Grade: 4
Subject: Science
Water Ecosystems
Two types of water ecosystems--freshwater and saltwater. Ex.Places--swamp, ocean, river
Key Vocabulary: Food web, food chain, consumer, producer, decomposers, omnivore, herbivore, carnivore, population, adaptation, ecosystem.

Expected Outcome Of This Lesson Plan-
1. Access prior knowledge of what a water ecosystem is by a.) connecting to self (what water ecosystem has she been to--i.e. lake, ocean, river, swamp--?)
2. Demonstrate understanding by describing a chosen animal's function (decomposer, producer, consumer) in it's own ecosystem
Teacher Objectives-
Purpose for reading: How does matter flow in ecosystems? (matter= minerals, oxygen, carbon dioxide)
Paper, glue, coloring materials
Teaching Methods-

1. Lesson Introduction-

1. Beginning reminder--this is a continuation of the lesson from last week on Ecosystems
2. The Earth is covered in almost 3/4 water--what does this tell us about how many water ecosystems there can be? Can you give examples?

2. Lesson Progression-

1. Review previous week's lesson on ecosystems
2. Introduce specific ecosystem to learn about today--water ecosystem
3. Utilize text and pictures in textbook, images on SMART Board and materials to make food web to enhance learning

3. Guided Practice-

1. Discuss water ecosystems
2. Create a food web
3. Break into small groups to practice vocabulary
4. When not working in a small group with a teacher the students will be reading to a partner about ecosystems or quizzing one another on the vocabulary words

4. Student Practice-

1. Each student will create a food web based on living beings in a water ecosystem

5. Learner Accommodations-

1. Visual Instruction (Images on SMART Board)
2. Oral Instructions
3. Hands-on activity
4. Repetition
5. Small group instruction

6. Assessment-

1. Teacher/student: questions/answer
2. Student demonstration of food chain and food web

7. Lesson Closure-

1. Tomorrow we will focus on Decomposers. Thought to consider: what effect do decomposers have on a food web?
Measuring Student Progress-
1. Each teacher works with a small group to check for understanding (vocabulary and concepts of the lesson).
2. Each teacher continuously monitors understand through conversation and observation of students
