Eggsperiment

We soaked raw eggs in jars of vinegar to see how the acid dissolves the eggshells. The kids added blue food coloring for fun. After 2 days, the eggshells were completely dissolved yet the eggs were still there in their normal form, held together by the membrane! The eggs were blue, slippery and slimy yet contained and seemed a little bloated. When Ezra broke the membrane, the raw egg splattered. The blue food coloring and the vinegar had seeped inside. It stunk! The membrane looked and felt similar to that of a balloon. Ezra wants to try this same experiment using coca-cola next.

Another simple yet fun science experiment!

Brownies and Beading

We crafted and baked with Jonna again this week. She and Esperanza made Mexican brownies and then she got started on teaching us how to do some bead work!

Bloody Science Lesson

Today's science lesson was inspired by a 'don't-try'this-at-home' accidental science experiment that happened yesterday. Ezra cut his finger pretty badly - no urgent care or stitches involved thanks to the very clever butterfly bandage some genius invented. There was, however, a lot of blood, tears and a broken piggy bank. Today, we used that experience to discuss The Circulatory System! The kids were pretty bummed when I told them that we would be sitting down reading some books for science today, but they quickly became interested once they realized it related to the blood that was everywhere yesterday. Learning that the blood came as a result of a blood vessel being cut, then how with the combined help from the platelets and red blood cells a clot was formed to stop the bleeding was pretty fascinating. And then there was more reading about the heart, veins, arteries, capillaries and other bloody stuff. Then we drew some art on the chalk wall! This is how we do school in our house. We learn by living. This is also why I have 150+ checked out library books at any given time...ya never know what we might want to look u and learn about.
