Week 19

 Date Objective/ Procedure Handouts/ Labs Homework
1/14 Cell Processes-1

1. Set up demonstrations to observe osmosis occurring in an egg, carrots, and strawberries

2. Demonstrate how molecules diffuse in and out of a cell through a semi- permeable cell membrane from areas of high concentrations to areas of low concentrations and how water molecules move through osmosis from areas of high to low concentration to achieve equilibrium

 3.  Read Life Science text p. 74- 79 Cell Processes and write definitions for diffusion, osmosis, exocytois, endocytosis, Cell Equilibrium, active transport to understand how materials move into and out of cells to maintain homeostasis 
NJCCCS 5.1  , 5.5, 5.6

Carrot- salt Fresh Water Demo

Strawberries/ Sugar Demo

14. Egg Osmosis

Studyisland Assignment #3 Cells
 

1/15

Cell Processes-2

1.View videos and multimedia to explain diffusion and osmosis in cells while taking notes in Science journal:

A. Diffusion
B. Passive transport &
Active Transport pt. 1, Active Transport pt. 2
C. Endocytosis & Exocytosis
D. Osmosis
E. Cell Equilibrium

2. Observe the Egg Osmosis lab after the water was added to the egg to see which way the water diffused through the semi- permeable membrane
A. Why Can't Humans Drink Seawater?

B. Osmosis Experiment
C. Osmosis Demo
 

NJCCCS 5.1  , 5.5, 5.6

Studyisland Assignment #3 Cells
1/16

Snow Day

 

Studyisland Assignment #3 Cells

1/17

Cell Processes-2

 1.Observe the Diffusion/Osmosis demos days later to see how the salt/ sugar diffused through the membrane in the carrots and strawberries

2.Discuss the roles of carbohydrates, proteins, lipids, nucleic acid. water in cells and work in groups classify compounds as organic or inorganic

3.Complete 30. Cell Processes-1 to review the cell processes

NJCCCS 5.1  & 5.5
