Earth's Layers:
The earth has four layers. The crust, mantle, outer core, and inner core. The crust is 25 miles thick. The mantle is 1700 miles thick. The outer core is liquid and the inner core is a solid.
An earthquake is measured with a seismograph. There are P-waves which are the primary waves. They are faster and they can travel through liquids. The secondary waves are called S-waves and they cannot travel through liquids. Earthquakes are measured using the Richter scale which gets exponentially larger as the earthquakes increase. |
Model of Orbits:
Our model showed orbital velocity. We had to find the orbital velocity for planet X with only two variables. We were give the orbital period of planet X and the distance it travels in one orbit (the circumference of the orbit). We used the equation of V=D/T to find the orbital velocity of planet X to be 0.00318 m/s compared to the earth's orbital velocity of 29.8 m/s.

Solar Angles:
At San Marin the sun is in the south throughout the day because we are in the southern hemisphere. The sun rises in the east and it sets in the west. At noon the sun is at 30 degrees in the winter and 70 degrees in the summer. This is because the earth is tilted on an axis so as it spins different parts of the earth are facing towards the sun.
Atomic Structure:
A molecule is made out of two or more atoms bonded together. Some examples are H2O, H2, and O2. The gold foil experiment was conducted by Ernest Rutherford, Hans Geiger, and Ernest Marsden. It proved that the atom has a very small dense center called the nucleus. The protons and neutrons are in the nucleus while the electrons are on the outside.
Heat is a form of energy. It is due to the vibration of molecules. Radiation is heat transferred through space as a wave. Conduction is heat transfer through a solid and convection is heat circulation within a fluid. |
Day lighting Design Model:
We tested day lighting techniques by designing a cardboard house. Our house had six rooms including a living room, a garage/kitchen, a hallway, a bathroom, and two bedrooms. We tested windows, clerestory windows, solar tubes, skylights, and light shelves. We found clerestory windows and sky lights to be the most effective with 50% and 40% brightness in the evening and at night. We tested each room at noon, in the evening, and at night.

Justification Document:
Science Building Project:
Our building will have 10 class rooms, 2 bathrooms, and one teacher prep room with storage space. Each classroom will be 38ft*28ft. Each classroom has at two doors. Some key features in our building are the study spaces. We have a hallway with vending machines and a outdoor quad area. The roof has usable space that you can use for demos or studying.

Our building will have 4 Skylights that are 20x40', 2 skylights 6x38', 12 clear story windows 3x3' on both sides, 6 clear story windows that are 6x20', and 6 windows in each room. We found skylight and clear story windows to be the most effective. The windows are on the south side so we can maximize the amount of light. We will use a white or milk color for the walls to make the room bright. Our walls are 1’ thick so they will retain the heat and maximize our classroom space.

Building Materials:
Sheetrock: Sheetrock will be used on our walls to be easily painted
Aluminum doors: Used because they are like the doors on campus
Concrete foundation: Used to support the entire building
Outside Vinyl: Used to seal the outside from weather and noise
Soundproof ceiling panels: Allow direct sunlight without the distractions of outside noise
Linoleum floor tiles: Laid down for the surface on the floor

Reflection:
During this project I learned a lot about how I work in a group. I did a good job at delegating tasks and including everyone. Our group did a good job at work effectively and all working to complete the model. We also did a good job on staying under the two minute limit and practicing so we wouldn't go over. Some parts of our presentation went poorly. We did not have the model within our presentation so we could not share it when presenting. I could have improved on communicating with my group and preparing to present. We were not fully prepared to present and we could have improved on this.
I learned that it is not good to rely on technology. We should have pictures or other things that can easily be showed. I also learned that dividing up the work load works best. Instead of all of us working on one thing we divided the project into different sections. Some of us worked on the model and the others worked on the presentation.
