It's almost soil time! Students get tricked on questions about retention of water by soil all the time. The best way to help them understand is to use the vocabulary while testing the capacity to retain water themselves!
This activity includes 3 student recording sheets that can be glued in their science notebooks. Students record observations in pictures and words, calculate the amount of water retained by the soil samples, create a chart and graph of their data, write a conclusion, and determine what would increase the reliability of the experiment.
I hope this helps you plan your soil unit! Find this freebie at my blog!
