He's one of the best teachers I have had.I think he deserves more respect than he gets.
If you plan on taking chemistry in college, take all of Mr. Ketz's chemistry classes in high school, you will be glad you did. If you're scared to ask questions you need ot grow up
Really good teacher. Likes Steely Dan, which makes him all the cooler. I got along well with him, even though I didn't do that well in his class.
As far as science teachers go he was one of the best science teachers I've ever had. As long as you work and follow directions then the class isn't too bad.
moody man, dont pick up the stapler, too scared to ask ?s
Had excellent hearing!! Great teacher! Made things fun!!
