Fun Experiments.... By: Stella


Hello All! This is Stella, writing this blog with pics. Leo will be writing a post about the actual experiment that he tried with the eggs, but here are the pics. of these eggs holding up books! Can you believe it? Filia can't. :P The mother bird is heavy though, so the eggs need to be able to hold up the weight. However, I didn't think that they would hold up this much!

Here is what they are shocked at... :-O

WHOA!!!!!!!!!
The stack is getting higher and higher....

WOW!!! GOLLY!!!

Yeah, seriously.
WHOA!!! One (CRRRRRRRRRRRRRRRUNCH!!!!!!!!!!!)

I guess the eggs died... :)
(By the way, the eggs seen in this photo were de-yolked and whited. In other words, all the insides were dumped in the trash and then we put masking tape on the holes. That's why you don't see a HUGELY juicy mess.) :D
We had a ton of fun doing this experiment! Here is another one....


We took two eggs, one cooked and one raw, not knowing which one was which. We felt them and made a hypothesis. Then we spun them. The raw one was supposed to keep spinning, as the juices inside would keep rushing around, causing the egg to spin...

Mater, holding the two eggs in subject. Any guesses as to which is which!?

Time to spin them!!!
We made another hypothesis w/ the same results as before and then, with our breaths held, shakily cracked the eggs. To our shock, the egg we thought was cooked was really raw!
I learned about this in science, as the boys were learning about eggs. There are certain experimental variables that need to be controlled. But sometimes, the experimental variables can be used to our advantage as we perform experiments such as the previous one listed.
To illustrate my point, I'll use this experiment. One of the experimental variables is: Were we spinning the eggs at the same speed? If you think about it-say you're a 'righty', your left hand won't spin the egg as forcefully as your right hand will. Also, the eggs have to be the same age, as one might be much older than the other.
We might not have cooked the cooked egg completely, and we might have messed up something in the process of shaking them and spinning them, etc.

This shows how much scientists have to do to make sure that their experiments are perfectly designed, without these experimental variables getting in the way.

We had a lot of fun with these experiments and would like to thank Apologia for this post!!!
