Q: New growth on Wandering Jew plants often attracts tiny green insects called aphids. They're usually found near stems. One effective treatment is pinching off or pruning the affected stems and heavily misting the remaining plant with water. You can also use a hose or high-powered stream of water to blast them off of the leaves. Mist your plant often. When the humidity is low, your plant's leaves will turn brown, but periodic water misting will help the leaves stay vibrant. Keeping the leaves wet will also help with any aphid problems your plant may develop. Fill a spray bottle with water and just mist until the leaves are lightly moistened. Brown leaves can also be a sign that your plant is getting too much sunlight. In this case, make sure your plant is not directly in the sun by moving the pot or placing a filter, such as a curtain, in between the plant and the window. Try to use distilled or bottled water when misting the leaves for the best results. Leaves that lack their notable vibrancy and color are probably not getting enough sunlight. Gradually increase the amount of sun your plant receives so that you don't shock the plant. This might involve moving the pot closer to a window that receives more light or finding a sunnier spot in the yard for your plant. If the plant is fading in color, but the leaves are turning a faded yellow, the plant may be getting too much water and the roots are rotting. If this is happening, the plant is probably not putting on much new growth, if any. You'll need to cut out the portion of the plant that is rotting, make a cutting from a healthy part of the plant, and replant it.
A: Treat aphids. Refresh brown leaves. Restore faded leaves. Remove root rot.

Q: In scientific terminology, a fact is an observation that has been repeatedly observed and is accepted as practically functional and "correct." While facts can be scientifically refuted or may not be consistent across time and place, they are held as true until they have been proven wrong. As you explain this concept, focus especially on separating fact from law, since both describe natural phenomena, albeit in different ways. When explaining a scientific fact, start with a point of general observation. For example, begin your explanation by saying something like, "it is always bright outside at noon." This is a fact in that it describes a state of naturehowever, this statement may not be true in Antarctica or Greenland, where darkness lasts throughout the day in certain seasons. Explain how this will lead to a revision of the scientific fact: "within certain degrees of latitude, it is always bright outside at noon." Facts are often the initial building blocks of scientific inquiry; they can generate curiosity and the hypotheses that come from inquiry and experimentation. Facts are less formal than laws, and are not seen as an "official" definition of a phenomenon that occurs or of the reason that something happens. Facts are more localized and generalize less than laws. Explain that, if the Law of Evolution describes the way that species throughout the world evolve over time, a scientific fact related to evolution (and natural selection) could be: "giraffes with long necks can reach more leaves than giraffes with short necks." Many students and adults hold to misunderstandings of scientific vocabulary and misunderstand the relationship of theories, laws, and facts. For example, scientific theories do not develop into scientific laws. To explain the difference, focus on this distinction: laws describe phenomena, theories explain phenomena, and facts describe observations.
A: Define a scientific fact. Provide examples of scientific facts. Clarify the distinction between scientific laws and facts. Clear up any common misconceptions.

Q: It's the yellow icon with a white ghost. Videos can last up to 10 seconds. If you haven't turned on filters, tap Enable Filters to access the special effects. The snail plays your video in slow motion, while the rabbit speeds it up. The three backwards arrows plays your video in reverse. Some filters change the color or brightness of the screen. Other filters add effects such as your current speed, location, or time. Some filters, such as the snail and rabbit, cannot be combined. It's the white right-pointing arrow at the bottom right of the screen.
A: Open Snapchat. Tap and hold the large circle icon to take a video. Release your finger when your video is complete. Swipe right or left to add special effects. Hold one finger down and swipe another to combine filters. Tap the "Send" icon. Tap on a recipient. Tap the "Send" icon again.

Q: The polarity of batteries is what helps them supply current to a device. The plus sign, or +, indicates the positive terminal. On AA, AAA, C, and D batteries, the positive end should be slightly raised. The negative end of the battery should be flat, and it may or may not be marked with a minus, or -, symbol. There should be a plus and minus sign inside the battery compartment. This will tell you which direction the battery needs to go. The negative end may have a spring or a small metal lever. If the polarity isn't marked on your device, you may need to consult the manufacturer's instructions. It's very important to make sure that each battery is properly aligned inside the device. If your battery faces the wrong way, it could cause your device to malfunction, or it could even cause the batteries to leak dangerous corrosive chemicals. The plus sign on the battery should match the plus sign on the device. As you insert the negative end of the battery, you may press down a spring or a lever. By installing the negative end first, the battery will slide into the compartment more easily. You should then be able to easily snap the positive end into place. The positive end of the battery should snap into place with a gentle push. If you have multiple batteries side-by-side, they may alternate directions. This creates a series of current that amplifies the energy produced by the batteries. Make sure each battery faces the direction that's indicated in the battery compartment or the user manual. Some devices that use multiple batteries may continue to function if one battery is installed incorrectly, but you can damage the device or shorten the life of the batteries by doing so.
A:
Look for a plus symbol on your battery. Find the positive and negative symbols on your device. Align the symbols on the battery with those on your device. Slide the battery into place with the negative end first. Check the alignment of every battery.
