INPUT ARTICLE: Article: Heme is the easiest type of iron to digest and it aids the body in absorbing non-heme iron. Cook lean cuts of meat for your child and use healthy cooking methods such as baking, grilling, or broiling. Avoid fatty meats. Good meat-sources of iron include lean cuts of beef, chicken, and turkey. Salmon and tuna are also good sources of iron. Though these are not as easily absorbed by the body, they contain iron and should be consumed for other reasons. Provide your child with plenty of beans and legumes, as well as fresh iron-rich vegetables and dried fruits. Cereals can be extremely iron-rich. Plant sources are an important part of a healthy diet and are easily added to any recipe.   Popular iron-rich beans include soybeans, lentils, kidney beans, black beans, pinto beans, and garbanzo beans. Vegetables that are high in non-heme iron include yellow peppers, broccoli, Brussels sprouts, artichokes, tomatoes and leafy green vegetables, such as kale and spinach. Most fruits are not high in iron; however, dried fruits, prunes, raisins, and figs are a good source of non-heme iron. Replace high-sugar cereals that have very little nutritional value with healthy, iron-fortified cereals. Check the labels on ready-to-eat cereals and choose one that provides a significant amount of your child's recommend daily iron allowance. Oatmeal and cream-of-wheat are also very high in non-heme iron. There are many iron-rich foods that don't come from plants or meat. Be sure to include these to create a balanced diet for your child. Examples of non-meat and plant iron-rich foods are eggs, hummus, molasses, tofu, and enriched grains. If you have a picky eater, getting her to consume enough vitamins and nutrients may be difficult. Find recipes for kid-friendly meals that pack a big health punch. Until your child is old enough to realize the value of nutritional foods, you may need to get creative.   Cut up vegetables in foods your child likes. Pizza and macaroni and cheese are easy foods to supplement with sources of iron. Finely chop vegetables so they are less recognizable. Make a dish that completely incorporates the nutritious food. It is easy to make fruits and vegetables disappear in dishes like soups and even brownies.

SUMMARY: Get heme iron from meats. Get non-heme iron from plant sources. Choose healthier breakfast cereals. Get iron from other sources. Hide nutrient-rich food in recipes.


INPUT ARTICLE: Article: , if needed. Unless you are starting with a brand-new, pre-sanded floor, it's important that you sand the floor three times, with three different levels of sandpaper, to remove imperfections and smooth the surface. Begin with 36-grit sandpaper, followed by 60-grit, and finish with 100-grit sandpaper. Pay special attention to the edges and corners of the room. Use a commercial-grade vacuum to remove all the dust and debris from the floor. Your household vacuum likely isn't strong enough to get the job done, so consider renting a commercial machine for this project. Be sure to vacuum the edges and corners of the room as well. Use mineral spirits to clean the surface of the floor and remove all remaining debris and dust. Apply the mineral spirits to a clean cloth and wipe down the entire floor, paying special attention to cracks, edges, and corners. Allow it to dry fully before coating the surface in polyurethane. You can find mineral spirits at hardware stores, home improvement stores, and superstores in your area. To prevent you from accidentally brushing polyurethane on your baseboards, you need to mask them. You can use newspaper in conjunction with masking tape, or use masking tape alone to cover your baseboards.

SUMMARY: Sand the floor Vacuum the floor thoroughly. Wipe down the surface with mineral spirits. Apply masking tape to protect your baseboards.


INPUT ARTICLE: Article: This experiment works best with a bottle that has relatively thin plastic. You need to be able to twist the bottle, so bottles made of thicker plastic will be difficult to use. You also want to use a standard size (16.9 oz or 500 mL) bottle or larger, not the miniature ones.  You want the bottle to be mostly empty: if you leave a small amount of water in the bottom of the bottle, you will see a cloud of water vapor form at the end.  Bottles with smaller lids also tend to work better. While this step isn’t entirely necessary, it can make it easier to twist the bottle for the experiment. Recycle the label when you’re done with the experiment. In order to build up the air pressure inside the bottle, you need to decrease the amount of space available by crushing the bottle. Start by squeezing the middle of the bottle and twist the bottom.  Starting the twist can be difficult. In some cases it can be easier if the bottle starts out slightly deflated. Remove the cap, squeeze the bottle a bit and replace the cap while keeping the bottle slightly squished. Make sure the cap is tightly screwed on to the top of the bottle before beginning this step. As you twist the bottle, you will notice it will become more difficult. Twist the bottle as many times as you can until you can’t twist it anymore. If you are not strong enough to do it, ask an adult for assistance. Keep the bottle pointed away from your face and others while you are twisting the bottle. While it is unlikely for the bottle to pop during this step, it is possible. Grasp the bottle tightly against your stomach with the cap facing away from you. Use the side of your thumb to quickly twist the cap off. Make sure you fully twist the cap off, or the cap won't pop out. If done successfully, the cap should fly across the room.  Another way to pop the cap off is to hold the bottle between your legs and then twist it with your hand. If the cap does not fly across the room, there wasn’t enough air pressure built up inside the bottle. Untwist the bottle, blow into it to refill with air, and try again. When the cap flies off you may notice that a cloud of white vapor is coming out of the bottle as well. This is water vapor that is formed when the cap gets released. As the pressure builds inside the bottle, the water molecules get squeezed together. When the cap goes off, the temperature inside the bottle cools causing the water molecules to condense into vapor. This is also how clouds form in the sky. At cooler temperatures, the water vapor forms around dust particles to condense.

SUMMARY:
Obtain an empty plastic bottle. Remove the label from the bottle. Squeeze the bottle in the middle and twist. Twist the bottle about 4 to 6 times. Untwist the cap with your thumb. Watch the water vapor.
