Physical Science Experiment 1.1: We took water and added a teaspoon of baking soda and stirred them together. Then we took the ends off of two wires (black: negative blue: positive) that were attached to a 9 volt battery, stuck them into the solution and waited for ten minutes. While we were waiting we observed that bubbles were coming from the two wires. After ten minutes we took the two wires out of the solution and saw that the black (negative) wire had become blue along with the copper. What I learned: I learned that the bubbles were caused by the electricity coming through the wire and broke the water molecules down into hydrogen and oxygen, two types of gasses, which floated to the top of the solution in the form of bubbles.

In the following decay equation 24 11 Na is the......?
Well, isn't that just a happy little decay equation we have here! In the equation 24 11 Na, the number 24 represents the mass number of the nucleus, and the number 11 represents the atomic number. Each element has a unique atomic number, so this equation is showing us the specific identity of the sodium isotope undergoing decay. Just remember, in the world of science, every number and symbol has its own special meaning and purpose.
Two 3 kg physical science textbooks on a book shelf are separated by 0.15 m What is the force of gravitational attraction between the books?
The force of gravitational attraction between the two textbooks is approximately 0.0175 N. This can be calculated using the formula F = (G * m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the textbooks, and r is the separation distance.
What is the difference between a theory and a law in science?
There is much confusion on this issue since the definitions of theory and law in science are quite different than their vernacular usage. A theory in science is a qualitative (meaning with words) description of a series of occurrences than can be shown to exist with a reason or explanation that seems to corroborate the evidence presented. Furthermore, this explanation should be able to predict things that will occur or might have occurred (since we do not have perfect knowledge of past events and are discovering more daily) with relative accuracy. A law in science is a quantitative (meaning with numbers) description of a series of occurrences than can be shown to exist with a mathematical formula that seems to corroborate the evidence presented. Furthermore, this explanation should be able to predict things that will occur or might have occurred (since we do not have perfect knowledge of past events and are discovering more daily) with relative accuracy. The theory is no less important or explicative than the law. It is only the method of explanation that is different. A good example of each can be found with "Gravity". There is a Theory of Gravitation and the Law of Gravity. The Theory of Gravitation suggests that any two pieces of matter will exert an attraction to one-another from the centers of their mass and this pull increases if the objects are more massive or close to one another. The Law of Gravity explains that the amount of attraction that the two pieces of mass exert on one-another is proportional to both masses multiplied by one another and divided by the distance between the centers of their masses squared. In order to get an exact equivalence, this number must be multiplied by 6.674 * 10-11.
