This website contains great materials for laboratory activities. I think hands on activity is very important to understand variety of concepts in science. Even the middle school that I do my observation, I find out that students rememeber better on material that they did the lab. The website is well divided into categories so it makes user to easy to search. It also provide handouts in different format so I can open them up whatever format I want. Each activity has related questions that I can use for the review. I can always make refernece to it and create own activity as well. The activities usually include about one page or reading so that would also help students to deveople their reading skills as well.
