Science Experiments - Kid's Preschool Science Activity

Science experiments for kids do not always have to be complicated experiments. Fact is that science is all around us in simple and complex forms, from our weather, to nature to simple chemical reactions from regular household or everyday items. Science activities and learning can be fun for adults and for children as well. Science allows children to learn by doing and by observing. Senses like touch, hearing, sight, smell and taste may all be part of learning about science, depending on the purpose of the science experiment itself.

*Always exercise 'CAUTION' and have proper Supervision with any new science experiments where uncertain reactions may occur.

What you will need for this science experiment:

2 large bowls or bins
2 large chunks of ice or snow
Coarse Salt or industrial salt for melting outdoor ice
Chart Paper
Marker

What to do for this science experiment:

Fill the two bins with the snow or ice. Ask the children who thinks the ice alone will melt more quickly, and how many children think the ice with the salt will melt more quickly. Document their answers on chart paper. Dump a handful or two of salt onto the ice in one of the bins and wait to see what happens. Document the end result and compare it with the children's answers.

How does salt make ice melt more quickly?

Answer: When the ice starts to dissolve it changes the temperature in the ice slightly, causing it to start melting faster than ice just sitting on its own. (Same answer if using snow instead of ice).
