Dec. 11, 2009: Create a graph of the 4 substances that had heat transfered to them by Radiation from the heat lamp. In Photos and Docs there is a word tutorial that will help you create a graph using Excel software. It's 4 pages long and in color (if you wish to have it in color) print it out to have a coy for future reference. Dec. 9, 2009: Next Quiz is scheduled for next Tuesday 12/15/09. Topics covered-temp and pressure at different altitudes. Heat transfer:Conduction, Convection and Radiation. Check out Quia Link. Dec. 9, 2009: Reminder_Global warming articles are due next Wed. 12/16/09. All 3 articles should be read and referenced (meaning- you need to document your source. Especially if you get it off the internet. Site the URL or web site where you got the information) and you need to highlight key, important points of each article, so that you can tells us about them. Cap and trade is one way to try and cut back on the amount of CO2 greenhouse gas. Find out what Cap & Trade means-pro and cons etc. visit the link below. You can copy and paste this web site to your address bar or go to my links and click on it. http://www.ecomii.com/ecopedia/cap-and-trade What's your opinion of CAP and Trade??? Is this a solution or will it lead to other problems?? Dec. 7, 2009: Answer the 5 questions regarding CONVECTION. The questions are on a worksheet under Photos and Docs. Titled:"Convection Questions". Print out this worksheet if you can; then, answer the 5 questions. The answers will be related to the experiment we did in class with the water and red die. Problem Solving: Also, if you didn't finish the question about the sub stuck at the bottom of the ocean; finish answering that too. You have to find a way to get the sub to the surface without power. The sub can only move horizontally-back or forward. You need to find "something" at the bottom of the ocean that will lift the sub to the surface via convection. Several weeks out: Between now and the next couple of weeks find at least 3 articles about "Global Warming"; from newspapers, magazines and research on the internet. You might want to start with The Climate Conference in Copenhagen Dec. 6-18, 2009. Then find articles that tell you what Global Warming is and what our (the US's) position is on it, what the rest of the world says about it etc. Key terms: COP 15, Kyoto Protocol, UNFCCC, IPCC - (what do these terms/acronyms mean) DUE Dec. 16, 2009. Nov. 30, 2009: Answer the following question: How does altitude effect the boiling point of water and the cooking time of food? Here's the rule to use to help you understand and answer the question. In order for water to boil it must overcome the pressure or weight exherted by the air. (14.7 lbs/sq. in at sea level) So, if you believe that water comes to a boil sooner at higher elevations, then the temperature will be lower than 212 F/or 100 C and the cooking time will be longer because the temperature is lower. If you believe the water takes longer to boil at higher elevations than the opposite is true of the length of time it takes food to cook. Think about the weight of air at different elevations and how you might overcome lifting weight. Hint: The heavier the weight the harder it is to lift or overcome the weight - the light the easier. So, now think what happens to the weight of air as you go up? Does it increase-get heavier or decrease-get lighter. Look at your Pressure Graph. So, to answer the question you need to say whether water comes to a boil sooner or later at higher elevations and then what this means to the length of time your food needs to cook. (will it take longer to cook or less time to cook and why?) Try this-with your parents: Boil water with and without the cover on the pan. Which comes to a boil (time each) sooner-covered or uncovered? Why? Nov. 21-23 weekend: Visit the weather Quia link (under links) for games and activities to assist with your preparation for Tuesdays 11/24 quiz on clouds and layers of the atmosphere. Nov. 18, 2009: Label the layers of the atmosphere (Thermosphere has 2 layers inside it) and answer the 8 questions on the back. Nov. 17, 2009: The Atlantis Space Shuttle will dock with the ISS tomorrow Wed. 11/18/09. You can try to catch it as it flies overhead. The following link provides a schedule of when to look for it. Click your country, state and town- (Worcester) to get the appropriate flyby schedule. http://spaceflight1.nasa.gov/realdata/sightings/ go to my link: ISS siting Schedule. Nov. 13, 2009. Friday the 13th. Over the weekend get the worksheet signed by a parent confirming approval for and assistance with the experiment: "Making a Cloud in a Bottle". You can print out the questions and the instructional steps under Photos and Doc of my web site. Titled: Making a Cloud in a Bottle. There are questions you need to answer. This will be due Tuesday Nov. 16th. Nov. 12, 2009 Track Hurricane IDA's path. Go to weatherforyou.com and scroll down the left hand side margin until you come to hurricanes; click on it and see where this huuricane has been and the different descriptions of hurricane categories. Just click the cursor over each category to read information about that category. (wind speed,storm surge levels etc.) Answer the following questions: 1. Where is IDA today 2. What category storm is it? 3. What is its wind speed? 4. Predict if IDA will come close to New England, when , and how much rain will it bring if it does hit. NOTE: Based on the current weather data you may not be able to get the information you're looking for at this web site,.... so listen to the weather report tonight and get as much information as you can from the weather report. Also check out NOAA's web site to see if there's any information there about IDA. Get what you can by listening to the weather report. Nov. 10, 2009: Study for Weather Tools Quiz on Thursday. Your Weather Tools/Instruments worksheet is your study guide: but there's a big focus on how the barometer and Hygrometer work. Nov. 6, 2009: Answer the 3 questions on your "Under Pressure" worksheet. Answers are due in class Tuesday Nov. 10, 2009. Write your answers on a separate piece of paper, if you need to; (computer) typed would even be better. NOV. 4, 2009: Using your barometers record the high or low pressure and the kind of weather you observe. Nov. 2, 2009: Making a home made aneroid barometer or a mercury type barometer. Both are examples of the 2 types of baromters that measure air pressure. In class on Monday I will hand out a worksheet that explains how to make a home made aneroid barometer. You will need several materials. The container is the most important item. Since you will not be bringing this barometer into school you can select a jar made of glass or a coffee can (size: 10cm/4" dia. can) works well too. If you wish to make and see how a mercury type works using water instead of mercury,go to photos and docs and print out the instructions for: "liter bottle barometer." Your task (using either or both barometers) will be to: A. Make (keep at home) the barometer and B. record the pressure at home once daily for 3 days* onto the data table of the handout. * I'll tell you which days to record, while your in class and more will be explained in class. For a hard copy of this worksheet go to photos and docs. look for, "Working under pressure_making a barometer". If you have access to the online text, you can go to the weather book and under air pressure, look for the activity to make a barometer with video and worksheet. Any parent who wishes to register (son or daughter) for online text may do so by simply sending me an email with the name of your child and I'll forward you the registration form, so you can sign them up. Oct 26-28: Study for Quiz on Thurs. Quiz will be on Air Pressure. Your study guides include: the online study guide, plus your Air Pressure Notes, plus the Air Pressure - Questions sheet that has the 6 experiments/Demos we have done in class -last week and today. Also the online quiz might give you an idea of how well you know or don't know air pressure. (see Quiz challenge below) What you really need to know is WHY the experiments did what they did! Why the can got crushed when we put it into the cold water after heating it? Why the balloon inflated in hot water and deflated in cold? Why the liquid wouldn't come up the straw when the lid was on the jar? Why the cap popped up and down when you wrapped your hands around the bottle? Why the water stopped coming out of the bottom of the coffee can that had 3 holes in it, when I placed my finger over the hole in the lid. Why the water in the red cup, with the CD/cardboard on it, stayed in the cup when we turned it over? Why the piece of paper straightened out when you blew air over the top of it? Finally, be able to explain "How you know that air has mass and takes up space?" Remember all of these have to do with changes in Air Pressure. What is air pressure- Definition and how much does it weigh? Oct.22, 2009: "A Sucker's Bet" - Due tomorrow: Fri. Print out p.2 of this document. Read why you can't suck the fluid out of the container/jar after just a little comes out. Do NOT change your conclusion/answer after reading the reason. I want to see what you think the reason/conclusion is! Read notes and quiz challenge below. NOTE: Anyone who has signed up for online access to the texts should check out the Weather and Climate book online. For any parent who has not registered your child and would like to, please email me your request for a reg. form. State childs name on your email. NOTE: Studying and preparing yourself for the Air/ Air Pressure Quiz. You should be reading over the air pressure notes and be thinking about the experiments we are doing in class. (i.e what happens to air that gets heated- does it expand or contract?) Weather Quiz Challenge: Take the Quiz challenge: Go to the following web site: http://assignments.discoveryeducation.com/ and enter the following code # in the red box marked CODE: Q7461-EC6A (include the dash). Then enter your name in the box asking for Name. Click on the words: take Quiz. You can take the quiz as many times as you wish. Anyone who takes the quiz and gets a 100 and prints out proof of that (and Brings me the proof) will get a small prize. Note: this is for practice only and will not be graded or effect your grade in any way. This assignment is due Friday Oct.23rd. This should give you time to get your materials and try figuring out the answer without reading it. Good Luck!! and enter the following code Wed: You have until thursday night to complete the Sucker's Bet HW. Worksheet with your answers will be collected in class on Friday Oct 23rd. Tuesday Oct 20, 2009: Try this experiment: "A sucker's bet." Try this at home with Mom or Dad's help. There is a 2 page worksheet in photos and docs, that tells you what you need to do and what materials you'll need to do it. The second page has the answer; Have Mom or dad hold onto the answer sheet until you try the experiment and have attempted to answer the conclusion. If you really need help Mom and Dad can offer some. But I hope you'll be able to figure it out first. This assignment is due Friday Oct.23rd. This should give you time to get your materials and try figuring out the answer without reading it. Good Luck!! Monday Oct. 19, 2009: Print out (from Photos and docs) and read through the air pressure notes page and have it for class on Tuesday. Due Fri Oct 16, 2009: Look up (google SDO) the name of the sun satellite that will launch in November, 2009. Abbreviation SDO. What does S.D.O. stand for and what will it do/What's its mission?
