Osmosis and Diffusion Lab
Osmosis and Diffusion lab includes hands-on inquiry based activities. The
module is divided into three parts: a. teacher demonstration of osmosis
and diffusion using Gummy Bears, salt, celery, food coloring, and hot and
cold water; b. hands-on student labs to demonstrate diffusion using various
concentrations of corn starch and Lugol’s solution; c. hands-on student lab
to demonstrate osmosis using dialysis tubing, sucrose solution, corn starch,
phenolphthalein, ammonia, vinegar, and universal indicator solution.

1. Describe characteristics common to living things,
including growth and development, reproduction,
cellular organization, use of energy, exchange of gases,
and response to the environment.
2. Identify functions of organelles found in eukaryotic
cells, including the nucleus, cell membrane, cell wall,
mitochondria, chloroplasts, and vacuoles.
3. Relate major tissues and organs of the skeletal,
circulatory, reproductive, muscular, respiratory,
nervous, and digestive systems to their functions.
5. Identify major differences between plants and
animals, including internal structures, external
structures, methods of locomotion, methods of
reproduction, and stages of development.

Primary Learning
Objective(s):
. The student will understand the processes and the effects of life activities
in plants and animals through osmosis and diffusion.
2. The student will understand how a solute size and concentration
gradient affects diffusion across semi-permeable membranes.

3. The student will understand the process of diffusion and its importance
to cell function.
4. The student will understand that osmosis is a specialized form of
diffusion.
5. The student will view a Power Point Presentation and participate in an
interactive class discussion to learn basic facts about osmosis and diffusion.
6. The students will perform experiments involving osmosis and diffusion
and record data from these experiments using data tables and data
analysis.

Remediation:
Each area below is a direct link to general teaching strategies/classroom accommodations for students
with identified learning and/or behavior problems such as: reading or math performance below grade
level; test or classroom assignments/quizzes at a failing level; failure to complete assignments
independently; difficulty with short-term memory, abstract concepts, staying on task, or following
directions; poor peer interaction or temper tantrums, and other learning or behavior problems.
