During the Summer we had a decent sized vegetable garden.  The kids would help me with the harvest and watering (but tended to run the other way when it came to the weeding).  We grew and canned a pretty good variety of items, and everything was started from seeds here in the house or in the ground itself.

They saw how tiny one tomato seed it, watched it grow in a little cup, transpanted to a larger cup then a larger planter, then planted into the garden.  They started counting how many tomatoes were picked off of their plant but stopped because there were just so many!

We participated in Tomatosphere and learned about space exploration and the possiblity of gardening on Mars.  We read books on Mars, NASA (although this program is sponsered by the Canadian space program), read through all of the tomatoshpere website.  We are doing it again this year, but trying to to some different things than we did last year.  They are monitoring their seeds daily, keeping track of them on a graph chart and in a gardening journal.  We will transplant these into our garden when it is time.

The kids also helped this Fall with the preserving process - dehydrating, freezing and canning.  Since I'm new to this, we all studied together how to do each process and which process if best for our needs.  They still make comments when we open a jar of vegetables or they thaw a pack of jerky, it's been lessons that have really stuck with them.
