I am working as a scientist.
Today I worked on a science experiment all day (Just like the class did with our matter experiment on melting ice vs. ice with salt.) Steve is one of the leaders of my climate change research.
He is working on an experiment that is trying to predict if the treeline will be affected by climate changes. First you need to know what a tree is? Please find the definition of a tree. Then we can compare your definition to Steve's definition.
Last week another group of Earthwatch members took samples from trees. They cut the end of the tree which is called the branchlet. We had to take these 560 branchlets and follow a specific procedure in order to collect all the data.
1. Label the data trays (or egg cartons) that held the branchlets.
2. Prune the branchlet so it contains only the growth from 2008.
3. Measure and record the length of the branchlet.
4. Dip the end of the branchlet in hot wax to prevent moisture loss at the end.
5. Weigh the branchlets and record.
6. We will be repeating the weighing process 5 more times in order to measure the moisture loss in the branchlets.
These branchlets are from spruce trees so it smelled like winter and Christmas all day.
