• 3 Different colored Twizzlers
• 1 Sour Punch Straw
• 1 Rubber Band
• 50 toothpicks (attach one skittle to each end)
• 1 Large M&M (peanut or pretzel)
• 1 regular M & M
• Scissors
1. Gather the toothpicks into a bundle and place the rubber
band around the middle to keep them in a bundle.
2.Place a receptor molecule into the cell membrane.
• a. Take one of the twizzlers and place it through the bundle
• b.Bend one end of it into a circular shape. This shape represents how signal molecules bind to
specific molecules. Only a circular-shaped molecule can bind with this receptor.
3.Use the second twizzler as a carbohydrate chain. Place it in the bundle, just as in step 2. Don’t bend
this twizzler.
4.Cut your sour punch straw in half. Place each half into different locations in the bundle. These
represent the protein channels and pumps.
5.Holding the bundle vertically, place the large M&M on top of the bundle. Does it pass between the
toothpicks? Why or why not?
6.Place the large M&M on top of the sour punch straw. Does it pass through the straw? Why or why
not?
7.Still holding the bundle vertically, place the regular M&M on top of the bundle. Does it pass between
the bundle? Why or why not?
8.Place the regular M&M on top of the straw. Does it pass through the straw? Why or why not?
9.Place your mouth on the end of the bundle and blow. Can you feel air on the other side of the bundle?
Why or why not?
10.Explain how the bundle and straws actually represent the components of the a real cell membrane.
11.Roll the bundle between your hands. Do the individual toothpicks move? Without pulling the straw
out can you move it between the toothpicks? How does this represent the fluid mosaic model?
When you are done experimenting, enjoy your candy! ☺

Co2
a compound that reacts with an acid to form a salt
raises the ph. Level
Helps the body by allowing many kinds of molecules
to dissolve in the cells allowing many substances to
be transported
Helps the body by maintaining a constant temperature
Evaporation of water in perspiration cools the body
Water works as a lubricant to protect against damage
Bodies mainly made of, “cradle of life”
O2
a compound capable of neutralizing alkalis lowers
the ph. Balance
Formed by an acid and a base
Organic Molecules
• INRTO - Most living things are organic molecules, meaning that they
contain carbon. Most organic molecules are made of subunits called
monomers which together create a polymer. There are four major
organic molecules. Match their name to their definition below…
Carbohydrates
Lipids
Proteins
Nucleic Acids
Monosaccharide [simple sugar] or
the organic molecules composed of
monosaccharide’s bound together by
chemical bonds.
Substance composed principally of
carbon, oxygen, and hydrogen;
contains a lower ratio of oxygen to
carbon and is less polar than
carbohydrates; generally soluble in
nonpolar solvents
Macromolecule consisting of long
sequences of amino acids linked
together by peptide bonds.
Polymer of nucleotides, consisting of
DNA and RNA; forms a family of
substances that comprise the genetic
material of cells and control protein
synthesis.
