Edible Home School Science Experiment – Homemade ice


It’s hot today, and you would like to take the kids out for a picnic. How would that change homeschool science experiment into the ice making session? Amaze your kids by showing them that with their help, you can make ice cream for them, and that of the moved them.

You have to make various recipes the night before or the hour before you set off for a picnic. Boil the mixture of one cup of milk with half a cup of sugar and a pinch of salt in boiling water bath. Add three beaten egg yolk mixture and stir until you get a thick creamy mixture coats a spoon. Cool it and add the vanilla essence and two cups of heavy cream and stir. Pour the mixture into 3 to 4 small zip-lock bags, each enough to make one dose. It is desirable to ensure this bag with another zip-lock bag. Now put the zip-lock bags with the mixture in an ice chest full of ice. You can now put the ice chest in the car as you travel to your favorite picnic spot phone. It is very important that the ice did not melt on the way home for a school science experiment to succeed.

At the picnic table you can put in any zip-lock bag in a large zip-lock bag that is half filled with ice. Sprinkle a little salt over the ice and seal big bag. Do this with all the small bags containing ice mixture. Add a little water on the ice will help enhance the process. Have as many such bags as many kids there are. Deliver one such bag for each kid and ask the kids to penetrate and shake bags. Maybe they can throw them up and catch them. The more they trample and shake the bags faster mixture will turn into ice. Let them have fun with bags for ten minutes. You can afford another five minutes to shake, shake and shake!

Then ask each kid to ice their package to you to investigate. Open each bag, and voila! Ice cream is ready! Once, let them enjoy their frozen treats! Is not this nice home school science activity? How was the liquid mixture turn into ice? And it, too, faster than it would take in the refrigerator? The very first thing to remember is that you have divided the mixture into small bags and not in one container as you would do in a refrigerator. Without salt, when the ice melts (at 0 degrees Celsius or 32 degrees Fahrenheit), it turns out the water by absorbing some heat from the atmosphere. At the same time the water gives out heat and refreezes in ice. This is called a state of equilibrium. The mixture requires a temperature less than 0 degree Celsius in order to make ice.

salt breaks this balance by changing the make-up of ice and water. Now the ice melts, the water does not freeze the product in the ice where it now has a temperature of less than 0 degrees Celsius to freeze the product. The ice now receives no heat to melt, and it draws heat from the mixture, making the ice cream mixture even colder.

Furthermore, salt (sodium chloride) is divided into the water in the charged particles of sodium and chlorine. The whole mixture of ice, water and salt will now be a special material that freezes at a temperature of -21.1 degrees Celsius or -6 degrees Fahrenheit. Therefore, the liquid ice cream mix frozen dough. To get more great science experiments and activities visit the free “Home School Parent’s Guide to teach science ‘link below.
