Description |
|
1 |
Usable Water |
Students clean a dirty water sample by using various filtration methods. |
|
2 |
Mixtures |
Students observe 4 samples (solutions & suspensions). Perform Tyndall effect
test and filtration test. |
|
3 |
Water Testing |
Students test for the presence of ions in tap water. Use a reference
solution for positive test and control (distilled water) for negative test. |
|
4 |
Solvents |
Students mix 7 solutes into 2 solvents (water, hexane) to test their
solubility. |
|
5 |
Water Softening |
Students use four methods to soften water and test the results by mixing
with sodium carbonate and by using soap. |
|
6 |
Resources: Chemical Reactions w/Metals |
Students use 3 pennies to to perform different chemical processes. The
copper in the penny combines with zinc to make brass. |
|
7 |
Metal/Nonmetal |
Students test 7 unknown elements to determine if the sample is a metalloid,
non-metal or metal. Tests: malleability, conductivity & chemical reactivity. |
|
8 |
Metal Reactivity |
Students test 3 metals (copper, magnesium, zinc) to see how they react with
ionic solutions. |
|
9 |
Producing Copper |
Students produce copper from copper sulfate solution by means of
electrolysis. |
|
10 |
Viscosity |
Students determine density and viscosity on 6 petroleum-based materials and
water. |
|
11 |
Combustion |
Students determine the heat of combustion of a candle (paraffin wax) by
heating up water. |
|
12 |
Hydrocarbons - Esters |
Students produce esters (artificial fragrances) from alcohol and acids. |
|
13 |
Polymers/ Synthetics |
Students make nylon cord from mixing two chemicals. |
|
14 |
Milk Analysis |
Students remove the milk protein from a sample of milk and allow the protein
to air dry overnight |
|
15 |
Milk Analysis (continued) |
Students use milk protein sample from lab#15 and determine the percent
protein, water and carbohydrate and determine calories for milk. |
|
16 |
Vitamins |
Students determine vitamin C content of various beverages. Perform
titration. |
|
17 |
Iron in Foods |
Students determine iron content of food samples. Perform serial dilution. |
|
18 |
Radioactivity |
Students expose nature print paper by using radiation from various sources. |
|
19 |
The Unseen Atom |
Students guess at contents of mystery box. A.5 p281 Students determine
makeup of 10 pennies (pre/post 1982) in a film canister. |
|
20 |
A Radiation Detector |
Students build a petri dish cloud chamber to detect radiation. |
|
21 |
What's in the Air We Breathe? |
Students generate oxygen and carbon dioxide and perform tests on the gases. |
|
22 |
Temperature - Volume Relationships |
Students use a capillary tube with an oil plug to study temperature-volume
relationships of gases. |
|
23 |
Carbon Dioxide Levels |
Students use bromothymol blue to test carbon dioxide concentrations in three
air samples. |
|
24 |
Acid Rain |
Students burn sulfur and mix with water to make acid rain. They observe the
effects of acid rain on plant (apple), animal (protozoa), metal and marble. |
|
25 |
Enzymes |
Students test how well enzymes (pepsin, amylase) work on albumin and starch
and respond under varied conditions (room temp., refrigerated & buffered pH of 4,
7 ,10) |
|
26 |
Buffers |
Students compare adding (acid/base) to water with adding (acid/base)
buffered solution. |
|
27 |
Sunscreens |
Students test how well sunscreens with varying SPF's work by exposing nature
print paper and using the sunscreen to filter out sunlight. |
|
28 |
Electrochemistry |
Build and test different
electrochemical batteries to determine which will generate the most voltage. |
|
29 |
Smoking |
Students use smoking machine to make tobacco water and test the effects on
protozoa. |
|
30 |
Fertilizers |
Students test for the presence of anions and cations in two unknown
fertilizer samples. |
