Global Science is a difficult subject. I really have to work my best to get things done so I can get credit in this class. But on the other hand I learn.
This year we are going to be working on--introduction to science, geology of California, heat, temperature, and energy, matter, atoms, and The Periodic Table, and the structure of matter.

My first year in global science--
Introduction to Science and Safety--I learned about the safety procedures I need to go through when doing labs and how to measure using SI or the metric system.
The Geology of California--I also learned how earthquakes occur and how to reduce the risk of earthquake damage to a house by using different materials. For example using a certain kind of wood that sways with the movement of the earthquakes will create a house that can withhold damage. I also learned about mudflows, landslides, and creep. Landslide is a sudden collapse of a large mass of hillside and the falling of masses of earth or rock. The Universe-- The Big Bang Theory was really interesting. It's cool to learn that the universe could have been made by a big explosion.
I always thought we lived inside Earth, but when I was learning about planets I found out that we live on the Earth's surface. I also found out that the sun was just a typical star. This subject was fun to learn.
My second year in Global Science--
Matter, Atoms & the Periodic Table--I learned about the Periodic Table. The elements are arranged by the number of protons an atom of that element has in its nucleus. Some elements combine and share or give/take electrons to become complete elements in their energy level. Some elements may give away electrons to become complete while others may take electrons to become complete.
I was never really interested in The Periodic Table and elements in Science before because I did not understand it! Now I have changed my attitude because Steve, my teacher, helped me understand how all this stuff works. Thanks Steve!!!
The REVISED Introduction to Science module--In this module by reading and experimentation, I learned several things that had to do with Science. In my reading and note taking I learned about the characteristics of scientists, the scientific method, and the guidelines that they use in experiments. Steve also had us write down the process of science in a neat and interesting way. This helped me to remember the process of science for the test.
I completed two formal labs--"chicken soup" and "plastic wrap". In the "chicken soup lab" we were testing to see if microorganisms are present in the air. I learned that leaving food products out and uncovered or closed can allow microorganisms that are present in the air to grow and multiply.
In the "plastic wrap lab" we tested 3 brands of plastic wrap (Stretch Tite, Reynolds, and Iris) to see which one would do the best job holding in moisture. We thought "XXXXXX" would work best. We tested our hypothesis three times. At the conclusion of our experiment Reynolds BLUE was proven to hold in moisture best. The companies that make the wrap might be interested in the results of our experiment!
