For this experiment, the globe will represent a round earth, and the map will represent a flat earth. The lamp in the middle will be the sun. This experiment works best when it’s dark out or all the windows in the room are covered. You want the light coming from the lamp to be the only light in the room. Look at the globe and notice how half of it is lit up and half of it is dark. Then, notice how the map is completely illuminated. The globe does, right? After all, if the earth was flat like the map, then all of the earth would be lit up by the sun at the same time. That wouldn’t make sense, since we know that the whole world doesn’t experience day and night at the same time. With the globe, half of it is lit up while the other half is dark. That’s the same as what we observe here on earth — half of the world experiences day while the other half experiences night. Therefore, it makes sense that the earth is round!

Summary: Place a lamp in between a globe and a world map. Turn off all the lights in the room except for the lamp. Observe how the light shines on the globe and the map differently. Ask yourself whether the round globe or flat map seems more realistic.


Whenever working with open flames, it’s important to take precautions. Keep a fire extinguisher nearby when you’re grilling. If you’re using a propane grill, check for any leaks and ensure that any tubes and fittings are secure. Whatever kind of grill you have, there are a few essential tools you’ll need to get your grill started.  Tongs. You’ll need these to spread the coal around. Long matches or a grill lighter. If you don’t have long matches, you can light a piece of paper with a small match and use it to light the coals. Oven mitts. Remove all ash and grease from your grill, scrubbing with a grill brush to remove any burnt-on fats. Wipe down the cleaned grate with cooking oil.  If you’re working with a gas grill, heat it up before cleaning. Then use a grill brush to scrape off the loosened food and debris. Cooking with a dirty grill can impart unpleasant flavors to your food. If you don’t have a grill brush, any metal-bristled brush will work. Charcoal grills have vents on the bottom of the grill. These vents allow air to enter the grill and stoke the fire. Opening the vents will make it easier to light the charcoal. The vent will usually be a circular disk on the bottom of the grill that you can twist to open the air holes.

Summary: Practice fire safety. Gather your tools. Clean the grill. Open the vents if you’re using a charcoal grill.

This is probably the fastest way to get longer hair! Go to a beauty supply store and pick out extensions that match your hair's color and texture. Clip them in under the top layer of hair, close to your scalp, so they'll blend in well.  Get enough clip-ins to evenly place around your hair, so one side doesn't look thicker than another. You can get clip-ins made from plastic, real human hair, and other substances. Keep in mind that synthetic clip-ins won’t blend well with your natural hair and they will not last for very long. The more you want to spend, the more realistic they'll look. This is a more expensive, more permanent version of extensions. Extensions made from real human hair or faux hair are woven, sewn, or glued to your hair or scalp. This is a popular method for getting instantly long hair used by celebrities.  It's extremely important to make sure you go to a salon technician who knows what he or she is doing. Do not get extensions or a weave done by an amateur. It can lead to pain, irritation, and hair loss. Only try  putting in your own extensions if you're extremely confident in your abilities! Otherwise, you might lose some hair in the process. Want instantly longer hair? Why not try a wig? You can experiment with all kinds of hair colors and textures, and best of all, you can make your hair as long as you want. Go to a wig store and talk with the representative there to help you pick out one that looks good with your coloring and facial features. You can even have your wig cut and styled at a salon if you want.
Summary: Get clip-in extensions. Get a professional weave or extensions at a salon. Try a wig.
