Grabbers

Grabbers are a way to get a classes attention and get them excited about science! Here is a list of grabbers that could be used in a classroom.

 Pop Rocks and Soda: First, pour a bag of pop rocks into an empty balloon. Then, attach the balloon to an open bottle of soda (12 oz. or 16 oz.). Make sure the pop socks do not fall in just yet. Then lift up the balloon and allow the pop rocks to gradually fall in. The balloon will then expand slightly. This works because the pop rocks are made up of pressurized carbon dioxide. Along with eh carbon dioxide found in the soda, this causes the balloon to inflate.

I did this grabber and here is what mine looked like:

 Elephant Toothpaste: This experiment requires yeast, water, empty plastic bottle, 6% hydrogen peroxide, food coloring, and dish soap. Mix the water and the yeast in a separate container first. Mix the 6% hydrogen peroxide, food coloring, and dish soap in the bottle. Then, pour the yeast mixture into the plastic bottle. This will make a foamy, toothpaste like mixture/explosion. These mixtures create a chemical reaction summarized by the formula 2 H2O à 2 H2O + O2 (Tip: you may want to use a metal sheet to catch the mixture under the plastic bottle)

 Mini Volcanoes: On a tray, place a large sum of baking soda. Mix vinegar and a few drops of food coloring in a cup. Using an eyedropper, squeeze the mixture onto the baking sodas. Mini volcanoes will begin to erupt.

 Magnetic Money: All you nee is a dollar bill and a super strong neodymium Magnet. Dollar bills are printed with magnetic ink as way to reduce counterfeiting. “Neodymium magnets (Nd-Fe-B) are composed of neodymium, iron, boron, and a few transition metals making them some of the strongest magnets in the world” this is strong enough to attract the small amount of magntic ink in the dollar bill.

 Floating Egg: What you need is two drinking glasses with water, two raw eggs, and four table spoons of salt. Only add salt to one of the glasses and watch as the egg will float in only that glass.

Mystery Tube: Mystery Tubes for exploring the Nature of Science can be made of mailer tubes or PVC pipe using rope. Less sturdy but easily made mystery tubes can be made with paper towel rolls and yarn knotted at the ends. The ends of the tube are sealed with non-transparent tape. No peeking inside allowed.
