INPUT ARTICLE: Article: Your chart should have rows for each date that you measure your leaves. The columns should be labeled “number of leaves,” “average length,” and “average width.” You should check your leaves every two to three days. Be extremely thoroughly, but make sure you do not count the same leaves twice. Include new leaf tips and sprouts in your count. Record the number of leaves down in your chart. Choose a random sampling of four or five leaves. Hold the ruler from the bottom to the tip of the leaf. Add up the measurements, and divide by the number of measurements you took. (For example, if you measured by five leaves, divide by five). This is the average leaf length for that day. Record this down in your chart.  Repeat this process to find the width of the leaves. Measure the leaves at their widest part. Be as specific as possible; get the measurement down to centimeters and millimeters if you can. Keeping the leaf on the plant, draw around the leaf on grid paper. The grid should have squares that are one inch in area. Count the number of squares covered to get the surface area of each leaf. Leaves can grow quickly. Check the size of your leaves every few days to see how they are growing. You can use a modification of the growth rate formula for this purpose.  You can calculate the leaf number growth rate. This modification of the growth rate formula will tell you how many leaves are approximately growing per day. The equation for this growth rate is (L2−L1)T{\displaystyle {\frac {(L2-L1)}{T}}}where L1=first leaf count, L2=second leaf count, and T equals the number of days between each. The leaf size formula is the same as the plant height formula. Instead of height, the variable is the surface area. The equation for the growth rate formula is (S2−S1)T{\displaystyle {\frac {(S2-S1)}{T}}}where S1=first surface area measurement, S2=second surface area measurement, and T equals the number of days between each. Once you have gathered a few weeks’ worth of leaf tracings, you can use those shapes to create a template. Take a piece of paper or cardboard. Take the smallest tracing, and create a circle roughly that size, starting from the bottom of the paper. Create up to six larger circles that contain all of the measurements up to the largest. These should form concentric rings outside of the first circle. Label each of these circles with a number. One should be the smallest and six, the largest. In the future, you can use this template to measure leaves with greater ease. Hold up the leaf at the bottom of the paper with it centered around the smallest circle. Mark the largest circle it fills without going over and record that as the leaf size.

SUMMARY: Create a chart. Count the leaves on your plant. Mark the length and width. Trace your plant's leaves on grid paper. Repeat measurements every two or three days. Create a growth template.


INPUT ARTICLE: Article: You can print fingerprint cards from free online images. Try this one used by the FBI and other US agencies. Position the card on a special stand, or just weigh it down with a heavy object to stop it sliding. If you are taking fingerprints for an official purpose, you may need to find a fingerprint card you are authorized to use. Even if your agency is authorized to use the card linked above, it should order it using these instructions on the FBI website. Have the subject wash and dry his hands to remove dirt that may obscure the fingerprints. Check the hands for lint from the towel, and ask him to brush it off if present. If soap and water are not available, rubbing alcohol is the second best option. Have the subject sign the card before washing his hands. Use blue or black ink. The subject does not fill out his own fingerprint card. You, the person tasked with taking the fingerprint, will do it for him. Hold the base of the subjects thumb, tucking unused fingers under your hand. With your other hand, hold the subject's finger just below the nail tip, and at the third joint.   Keep the wrist level with the hand. If possible, move the fingerprint station to a height level with the subject's arm. Ask the subject to look away if they seem to be "helping;" the fingerprint will be more clear if only you are controlling the hand.

SUMMARY: Set up the fingerprint card. Clean hands. Grasp the subject's hand.


INPUT ARTICLE: Article: Dwarf cannas grow to about three feet tall. They come in a variety of colors, such as the bright red Ambassador or the City of Portland, which is known for its salmon color. Regular cannas are much larger in size, so dwarf cannas tend to grow better when potted. Potted cannas will grow in almost any potting medium that can be purchased at a garden supply store--they’re really not very picky. However, it must be soil that drains well, as cannas don’t do well with soggy roots and could develop mold. You will also have to choose your container based on the size of the variety of canna you are choosing to plant. If you are not sure how large your specific canna can grow, run an online search or ask someone to help you at your garden supply store. Remember, you can plant your cannas with other plants in your container, but just remember that all of the plants in one container must have the same water and sunlight needs or else they will not do very well. Plant your rhizomes (or tubers) in these holes, making sure that each dwarf or medium rhizome is at least 1 foot (.30 m) away from the next rhizome, unless you are planting them in a container, in which case you can often fit two or three tubers in a container. If you have a larger variety of canna rhizome, make sure that there is at least 2 feet (.61 m) distance between rhizomes. Make sure that the growing points (or eyes of the tuber) or pointing up. You should water your cannas right after you plant them so that the soil will settle around them and they can start to grow. When they have begun to sprout, water your plant as much as needed, keeping an eye on the soil to make sure that it is always relatively moist (though not soaking wet). It is recommended that you bring your cannas outside so that they can get full sunlight during the warm months. If you do choose to keep them inside, make sure they are near a window that provides them with bright sunlight for most, if not all, of the day. If you did bring your cannas outside for the summer months, make sure that you bring them back inside before the first frost has the chance to harm them. Store them indoors where the temperature stays at around 45 and 60 degrees F (7.2 to 15.5 degrees C). You can also dig up the rhizomes and store them in a plastic box with peat moss or perlite.

SUMMARY:
Consider buying dwarf cannas for your planter. Use well-drained, good quality soil. Purchase a pot with drainage holes. Dig holes that are 4 to 6 inches deep (10 to 15 cm). Water your cannas. Make sure your potted cannas get plenty of sunlight. Bring your pot inside before the first frost.
