You can find these magnets in the magnet section of a hardware store or a craft store.  They are typically sold in packs of 6 or 8. If you cannot find any, get a set of magnetic jewelry clasps from the beading section of a craft store instead. You can use smaller magnets too, but don't use larger ones. Do not use the  standard "black" magnets either; they are not strong enough.

Summary: Get a pair of 1⁄4 in (6.4 mm) silver neodymium magnets.


Don’t settle on simple tongue twisters for kids. Look for the longest, most difficult tongue twisters you can find. Select a number of tongue twisters that focus on different letters of the alphabet. Try out something like this: "I'm not the pheasant plucker, I'm the pheasant plucker's mate, And I'm only plucking pheasants 'cause the pheasant plucker's late. I'm not the pheasant plucker, I'm the pheasant plucker's son, And I'm only plucking pheasants till the pheasant pluckers come." Focus on the enunciation of the words. Pronounce each syllable clearly and as quickly as you can. This will help loosen up the muscles in your tongue so you can speak at a faster rate. This exercise will improve your breathing so you can use better technique when rapping. It can also help improve your lung capacity. This is important to being able to rap fast because it teaches you to say more words with each breath.  If you can't say the tongue twister in a single breath, try some additional breathing exercises to get you there. Hissing is a good beginning breathing exercise. Breathe in to the count of 4. Breathe out, hissing, to the count of 4. Then, breathe in for 6, and hiss out for 10. Breathe in for 6, out for 12. Breathe in for 2, out for 12. Breathe in for 4, out for 16. Breathe in for 2, out for 16. Breathe in for 4, out for 20. Breathe in for 1, out for 20. When you accidentally mess up, start over until you get it perfectly. You want to get it right the first time and every time. When rappers perform live, they only get one shot at getting it right. Mistakes are bound to happen, so don't beat yourself up over it. Just keep working to minimize their frequency. Try this exercise for 5 to 10 minutes a day to practice your technique and build speed. If you want you can time yourself to see how much faster you are getting over time.

Summary: Look up some difficult tongue twisters. Read the tongue twister out loud. Say the whole tongue twister in a single breath. Eliminate your mistakes. Repeat the tongue twister faster.


If you fear being alone at night because of someone breaking in, because of a medical emergency, or because of a disaster like a fire, taking measures to ensure your safety will help ease some fear. You can take practical steps to prepare yourself in case an emergency occurs.  Lock all doors and windows before going to sleep Familiarize yourself with fire escape routes Consider getting a security alarm Make sure you have a working, charged phone nearby Take a self-defense course Know who to call in an emergency It's easy to give in to your fears and imagine the worst-case scenario when you're at home alone. You may be tempted to keep the lights on, keep the TV on, always invite a friend over at night, or compulsively check your locks before you go to bed. These ritualized behaviors will increase your anxiety about being alone at night in the long-run.  Avoid asking someone to come stay with you too often Find rational explanations for noises you hear in the middle of the night Wear earplugs or use a sound machine to block out strange sounds Go to counseling if you start to obsess over your fears or if they interfere with sleep Getting to know your neighbors is a good way to make sure other people know who you are and can keep an eye out for you. Befriending your neighbors is good for social connection, too! You might meet other people who live alone and set up a system where each of you agrees to check up on each other if you haven’t heard from each other in a few days. While you can learn to cope with any loneliness and frustration of being alone, there are some instances where being alone may start to be unsafe for you. This is especially true if you are an older adult or have any chronic health issues. Reach out to a trusted friend, loved one, or physician for help if you have:  Difficulty managing your medications Difficulty paying your bills Difficulty bathing Difficulty eating well Difficulty with balance and falls Difficulty keeping your house clean Difficulty getting out to connect with other people

Summary: Ensure your safety. Confront your fears. Befriend your neighbors. Know when to seek help.


Once you have finished the planning phase, you should be able to create your model. Use your diagram, data, and other information to make your mathematical model. Make sure to check your notes often to ensure accuracy.  Make sure that your model represents the actual relationship among your data that you are trying to accomplish. For more advanced models, you may need to use a computer program. It is important to verify the validity of your model’s results before you try to do anything else with your model. Apply your data and see if the model is valid. Are your results what you expected? Do they make sense? Are the results repeatable?  Solve the equation V = h x w x l to determine if your results make sense. Repeat the solution to determine if your results are repeatable. In order to make your model useful for further applications, you need to consider how it could be improved. Are there any variables that you should have considered? Are there any restrictions that could be lifted? Try to find the best way to improve upon your model before you use it again.  For example, if you want to have 3 feet (0.91 m) of space to walk through your storage unit, you could adjust your equation to account for that space. Just deduct the space you will lose from the appropriate number in your equation. In this case, you could adjust your equation to read V = h x (w-3) x l  After you have identified ways to improve your model, make the changes and test it again.
Summary: Create your model. Test your model. Determine how the model could be improved.
