Part 1: The eclipse observed was a lunar eclipse. The sun is usually not visible during these eclipses. The moon is new during a solar, but full during a lunar. It is red during a lunar eclipse due to a reflection of the Suns light behind earth. It happens more often because Earths shadow is larger than the moons. The umbra is larger as well, so it lasts longer than a solar eclipse.
Part 2: The moon is in the full moon phase. The Earth is in between the Moon and the Sun. The umbra of Earths shadow is cast directly on the moon, casting out the suns light. A tint of the reddish color shines around earth from the Sun making the dark moon appear red. The moons axis is slightly tilted , so the umbra does not hit the moon every month. But when it does? It creates a lunar eclipse.
Interspecific competition
A type of competition in which organisms belong to different species compete with each others for same resources.
Example
Leopard and lion.
intraspecific competition
A type of competition in which organism belong to same species compete with each others for same resources.
Example
birds for breeding or shelter compete with each others
Cell, atom, molecule, electron, proton
1) Mice not radio waved.
2) Radio
3) Strength of mice
4) Maybe inconclusive.
5) Improves strength
Explanation:
- Control Group - Mice not radio waved.
- Independent Variable - radio.
- Dependent Variable - Strength of mice.
- What should Bart's conclusion be? Maybe inconclusive.
- How could Bart's experiment be improved? Improves strength
Experimental setup
setup that is testing a hypothesis using a variable. In most cases only one variable should be tested at a time.
Control Setup
setup that is identical to the experimental setup, only it does not contain a variable.
Independent Variable
The one factor that is change by the person doing the experiment
Dependent Variable
The factor which is measured in the experiment
Constant
all the factor that stay the same in an experiment.
