Science Lesson Plan

Grade Level: 5th

Area: Physical Science- Density

Objectives:
Students will prepare litmus strips from red cabbage juice. With their strips they will test 5 household liquids for the color change the liquid produces on the indicator strip. Students will combine these results into a class chart.

Materials:
Small red cabbage, coffee filters water, baggies, lemon juice, baking soda

Set:
Today we are going to make indicator strips out of red cabbage juice. Once
these strips are dried, we will test different solutions and their
reactions with the test strips. These reactions will help us determine the
pH of a solution. We will then compare the reactions to a pH chart
provided. First, let's get our indicator strips ready.

Procedure:
To make indicator strips, tear small (very small) pieces of red cabbage and put into baggie. Crush with a rolling pin. Add a small amount ( 1 or 2 tbsps) of water and mix thoroughly. Next, take a paper coffee......
