Picture
As we begin to look at the Moon, Earth's largest satellite, stayed tuned to this blog post for all of our class activities, websites to learn more, videos, and to submit any questions.  All question for either Mr. Reese or your classmates (on this topic) should be submitted in the comment section of this post.  --Mr. Reese

Assignment - T0 be completed over the next month

Charting the Moon...Direction are bellow
  1. Each night observe the night sky and look for the moon.
  2. Click on Charting the Moon (this).  
  3. Record you observation in the document provide on the above Link

Earth and Space Science (Grade 7 Next Gen Standard)
  1. The relative patterns of motion and positions of the Earth, moon and sun causes solar and lunar eclipses, tides and phases of the moon

  • The moon’s orbit and its change of position relative to the Earth and sun result in different parts of the moon being visible from Earth.
 
 
Find a video using the below links or google search.  Look for a video focusing on science (nature, animal behavior, physical, weather, ect...).  Write a five sentence blog summarizing the video.

Waves

22 Comments

 
A wave is a moving disturbance that transfers energy through matter or space.
Investigate the wave simulator below....

....answer the following questions in the blog section...
  1. Set the wave simulator to "oscillate" and "no end"
  2. What happens to the waves when you increase amplitude?
  3. What happens to the waves when you decrease amplitude?
  4. What happens to the waves when you increase frequency?
  5. What happens to the waves when you decrease frequency?
  6. Notice that the dots on the wave go up and down while staying somewhat in place...explain why this happens...make sure you use what you know about energy waves to answer.
 
 
Energy can be transformed, or changed, from one form to another.

Assignment...Post in the comment section
1.  Provide an example of chemical energy transforming.
2.  Provide an example of the Sun's nuclear  energy transforming.
3.  Provide an example of thermal or heat energy transforming.
4.  Provide an example of potential energy transforming to kinetic energy
 
 
Energy comes in many different forms....

Assignment...
  1. List the 7 types of energy listed on page 1 in study island.
  2. Complete the simulation below...as you change the variables for the skater what happens to the amount of energy used? 
  3. Explain what the Law of Conservation of Energy is.
 
 
Humans depend on energy for many activities every day. There are many different ways of obtaining, transforming, and distributing this energy, each of which has different environmental consequences.

Assignment...answer the following in the comment section...
  1. Select an energy source (renewable or nonrenewable) and make a case or argue why it is the best source of energy for people to use.  Include at least five facts about the energy source (for example, location, how abundant it is, is it renewable/nonrenewable, cost, and so on...). 
  2. Include at least one professional source other than study island with your answer....no Wikipedia this time, fine a credible website dedicated to your energy source....copy and paste the web address in your post.
 
 
In Class assignment for this week...no post.
 
 
Today you are to investigate one current news event.  For this you can either read an article from an online newspaper (links are below) or watch a video from a network news station.

Steps to complete your assignment:
  1. Find an article
  2. Read or watch the story
  3. Summarize the story in 5-7 sentences
  4. Write a 2 sentence response to your summary.  Include your reaction to reading the article. (this should be what you think...opinion!)
  5. Post your article on the comment section of this blog post and include the link to your article or video.
Newspaper links:

Matter can undergo physical and chemical changes. When a physical change occurs, a substance changes without altering its composition. When a chemical change occurs, a substance has chemically reacted to form one or more different substances.

Assignment....
  1. Complete the Changes Online LAB  (click on lab to use the link then click on run module)
  2. Post in the comment section 3 examples of Physical Changes AND 3 examples of Chemical Changes
  3. Explain the Law of Conservation of Matter (can be found on page 2 of study island lesson)
 
 
Matter on Earth is generally found in one of three different states: solid, liquid, or gas. Another common state of matter that is much more rare on earth is plasma. The state of matter that a substance has depends on the arrangement of the particles, the attractions between particles, and the amount of energy the particles possess.
Assignment...Only 1 question this week, be complete and detailed.

1.  Using water as an example, in one paragraph describe and list the three phases of matter that water exhibits, how it changes from one phase to the other and whether or not the mass of the matter changes as it goes from phase to phase.
