Strawberry DNA + Cheese

Two separate activities, of course. Homeschooling goes on, amidst everything else, and I’d like to report on what N is doing more frequently but, well, many things have fallen off the list here, replaced with super fun activities like cleaning and clearing all the things. It’s more of a priority to do the activities than blog about them, obviously. But I wanted to share some things from this week and lo! I have managed to.

Firstly, he is working through his chosen science curriculum, REAL Science Odyssey Level 2. It’s a challenge–this is definitely not just a review of things he already knows. Depending on the material, I have us cover a chapter in two weeks instead of one, so we’re just now starting Chapter 7, which introduces DNA. In one of my decluttering sweeps I found instructions for extracting DNA from strawberries, which we picked up years ago at an open house event at URI’s Graduate School of Oceanography. You can find lots of instructions online for this if you search. I like URI’s handout because the measurements are scientific and precise–in milliliters and grams–and it explains the why behind each step. The only thing I had to go out and buy was pineapple juice.

The DNA is that cloudy stuff right at the spot where the clear liquid (cold rubbing alcohol) and the pink liquid (strawberry mixture) meet. Here’s a close-up.

How cool is that?? So cool. Then we fished it out with a toothpick and looked at it under the microscope. You can’t see the double helix, of course, but it’s still so cool.

Earlier this week, he made cheese. Just about a year ago, he made his first couple of batches, and then…lost interest. He asked to do it again recently, and chose a dessert ricotta. The recipe called for citric acid powder, which we finally tracked down at the local Ace Hardware after striking out in all grocery stores we tried. The cheese was fantastic.

We realized we needed something to eat it with, so we made cake. The next day I made ricotta cookies. We still have about half a pound of ricotta left, so I think I’ll make more ricotta cookies. This is a yummy project.

And one final thing related to homeschooling…the latest issue of Home/School/Life Magazine is out; my column is full of tips to make visiting an art museum with young kids fun for everybody. You can subscribe or buy a single issue of the magazine here, or try to win a copy at Mud Puddles to Meteors.

    My husband experiments with making cheese and gets his hard-to-find supplies online from cheesemaking.com – their ingredients and directions make great cheese! (Except don’t add liquid smoke to mozzarella – that was an experiment and totally screwed up the cheese.)

    That is SO cool!
    I might have to check out that curriculum. I think the kids might enjoy a *real* science curriculum at this stage of homeschooling.
    The cheese looks super yummy!
