Today was Book Character Day at our school, AKA Halloween. Look at these great costumes! The 2nd grade teachers dressed up, too, as different characters from the most popular 2nd grade book series, The Magic Tree House. For our fall party we made ghost lollipops and frosted and decorated cookies while listening to Pandora's Halloween Party Radio. We did have some great healthy treats, too. Thanks, parents, for the treats and craft supplies and thanks to the parents who helped out!
Is it a solid? Is it a liquid? No, it's Oobleck, a type of colloid that is somewhere in between. We could squeeze it into a ball and bounce it, yet it oozed like glue. Each year when I do this it makes such a mess I think about not doing it, but the kids love it sooo much, I can't give it up. Here is the lab sheet we used.
We have been exploring symmetry all around us this week in math, including building symmetrical structures with one line of symmetry using 10 or more blocks. I think we have some future architects among us!
Today we made bread twice! What? Twice? Yes, after everyone had a part in measuring the ingredients into the bread maker, we discovered the machine had bit the dust...and it had worked perfectly the day before for Ms. L's class! Fortunately Caroline's mom came to our rescue and brought us her machine and we started all over again, just in time. 3 hours later, as we drove the rest of the school crazy with the wonderful aroma of bread baking, we had bread. Then, while we watched, Magic School Bus, Ready, Set, Dough, the kids passed around a Mason jar with heavy whipping cream and made butter. Yummy! Another Incredible, Edible, Science Day!
Today we made Jello to see, feel, and TASTE a colloid, something between a liquid and a solid. We used the Jell-o Jigglers Recipe so that the students could pick up the piece with their fingers before eating it. Incredible, edible, science! Click here for the recipe.
