Hi Mandi,
Our children are 8 years and almost 5 years old.
My 8 year old attends the homeschool science days (grades 1-8) and really enjoys them.
Currently, they only offer a few classes per year but he also attends the many 'special' days that they offer.
He is extremely interested in science, electronics, robotics, engineering, etc.
The next class is coming up in April and you can check out the description on the website.
My 5 year old attends the 'little lab' series and loves it as well.
Best,
Julie
