In one sentence, describe what the following article is about: Also bring a hat and use it to keep your face out of the sun. Don’t forget to bring a coat or jacket to wear at night when the temperature plummets, especially if you are traveling to a desert. You probably won’t have room for several bulky coats or sweaters, so bring only one or two. Underneath, you can wear long sleeve shirts or thermals that you change each day. And don’t forget to pack warm socks!  Pack as lightly as you can. This includes packing lightweight clothes, if possible. Your baggage will be easier to carry and you will be able to fit more items in your suitcase. Choose simple clothing items (e.g. solid colors plus a couple of standout pieces) so that you can easily mix and match them. This way you will have to pack fewer clothes. Planning on hiking? Don’t leave without a pair of sturdy boots. For the beach, you’ll want a pair of flip-flops. If you’re planning on attending a formal event or going to an upscale dinner, make sure to bring dressier shoes with you. Besides clothes, you’ll want to take a variety of other items with you. Start out by making a list of essential items that you use every day – things like your toothbrush and toothpaste, computer and cell phone chargers, deodorant, and hairbrush. Go over this list several times to make sure you’re not forgetting anything. If your travel plans include flying, you won’t be able to bring things like certain snacks or large bottles of liquids with you. Luckily, travel-sized versions of necessities such as toothpaste, lotion, shampoo, or conditioner are easy to find in local stores such as Walgreens or CVS. If you’re traveling out of the country and plan to bring electronics with you, check to see what type of power adapter is used in your destination. Make sure to get your hands on the required adapter before you leave so you can plug everything in once you get there. Take these with you on your purse or carry-on luggage so that, if your bags are delayed or another such circumstance arises, you don't miss out on a dose. You may also want to bring a small amount of over-the-counter pain relievers and allergy medicine.
Summary: Pack several pairs of shorts and t-shirts if you're going somewhere hot. Dress in layers if you are going somewhere cold. Think about what kind of footwear you’ll need. Pack other essentials. Take a look at the TSA Guidelines. Consider what electronics you’ll need. Bring enough of any prescription medications you take to last the entire trip.

In one sentence, describe what the following article is about: Though caffeine can make you crash and be even more tired than you were to begin with, if you're reaching those late hours of the night and your eyes feel like sandbags, if may be time to have some emergency caffeine.  Start off with a cup of black tea. Its side-effects will be less intense than the effects of coffee. If you're already a big coffee drinker, have 2 or 3 cups. If you're really desperate, drink an energy drink like Mother, Monster or Red Bull. Make sure you do not consume a lot of these drinks, preferably 4 cans at the maximum! This will certainly give you a boost of energy for an hour or two, but the crash afterwards can be significant. It's better to have experience with energy drinks before chugging one to pull an all-nighter. When you're trying to stay up all night, you should eat just enough to maintain a healthy level of energy, but not so much that you feel bogged down and sluggish. If you've already eaten your three healthy meals, then you shouldn't be too hungry while you're staying up all night, but there are still a few foods that can help you stay awake if you're having a craving.  Eat a hard-boiled egg or quickly make an egg sunny-side up if you're at home. Eat a handful of almonds, cashews, or pecans. Eat a crispy apple, celery, or carrot sticks. Just crunching into these foods will wake up your mouth and will make you more alert. Bananas are great for all-nighters because they keep you awake for longer than usual and give you a great source of Vitamin B1 and potassium. Have a piece of toast with a little bit of peanut butter. If you're craving a fourth meal, try to have a healthy carbohydrate like brown rice and protein like turkey. If you can't avoid ordering out, try picking foods that aren't too greasy or fatty. Staying hydrated can help you stay awake significantly. Drink a glass of ice water to shock your body awake, and drink water frequently to keep your body hydrated and to continue to feel refreshed. Drinking lots of water will make you have to go to the bathroom often. This can also help keep you from dozing off.
Summary: Drink some caffeine in a pinch. Eat the right foods. Drink lots of water.

In one sentence, describe what the following article is about: These are the components of your robot's circuit. While you'll use two of the transistor's wires (or "leads") in the circuit, one of the leads must be left alone for later; you can use the needle nose pliers to bend this lead over. The photoresistor's two leads are usually an inch to an inch and a half in length, so use the wire cutters to snip all but about 3/4 of an inch off of the leads. This will make the photoresistor less cumbersome to mount later. Take the other exposed end of the wire that you soldered to the battery holder, then solder it to one of the photoresistor's leads. Solder each of the photoresistor's leads to each of the unbent transistor leads. You'll solder one end of the resistor to the photoresistor lead that isn't connected to the battery compartment's wire. At this point, your photoresistor should have one lead that's connected to a transistor lead and the battery compartment wire, and one lead which is connected to a transistor lead and the resistor lead.
Summary:
Lay out the resistor, photoresistor, and transistor. Bend away one of the transistor's three leads. Trim the photoresistor's leads. Connect the battery compartment to the photoresistor. Connect the photoresistor to the transistor. Connect the 4.7k resistor to the photoresistor.
