Problem: Article: Instead of filling in lots of small veins or details, take a large black pen or marker and go around the outline of each heart segment. This will make them stand out so they're easier to color in if you like. For an even more basic heart drawing, just draw the boundaries of the heart, but don't draw the main arteries or large veins. To draw in the heart as though it were a coloring page, use bright crayons, markers, or colored pencils. Then, fill in each part of the heart with a different color so they stand out. Use a fine black ink pen to show depth and fill in spaces between parts of the heart. Then, use charcoal or a pencil to shade or cross-hatch so each part looks three dimensional. To determine which parts of the heart to make the darkest, decide where you'd like to make shadows and light appear. For example, shade the lower half of the heart and make the upper segments lighter. If you'd like to make a colorful heart instead of leaving it black and white, you could use burgundy or dark rusty red to fill in the darkest spaces of the heart. If you're trying to identify parts of the heart for a class you're taking, it's good practice to draw the heart yourself and label each segment. You can refer to your textbook in order to label the: Aorta Superior vena cava Inferior vena cava Right and left atria Right and left ventricles Pulmonary veins and arteries If you're learning about how blood circulates through the body and the heart, draw tiny arrows within the heart's segments. Consult your anatomy book to draw arrows that show where the blood enters the heart, the valves it moves through, and the direction it exits the heart. Consider making the arrows for deoxygenated blood blue and oxygenated blood red. At its simplest, the blood flows into the right atrium, through the right ventricle, and through the pulmonary valve to the lungs. The left atrium gets blood from the lungs and it flows to the left ventricle before going through the aorta to the rest of the body.
Summary: Simplify the details for a cartoon-style human heart. Use markers or crayons if you'd like to make the heart colorful. Shade in veins and details to make a hyper-realistic heart. Label the parts of the heart if you'd to reference it for anatomy. Make small arrows that show the flow of blood for another study aid.

Problem: Article: Cut a piece of yarn or something similar and drag it around the floor or bed, and watch your cat go crazy after it! This is almost guaranteed a success, since all cats love strings! Ever heard of Maru? Cats are in love with boxes and will most likely jump in them, because they seem so fun! Specially if there's a treat waiting in the box. This might leave some scratches! Have your hand under a blanket, and wiggle your fingers to make the blanket move. Your cat won't know it's you, and he/she will be acting mad, trying to catch the little "mouse" under the blanket!
Summary: Cats love strings! Cats love boxes! The hand under the blanket.

Problem: Article: You can build a box feeder out of any size or type of wood, depending on your needs and specifications. Ideally, you would purchase a cedar fence slat which measures 5" x 1/2" x 4 ft. Cut the wood you purchased into four pieces of various sizes to make the base, the back, the lid, and the sides. If you are utilizing a 5" x 1/2" x 4ft piece of wood, you should cut the pieces to the following specifications: Back= 10 x 5 inches Base = 12 x 5 inches Sides = 5 x 5 inches (2 pieces) Lid = 5 1/2 x 5 inches Drill the first hole about 1" from the top of back piece in the center of the wood and drill a second hole roughly 7" below the first one. The two side pieces need a 1/4" deep saw kerf made about 3/16" from front edge. This will allow the plexiglass front cover slide up and down. One of your side pieces needs a hole drilled thru at the saw kerf, so that it is just large enough to allow the nail to be put in by hand. This will keep the plexiglass from being lifted up by the squirrels. First, fasten the bottom piece to the back piece using 3 flathead screws. Then, fasten each of the side pieces to the bottom piece with 2 flathead screws and to the back piece with 2 flathead screws. Put the lid in place and screw a hinge to lid and the back piece. Make sure to use the screws that came with the hinge piece to ensure all the components fit together properly. Remove the plexiglass front cover and fasten the feeder to a tree or a post with the 2" flathead screws. Once you have fastened the feeder to a tree or post, select a food type and fill the feeder. Then, simply wait for the squirrels to come along and enjoy. Squirrels eat a wide variety of nuts, seeds and plants. While peanuts and corn, due to their wide availability, have become popular choices in stocking squirrel feeders, they actually provide very little nutritional value to the squirrel. Hickory nuts, butternuts, walnuts, sunflower seeds and pumpkin seeds are all healthy substitutes that the squirrels will enjoy.
Summary: Acquire an appropriate piece of wood. Cut the wood into five measured pieces. Drill pilot holes for mounting screws. Assemble your cut pieces of wood. Position the lid. Mount the feeder. Stock with food.

Problem: Article: You'll find these screws on the bottom portion of each track. They're used to secure the 2 halves of the track, the top of which doubles as a catch tab to hold the drawer in place. If the drawer you're attempting to remove has metal tracks but no screws at the end, they may be metal glide drawers with levers. See if you can find a pair of track levers to press that will then let you pull the drawer free. Turn the screws to the left (counterclockwise) to loosen them, then pull them free from the holes in the track hardware. Set both screws aside somewhere you won't lose them. Most drawers with stabilizer screws use 2in (5.1cm) #8 cabinet screws, which need to be removed with a Phillips screwdriver. Pull up on both tabs simultaneously. As you do, the top half of the track will come away from the bottom half, permitting the drawer to open past the stopping mechanism. There should be enough of a lip on the catch tabs for you to easily grip them between your thumb and forefinger. Without letting go of the catch tabs, guide the drawer off of its tracks. Hold it as straight as possible and move it in alignment with the tracks to prevent it from sticking. Once it's clear, set it down carefully and move onto the next drawer. If you're going to be removing multiple drawers, check the lip on the righthand side interior of each drawer for a small number decal. These indicate which drawer goes where, which will make it much easier to return them all to their proper place. To reinstall a drawer with stabilizer screws, simply work in reverse: align the door with the track, lower the catch tab over the track's bottom half, then thread and tighten the screws.
Summary:
Slide the drawer out and locate the stabilizer screws at the end of the tracks. Use an appropriate screwdriver to remove the stabilizer screws. Lift up on the catch tabs to separate the 2 halves of the track. Pull the drawer out the rest of the way.
