NOTES ON LABORATORY EXERCISES:

Chemistry and Biology will have double periods scheduled once a week to permit two-period labs in each subject.

Note A: Reactions like starch + iodine (color changes), acids and carbonates (bubbling), precipitation of BaSO₄ or AgCl.

Note B: Impurities to include cornstarch, sugar, salt, methylene blue. A distillation apparatus may be set up in a central, public place to run (with supervision) throughout the morning or all day. During their next lab period, students can test both the initial impure solution and the distillate.

Note C: Water & dilute acids (HCl, sulfuric, vinegar) tested with the following: salt, baking soda, limestone, iron, aluminum, sulfur.

(All labs are tentative and subject to change.)

OTHER POSSIBLE LABS, including FUTURE YEARS:

Simple combination and separation reactions (?)

Measurement of melting points and boiling points.

Electroplating of copper (?)

Generating oxygen; properties of oxygen.

Gas laws

Equilibria

Rates of reactions

Properties of metals

Precipitation reactions

Freezing point depression

Calorimetry, specific heat

Heat of fusion of ice

Serial dilutions; spectrophotometry if possible

Testing for selected ions: NH₄, S, SO₄, Cl, etc.

Chemistry and Biology will have double periods scheduled once a week to permit two-period labs in each subject, as needed.
