7th Daily Journal
Explain everything you know about NASA and the space program

This Weeks Vocabulary
Electromagnetic spectrum, refracting telescope, reflecting telescope,
observatory, radio telescope

Assignment:	Text Reading 20.1 “Radiation from Space”
The students will be reading through discussing and answering questions about
electromagnetic radiation

7th Homework
Section Assessment 20.1
1.	What is the difference between radio telescopes and optical telescopes?
2.	The frequency of electromagnetic radiation is the number of waves that pass
a point in a specific amount of time.  If red light has a longer wavelength
than blue light, which would have a greater frequency?
3.	It takes light from the closest star to Earth (other than the sun) about
four years to reach us.  If there were intelligent life on a planet circling
that star, how long would it take for us to send them a radio transmission and
for us to receive their reply?

8th Daily Journal
Explain everything you know about physical and chemical changes of matter.

This Weeks Vocabulary
Physical property, chemical property, state of matter, density, chemical property

Assignment:	Textbook Reading 4.1 (Red Textbook) “Physical and Chemical Properties”
The students will be reading through discussing and answering questions about
the properties of matter.

8th Homework
Section Assessment 4.1 
1.	Make a chart and list 10 items in your home.  On the chart include the
following physical properties for each item:  color, state of matter, texture
and hardness.
2.	Design three symbols hat could be put on containers to warn chemists that a
certain chemical could burn easily and be poisonous and corrosive.
3.	Explain why the temperature at which wax melts is a physical property and
not a chemical property.
