1. Demonstrate an understanding that a cell is the basic unit of living organisms.	Demonstrate correct use of microscope. Draw and label observations.			Students will observe a variety of cells through a microscope and draw and label their observations. Students will diagram and label a plant and animal cell.	Students will be able to explain how they know that a cell is a basic unit of living organisms.	nucleus cytoplasm membranes cell chloroplast cell membrane cell wall plant animal
2. Describe how single celled organisms exist.	Bacteria & fungi are one-celled organisms. One-celled animals break down & absorb nutrients from other plants & animals.

3. Explore how the use of a microscope allows one to see cells in a variety of organisms.	Use of microscope: place slide appropriately position for adequate light focus lens for clear viewing			Students will use a microscope to observe a variety of plant and animal matter. Maine LAD task: Seeing Cells (also J1, Inquiry and Problem Solving and/or M1 , Implications of Science and Technology)	Students demonstrate basic ability to use a microscope.	lens slide light focus
4. Describe the functions of the major human organ systems.	Skin Digestive system Circulatory system Respiratory system Muscular system Skeletal system			Students will create a model of the respiratory system. Students will create a life size pattern of themselves and place organs in their appropriate places.	Given a diagram of a body system, students will identify the system and explain its functions.	muscular respiratory skeletal digestive circulatory nervous| skin systems organ nerve cells tissue
