Problem: Article: You could use a reflective tabletop, a mirror, or other shiny, flat surface. Make sure the glare is noticeable even from about 2 to 3 feet (60 to 90cm) away. If you need to produce glare, you can turn on overhead lights or shine a flashlight on a reflective surface. You should be able to view the surface through one of the lenses at a time. Depending on the size of the lenses in your sunglasses, you might need to move them a little closer to your face. Your sunglasses should be on an angle at this point, with one of the lenses raised slightly higher than the other. Since sunglasses are polarized in a specific direction, rotating the sunglasses can make the polarization more effective. Depending on how the glare is hitting the surface, you might have to slightly adjust the angle of the glasses to see a noticeable difference. If the sunglasses are polarized, you will notice the glare disappears. When you look through one of the lenses, it should be very dark and you should see little to no glare, but it will still look like the light is shining on the surface. Move the sunglasses to compare your regular eyesight to what you see through the sunglasses a few times if you're unsure of the effectiveness of the polarization.
Summary: Find a reflective surface that produces glare when light is shining on it. Hold your sunglasses about 6 to 8 inches (15 to 20cm) in front of your eyes. Rotate the sunglasses upwards to a 60 degree angle. Look through the lens and check the level of glare.

INPUT ARTICLE: Article: This is dependent on the size of your grout's joint (the space between the tiles where the grout lies). There are two types of grout for regrouting tile: sanded and unsanded. If your grout joints are larger than 1/8 inch (.3175 cm) use sanded grout to fill in the space; if your joints are going to be less than 1/8 inch (.3175 cm) use non sanded grout to fill in your joints as it is more compact.

SUMMARY: Decide what type of grout you will be using.

In one sentence, describe what the following article is about: These exams are definitely not a walk in the park. The IB is hard for most people (even geniuses like us) so prepare for it! And when not if, when you pass your exams, smile and be thankful that it's over. Help the first year students. Work through as many past I.B exams as you can possibly handle! The questions in your textbook or those which you are completing in class may be drastically easier than the actual exam.

It should turn blue. As soon as it does, it's on and ready to sync. It's the panel on the front next to the eject button. You'll see a red button to the left of the SD slot. If there aren't any batteries in place (or the batteries are dead), place new ones in now. Use the tip of a pen or paper clip if need be. You do not need to hold the button down; it will activate after a quick push. If the LED lights on the Wii remote have stopped blinking, just push the SYNC button one more time. When the player LED blinking stops, the process is complete. You'll see an LED illuminated on your remote, indicating that remote's player number. This procedure must be repeated for each remote you'd like synced up.

In one sentence, describe what the following article is about: Take two of your four wider boards and place them together along the long edge. You'll end up with a square 9-1/2" wide, 12-1/2" long. Do this try run to make sure the cuts are even so that the boards come together to form an even rectangle. Repeat with the other two boards. These wider planks will be used to create your ends. Building this crate requires that you to adhere the two boards to make the ends. You have several options, including: Biscuit joints. The remainder of the tutorial will be using biscuit joints. Dowels Wood glue. Know, however, that this will not make a very strong box. Mark where you're going to adhere the boxes together on both blanks. For this tutorial, you'll use biscuit joints, though you can use any method you're comfortable with. Make sure you have three wooden biscuits as well as a biscuit drill. Three biscuit joiners for each end should be more than enough. If you're in a pinch, two will do. Like up the drill with your pencil marks and make a clean, quick cut with the drill. Repeat for the other 5 marks. One solid line of glue along the entire edge should be fine. Make sure each biscuit is snug inside the hole. Simply slot the biscuits into the slots on the other piece. Let the wood glue dry and your ends are finished. Use a rubber mallet to hammer the ends gently, but firmly, together. For the cleanest results, use a set of clamps to hold the two boards together as the wood glue dries. Now that the ends of the crate are finished, you can decorate them or add handles. You have several options: Using a table drill with a wide 1-2" drill bit, "punch" holes into each end to make a handle. Simply drill 3-4 holes in a small line to cut a handle in the wood. Using a power drill and some small screws, install two metal handles, like those found on cabinets, into the ends. If adding these handles, wait until the end to install them, as you'll need to lay the box down flush to the ground to finish it.
Summary:
Dry fit two of the wider boards together along the long side. Determine how you're going to adhere the two boards. With the wood pressed together, use a pencil to mark three spots for dowels or biscuit joints. Use your biscuit joint drill to make notches at each mark. Apply wood glue to all three biscuit holes on one of the planks. Insert a biscuit into each hole and firmly push it into place. Add a little more glue to the top of each biscuit, then attach the two boards together. Optional -- add handles to the ends.
