It looks cute... just from what they say on the website I can't tell exactly what it covers, but I think I'd be hesitant to call it high school level with "kitchen" labs.
It looks like it covers about what I do in my two-week half-day chemistry camp, but not a whole year course. Not so much because of the topics (the number of topics are probably almost the same -- how far into each topic you go is going to be the defining factor for what level it is...)
The limits I see are that it doesn't have any acids and bases except vinegar, lemon juice, ammonia and baking soda... there's only one lab on reaction energy which uses purchased hot and cold packs instead of chemicals... nothing on reactivity of metals... only a tiny bit on qualitative analysis and nothing on quantitative... no redox or electrolysis...
That all doesn't make a bad curriculum - there's definitely a niche for chemistry that doesn't blow up the house, especially with younger kids. But I would want most of those other things to call it high school, and lab experience in something heavier than just cooking.
