Even if the jellyfish is dead, its poisonous cells can still cause a sting. Some varieties have very long tentacles (such as the Portuguese Man-of-War, that has tentacles up to fifty feet long), so it is best to stay far away from jellyfish. There are many different kinds and forms of jellyfish, and when they are washed ashore they may look like plastic bags or other debris. If you are not sure whether or not something is a jellyfish, it is best not to touch it at all. Tell a lifeguard or other beach authority when you spot a jellyfish on the shore, so that it can be safely removed by someone trained to handle the creature. Lifeguards are trained to help beachgoers in a variety of situations, including jellyfish attacks. They will also be able to alert you when jellyfish are spotted. If you shuffle your feet when walking in shallow water, you may disturb and drive away some jellyfish or other creatures that have the potential to sting you. Often, you can see jellyfish in the water. They may look like a plastic bag or balloon floating at the surface of the water, and may come in groups. If you see a jellyfish in the water, calmly but quickly return to shore to avoid stings. Tell a lifeguard or other beach authority when you spot a jellyfish in the water, so that a warning can be issued.

Article: In order to change your color selection, you will want to double-click on the color you wish to change at the bottom of the tool bar. This will bring up a window with several options, the clearest of which is to select the color you want from a mix of the box and the slider (both of which are largely self-explanatory). If you see a warning exclamation appear next to the color slider, it means that the color you have selected cannot print properly, though it should display on a monitor just fine. If you see a little box appear in the same area, this means the color you have selected will not display properly on the web. Select the "only web colors" box at the bottom if this is a concern for you. If you want to use a specific color, take note of it's hex code. This will be located near the bottom of the window and will be indicated with a pound or hash sign. Type in this code manually to change the color. This is a system of specifically numbered colors which correspond to inks used to print images. This is used mainly for print media to most accurately produce colors. Choose Pantone colors in Photoshop by going to the Color Library and choosing the appropriate number. Resources for and information about Pantone can also be found readily online, as it is the industry standard. You can also choose colors from the image itself by using the eyedropper tool. This can often be imprecise, however, so zoom in to your image for more control over the pixel color you are selecting.

Problem: Article: For any hair-straightening method you use that requires using heat to straighten your hair, it's important to condition it a few days beforehand. Heating dry hair will cause it to get brittle and may even make it break. Use a good deep conditioner on your hair about 2-3 days before you want to straighten it. Olive oil or coconut oil-based deep conditioners are great for your hair. Consider using these chemical-free options. You can also use a high-quality silicone-based conditioner a few days before you straighten your hair. Don't shampoo it, just wet your hair when you're ready to straighten it, and blot it with a towel until it's damp but not dripping wet. You're going to blow your hair dry piece by piece. Start with one section and use a round brush to brush it straight, starting at the roots and brushing all the way to the tips. Make sure it's tangle-free. Smooth it all over your hair, from roots to tips, to protect each strand from the damaging heat of the hair dryer. This will also help your hair stay straight for a longer period of time. Take your brush and position it at the roots of the section of hair you're blowing out. Turn on your hair dryer and position it right next to the brush, at the roots of the hair section. Move the brush and the blow dryer down the hair section to the tips, slowly drying and straightening the hair at the same time. Don't move down the shaft of hair too quickly; you want to do it slowly, so the hair has time to dry. Use either the warm or hot setting on your hair dryer for best effect. Repeat the process, section by section, until your entire head of hair is dry and straight.
Summary: Condition your hair. Get your hair wet. Brush out the first section. Apply a heat protectant. Dry the first section. Continue brushing and drying sections of hair.

Article: A classroom that feels tired probably won't be very inspiring. Take action to make sure that your classroom pulses with energy. Start by pumping up your own enthusiasm. Try not to come to class tired. Get up early in the morning so that you are fully awake by class time. If your students seem lethargic, try having them get up and move around. Even a quick stretch can wake people up. Students might feel more inspiration if they are having fun. Try organizing your lesson around a game. You can adapt this strategy for any age level. For elementary school kids, you could adapt the common game Simon Says. Students only get to move a step forward if they can correctly answer the math question, for instance. Try a version of Jeopardy for high school or college students. This quiz game is a great way to review for exams. Don't feel like everything has to be a game. They can be used every once in a while to insert some energy into your classroom. Each class is bound to have a few students who are reluctant to participate. However, it is important to make each student feel actively involved in the lesson. Try to get most (if not all) students to participate in activities. Some students may not like participating in group discussions. You might need to get creative to make it more appealing. Try a lightening round. Set a time limit (maybe 30 seconds) on each question. Make it seem fun and exciting to shout out the correct answer. Technology can be a great way to bring inspiration into your classroom. There are a number of tools you can use to get your students excited about whatever subject you're teaching. Have fun trying new items together! Many schools provide iPads or tablets for student use. Download some fun math games for your students to play. If you teach a college course, have your history students create entries for educational apps such as Clio. Try to energize your students by taking them out and about. Field trips are an excellent way to inspire and wow your class. Just make sure to tailor the trip to fit the needs of your students. Try a children's museum for young kids. For example, the Museum of Science and Industry in Chicago offers an entire wing of exhibits geared towards children. If you teach high school or college students, try a walking tour. The Freedom Trail in Boston is a great option if you teach in that area.
