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 (L2L1)T{\displaystyle {
rac {(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 (S2S1)T{\displaystyle {
rac {(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.

Team sports encourage friendly competition and help students cooperate and work together toward a common goal. Students can learn how to positively communicate with each other in a social setting while also running, jumping, and playing. Activities such as hockey, soccer, flag football, softball, and basketball are very popular in PE classes. You can spend a few weeks on each sport, or pick just 2-3 to focus on during the year. Individual activities that don't require a team, such as yoga, weight training, golf, frisbee, and aerobics, tend to stick with children into their adult lives. This is a great time to teach them the basics in a safe and supportive environment, to foster enjoyment of these activities that will last a lifetime. In large classes, breaking into multiple groups of five or six students to learn the fundamental skills of a sport or activity will help improve physical skills, social skills, and teamwork. You can have each group doing a specific activity at a station, and have them rotate every 10 minutes or longer. This provides variety and will help to keep students engaged. A well-designed curriculum will have activities that accommodate all student needs. You can include activities that are inclusive to students with different needs while still challenging more athletically-inclined students. For example, an activity such as yoga increases mobility, hand-eye coordination, and flexibility, but can be adjusted to be more or less challenging for individual student needs.

Summary: Allow children to participate in team sports. Incorporate individual activities into the curriculum. Set up stations for small groups. Plan inclusive activities for all students.

Becoming a rock singer requires more vocal control than singing karaoke in a bar. You need to learn how to control the pitch and tone of your voice. Sing from the stomach instead of the throat. Singing from the throat is like a speaker without a box. You don't get the fullness of the sound. It will sound squeaky when you try to hit some good notes, especially the high ones. So, mainly use the throat as a conduit. Work on hitting high notes. Diaphragm pressure is the key to creating the heavier vocals used by rock singers. Your diaphragm controls the air that goes through your vocal chords. Some pressure in your diaphragm can push just enough air through your vocal chords to get that heavy grit out. Practice changing the pitch. Experiment with opening and closing your throat, lips, and teeth to see how much control you have over the sound. Closing your throat can add harshness or grit, while opening it can increase volume and improve timbre. Lips and teeth affect not only the character (what phonics you make) but also how the vibration of your vocal chords is translated into the air around you. As you become more controlled and proficient in using your voice, try to expand your musical vocabulary by learning about the basics of music and singing. Vocal warm-ups, scales, intervals, and timbre are all helpful things to familiarize yourself with but remember the first rule of rock: do it your way. Choose your style of rock. Abandon musical lyricism, tone, and articulation. Rock singing should be rather ambiguous in rhythm, lyrics, and pitch. That is the essence of hard rock. Don't try to learn from a cd or machine. Get a great teacher. Many professional rock singers have done so. A voice coach will help you develop your voice and can give you tips in how to protect your voice. Rock has a vast array of voice styles and methods. An experienced coach can appropriately assess your improvement. A coach will help you improve your vocal range. There are no shortcuts. It takes a long time to learn to sing well. You might have natural talent, but that will take you only so far. You have to have a solid technique to have a stable career. That is why there are so many "flash in the pan" performers. They have no technique, and their voices crash and burn quickly. You do have to be able to hold enough breath to push a note loud enough for a microphone or audience to hear it. Focusing on core exercises such as abdominal, chest, and back muscles will help you tighten your core in order to focus on your breath. Cardio exercise such as biking, jogging, jump rope, and even brisk walking can improve the amount of breath you have for holding notes and can also help a lot if you're an active singer who does a lot of jumping around or headbanging while singing. Take care of your voice. While some singers can smoke and drink and sound like rock stars, that approach might not work for you. It's important to know the limitations of your own voice because nothing is worse than running your voice ragged before your band finishes its first set. Everybody has a different vocal range, but most male singers fall into the categories of either bass, baritone or tenor, while most females have either a contralto, mezzo soprano or soprano vocal range. Some people have ranges that extend further than these categories. Learning your vocal range is very important because you need to know your limits. Learn how to scream. Develop a screaming-yelling style to your singing voice. Most rock singers do not utilize the same technique as pop stars do: instead of smooth transitions and mild sounds, they go for the more scream-like voice, making it sound more passionate. Try yelling parts of any rock lyrics without utilizing vocal notes and then replicating that feeling while singing.
Summary: Learn how to control your voice. Study the fundamentals of rock music and singing. Get a voice coach. Exercise to strengthen your voice. Learn your vocal range.
