This is a stations lab where students move throughout each mini experiment and make observations. There are 7 stations total, each with inexpensive/common supplies. The questions are simple: what are your observations and how would you explain what you happened. This is great to do after gas/pressure relationships and the laws have been discussed, so they can use that knowledge to explain what is happening in the station. The lab worksheet is 5 page. The last page is a teacher prep page and simple includes the materials needed at each station.
