Tomorrow is the big cookie showdown at work. Tonight I finally sat down to imagine how to gather people’s feedback about the cookies. I reviewed a bunch of rubrics and score cards, and created a Google Form, drawing from some examples online. When I shared it with the office folks, I received some interestingly heated responses… Continue reading What makes a fair test? Validity, reliability, and replicability in cookies.
Failure is a part of science, and figuring out what goes wrong is an important piece too. I kept some of the dough from last night’s cookie baking and tried baking them again tonight. It turns out that I was cooking them at the wrong temperature. I was using 375 degrees F (that’s what my recipe… Continue reading Chocolate chip cookie follow up
The goal here is to test a few different recipes for an upcoming bake off. How can two cookie recipes be so different? It’s all chemistry, I suppose. I’ve been making cookies one way for a while and decided to try a different way to see if they would be better. The results are so… Continue reading Top secret – ok maybe not so much 😋

So many consonants in Icelandic words!), one day driving the south coast until just before Vik, and went to the Blue Lagoon the final morning before flying home.
In the World of Wonder, Iceland is a wonderful place. 🙂
Here’s a presentation I did on science as a tool to wonder with for the Scheller Teacher Education Program (STEP) lab lunch in April 2017. Enjoy! Tools to wonder with….
My water pitcher has been my muse again! This time it’s because I left it out on the counter and came back to find bubbles. So I wondered – what would happen to the bubbles if I put the pitcher back into the frig? Would they dissolve? Think about this for a moment…. what is… Continue reading Bubbles in water
It started last December. I put some orange wedges and cranberries into a glass pitcher of water and put it into the refrigerator for a special Christmas lunch. Their dad dropped the boys off, and when the three of us sat down to eat, something miraculous happened. My boys bypassed juice options to drink the fancy… Continue reading Swimming citrus
