This week the ladies of Zavala Elementary explored soil and its characteristics. 5 different types of soil were closely examined by observing and recording its texture, color, and shape. I asked each girl to share something unique they discovered throughout the experiment and collectively we created a result chart. The chart illustrated the differences found among the common sediment or as one girl interpreted, “it’s all soil from the earth but comes in different colors, like people”.

This week the ladies of McBee Elementary learned about water pollution and ways to reverse its effects. We learned about different water pollutants in small groups, and then demonstrated some of these effects on glasses of water. Since each group was now stuck with a soiled glass of water containing dirt, soap and trash, we put our thinking skills to the test and created filter systems. What great engineers!

It’s cold enough outside to freeze water, so why not do a freezing experiment! We tested the effects of 3 different solvents reactions to the outdoor freezing temps (it was 25°F outside when we tested) and compared it one plain water sample. The purpose of this experiment is to test the freezing temperature of each solvent.  Food coloring was added for differentiation but had no impact on the freezing effect.
