Properties of Water

Today students had a reading quiz on section 2.2 and we learned about the properties of water.  In our seeds and salt experiment, we saw how plants take advantage of the cohesive and adhesive properties of water to take in water through their roots.  Many of us experienced evaporative cooling in class over the past few days.  If you go swimming in Lake Lugano or tubing at Lago Maggiore over the weekend, you'll be taking advantage of water's high specific heat (even though it has been cool at night, the lakes are still warm).  So even without realizing it, you benefit from the unique properties of water everyday.

There is no homework due Monday.  If you are unsure about the pH scale, click the picture below to link to an interactive pH scale.  Use the brown arrows in the lower left of the animation to navigate.  The interactive pH scale is on the third slide.
