Science can be a tricky subject for some people to teach, but it doesn't have to be so difficult. There are so many resources available online to help those who may need some assistance in teaching science to their homeschoolers. At this age, the most exciting thing you can do is science experiments! Besides, what kid doesn't love a baking soda/vinegar volcano explosion?
If you are in need of some science guidance, turn to the web for some information. What does your student find interesting? Are you learning about animals during your regularly scheduled science lessons? A really fun project to work on with your homeschooled kids is to make a cast of an animal track! If you can't find an animal track, then make a cast of your own tracks in the dirt to discuss what can be learned about animal habitats by tracing animals steps and prints.
Regardless of the topic, there's a good chance you'll find the information that you need if you start looking. Don't let science intimidate you! Learn to embrace the challenge of teaching what can be a difficult subject and find some neat experiments and projects to work on with your children!
