Students will create 3 jars of artificial pond water, collect data on their physical and chemical properties, and compare them to Pinelands water data. Students will be able to distinguish between a physical and a chemical property.

Through discussion, draw a distinction for students between a physical and a chemical property (characteristic) of water.
Set up 3 pint size jars of artificial pond water with your students using these recipes:
Direct students in small groups to use their senses, thermometers and pH or litmus paper to collect data and complete the "Pinelands Water Properties" student data sheet.
When all data has been collected, review the results with students.
Using the information on the student data sheet, relate the results to conditions of Pinelands surface water as shown on the "Properties of Pinelands Water" handout (if you are able to get a sample of Pinelands water, repeat the above tests and analyze and compare the results).
Check to see that the data collected by students is consistent and accurate. Question to see that the students understand the distinction between physical and chemical properties.
1. Plan a trip to the Pinelands and conduct some physical and chemical tests on various bodies of water. You will need to obtain water test kits from a scientific supply house to test for the conditions you wish to investigate. As an investigation of the physical characteristics of Pinelands water, you might wish to test the speed of Pinelands streams, especially in the area of an old mill, where you might speculate on the water's role in industrial development.
This lesson will introduce the students to the following vocabulary words:
