Many Homeschoolers use a curriculum that they buy from a company and that seems to work great for them but for us it was a total bust and waste of money. Now I homeschool basically for free and rarely ever buy anything to use in our daily lessons.
Science is a subject that Hyper Heathen actually doesn't mind doing. For a few years our Science was covered with "Homeschool Science Classes" at a local museum but it was quite pricey especially after we moved to the suburbs. HH enjoyed the classes though and made some really great friends that he is still close to today.
Science covers all forms and categories of science from Earth Science to Astronomy, Biology to Geology, Chemistry to Physics, and everything in between! Some of the things we might do are:
* Having him watch shows like Beakman's World and Bill Nye The Science Guy to introduce topics to HH that we can further study. We use these only as a jumping off point since he is older.
* Using our microscope to study everything from dead skin to plants.
* Chapter reading from books I get from the library. Recently he finished reading "DK Time and Space"
* Watching documentaries on our planet, insects, animals, space, how machines work, chemistry, biology, etc.
* Worksheets from workbooks I bought at Costco and teaching stores (they cover lots of great subjects and are a great launching point for further learning) as well as ones I print for free from the internet.
* Nature Walks where we explore the local plant and insect life documenting as we go.
* Field trips to Museums and places where we can learn how something is built or works. You'd be surprised how many local businesses are willing to teach kids about what they make!
And some other ways that just come naturally as we go about our day.
Hopefully I've helped you with some ideas but if you can think of anything you'd like to see involving homeschooling a child with ADHD please leave me a comment with your suggestion and I will do my best.
