Below is a list of science topics that you might want to investigate.

Check out books from the children’s section of the library to get you started, then dig deeper as interest dictates. This is also a good way to give your child all those "brain hooks" that will serve him or her well when the time comes to study more seriously.

It would also be a good idea to keep some general reference books in your home library.

Here are some of our favorites: 

• A good set of encyclopedias (i.e., World Book)
  
  
• The Usborne Illustrated Dictionary of Science (middle/high school, but usable for younger children with adult guidance) Note: Some people find Usborne a bit too “busy” (colorful and packed) for their tastes, but the books are useful enough to put some effort into getting past that. Consider teaching children how to first take in the page as a piece of art – just let it overwhelm you, then focus in on the one aspect you wish to explore. It’s the same strategy we sometimes have to use in every day life situations that threaten to overwhelm us.
  
  
• Science Yellow Pages for Students and Teachers by Kids’ Stuff  (excellent and easy reference tool, under 75 pages but packed full and well-organized, available on Amazon) Note: This book is packed with info (lists, charts, diagrams, suggested questions for students to explore, glossaries, and much more) and is very simply laid out – not overwhelming at all. Sections include: general, physical, earth and life sciences.
  
  
• Field Guides. In our opinion you can't have too many field guides. You can get simple ones for younger children, but the grown-up versions are more worth the money and just as interesting to little ones. The best way to find guides you'll like is to go to a big book store and spend some time looking. Most libraries have a selection of field guides, which you can borrow or use to research ones you'd like to own. There are guides for everything from animals in general to birds to reptiles to trees to poisonous plants to medicinal plants to seashells to stars and planets, to you-name-it. Besides looking in the field guide section, check out specific topics. You probably won't find a field guide to horses, but you'll find to equivalent in the horse section.

Topics

• Human beings (anatomy, different systems and how they work, genetics etc.)
• Animals/Zoology (categories, anatomy, habits and habitats, etc.)
• Marine Biology (creatures of the sea)
• Biochemistry (the chemistry of life)
• Plants/Botany (types, uses, photosynthesis, etc.)
• Ecology (relationships between organisms and their environment)
• Paleontology (fossils and ancient life forms)
• Medicine
• Nutrition 

• Earth/Geology (rocks, water, wind, cycles (water, rock, oxygen, nitrogen), minerals, biomes, earthquakes, volcanoes, etc.)
• Weather/Climate/Meteorology
• Space/Astronomy
• Acoustics/Sound
• Optics/Light/Vision
• Chemistry (chemical make-up of things)
• Physics/Matter/Energy
• Electronics
• Mechanics

The list could go on for a long time, but this will get you started. Progress according to your child’s interests or do something organized (one week or month per topic)
