In one sentence, describe what the following article is about: You likely have a number of experts in your area who can talk about environmental issues. Invite them to come talk to your class or even an after-school environmental club. For instance, you could invite someone who works for the local parks and recreation department or a person who works at the recycling center. Another good choice would be someone who works for a nature center or preserve or even the zoo. You can discuss things like turning off the lights when you leave a room, turning up the AC a few degrees warmer, doing laundry in cold water, and unplugging devices when they're not being used. You could also talk about making energy-efficient choices in the home, such as switching out incandescent bulbs for fluorescent bulbs or LEDs. Connecting kids with science centers helps them learn about ways they can conserve. Plus, most science museums will have special events for WED day. Videos are a great way to engage students in learning, and you can find a large number of professional videos for kids on conservation. For instance, PBS has a nature section at http://www.pbs.org/wnet/nature/classroom/.
Summary: Invite people to talk about nature and conservation. Talk about ways to conserve energy. Go on a field trip to a science or natural history museum. Watch a few professional videos.

In one sentence, describe what the following article is about: Dry nails are brittle nails. To reduce splitting and breaking, rub a moisturizing cream or olive oil into the cuticles daily. Petroleum jelly or a thick, greasy hand lotion that seals in moisture should do the trick as well. Biotin may not have much of an effect unless you have severely brittle nails, but it may be worth a try. A daily dose of 30 mcg is enough to avoid deficiency. Some people take a much larger daily dose of 2.5 mg to strengthen nails. You can also increase your biotin intake naturally by consuming more eggs, almonds, sweet potatoes, and other dietary sources of this B vitamin. Talk to a doctor first before you start taking any new supplements or make any major dietary changes. . Many beauty websites and magazines tout specific foods or supplements. There is little to no evidence that most of these work. In general, a balanced diet with plenty of vitamins and minerals from food should be enough to avoid nail problems. Some people may benefit from calcium, iron, zinc, or vitamin B supplements, but only if their diet is low in these substances. Talk to your doctor for more information. Don't believe myths about gelatin or garlic strengthening nails. These have no noticeable effect when eaten or used to soak the nails. Protein is necessary to grow fingernails, but very few people in developed nations are protein-deficient.
Summary: Moisturize the cuticles with oil. Consider biotin supplements. Eat a healthy diet

In one sentence, describe what the following article is about: The empty roll should be on a plastic spindle or roller. Remove both the empty roll and the roller holding it. Slide the spindle out of the grooves it is resting in, by lifting it upward and to the rear of the dispenser. Smaller tape dispensers may not have a spindle. You should see a plastic core (or roller) with the empty cardboard tape roll surrounding it; remove both of these from the dispenser. Slide the empty tape roll off its spindle, and discard it. If the empty roll is cardboard, it can probably go in with your paper recycling. Remove a new, full roll of tape from the box. Check the box to make sure you've got the correct size for your dispenser. Hold the full roll so that when you pull the tape, the strip of tape will unwind across the top of the roll. The sticky side of the tape will be facing down, toward the floor. (If you are holding it the wrong way, the tape will extend away from you, as it pulls from the underside of the roll; the sticky side of the tape strip will be facing upwards, toward the ceiling.) Slide new roll of tape onto the tape dispenser spindle from either direction; most rollers will fit into the dispenser either way. Hold the spindle so that the paper tab on the end of the roll is facing up and toward the front of the dispenser. Slide the spindle and the new full roll of tape back into dispenser. Settle it into its holding grooves so that it moves freely. Hold onto the paper tab at the end of the tape, and pull it towards the cutting edge at the end of the dispenser. Pull the tape over the sharp edge, and pull down on the tape to cut off the colored tab.
Summary:
Remove the empty roll. Remove the empty tape roll. Ready a new roll. Align the tape. Slide the tape roll onto the spindle. Align the spindle. Load the tape.
