Meteoroids and the Crater it leaves behind

Thursday, February 4, 2010

We did this experiment to "watch" and learn about the formation of craters. We wanted to see how the size, angle, and speed of a meteorite's impact affects the properties of craters. This is what we found...

First we used white flour and filled up a pan about half way.

2. Next we covered the flour with cocoa.

3. We chose different sizes, shapes, and weights of our "meteoroids."

I let the children speculate on what they thought would happen. Then we experimented :D

Wow!

All of our "craters" were the same shape... round. In fact, all craters that have been seen on the Moon and Earth are pretty much circular. The reason is that an explosion occurs on impact and the forces associated with an explosion are always spherically symmetrical.

I don't know if you've heard of the "Sunday Science" link up, but the next time "Adventures in Mommydom" puts up the post, you NEED to link this up! So many people could learn from this!

The address is:

(Ticia, the blog's author, is morning the loss of a friend right now, so I'm not sure when she will have her link up again. Just keep checking it out!)

Learn for Life!

We are learning for life, not for school!
Education is a progressive discovery of our own ignorance. ~Will Durant
"He is educated who can find out what he does not know." ~George Simmel (1875)
"Let My teaching fall like rain and my words descend like dew like showers on new grass, like abundant rain on tender plants." ~Deut. 32:2
“Listen to Me, you who know righteousness, you people in whose heart is My law: Do not fear the reproach of men, nor be afraid of their insults. For the moth will eat them up like a garment, and the worm will eat them like wool; but My righteousness will be forever, and My salvation from generation to generation.” ~Isa 51:7-8

Simple Faith

The entire Word of YHWH, both “Old” and “Renewed” Covenants, is the instruction of a loving and gracious Father to His children. It is the perfect and unchanging law that gives us liberty (Ps. 119:44-45; James 2:24-26). Nothing will pass from the whole word of YHWH, until everything that will happen, has happened. (Matt 5:17-20). YHWH’s people delight in His instruction (Ps. 1:2). The Torah was not given for salvation. It is the loving instruction of how a redeemed people should live. Yeshua kept His Fathers commandments and lived in His love. We are instructed to walk as He walked (1 Jn. 2:3-6). We are to obey YHWH’s commandments and to hold to the testimony of Yeshua (Rev. 12:17).
