Q: In order to complete your studies in a reasonable amount of time, it’s helpful to draw up a loose schedule of when you will do each experiment. Keep in mind that many experiments will not work the first time and you will have to repeat them to make sure the data is consistent.  Use a weekly or monthly calendar to schedule experiments, including time for analysis and interpretation of results. As you continue through experiments, some conditions may change or perhaps you will end up going in a different direction. This is normal, just be flexible with your schedule. During the design phase, you will have written up a detailed protocol that should include all of the solutions and components needed to perform the experiment. Using this write-up gather everything you will need. Make sure to sign up to use shared equipment in advance so it will be available to you when you need it. Do as much of the small stuff as possible the day before such as labeling tubes and making solutions. The day of the experiment, use your detailed protocol and follow the instructions closely. If you deviate from the written protocol at all, make sure to note what you did that was different. Keeping a lab notebook with all of your experiments and results is essential to conducting research.  The first time you do an experiment, it is extremely likely that you will make mistakes or things will go wrong. This is totally normal. Take notes and learn from your mistakes for the next experiment. Record your results in your laboratory notebook. If the data you obtained from an experiment indicates that the experiment itself didn’t work, you will need to troubleshoot it and figure out what went wrong. There are a number of factors that can contribute to an experiment failing:  If you were using a special kit from a company, contact them or seek out their troubleshooting information. Make sure all of the reagents used were not past their use-by date. Check to make sure all of your instruments were working properly that day. Double check all of your calculations and make sure the proper amounts and solution concentrations were used. Once everything has been optimized and troubleshooted, you will simply need to repeat the experiment until you have the correct number of data samples to analyze as determined before in the design phase. After collecting all of the data, you can analyze it and start drafting a manuscript for publication. Use all of the same reagents and instruments whenever possible to limit variability between experiments.
A: Plan your experiments. Gather the necessary materials. Perform the experiment. Troubleshoot the experiment. Repeat the experiment.

Q: Place the fitness ball on a wall behind you. Stand with your legs about shoulder-width apart, and lean back against the fitness ball for support. Slowly bend your knees and lower your tailbone until you are almost in a sitting position. Hold the pose for 10 seconds and slowly return to a standing position.  Perform several 4-5 sets of 8 to 10 repetitions. When doing these wall squats with the fitness ball, position the ball low enough against your body that it will still offer you full support once you are in a squatting position. Start with your feet far enough from the wall so when you squat, your knees are above your ankles and not your toes. Stand with your feet planted out past each side of your body, leaning with your back against the fitness ball. Your feet should be about 4 feet (1.2 m) apart and your torso should stay upright. Lower your body slowly, supporting your weight in your quadriceps and glutes, and hold the pose for 10-12 seconds. Stand up slowly and repeat. As with traditional squats, try doing 4-5 sets of 8-10 repetitions each.  To prevent injury, do not extend your knees past the tip of your toes when bending into position for squats. Make sure your knees are above your ankles, not your toes, as you complete the squat. As with wide-stance squats, place the fitness ball on the wall behind you. Stand with your legs close together and with your back against the fitness ball on the wall. Your legs should only be slightly narrower than your hip width. Bend your knees and lower your body to nearly a 90-degree angle. Hold for 10-12 seconds and slowly return to standing position. Keep your torso upright and your back straight. Do 2-4 sets of 7 to 9 repetitions. As your quads strengthen, you'll be able to increase the number of sets and reps that you can do.
A:
Perform traditional squat moves for the quadriceps. Practice wide-stance squats to strengthen your inner quads. Do narrow-stance squats to strengthen your outer quads.
