kepler's laws

Driving Question: How do systems outside of Earth affect Earth?

Final Answer: they affect the Earth by weather patterns, climate, and location.

3. Why does an object go faster as it gets closer to its star?

kepler's first law- all planet's move in an elliptical orbit

We are learning about kepler’s laws in science.

kepler's 2nd law- a line that connects planet's to the sun that sweeps out equal times and equal areas.

The closer the object gets to the sun the stronger the gravitational pull is going to be on that object.

2. How do stars produce elements?

Supernova- a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.

It produces oxygen and we need oxygen.

Hydrogen-a colorless, odorless, highly flammable gas, the chemical element of atomic number 1. Helium-the chemical element of atomic number 2, an inert gas which is the lightest member of the noble gas series.

During a supernova they explode which causes them to release elements like hydrogen and helium to make other stars.

1. What evidence is there for the Big Bang?

There was static on the radio when we went away from a tower.

Red shift- the displacement of special lines towards long waves

The evidence is cosmic microwave backround.

Radiation cooled the microwaves because the universe expanded, static because there was so much energy released, and leftover radiation from the big bang.
