Problem: Article: Using a calculator program is the best way to get used to the keys on the numeric pad. You can use the numeric pad keys to perform calculations in the calculator program. When the numeric pad is not activated, the 8, 4, 6, and 2 keys will act as arrow keys. Press NumLock to enable the keypad. Some laptop keyboards do not have a separate numeric pad. They often need to be activated using the Fn key, which changes keyboard functions. Like the main part of the keyboard, the numeric pad has a Home position. On the 5 key, you will feel a raised bump similar to the F and J keys. Place your right middle finger on the 5 key, and then place your right index finger on the 4 key. Place your right ring finger on the 6 key, and your thumb on the 0 key. Your pinky rests on the Enter key. Use your fingers to press the number keys. you will see the numbers appear in the calculator program. Use repetition to memorize the number placement and which fingers you use to press them. Around the edge of the numeric pad, you will see the basic arithmetic keys. These let you divide (/), multiply (*), subtract (-) and add (+). Use these keys to perform a variety of calculations.
Summary: Open the calculator program. Use NumLock to toggle the numeric pad. Find the Home position. Enter numbers. Perform calculations.

Problem: Article: In 1969, Swiss psychiatrist Elisabeth Kubler-Ross published a book called "Death and Dying" about her work with terminally ill patients. She developed a model for what she called the five stages of grief: denial, anger, bargaining, depression, and acceptance. Everyone grieves differently, and these stages do not necessarily unfold in a set orderbut the model may give you perspective on your own process. The first reaction to learning of the death of a loved one is to deny the reality of the situation. It is a normal reaction to rationalize overwhelming emotions; indeed, denial is a defense mechanism that dulls the immediate shock. This carries you through the first wave of pain and bewilderment. As the masking effects of denial begin to wear down, you may be flooded by the painful reality of the situation. If you aren't ready for this pain, you may subconsciously deflect it toward others: friends, family, strangers, or inanimate objects. Try to maintain perspective and recognize this deflection. You can't help what you feel, but you choose whether or not to let these feelings control you. Many people react to feelings of helplessness and vulnerability by attempting to regain control. In terminal patients, this often takes the form of desperate measures to cling to life. In mourning, this often manifests as rumination: If only I had been there for her... If only we had gotten to the hospital sooner... If only, if only, if only. When the desperate bargaining subsides, you may be unable to avoid the reality of the situation. You may worry about the cost of the burial or feel an acute sense of regret. You may feel empty, sad, alone; you may despair at ever moving on with your life. This is part of the healing process. Take your time. The final stage of grief unfolds as you begin to move on. This stage is characterized by withdrawal and calm. Accept that your loved one has moved on, and acknowledge that you, too, must move on. Embrace the present as the new reality, and come to terms with the permanence of what has happened. Acceptance does not happen overnight. It does not necessarily mean that you are happyonly that you have moved beyond the denial, the anger, the bargaining, and the depression. Just like a forest that has burned slowly heals, sprouts, and blooms again, your life will bloom again with new hope. Give it time.
Summary: Consider the five stages of grief. Identify the denial phase. Recognize the anger phase. Be aware of the bargaining phase. Ride out the depression phase. Accept the situation.

Problem: Article: There are many different ways for you to build an animal cell model out of common, inexpensive materials. Take some time to consider what supplies you already have around the house that might work. In general, some supplies you will require include: Modeling clay or play-doh in many different colors Styrofoam balls of varying sizes Several colors of paint Glue Toothpicks Scissors and/or a sharp knife Pipe cleaners Construction paper Small, round objects such as buttons, dry noodles, beads, pieces of cardboard or foamboard, glitter/confetti, or small pieces of plastic A large Styrofoam ball is probably the best option for you to use as your cell base. However, any other spherical object that is not hollow and that can be cut with a knife or scissors could work, such as a large ball of soft clay. If the ball is not yet colored, paint the outside of the ball any color you wish. You could also use your favorite color of play-doh or modeling clay to coat the outside of the ball in a solid color. Using a sharp knife, cut away one-quarter of the ball. Do this by marking the top of the ball with a pencil. Then cut through that top point until your knife has reached the very center of the ball. Remove the knife. Then turn the ball exactly 90 degrees and make another cut into the center of the ball. This should allow you to remove a perfect 90-degree chunk from the ball. This will allow you to represent the internal workings of the cell in the form of a cross-section. The internal parts of the ball should be painted a different color. This will represent your cytoplasm. You can paint the cytoplasm any color you wish, though a lighter color will allow your cell parts to show up more clearly. Be creative about what common household objects can represent different cell components. If you have trouble finding an object that resembles an organelle, you can create your own using play-doh or modeling clay. Attach these cell components to the cross-section of your cell using glue or toothpicks, depending on the texture of the material. Soft materials such as styrofoam or clay should be attached with toothpicks; hard, slick material such as plastic should be attached with glue. Always refer to your original diagram to make sure you are placing everything correctly. A few suggestions for objects you can use in your model include the following: For your nucleus: a small ball of play-doh or clay, a smaller styrofoam ball (cut in half), a ping-pong ball (cut in half), the plastic top of a large milk jug, or a plastic egg For your endoplasmic reticulum: string, twine, pipe cleaners, rubber cords, or bungee cord For your Golgi bodies: a small stack of cardboard circles glued together, a folded piece of ribbon Ribosomes: confetti, glitter, dry rice Lysosomes: buttons, small plastic circles, small paper or cardboard circles, small clay balls Mitochondria: dry macaroni noodles, oval-shaped buttons or toggles, almond-shaped beads, dry beans Vacuoles: glass marbles, hollow rubber balls cut in half, bottle caps, small cut-up pieces of a plastic bag For each cell component (nucleus, lysosome, mitochondria, etc.), create a toothpick flag by gluing a small, triangular piece of construction paper to a toothpick. Label each cell component clearly and correctly. Then insert these toothpick flags into the open cross-section of your cell model. Now your teachers and classmates will be able to distinguish the parts of your cell model!
Summary:
Purchase your supplies. Use a solid, spherical object as the base of the cell. Cut away 1/4 of the ball. Paint the newly-exposed cross-section of the ball a different color. Attach your cell components with glue or toothpicks according to your diagram. Label your cell components with toothpick flags.
