Most likely you already have it, if not its a free download here This ebook contains three simple projects suitable for first to third grade students. You will most likely have everything at home to do these. This ebook has three projects which may be most appropriate for students in grade 4 or above. Younger students can certainly do these very easily but may not have been exposed to these science concepts yet.
All experiments may be done with items found in the home or any grocery store. This ebook contains a single project that can probably be completed in one week or less. The only item you may have to purchase here is a small pack of garden seeds. This project would be appropriate for most any age student but those you have studied biology related to plants would find it more interesting I think.
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. Scoop up any of the polymer that may have spilled onto the paper and pour it into the bag with the stuffing.
Blow a little air into the bag to make it puff up like a pillow, then seal the bag. Shake the bag for a few minutes to remove the powdery polymer from the stuffing.
Notice how much or how little powder falls to the bottom of the bag. Carefully remove the stuffing from the bag and check out the dry polymer you just extracted from the diaper. Pour the polymer into a plastic cup and fill the cup with water. Mix it with your finger until the mixture begins to thicken. Observe the gel that the polymer and water create. Turn the cup upside-down and see how it has solidified. Take it out and play with it. Put the pieces of gel back into the cup and smoosh them down with your fingers.
Add a teaspoon of salt, stir it with a spoon and watch what happens. Hold the diaper over a large pan or sink and continue to add water, a little at a time, until it will hold no more.
Keep track of how much water the diaper can absorb before it begins to leak. CO 2 Sandwich Get your little scientist into safety googles and learn about carbon dioxide together in two fun ways.
Safety glasses Measuring cup and spoons Vinegar Baking soda Reclosable bags quart-size zipper-lock bags and snack size zipper-lock bags Toilet paper Instructions - Plastic Bag Variation: Start by putting on your safety glasses. Fill three quart-size zipper-lock bags with approximately 1 tablespoon of baking soda.
Fill three snack-size zipper-lock bags with varying amounts of vinegar. Seal the vinegar bags and place them in the bags with the baking soda. When you seal the outside bags, make sure to remove as much of the air as possible.
Punch the vinegar bags inside the baking soda bags to break them open and then shake the baking soda bags to make sure the substances mix. Make observations about how large each bag gets and how long it takes before you hear the giant POP! Instructions - Toilet Paper Variation: Tear off a square of toilet paper. Place 1 tablespoon of baking soda in the middle of the toilet paper square.
Twist or fold the toilet paper around the pile of baking soda making a small packet. Zip the bag closed, but not all the way. You want a small opening just large enough to sneak in the wrapped up baking soda. Move the experiment to the sink, or better yet, outside. Drop the baking soda bundle into the bag and quickly seal the bag closed. Watch closely as the bag begins to puff up until the sandwich bag pops.
