My experience with Science

Image
As a child, I had always loved science. Throughout school, science was always my one of favorite subjects. Upon entering college, I had to make the hard decision of choosing a concentration for my major. I ended up choosing history but science was always a consideration for me. Looking back, I remember several experiments I enjoyed. In 4th grade, we did the milk and food color experiment. You pour milk into a bowl, add in a few drops of food dye and then add in soap. When adding the soap, it creates the effect of tie-dye. I was  amazed by this and I remember it getting me into the world of science. High school science was perhaps, my favorite years of science. My first three years of high school, I was in honors program. My senior year, I was in a college level course. My freshman year, I was in biology. I remember dissecting a pig in order to learn the body parts and functions. Although it was quite stomach turning, it was interesting to have a hands on experience and see the part

Research Article

The article I chose is the Key to Teaching the Nature of Science by William F. McComas. This article talks about the  Nine core Nature of Science (NOS) Ideas. I have listed them below: Science demands and relies on empirical evidence Science should required data which is reviewed by others. This data should justify all final conclusions. Ideas begin as "exploratory notions"  Can not be dismissed immediately unless there is significant evidence stating otherwise. "The requirement for empirical evidence is accompanied by the caution that not all evidence is gained through experimental means, although that is frequently called the "gold standard" of science".  Science relies on basic observations Scientists use a combination of methods such as: historical observational experimental Science is and must remain an "empirical data-driven pursuit. Knowledge production in science includes many common features and shared habits of mind.

More on Simple Machines!

Simple Machines need some help in order to work! In order to fully understand simple machines, we must be familiar with this vocabulary: Force: the physical interaction between to or more objects! Push and Pull are examples of force pull--> toward the force push--> away from the force Mechanical Advantage: Simple Machines applying force when they are used, making the work easier to do. more simple machines--> higher mechanical advantage  Effort: how much force is applied to the machine Simple machines decrease the amount of effort needed Distance: How much the simple machine moves. Simple machines increase  the amount of distance Friction: the effort used when one object rubs against each other. Three main categories: rough smooth slippery The motion of an object being pulled across that surface is affect by the surface texture.  Compound Machine: made up of two or more simple machines higher mechanical advantage (less effort) One common
