  2. 7th Grade extra credit project
    The seventh graders have the option of creating an electrical quiz board as an extra credit project. An electrical quiz board uses separate circuits to create a matching game in which only correct matches will light a bulb or make a buzzer work. See links below for examples and tutorials.

    Students can earn up to 5 extra points added to their grade for the quarter in science class. To get full credit, the quiz board must have at least 8 different terms and their matching phrases or pictures. The matching questions may cover any academic topic. For example, match a composer to a piece of music, match a Spanish word to its English translation, or match a state to its outline.
    Project is due March 17th.

    Remember that this will not be enough to prepare you for the test on Tuesday. You will also need to understand Punnett Squares and pedigrees.

    This unit does not have as much vocabulary to learn as some of the previous units. Most of the test will determine whether the students understand how to use a Punnett Square and pedigree chart. They should practice with the ones we did in class and search for other practice examples online, such as these:

  6. Water Cycle definitions

    Evaporation – The process by which water molecules at the surface of a liquid change to the gaseous state.

    Transpiration – The process by which plants give off water vapor through their leaves.

    Condensation – The change of state from a gas to a liquid.

    Precipitation – Water that falls to Earth as rain, snow, hail, or sleet.

    Runoff – Water that flows over the ground surface rather than soaking into the ground.

    Freshwater – Water with very low levels of salt content.

    Groundwater – Water that fills the cracks and spaces in underground soil and rock.

  10. On Wednesday, December 9th, the second period science class got to have a Skype session with graduate students at UNC-CH and their scanning electron microscope. We were able to see images of samples that we had sent in about a week before the session. Here are images from the session that the graduate students sent to me. https://drive.google.com/folderview?id=0B_f-eRHacEIcYVRSamNqVC1lR1U&usp=sharing
    Ask you child to explain any pictures that you don’t understand.

  15. Protist extra credit project – Each student has an option to complete an extra credit project on a particular protist. Each student must pick a different protist. Here’s the list of which protists have already been claimed:

    You may make a model, create a webpage, a Prezi, or a Google Presentation. Let me know if you have something else in mind. I might approve that too!

    Some articles to consider:
    Australian article questioning why temperatures have not risen substantially for the past ten years.

    NASA article listing evidence of climate change: http://climate.nasa.gov/evidence

    NASA article outlining the consensus amongst climate scientists
    http://climate.nasa.gov/scientific-consensus

    Global Warming Petition Project: a site developed by people that don’t believe that we should worry about climate change:

  17. Extra credit project directions – In this optional project, students can build a circuit board “game.” The circuit board should work like one of the ones demonstrated in any of these examples:
    http://www.youtube.com/watch?v=z8wadyaIsy0
    http://www.usc.edu/org/edisonchallenge/2008/ws1/Matching_Game.pdf
    http://www.darkstar.cc/discovery/electricexam.htm
    The project is worth a maximum of 5 points added to your grade. To get full credit, your project must have ten questions and ten matching answers and it must work correctly. You must provide all of the supplies.
    Hint – make sure you pick a battery and bulb combination that will work. Too little or too much voltage for the bulb that you pick will cause the bulb to break or not light up at all.
    The project is due Tuesday, December 17th.
