Next, fill the first glass with a generous squirt of red food coloring, the third with yellow, and the fifth with blue. Mix it up with a plastic spoon. Leave the other glasses empty.

You have found the first in a four-part series on science experiments that kids can safely get involved with at home – while having fun! We hope these exciting chemical reactions will encourage children to learn about chemistry, and discover Refraction is the bending of light and it happens when light travels from one medium to another, like from air to water, or water to air. In this experiment, the light traveling from the paper through the air, then through the glass and into the water, and finally out of the glass and into the air one more before ever reaching our eyes.The explosive decomposition of energetic compounds can be triggered by heat, mechanical stress, light, catalysts (e.g., metals), or sparks. The sensitivity to each factor varies with the compound. Often, the stability of a compound decreases with increasing concentration, and the pure or dry compound is the most sensitive to decomposition. Scale of the experiment

Does your kid want to make something go BOOM? Fair enough, it doesn’t get much more exciting than an exploding science experiment which is why we have put together this fun list of 7 kids exploding experiments. From volcanos to soda geysers and unicorn toothpaste there are lots of exploding fun to be had here. Describe the effect of changes in temperature, concentration, pressure, and surface area on rate of reaction. Try it again, adding something that will float in the water. Repeat the steps, and see what happens! Cover the top of the straw with your thumb before lifting it out of the water so that the water does not fall out of the straw. Next,thread the other end of the pieces of yarn through the hole in the plastic bag and tie a knot.Instruct students to squeeze as much air as possible out of the bag without tipping over the film canister. Then seal the bag as tightly as possible. The demonstration can be set in context with stories about the explosion risks of powders such as sawdust from sanders, custard powder and flour in mills and coal dust explosions in mines. The latter can be contrasted with the difficulty often encountered in igniting large lumps of coal when lighting a fire. This apparatus can be improvised in a number of ways, but it is important that the resulting apparatus can blow a cloud of cornflour into the candle flame when the pipette filler is squeezed. An alternative arrangement is to place a small crucible inside the can, to contain the cornflour, and replace the funnel with a glass tube bent at right-angles, so that it’s tip is directed downwards into the crucible. Some prior experimentation and adjustment may be needed to ensure the demonstration works well. Let your child mold a volcano out of playdough around a small cup or container on a plate. Pour some vinegar through the top of the playdough volcano into the cup along with your child’s food coloring of choice. Pour a tablespoon of baking soda into the volcano. When your child is ready, let him or her pour the colored vinegar into the volcano with the baking soda. The vinegar reacts with the baking soda to produce carbon dioxide and since out the top is the only place for it to go, that’s where all the action happens! Elephant Toothpaste Kids of all ages will love these cool science experiments that you can do together on the weekend or after school.

Each tiny bubble in the foal is filled with oxygen. The yeast was a catalyst (it helper) to remove the oxygen from the hydrogen peroxide. Because it happened so fast, it created lots of bubbles. Philip Schofield and Holly Willoughby conducted a series of science experiments with the Institute of Making’s Zoe Laughlin on one of last week’s episodes of This Morning. STEM Skills At ReAgent, we believe that STEM (science, technology, engineering and maths) First, form snowballs by adding water to the baking soda. You’ll need about a 1/3 cup per snowball. First, pour the milk in a small baking dish until the bottom is covered. Next, fill the milk with drops of food coloring. Glitter is optional!Then, add 1 tablespoon of liquid dish soap and swish the bottle around the mix the ingredients together. Physical reaction or change: a change in which the physical properties (state, size, shape) of a substance alters, but the chemical make up remains the same. Predict and explain the effects of changes in the size of pieces of a reacting solid in terms of surface area to volume ratio. First, place the steel wool in a beaker. Then, pour vinegar onto the steel wool and let it soak for about a minute. First, set the paper cups on the grounds, spaced evenly. Next, place the cardboard on top of them. Then, try to stand on it and see what happens. Can you make another level?
