RESOURCES:
-
A computer with Internet access, the necessary plug-ins installed for the
interactive
activities,
and a printer will be needed.
-
You will need the items to complete the discovery tasks and labs. (See
the materials list for each lab activity.)
-
Have pencil, paper, and science notebooks ready at all times.
 DISCOVERY
TASKS:
Cells are the basic building blocks for biotic substances. Cells
contain small structures called organelles
allowing them to get and use energy,
grow and develop, eliminate waste, respond to changes, and reproduce.
All living cells whether animal, plant, fungi, protist, or bacteria, must
be able to perform these life processes. Therefore, similarities
and differences exist in the composition of these cells.
 ACTIVITY
#1: CRISS-CROSS PUZZLE
Grab your pencil, paper, and science notebook
and also visit these sites to continue learning more about organelles and
cells. As you explore
collect more data in your science notebook to assist you in creating
a challenging puzzle.
-
BrainPop
- Be certain to check out the Cell Movie, Activity Page, Tune in
with Cassie & Rita, and Experiment with Bob the Ex-labrat.
-
Life Science
Connection - Explore the plant and animal cells, but don't miss the
bacteria, protist, and fungi safaris.
-
EXTRA CREDIT: In your science notebook
make a drawing of the gumbolimbo tree that resembles the photograph
after you successfully complete the expedition
(self-test).
-
Animal
Cell - Be certain to click on the plants and animal cell link
for tons of great information.
-
Animal and Plant Cells
- Here you'll have an opportunity to manipulate a virtual microscope.
-
Cells Alive - Select Plant Cell
in the menu to start and don't stop until you've toured the plant, animal,
and bacterium cell.
PUZZLE: Using your science notes and the Internet data in teams of
two, create your CRISS-CROSS
PUZZLE . GOOD LUCK!
-
Incorporate 20-25 terms and/or facts.
-
Print 3 copies.
-
Submit one blank puzzle and one completed copy as the answer key.
-
Exchange the third copy with another 2-member team. Try your hand
at their puzzle and submit it when completed.
 ACTIVITY
#2: CELL MODELS
Cells are microscopic and most can only be seen through the use of
a microscope. Now that you're familiar with many of a cell's organelles,
you are about to take a tour of a virtual
cell.
-
In your science notebook, entitled Virtual Cell, write five discoveries
you made about cells on your journey.
-
Your turn to make a 3-D
model of a plant cell. Be creative, bring other organelle materials.
(Don't forget teacher authorization.)
-
Now you have the opportunity to create a cell model to wear! (See
teacher for Cell T-shirt Project instruction sheet.)
-
In your science notebook, entitled Diagram
of a Typical Plant Cell, record your answers #1-15.
-
EXTRA CREDIT: Visit the Java
Based Tutorial at this site, then in your science notebook number #1-11,
identify
each organelle, and finally match it to its special fact. (Oops,
no #8!)
SPECIAL FACTS: *contains m-DNA and ribosomes
*interior membranes are surrounded by atoms
*not a membrane bound organelle *major component
is most abundant organic compound *filled with
cell sap
*semi-fluid substance *semi-permeable membrane
*no additional info given *contains nuclear pores
*coin-like stacks of thylakoid membranes
ACTIVITY
#3: MITOSIS - ONION ROOT TIP PROJECT
As most cells grow and develop they eventually reach a point
of reproducing. Using a division
process called mitosis, cells go through five
different stages. Explore these five phases when you click here
for the Cell
Cycle and Mitosis Tutorial.
-
Obtain a copy of the Onion Root Tip activity sheet from your
teacher.
-
As you explore the tutorial, compare and combine information with your
science notes.
-
To begin the Onion
Root Tip Project click on the phase image and place it under
the phase title where you believe it belongs.
-
Submit your activity sheet with a
graph illustrating your results concerning the time spent on different
phases of the cell cycle.
ENRICHMENT
ACTIVITIES:
-
CELL THEORY RAP - If memorizing is tough to do, try a RAP; its up
to you! Here's a sample so you can start, just add on to show
your smarts. *** Listen close to the story I tell: it's
the rapping story of a living cell. It's a happy tune that's
sort of cheery, about a real tough topic called cell theory.
*** Around the cell, you'll find a "skin." This
cellular membrane holds the whole cell in. But its job isn't
simple, there's no doubt, it lets some things in
and some things out. ***
-
ALIEN CELL GAME
- Destroy alien cells that have invaded your body before they undergo mitosis.
Use the arrow keys to move
your microscopic ship. Read the instructions for the game for
helpful hints.
