Fortunately, this blog has a lot of entries for you to check out. Check out the Topic List to help you find the topic you need!
There isn't much money left in most 2014-2015 science department budgets. For inexpensive chemistry lab ideas, buy my lab book Chemistry on a Budget for $19.46 at amazon.com or $23 at lulu.com. It will take a few weeks to get to you, so order now!
This book contains 13 labs using consumable materials purchased from local stores. There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
By the way, I'd love to hear from you with new Topic ideas!
Have a good weekend!
