IDEAS????
Creating Blood in a Jar
•
•
•
•
Plasma – Caro syrup
Red blood cells – red hots
White blood cells – marshmallows
Platelets – sprinkles
• Do not make this too far in advanced as the dye fades off the candy into the syrup.

Egg Head
Body System: Nervous
Objective: Demonstrate how the CSF
protects the brain during impact

Materials:
1 glass jar with lid
Water
1 egg
Directions:
Fill the jar ¾ full with water
Gently lower egg into the jar
Fill jar to the rim (surface tension should be the only thing
preventing the water from spilling)
• Place lid on the jar (some water may spill)
• Tighten lid and ask for a volunteer to shake the jar
• The egg should not directly hit the sides of the jar enough
to break
• Discuss how CSF protects our brain during impact

What Makes Bones Strong?
Dissolve the calcium carbonate to leave the collagen
MATERIALS:
• Dried, clean chicken bone (a leg or wing bone)
• A glass
• White vinegar
• DIRECTIONS:
• Without breaking the bone, hold the bone and try
to bend it - don't force it to bend; or it will break!
Notice how stiff the bone is.
• Place the chicken bone in the glass and fill it with
vinegar.
• Let the bone soak for 2-3 days, then pour out the
vinegar.
• Add fresh vinegar and let it soak for about 2 more
days.
• After the 4th or 5th day of soaking, take the bone
out and dry it off
Kidney Stones
• MATERIALS:

•
CALCITE STONES, 5 BABY FOOD JARS, COFFEE, TEA, CHOCOLATE ,COLA, WARMING LIGHTS
kidney stone develops from crystals that separate in the urinary tract. Determine if caffeine plays a role in
forming or preventing kidney stones. Using calcite stones to represent kidney stones break several stones to
similar size and place into separate baby food jars. Add a liquid that contains caffeine in different
concentrations such as cola, melted chocolate, tea, coffee to each jar and label the jars. Place a light over each
jar to warm them to the temperature of your body (37 degrees Celsius). Observe for two months. During
this time, add a small amount of hydrochloric acid to each jar to simulate the body's stomach acids. Did the
caffeine solutions cause the calcite stones to shrink or have no effect

Kidney Filtration
• MATERIALS: SAND, WATER, JAR, FOOD COLORING, CHEESE CLOTH
• The kidneys work together as the body's filtration system. An easy science project for any age is to
demonstrate how this works. Mix sand, water, and food coloring in a jar. Half fill another jar with water.
Place cheese cloth over the top and slowly pour the sand mixture over it. The filter will allow the colored
water through, leaving the sand behind. The water inside the jar changes color because of the food coloring.
Dump the water and repeat the experiment adding more water to the sand mixture before pouring on the
cheese cloth. The color of the sand and the filtered water will fade as new water is added. This demonstrates
how the kidneys clean toxins from the blood.

Digestion in a Bag
• Students model both mechanical and chemical
digestion with simple materials.
• MATERIALS: a zip-loc bag, one or two crackers
(saltines work well) and a small amount of clear soda.
• DIRECTIONS:
• The crackers are placed in the bag.
• Students smash the crackers to represent mechanical
digestion
• A small amount of soda is added to the bag.
• After observing for a few moments, students and
squish the contents of the bag. The soda contains
acid, like your stomach does, which helps break down
the food even further. Once the food has been
turned into a slurry, it is ready to be passed on to the
intestines.

Materials: 3 jars, 1 large russet potato, vinegar, knife
Directions:
Cut the potato into three pieces.
Place one third in a chard
Cube one third and place in second jar
Shred the last third and place in third jar.
Pour a small amount of vinegar in each jar
Wait for 20 minutes and then observe results
