General Science





1.  Do TWO of the following:

     [a]  Chart the motion of the Moon and one planet during

           4 hours.  Relate this to a point on the horizon.

     [b]  Chart the position and appearance of the Moon on the

           days or nights you can see it for 28 days.

     [c]  Chart the positions of three constellations and the

           North Star during 4 hours.  Relate to a point on

           the horizon.

     [d]  Watch the report on an eclipse of the Moon, a meteor

           shower, or similar astronomical event.



2.  Describe your findings after checking TWO of the following:

     [a]  The erosion during a month's time of one of the following:

           A stream's banks.  A tract of land from which the

           vegetation has been removed recently.

     [b]  An exposure of a rock stratum or strata.  This could be

           at a natural canyon or river gorge.

     [c]  The appearance of three different kinds of clouds in the sky.

     [d]  The environmental conditions which come before and during

           three different kinds of precipitation.

     [e]  The changes in the looks of three different kinds of

           rocks or minerals after being freshly broken and the newly

           exposed surfaces allowed to weather for a month.



3.  Describe what you learned after watching TWO of the following:

     [a]  The germination of three different kinds of seeds.

     [b]  The metamorphosis of an insect.

     [c]  The parts of one flower before and after pollination, and

           some time before the seeds are ripe.

     [d]  The buds of five kinds of trees while dormant and after

           partial opening, either natural or forced.



4.  Build models or show the basic scientific principals or ideas

     that are applied in FIVE of the following:

      [a]  Using lenses to make a telscope or compound microscope.

      [b]  Making a dry cell or other kind of electrical "battery."

      [c]  Extracting a metal from its ore.

      [d]  Getting crystals from a solution of a substance.

      [e]  Lifting something too heavy to lift directly.

      [f]  Making a magnet that can be "turned on and off."

      [g]  Using materials that are more dense that water to build

            something that will float.

      [h]  Shaping an airplane wing so it will lift a plane.

      [i]  Changing back-and-forth motion to rotary motion.

      [j]  Generating carbon dioxide so that some kinds of baked

            foods will "rise."



5.  Design, carry out, and report on or show FIVE experiments that

     will:

     [a]  Show the change in volume of salt water above and below

           freezing temperature.

     [b]  Show that the composition of the air in a bottle has

           changed when a bottle is placed over a burning candle

           until the candle goes out.

     [c]  Show what happens when new seedlings are badly crowded

           in a pot of soil.

     [d]  Show the effects of rusting tendency on an iron nail placed

           in a jar of water when different metals are wrapped around

           the nail.

     [e]  Find out how the strength of an electromagnet is changed

           by the number of turns of wire and the current.

     [f]  Show the effect of available water on the root development

           of seedlings.

     [g]  Compare the orientation of a plant grown in complete

           darkness with one that was grown in light.
