The Sun and Stars

Below are videos that will help you understand the sun and stars.
After each topic are questions for you to answer in your science journal. For homework, take notes while you watch and answers the questions in your science journal.  Write the date & topic as your header. Type & paste or write the answers in complete sentences with neat handwriting in your science journal.

The Sun and Other Stars

1. Sirius, the brightest star in the sky, is 8.8 light years from Earth.  If light travels at 299,792km/sec (300,000km/sec). How far away is Sirius in km? WHich year did Sirius give off the light you see when looking at the star today

                1light year(ly)= speed of light x time

                300,000km/sec x 1year x 365days x 24 hrs x 3600sec

               =9,460,000,000,000km or 9.46 x 10 to the 12th power km is the distance light travels in a yr.

Planet Project

Planet Project

  You and your partner will be creating a scale model of your planet to be put on display.
Research your planets, including their diameter, radius, period of rotation, average distance from the sun, period of revolution, and number of moons, composition, atmosphere,  and any additional information, and prepare to present what you've learned during the final building of the model. Each student will be creating a planet flipbook that will include information from your presentation about your planet.

• Project DUE: Tuesday, APRIL 16th 
• TEST on planets and solar system: Thursday, APRIL 18th

Procedure
a. Fold the book as instructed in class.
b. Cut and glue the rubric to the back of your flipbook.
c. The top page should include a cover page (title, picture and name)

After taking notes on presentations...
d. Each subsequent page needs to include a colored, accurate illustration of the planet
e. Include information on each planet about the: diameter, radius, period of rotation, average distance from the sun, period of revolution, and number of moons, composition atmosphere, and any additional information.
f. In addition to the basic information listed above, you will need to include three other facts from the book or the video.

4	·      Illustrations are neat, colored and realistic. ·      Book has all of the required information and is accurate. ·      More than three facts listed which are well-written and interesting. ·      Writing is legible.
3	·      Illustrations are colored. ·      Book has most of the required information. ·      Three facts are listed about each planet.
2	·      Illustrations are incomplete. ·      Book does not have all the required information. ·      Some facts are listed. ·      Writing is sloppy.
1	·      We had to do drawings?? ·      What was required? ·      No facts listed. ·      There appears to be carbon markings on the paper.

Planets Science Journal

Answer the question below after watching the videos in your science journal.

• DUE: APRIL 11th

1. Write down at least 3 facts or descriptions about each planet and the sun.  Draw a picture of the planet next to the description or facts.

Comparing our Planets

Comparing Size and Distance in the Solar System by Bill Nye
Go to OMG science link and play around to get more information about each planet.

Science Activity

Pick a partner(s) and get your assigned planet. Use the information below, plus the diameter of the model Sun chosen by the class, to determine the size of their planet and orbit radius for the model.

Below is an example calculation to determine the size of the model Earth, when using a 12-inch diameter Sun:

(Earth’s diameter / Sun’s diameter) * x inch model Sun diameter =
(12,742 km / 1,391,900 km) * 12-inches =
Answer: The diameter of the model Earth will be 0.1099 inches.

After finding your calculations for your model, fill in the chart on the Science board.
Challenge: As a class determine the distance between each planet in your models.



Research your planets, including their composition, atmosphere, orbit length, presence (or absence) of moons and any additional information, and prepare to present what you've learned during the final building of the model.


Solar System Model

Welcome to Solar Systems

Below are videos that will help you understand our solar system and how it stays together.
After each topic are questions for you to answer in your science journal. For homework, take notes while you watch and do a rough draft of your answers to be prepared for the next class.  
During the next class time, you will have time to revise and edit your answers. Write the date & topic as your header. Type & paste or rewrite the answers in complete sentences with neat handwriting in your science journal.
