Alien Invasion | ![]() |
Help! Aliens have landed on Earth from another planet. Before scientists can release the aliens, they want to identify and classify them. Use the dichotomous key on the next page to identify these creatures.

Alien Taxonomy | ![]() ![]() ![]() |
In the year 2525:
Humans, after hundreds of years of constant effort, have successfully polluted all bodies of water on Earth. As a result, almost all previously known species of plants, animals, and other life forms have become extinct. Through natural selection, genetic engineering, and selective breeding programs, a portion of the Earth has been successfully repopulated. The following organisms are all that remain:
Your Assignment:
As an alien taxonomist, it is your responsibility to classify these existing organisms.
Enzyme Amylase Action on Starch |
INTRODUCTION:
In this experiment you will observe the action of the enzyme amylase on starch. Amylase changes starch into a simpler form: the sugar maltose, which is soluble in water. Amylase is present in our saliva, and begins to act on the starch in our food while still in the mouth.
Exposure to heat or extreme pH (acid or base) will denature proteins. Enzymes, including amylase, are proteins. If denatured, an enzyme can no longer act as a catalyst for the reaction.
Benedict’s solution is a test reagent that reacts positively with simple reducing sugars like maltose, but will not react with starch. A positive test is observed as the formation of a brownish-red cuprous oxide precipitate. A weaker positive test will be yellow to orange.
MATERIALS:
Cornstarch Distilled water Saliva Vinegar Benedict’s qualitative solution 3 graduated cylinders (10mL) 250-ml beaker Stirring rod 3 test tubes (16 x 125mm) Test tube rack Wax pencil Water Bath | ![]() |
PRE-LAB:
Add 1g of cornstarch to a beaker containing 100ml of cold distilled water. While stirring frequently, heat the mixture just until it begins to boil. Allow to cool.
PROCEDURE:
1. Fill the 250-mL beaker about 3/4 full of water and place on the hot plate for a boiling water bath. Keep the water JUST AT BOILING.
2. Mark 3 test tubes A, B and C. “Spit” between 1 and 2 mL of saliva into each test tube.
3. Into tube A, add 2 mL of vinegar. Into tubes B and C, add 2 mL of distilled water. Thump the tubes to mix.
4. Place tube B into the boiling water bath for 5 minutes. After the five minutes, remove from the bath, and place back into the test tube rack.
5. Add 5 mL of the starch solution to each tube and thump to mix. Allow the tubes to sit for 10 minutes, occasionally thumping the tubes to mix.
6. Add 5 mL of Benedict’s solution to each tube and thump to mix. Place the tubes in the hot water bath. The reaction takes several minutes to begin.
OBSERVATIONS:
Tube A: Starch + saliva treated with vinegar (acid)

Tube B: Starch + saliva and water, treated in a boiling water bath
What does this indicate?__________________________________________________
