Egg Crush

1 player per team; raw egg

 

Can I crush a raw egg using my bare hands? Middle Scholars discovered the physics of nature is stronger than one might think. When you place the egg in your hand and squeeze, the pressure over the egg is distributed evenly and the egg remains intact. Eggs have what engineers call an ‘arch structure’ at each end. This is an excellent design for supporting weight, which is why it’s the main type of structure used in many bridges. When a bridge with a single arch supports a weight, the force is transferred down each side of the arch into the ground. An egg, with its two arches, transfers any force placed on it through to the entire shell. This makes it very hard to break an egg.

Tangled Umbilical Cord

2 players per team, each with 1m rope with loops tied at both ends that fit loosely around their own wrists

 

The umbilical cord connects a baby in the womb to its mother. The cord runs from an opening in the baby's stomach (the umbilicus) to the placenta in your womb. The average umbilical cord is about 50 cm (20 inches) long. Blood circulates through the cord, carrying oxygen and food to the unborn baby and taking away waste. Inside the cord are one vein and two arteries. The vein carries blood rich in oxygen and nutrients from Mom to baby. The arteries return deoxygenated blood and waste products, such as carbon dioxide, from baby back to the placenta. Antibodies also pass between Mom and baby, to fight against bacteria, viruses and disease.

Rules:

Two intertwined people must separate from one another without (1) cutting the umbilical cord; (2) untying the knots; or (3) slipping the knotted portion over their hands.

Solution:

1. Make a loop in the center of your partner’s umbilical cord.

2. Pass this loop under either of your wrist loops so that the loop portion is closest to your fingers.

3. Pull the loop through with your other hand and open it to a size that will accommodate your hand.

4. Pass the loop over your hand and

5. Pull it down and through the wrist loop.

6. You’re free!  You’re not?  Then let go of the cord and try again.

 

Optional Culminating Activity - Human Body Olympics

Wearing your GUTS shirt is required for participation and it makes for great photo opportunities.

Bottle Burp-Off

2 players per team; baby bottle filled with carbonated beverage

 

What causes burps? Air often makes its way into your mouth, stealing a ride down your esophagus when you swallow. The air is either pushed into your stomach or sits at the bottom of your esophagus giving you that uncomfortable feeling. Middle-school students have mastered the art of forcing the trapped air up the esophagus, and out of the mouth—sometimes on cue. One participant holds the bottle, while the other sits in their lap and drinks. The first one to drink the entire bottle and burp... wins.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cracker Whistle

 1 player/team; zip lock bag with 8 saltine crackers

 

What good is saliva? Saliva keeps the mucus membranes of the mouth moist, making them less subject to cracking and discomfort. This fluid also lubricates food in the mouth, making it easier to chew and swallow. Besides helping with eating and speaking—saliva is a key to whistling. Middle-School students find that out first hand when they eat saltine crackers (which quickly dried up their saliva) and try to produce an audible whistle. Not an easy task. The contestant must eat and swallow all 8 crackers. The first one to whistle, wins.
