    Barstow Science Lab

    7th and 8th Grade General Science - 

    8th grade, Science Museum April 10th!!!  You should be making forward progress on you science museum exhibit - Hands-on activity for younger students, research how/ why it works, visual display explaining the science behind your activity. 

    7th Grade - April 1 Chemistry Quiz (be sure to study Conservation of mass, the 3 types of bonds, four clues that a chemical reaction has occurred, Crystallization, Chemical reaction, and atom parts)

    Feb 28th - "How do you know a chemical reaction has occurred" paragraph due


    Atomic structure Quiz - Tuesday Jan, 21

    Jan - Structure of atoms 

    The ATOM MODEL PROJECT has been assigned!! Choose any atom you like - Build one or draw one, Write a story or a paragraph about ions. Click here for the assignment details

    Here is the copy of the atoms notes:

    The atomic structure quiz has been moved to Tuesday, Jan 21. Use your study guide, play the Phet simulation, and don't forget to look at you elements every day!!!

    Try out this game to review and reinforce the atomic structure.

    Quiz on atomic structure Jan 16th - 

    Atomic structure - parts, sizes, location and charges. Also Isotopes and ions. 

    Take a look at the TED-ED "How small is an atom?" https://www.youtube.com/watch?v=yQP4UJhNn0I

    Check this one out, too https://www.youtube.com/watch?v=uaGEjrADGPA

    Dec - The periodic table of element

    Explore the elements and the layout of the table. What makes it periodic? Why is in in the shape that it is? 

    Predict the properties of unknown elements based on the location on the periodic table -  Just like Demitri Mendeleev did.

    Nov -

    Atoms and the Periodic Table of Elements     

        The evolution of the atomic model  - Democritus, John Dalton, JJThomson, Ernest Rutherford, Niels Bohr, James Chadwick, and Ernest Schrodinger

    Elements of the periodic table - Which elements are you familiar with and what are the patterns that can be diserned. 

    The parts of an Atom - Protons, neutrons, electrons; their charges, locations, and sizes

    The atom model project - Build a model of an atom.  Design an advertisment for your element including uses and sources

    Dec - Feb

    Chemical Reactions

    What are the clues that a chemical reaction have occured? Students will be working through a series of four mysteries designed to wrestle with the ideas of chemistry.

    Jan and Feb 

    Energy - How do we turn energy into electricity that people use? and what are the consequences of our energy usage? Students learn how to make electricity from other forms of energy and discuss the pros and cons of each source of energy: Hydro, wind, nuclear, solar, coal and other fossil fuel 

     Feb - April break 

    The SCIENCE FAIR 

    Students will be designing their own science fair project using the scientific method.  The culminating event will take place just before April break and will give an opportunity to share the information that the student learned with the community. 


    April break - May 7

    Students reviewed content areas that were taught from 5th - 8th grade. They learned strategies for taking NECAP style tests. 

    1. Underline key word - helps to focus on the important parts of the question, highlights what the question is asking and indicated is the question has two parts

    2. Use process of elimination - crossing off the one or two answers that are obviously wrong will help if you need to guess at the correct answer..

    3. Diagram - for constructed response question using a labels diagram to help support your answer is accepted and encouraged.

    4. Restate the question as you begin constructed response answers. It helps you to focus on the important words if you restated them and may clarify what the question is asking. 

    May - June 

    Properties of Matter

    Scientist have lots of ways of describing and measuring the objects that make up out universe; density, volume, mass, melting and boiling point, electrical conductivity and more. For this unit we have a series of mini labs each designed to give students an opportunity to solve a problem, examine one particular property, and apply it to something in their own lives.
