we talk about baking soda, and how chemical leavenings work, compared to yeast leavening (food is always a guarantee for keeping their attention…).
Here’s a round up of some learning activities and resources that kids (mine and yours) can use to exlore pH (acids and bases) in the world around them
- What does pH stand for?
- How Do You Measure the pH of a Solution? This article talks about using test strips, but it may be simpler, and more interesting to kids to use a pH tester like this one.
- A list of science fair project ideas, broken down by suggested grade level
- This link goes to a website some students used to document their science project measuring pH. I enjoyed reading it, and I think it would be interesting to other kids, too.
- Fun Science Gallery has a list here of experiments with acids and bases.
- Getting back to the kitchen, acids and bases are really important in areas other than baking.
- Make kombucha with your kids (read about acidity here and here)
- Make water kefir with your kids (click here to read more)
- Make vinegar with your kids. I remember reading about making apple cider viengar in a cookbook inspired by the Little House books – it was really inspiring. Read about safe home food vinegar production here.
I hope this gives you some great ideas for some fun and interesting learning in your home.
The Rozway Digital pH Meter comes with everything you need to get started – whether you’re testing nutrient fluid for #hydroponics or just running some #homeschool #science experiments. With it’s easy to read display and simple structure, your students will be up and using in no time flat.
