Home-school science curriculum using cooking
Those sound like fairly specific and advanced topics for the age range provided.  These standard guidelines might help you with a way to think about how to approach this. With some knowledge about what kids should learn at various levels, you can determine how kitchen experiences could meet those needs.
I don't know if this question will remain open.  In fact, you might get better answers here by posing a question like: How can I use the making of ice cream to illustrate the concept of states of matter?
Anyhow....I think you need to begin more broadly at first, then drill down with the help of curriculum guides.
Concepts that could be addressed in the kitchen:
The scientific process
Observation
State of matter
Chemical reactions
Mass, volume, forms of measurement
Acids and bases
basic math
fractions
conversions
