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.
Today students found out what happens when you mix baking soda and vinegar...a gas is formed! Such a fun way to teach that a gas does take up space and has weight!
Today we completed the final stage of getting our Building License with the LEGO Learn to Learn building sets. After building Learnie to make sure we had our pieces, we brainstormed guidelines for successful building. Then all students used the same 8 bricks to build a duck anyway they wanted. The students were amazed at how many ways the ducks could be built, and really got the point of the lesson...that everyone is unique and there is more than one way to build. Finally students had time to build any creation they wanted.
This week we continued to study about the states of matter. One of the things we did was to attempt to make ice cream in a bag. Only 4 students got the ice cream to freeze in the bag! But if Thomas Edison can say, "I have not failed. I've just found 10,000 ways that won't work," so can we. We froze the bags in the freezer. The next day it was, "Uh, oh! Too hard to eat!" Finally, on Friday, we set the bags out for a while and kneaded them to "just right" consistency. Yum!
As part of our current math unit on geometry, students were challenged to find 2D faces on 3D shapes around school. Thanks to parent volunteer Mr. Mitchell for taking small groups on a scavenger hunt around school and capturing their findings on camera. Can you guess what shapes the students are standing near or pointing at?
This week we started a new math unit on geometry. During the week students made 3-D shapes from nets including cylinders, rectangular prisms, triangular prisms, cubes, and pyramids. During STEM time we took our 3-D shapes and turned them into sculptures, creatures, and buildings. Check them out! How creative! Definitely adding the A-for Art to the STEM to make STEAM! PS: It was School Picture Day! Don't the kids look especially nice!!
