WAX FLOWER

Classification: (Note: for Hoya Carnosa, same family as Hoya Kerri, since no available information on Hoya Kerri.)

 * Domain
 * Kingdom - Plantae
 * Phylum
 * Class - Magnoliopsida
 * Order - Gentianales
 * Family - Asclepiadaceae
 * Genus - Hoya R. Br. (?)
 * Species - Hoya Kerri 'Variegata'

Geographical Location: Daily care:
 * Native to Thailand, Indonesia and Malaysia
 * Likes bright areas without direct sunlight
 * Enough water to wet an inch of soil, but only when soil is dry (make sure soil is not wet from last watering)

Other interesting information:

 * Slow-growing
 * Poisonous sap
 * Produces up to 10 flowers
 * ~ Dependent Variable ||~ Measuring Device and Units ||~ Uncertainty of Measurement ||
 * length of the one leaf || ruler - cm || 0.02+/- cm ||
 * weight of plant || balance, graduated cylinder - grams (subtract mass of water added by week) || 0.02 +/- g (?) ||
 * plant leaf inclination || ruler, graph paper - cm || 0.04 +/- cm ||

Expectations: Length of Leaf - I except the leaf to gradually grow only the slightest bit over the three months as it is already practically full grown. However, if there are any new sprouts within the first two months, I will start to calculate their length as well since it may be more productive and interesting than measuring the one grown leaf.

Weight of Plant - I do except the weight of the plant to change more significantly than the length of the leaf due to the greater possibility of added weight from more roots or leaves. Over the three months, I think the weight will be recorded as slightly linear on a graph. (In a flat slope that rises little over time)

Plant Leaf Inclination - For this test, I will have to set a up a graph paper showing the distance so I can accurately calculate the "inclination" of the tip of my plant's leaf. (The "inclination" of my plant is the direction/distance it moves from one side of the pot to the other, should be depended on the sun.) I don't think my plant will move that much but the results still have a good chance at surprising me.

Experiment:
For my experiment, I would change the plant's water color by using food coloring. I would watch for any change in the plant's leaves from green/yellow to the color I chose from the coloring. I would decide an average amount of water to give to my plant every other day. I would record this information and each time I water my plant, along with a short description of any or a lack of change in my plant's color.
