Date lesson taught: Monday, February 6, 2012 Subject: Science ALCOS Standard: 2.5 Lesson Objective: Lesson 5 TSW observe and describe the characteristics of plants in freshwater environments. Procedures: TTW say, “Today we will be looking at 2 plants that live in freshwater. Freshwater is rivers, streams, ponds, creeks-not the ocean. They are called Elodea and Cabomba.” TTW distribute sheet Observing Freshwater Plants. You will draw what you see and write a sentence about what you observed. When you are finished, place this in your science journal. Distinguish which plant is elodea and which one is cabomba. Distribute aquariums, paper towels, and hand lenses. TTW say, “If you pick up the plant to get a closer look, be sure to hold it over the water so it won’t drip on your desks.” Make a class chart of how freshwater plants are alike and how they are different. Add to science bulletin board. Elodea grows in slow-moving streams, ponds, and backwaters. Small organisms sometime live in its leaves. Fish eat this plant. It can grow up to 2 feet long. It can float freely or take root. Even if you break the plant apart, it can still grow and make its own roots. The plant produces oxygen, which you may see as bubbles. It has pointed leaves arranged around the stem in tight whorls of 3 or more. Cabomba grows naturally in streams and ponds. It flourishes in the light. It can float freely or take root. It is longstemmed with small branches of find leaves. Materials: Observing Freshwater Plants recording sheet (19), science journals, aquariums, paper towels, hand lenses, chart paper Assessment: Observations of freshwater plants-did they write a sentence and draw a picture for each? Accommodations: If a student does not have time to complete this activity, they will finish it for morning work on the following day. Modifications: No students in this class are on IEP.
