Fill the film canister one-half full with water. Get ready to time the reaction of Alka-Seltzer and water. Place one of the pieces of Alka-Seltzer tablet in the film canister. Time the reaction and write down the time. How long does the chemical reaction last? In other words, how long does the liquid keep bubbling? Why do you think the liquid stops bubbling? Empty the liquid in the film canister into the trash can.
Repeat the experiment, but this time place the lid on the container right after you drop in the piece of Alka-Seltzer. Remember to start timing the reaction as soon as you drop the tablet into the water. Write down your observations. A few dozen eggs that are in egg cartons Select large-sized eggs Large plastic trash bags Bucket of soap and water Some disinfectant Barefoot friends Note: Spread the plastic trash bag or bags out on the floor and arrange the egg cartons into two rows.
Inspect all of the eggs to make sure there are no breaks or fractures in any of the eggshells. Make any replacements that might be necessary.
Just make sure that all of the eggs are oriented round side up. By doing this, your foot will have a more level surface on which to stand. Remove your shoes and socks. Find a friend to assist you as you step up onto the first carton of eggs. The key is to make your foot as flat as possible in order to distribute your weight evenly across the tops of the eggs.
If the ball of your foot is large, you might try positioning it between two rows of eggs instead of resting it on the top of an egg. When your foot is properly positioned, slowly shift all of your weight onto the egg-leg as you position your other foot on top of the second carton of eggs. Nails for Breakfast Her morning bowl of cereal is a chance to learn about magnets and health. Open the box of cereal and pour a small pile of flakes on the plate.
Crush them into tiny pieces with your fingers. Spread out the pile so it forms a single layer of crumbs on the plate. If you get a piece to move without touching it, that piece may contain some metallic iron. Lift it up and look underneath to see if anything is clinging to the magnet. Several little pieces may be stuck there. Is it the magnet being attracted to static electricity or just sticky cereal? It could be the iron. Throw away the small pile of cereal and clean off the magnet.
Pour water into the plate and float a few flakes on the surface. Hold the magnet close to but not touching a flake, and see if the flake moves toward the magnet.
The movement may be very slight, so be patient. With practice, you can pull the flakes across the water, spin them, and even link them together in a chain. Could it be metallic iron? Fill the bag one-half full with warm water. Carefully seal the bag, leaving an air pocket inside. Mix the cereal and the water by squeezing and smooshing the bag until the contents become a brown, soupy mixture.
Allow the mixture to sit for at least 20 minutes. Make sure the bag is tightly sealed and position it on a flat side in the palm of your hand. Place the super-strong magnet on top of the bag. Put your other hand on top of the magnet and flip the whole thing over so the magnet is underneath the bag. Slowly slosh the contents of the bag in a circular motion for 15 or 20 seconds. The idea is to attract any free moving bits of metallic iron in the cereal to the magnet. Use both hands again and flip the bag and magnet over so the magnet is on top.
Gently squeeze the bag to lift the magnet a little above the cereal soup. You should be able to see tiny black specks on the inside of the bag around the edges of the magnet. Keep one end of the magnet touching the bag and move it in little circles. As you do, the iron will gather into a bigger clump and be much easier to see. Few people have ever noticed iron in their food, so you can really impress your friends with this one.
Place a new, unused diaper on the piece of newspaper. Carefully cut through the inside lining and remove all the cotton-like material.
Put all the stuffing material into a clean, zipper-lock bag. Order a custom-written paper of high quality Plagiarism-Free guarantee. Professional Writers only Free Quote or Order now.
