Another fun science day with Mr. K from Exordium Adventure involved milk and eggs. Not as tasty as you might imagine and nowhere near as yummy as the Candy Science class. ;)
Science equipment provided.Xav crushed some egg shell with a large bolt in a small tin dish. Science equipment can be found anywhere.Vinegar made the crushed shell bubble just like it made the baking soda bubble (see naked egg below).Mal took a short break.Spinning an egg to see if it's cooked or raw. Raw eggs wobble.Eggs of various ages to show the buoyancy of fresh eggs vs. old eggs. Fresh eggs sink. The older eggs float because of air trapped in the shell.
Naked eggs (made by soaking the shell off in vinegar) are rubbery and bounce. But be careful! They break.Water tension that kept this water from running out of the cap.Milk and food coloring.If I remember right, we added dish soap and got this reaction.
Ever attentive students. HA! That almost hurt to type! hee hee.
