Science+3

Welcome to your class wiki! In this space, it is my hope that we will be able to creatively share with others what we are learning in class. This space is yours to collectively and collaboratively communicate your knowledge and understanding of scientific concepts.

2-19-08 During the month of February we have been studying mixtures. Mixtures are made up of 2 or more elements phisihcally combined. Solute are less seen in a mixture and are the ones that disolve and solvents there are more of and does not disolve. water is known as the universal solvent beacuse it is known that many things dissolve in water, but some resist water and must be shaken stired or heated to combine. Also that heterolegenius has all the same mixtures in it.

2-20-08 Today we went over solubility and concentration.We also went over our homework on concentration by mass ans by volume.

3-10-08 Today we are going over speed and velocity. We got done with a worksheet determining speed.

3-10-08 Today, we are learning how to convert minutes into seconds and hours. We also learned the formulas for velocity and speed. this is most of the stuff we have been learning for motion and we will learn even more.

3-19-08 Today we were discussing the difference between velocity and momentum.The product of mass and velocity is the amount of momentum. The equation for momentum is written p(momentum)= M(mass)xV( velocity).

A man named Newton made up three laws that tell us moving objects. He said that all things have inertia. This means that objects that are not moving will stay not moving and objects that are moving want to stay moving. He also said that things with more mass will need more force to make them change the way the are moving. Finally he said that every action there is a reaction.
