Algebra 1, High School Biology Recommended: The CLEP covers two years worth of material. Those wishing to take the CLEP will have to do significant additional study. This curriculum includes topics such as matter, atomic theory, the periodic table of the elements, bonding, chemical equations, chemical bonding, stoichiometry, gas laws, acids, bases, and salts, reaction rates, thermonuclear and nuclear chemistry, and equilibrium. Students learn through texts, videos, online tutorials, as well as through hands-on and virtual laboratory experiments. A midterm and final exam will be given. All the pdfs not listed with a separate source are from this GVL course, though they may have gotten them from a different source themselves.

Topics Isotopes; Atomic Mass; Description Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.
It is science, though many times confused as being the same thing. I’ll prove my point. You know that I could never have been inside of your mysterious building out there, and I imagine you can be sure no one has told me its secrets. Yet I’ll bet that I can describe fairly accurately what is in there—not from seeing the machinery, but from knowing what must be done to oil in order to get the products you need. You want to hear? Your crude oil runs into a tank of some kind, and you pipe it from there to a retort , some big vessel that you can seal airtight.
Once it is closed, you light a fire under the thing and try to get all the oil to an even temperature. A gas rises from the oil and you take it off through a pipe and run it through a condenser , probably more pipe with water running over it. Only my family have seen, no others—I’ll swear to that! I told you that we have been doing this stuff for years in my country. I’m not out to steal your secrets.
In fact, they are pretty small potatoes where I come from, where every farmer has a still for cooking up his own mash and saving on taxes.
Although more expensive than radiometric dating, AMS dating has higher precision and needs small sample sizes. Aside from archaeology and geology, AMS dating is also used in other fields like biomedical research and ocean sciences research. There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry AMS.

For each pair of students, you will need: Context This is the first in a three-lesson series about isotopes, radioactive decay, and the nucleus. The second lesson, Radioactive Decay: An Analogy to Carbon Dating , is based on gathering evidence in the present and extrapolating it to the past. This lesson helps students build their understanding of the properties of matter, specifically it will help them understand that average atomic mass is not a simple average, but is weighted according to percent abundance.
Before working on this lesson, students should be familiar with the periodic table and should have had some basic instruction in the following concepts: Students should be able to describe an atom and its basic structure. This lesson helps students understand the important notion that neutrons in the nucleus add to an atom’s mass. Prerequisite understanding for this lesson can be found at the level, particularly the idea that “atoms of any element are alike but different from atoms of other elements.
Electrically neutral particles neutrons in the nucleus add to its mass but do not affect the number of electrons and so have almost no effect on the atom’s links to other atoms its chemical behavior.

Atomism The idea that matter is made up of discrete units is a very old idea, appearing in many ancient cultures such as Greece and India. The word “atom” was coined by the ancient Greek philosophers Leucippus and his pupil Democritus. As a result, their views on what atoms look like and how they behave were incorrect.

Here is an outrageous thought: All the matter around you is made of atoms, and all atoms are made of only three types of subatomic particle, protons, electrons, and neutrons. Furthermore, all protons are exactly the same, all neutrons are exactly the same, and all electrons are exactly the same. Protons and neutrons have almost exactly the same mass. Electrons have a unit negative charge. Protons each have a positive charge.
These charges are genuine electrical charges. Neutrons do not have any charge. Even more outrageous is the shape of the atoms with the three subatomic particles.
Purpose To develop the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students will use a simple graph to extrapolate data to its starting point. Context This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay. The first lesson, Isotopes of Pennies , deals with isotopes and atomic mass.
The role-playing game Traveller popularized the use of tech levels in The tabletop boardgame Civilization popularized the use of tech trees in And pretty much every 4x game uses tech trees, with the items accessed by investing in tech research.
There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn’t know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10, years old. Radiometric methods measure the time elapsed since the particular radiometric clock was reset.
Radiocarbon dating, which is probably best known in the general public, works only on things that were once alive and are now dead. It measures the time elapsed since death, but is limited in scale to no more than about 50, years ago. Generally applied to igneous rocks those of volcanic origin , they measure the time since the molten rock solidified.
If that happens to be longer than 10, years, then the idea of a young-Earth is called into question. If that happens to be billions of years, then the young-Earth is in big trouble.

By Kataxe Beta decay either increases or decreases the atomic number of the nucleus by one. You may need your parents help with this. For safety reasons, the landing field might only share its location with the emergency spacecraft services and maybe limited refueling. As a test, Von Weizsacker suggested looking for excess 40Ar in older K-bearing rocks.
An observer viewing the atoms from a view that does not include the continuous spectrum in the background, instead sees a series of emission lines from the photons emitted by the atoms.

Atomism The idea that matter is made up of discrete units is a very old idea, appearing in many ancient cultures such as Greece and India. The word “atom” Greek: In the early s, John Dalton used the concept of atoms to explain why elements always react in ratios of small whole numbers the law of multiple proportions. For instance, there are two types of tin oxide: This means that g of tin will combine either with

At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4. In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way. At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column.
Although there were attempts to make relative age estimates, no direct dating method was available until the twentieth century. However, before this time some very popular indirect methods were available.
