Tornado
Tornado
Replicating a tornado is a great way to understand the power of nature and how science plays a role in all forms of weather. Your child will begin to build an understanding of funnels, and how varying air temperatures can merge to create this devastating and fascinating weather formation. Your budding meteorologist will be captivated with his version of one of nature's most powerful weather systems.
ChildinScienceClassatSchool
Acid Rain
Researching acid rain will help your child understand how it can contaminate water supplies and pollute the environment. By creating his own acid rain laboratory, he'll also learn how to test the acidity of a liquid and how that can affect plant and animal life. This chemistry experiment is a great way for your child to become more environmentally conscious by investigating how his actions can affect his surroundings.
Lemons
Invisible Ink
Who knew lemons, milk, and vinegar could be used to write secret messages? Your child will discover the wonders of chemistry and acidic properties by creating invisible ink, and will love sending his friends covert messages on seemingly blank paper. This project is sure to be a hit at any science fair!
