Block Class #5

This week my class used two liter soda bottles to make a water filter. We cut the bottle in half then we inverted the top to make it look like a funnel. We put the top in the other half and filled it with various things on the inverted top such as cotton balls, sand, gravel, charcoal, paper towels, and soil. Not everyones filter worked I think only one persons made the water clear we put oil and food coloring in the water. This will be the last block class for I think a month.
