yesterday we started studying africa. i'm shocked at how much i don't know about stuff. and i'm a pretty smart cookie. we used a map and the internet and just had a great time. i did make him do some boring stuff like labeling a blank map but for the most part we had fun. and we learned about apartheid in south africa. man. what is wrong with people? i just can't understand why some folks think they have the right to dictate how others should live. boggles the mind. big c was floored to think stuff like that happens. really opened his eyes.
anyway if you were wondering about the WW pix yesterday, we were doing a project on viscosity. Viscosity is a measure of the resistance of a fluid to being deformed by either shear stress or extensional stress. It is commonly perceived as "thickness", or resistance to flow. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a lower viscosity, while vegetable oil is "thick" having a higher viscosity. (wikipedia definition) and so if you add green food coloring and an army man you have a fun homeschooling project!! (we used corn syrup)
