week if january11th

Monday:

- On Monday we talked about what a neap tide was and what a spring tide was.

Neap tide- When the moon and the earth are at a right angle to each other. When there is a neap tide there are moderate high tides and moderate low tides.

Spring tide- When the sun, moon, and earth are in line, it is called a spring tide. When there is a spring tide there are higher "high tides" and lower "low tides"

On Tuesday:

We went on Mr.Finley's website and looked at the simulation. We talked about that and answered questions.

On Wednesday and Thursday:

We took the honors bio test that I think I failed!!:)

On Friday:

- We talked about why we have seasons.
- We have seasons due to the earth's tilt.
- The earth is tilted at the same degree forever.
- Another reason why we have seasons is because we revolve.

I'm not sure if we are supposed to blog about today but I will anyway.

Today(Tuesday):

We watched part of a movie. We were also supposed to find out what a solstice and an equinox is.

Solstice: an event that happens twice a year, when the tilt of the Earth's axis is most inclined toward or away from the sun.

Equinox: occurs twice a year, when the tilt of the Earth's axis is inclined neither away from nor towards the sun.

Why is it so important to learn this stuff?

this tells us why there are seasons and why they change.
