The Cart Went BOOM~

Title inspired by that 'incident' that happened today. Don't worry PJ, we know it was Matthew's fault. Haha just kidding...

So, I forgot that I had to scribe yesterday, and I almost forgot about scribing today too! Sorry about that! I'll try to remember everything we did.

Believe it or not, I'm having trouble remembering. OH! Right, we did a lab! 

So the purpose of this lab was to get a better understanding of Newton's Second Law. 

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object depends upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of he object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. 

Now, I'm having trouble explaining the lab. It basically involved a cart, 3 different weights (100g, 50g, and 200g), string, washers, and this timing device (forgot what its called). Put that together and you have our lab! 

After that we had to record our information and create a graph. We had class time today to complete it, but if you didn't finish Ms. Kozoriz said it can be handed in tomorrow.  

I'm sorry this post was late and I apologize that it wasn't in full detail! It's just... hard for me to explain. D:

Hello everybody! It's my turn to scribe so here is what we did today!

In today's class we did a lab called, "Waves on a Snakey." The purpose of this lab was to investigate properties of waves using a snakey (slinky) as a model. After Mrs. Kozoriz explained what we were going to do, she distributed the materials we needed and we broke into groups and got started. The entire class was spent with everyone crouching on the floor and watching in amazement as two people stretched the slinky, and by making quick sideways snaps with our wrist, we created the waves that traveled down, hit the other side, and reflected back. While doing so we had to observe the waves and think about what was happening to the amplitude and the speed of it as it traveled. My group didn't have much trouble, although we debated whether or not the pulse did in fact bounce off each other or pass through. We did ponder on what the meter stick and stop watch was used for, but other than that everything was fine.

Along with this lab we were given a worksheet that should be completed and handed in TOMORROW! And.. I think thats it. I don't know what else to put so I'll end it here.

The next scribe was picked by random so congratulations 'kaleiscool'! You're next! Have fun!
