ASSIGNMENTS: Observation Assignment due today. I will also accept late ones today
Observation Assignment – Due on Wed Aug. 31st.Between now and Wednesday, I need you to go outside between 6:00AM and 6:15 AM (yes, in the morning) and look to the east (the direction the sun rises). It should still be dark and you should still be able to make out a few stars (10 -15) and maybe a planet or two.1)Create a drawing of what you see. (Remember this is NOT an art class – do your best but creativity will be rewarded.) Your drawing should be no bigger than a sheet in a composition notebook (5.5 x 8.5 inches with the long side being the horizon)2)Roughly indicate the horizon (bottom of the sheet) and with the top side of the sheet being about two handspans (About 40 degrees of sky). Draw in dots to indicate the planets and stars. Make sure your marks indicate the color and how bright the objects are (bigger dots for brighter objects) 3)If you think you think you can identify an object then do so on your sheet.4)Try to be as close to scale as you can.

Solar System Scale ActivityMaterials:* A long thin strip of paper at least 30 cm long (a sentence strip works well)* PencilDirections1) Place the piece of paper on your desk in front of you vertically (so that it is tall instead of fat). In very small letters, write “Sun” on the very top edge of the strip and “Pluto” on the very bottom edge.2) Fold the strip in half (top to bottom) and open it up again, showing the crease.
Solar System Scale Activity3) What planet do you think might belong on the crease (halfway from the Sun to Pluto)? Write your guess on the crease.4) Write in the rest of the planets on the strip of paper, making sure you put them in order and keep their relative locations where you think they should be.5) When your teacher provides the “answer key”, write down the answers on the other side of the paper. Compare the correct answers to your own.
How did you do?
To Make the Answer Key:1) Turn strip over and refold halfway between Sun and Pluto. On the crease, write Uranus.2) Fold Pluto to Uranus. Write Neptune.3) Fold Sun to Uranus. Write Saturn.4) Fold Sun to Saturn. Write Jupiter.5) Fold Sun to Jupiter. Write Asteroid Belt.6) Fold Sun to Asteroid Belt. Write Mars.7) Fold Sun to Mars. Write Venus.8) Write Mercury in between Sun and Venus.9) Which planet is missing?
Write in Earth in between Venus and Mars.
Scientific Models—A SurveyQuestion 1: How would you describe what a model (in science) is to someone who didn’t know this term? Give two examples of models.Question 2: What are models in science used for?Question 3: How close does a model have to be to the real thing?Question 4: What is important to include in a scientific model?Question 5: Can scientists have more than one model for the same thing? Explain your answer.Question 6: Are there circumstances that would require a model to be changed? If yes, what are they? If no, why not?
