Summary:
Radioactive dating is important when you want date rock or fossils. First, you find a type of material within the object. For dead things, you measure carbon, and for non-living things you measure Uranium. Next, you find out how out how many of that material is within the item. For example, the half-life of carbon-14 is 5,730 years. So say that item has 50% carbon-14 within it. This means that the item is 5,730 years old since 5,730 means that there is 50% carbon-14 remaining. So that object has been around for 5,730 years.

S&EP:
SP2: Developing and using models
This week I performed SP2: Developing and using models because I used a model to find the age of an object such as a bone. A picture of this is included above. I used a model to find the age of objects through the knowledge of the material and its half-life to determine the age of an object.
