Description
Background: A cell is the basic unit of living things. It is the smallest unit of life. Basic understanding of unicellular vs. multi-cellular. Knowledge of structure and functions of cell organelles. Molecules are constantly moving. They move in a straight line unless deflected by other molecules. Diffusion is the process by which the collisions between molecules cause them to continually spread apart from each other. Their overall movement can therefore be described as movement from an area of high to low concentration. Osmosis is a special type of diffusion. It is the diffusion of water across a membrane.
Essential Question:
o How does concentration of liquids affect molecules diffusing through membranes?
Objectives:
· Students will work cooperatively in small lab groups.
· Students understand and practice lab safety procedures.
· Students know the meanings of microscopic vocabulary and can identify parts of the microscope and mastered microscopy usage.
· Students will create a “cell” and experiment with Diffusion through its membrane.
· Students will test for the presence of starch and glucose in samples and be able to differentiate between indicators used.
· Students will be able to prepare a wet mount slide.
· Students will be able to demonstrate how diffusion and osmosis affects cell functioning and relates to the human body.
· Students will be able to describe permeability of a model membrane for glucose and starch.
