Experiment 1: Observation of Mitosis in a Plant Cell
In this experiment, we will look at the different stage of mitosis in an onion cell.
Remember that mitosis only occupies one to two hours while interphase can take
anywhere from 18 - 24 hours. Using thi
Experiment 1: Testing for Proteins
The protein molecules in many foods provide the amino acid building blocks required by our
own cells to produce new proteins. To determine whether a sample contains protein, a
reagent called Biuret solution is used. Biur
Experiment 1: Tonicity and the Animal Cell
In this experiment you will explore the effects of osmosis on eggs. An egg is surrounded
by a permeable membrane and a hard shell. To observe the effects of osmosis the shell
will first need to be removed.
Experiment 2: Tonicity and the Plant Cell
Plant cells are able to generate osmotic pressure while other cells cannot. This is due to
specialized plant structures such as the cell wall which prevent lysis caused by osmosis.
By taking advantage of this syst

Experiment 1: Enzymes in Food
Amylase is used by humans to facilitate digestion. Specifically, it is an enzyme which
breaks down starch molecules into sugar molecules. This is why people sometimes
observe a sweet taste after sucking on a starch-containing
1. How could you test to see if an enzyme was completely saturated during an
experiment? If an enzyme was consumed, the reaction isnt happening anymore. You
could look at it to see if a reaction is still happening.

Experiment 1: Slime Time
Inks can be polar or non-polar. Polar solvents pick up polar inks, while non-polar solvents
pick up non-polar inks. In this experiment, you will use inks to identify slime and silly
putty as polar or non-polar. You will also use p
1. Nitrogen fixation is a natural process by which inert or unreactive forms
of nitrogen are transformed into usable nitrogen. Why is this process
important to life?
It is important because many organism needs nitrogen for it survival.
By growing five cups of grass seed in five separate colors of light, we learned that the plants in
the black light grew the worst, and the plants in the white light grew the best.
