In math, we will work together to discover the circumference of circles. We will start by using our trusty rulers to measure circumference, then we will explore a formula that will make the whole process a lot faster. Be ready for some homework and classwork that you will need to complete. In addition, we will have a quiz on Thursday. HERE is a fun online basketball game that helps you practice finding circumferences of circles.
We will start a new unit of outer-space in science this week. We will start off by talking about famous astronomers in history, telescopes, and constellations. Here is a copy of the powerpoint I will share with you tomorrow:
Astronomy- the study of the universe
Year- the time required for the Earth to orbit once around the sun
Month- a division of the year that is based on the orbit of the moon around the Earth
Day- the time required for the Earth to rotate once on its axis
Telescope- an instrument that collects electromagnetic radiation from the sky and concentrates it for better observation
Constellation- a region of the sky that contains a recognizable star pattern and that is used to describe the location of objects in space.
Zenith- the point in the sky directly above the observer on Earth
Altitude- the angle between an object in the sky and the horizon
Horizon- the line where the sky and the Earth appear to meet
Light-year- the distance that light travels in one year; about 9.46 trillion kilometers
I really enjoyed reading your biome essays! Please see me if you have any questions about the grade you earned.
See you Monday morning,
