Where to Begin Sci. older ones Apologia

We have never really done this formally. They have read some and they are 12 and 14. I really want to give them a “love” for science. The 14yr.old is immature and could be like my 12yr.old. They are not ready for Apologia General Sci. What Living books that are astounding and MUSTS and Fullbright books do I need to cover what they should have in the areas of Plant life, Human Body, Earth Sci. etc.?I want to do this this year or two before going onto Apologia General etc. What makes a great CM science? Living Books, Fulbright books for info?, AND experiments to make it come alive! I love Aurora Lipper that comes in my email box. I love the online classes she does. That would be neat in other area’s of science.  I only get what she is up to but haven’t signed up for any online classes but she is only physics…such as rocketry, aero dynamics etc. and this is something they aren’t interested in at all though they might need to know a few basic things.

Any ideas out there

Thank you so much.
