One Easy Way To Test Batteries

You probably think this is a no brainer.

DUH people will swim faster in water, because syrup is thick. But the real answer is SUPER SURPRISING. 

Science put things to the test to this “simple” question. 

Sixteen volunteers took turns swimming in water and then a syrupy mixture.

Their times were thoroughly compared and, there was no difference between the speeds in the water versus the syrup. How can that be?

The explanation seems to lie in the fact that, while syrup does provide more resistance for the swimmers to overcome, it also helps them generate more forward momentum by pushing against the thicker liquid.

Materials: 1.jelly crystals 2.small cups 3.iron filings 4.calcium chloride 5.zip lock bag 6.water 7.adult Steps: 1.First, Fill one cup with 9 ounces of water 2. Next add a scoop of jelly crystals to the water and wait until the crystals are fully grown. ( The crystals are done growing when there is no more water in the cup) 3. Then add 4 tablespoons of the full-grown jelly crystals to a Ziploc bag 4. Next add 1 tablespoon of iron filings to the bag 5. Then, add a one and a half tablespoons of calcium chloride 6.next, mix everything in the bag by squishing the bag with your fingers 7.then, when everything is mixed, seal the bag 8.finally, squish and squeeze the bag to feel the heat coming out from it Lesson: When the water and Iron is contacted with air, rust is made with a byproduct of heat. Calcium chloride and water produces an exothermic reaction which starts the oxidation of the iron.

Materials: 1.granulated sugar 2.food coloring 3.stovetop safe container 4. Cream of tartar 5.candy thermometer 6.light corn syrup 7.water 8.adult 9.aluminum foil pan 10.measuring utensils Steps: 1. First, add one and three forts of sugar in the stove top safe container 2. next, add 1 cup of water 3.then, add half a cup of corn syrup 4.next, add 1/8 teaspoon of cream of tartar 5.then, combine all the ingredients 6. Next, slowly heat the heat the mixture at a low boil while stirring 7.then, keep the mixture add a low boil and please a candy thermometer in the container. 8.next, keep the mixture boiling until the temperature reaches 300 Fahrenheit 9.then, pour the mixture into the foil pan 10.next, add food coloring to the pan and spread the colors 11.finally, let the mixture cool until hardened. Lesson: This experiment is used in candy making. When you add corn syrup, it prevents the sugar from re-crystallizing. The cream of tartar separates the sugar crystals into glucose and fructose, which are simple sugars. The light that passes through the translucent sugar glass will take the colors from the food coloring you choose

Materials: 1. Brown sugar 2. 2 zipper-lock bags 3. Half and half 4. Adult supervision 5. Vanilla extract 6. Ice 7. Rock salt 8. Large empty container with lid 8. Measuring utensils Steps: 1. First, fill the large container half full with crushed ice. 2. Next, add 6 tablespoons of rock salt to the ice and seal the container and shake the ice and salt for 5 minutes. 3. Then, mix 1/2 a cup of half and half, 1/2 cup tablespoon brown sugar, and 1 teaspoon of vanilla extract in the zipper bag. 4. Next, tightly seal the bag and place it inside the other zipper bag. 5. Then, place the bag inside the container with the salt and ice. 6. Next, shake the container and the ice cream will be ready in 17 minutes. 7. Finally, remove the bags from the jar and rinse them with water and enjoy! Lesson: Salt causes ice to melt. When salt comes in contact with ice, the freezing point is lowered. Heat must be absorbed by the ice to melt, which means the heat that causes the melting comes from its surroundings. By lowering the temperature at which ice is frozen, you are able to create an environment where the cream could freeze at a freezing temperature to make ice cream.

Newton’s FLYING BEADS! Easy Kids Science Experiments 

Watch as Newton’s Beads fly out of a cup as a result of INERTIA!

According to Isaac Newton, an object at rest stays at rest and an object in motion (like the beads) stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
