<p>
	The two activities are ideally completed in chronological order. The <a href="http://participatoryscience.org/mercury-watersheds/classroom-activities-research-questions-and-hypotheses">Research Question and Hypothesis activity</a> is primarily a brainstorming process. The <a href="http://participatoryscience.org/mercury-watersheds/classroom-activities-peer-review">Peer Review activity</a> allows different research groups to review each other&#39;s work.</p>
<p>
	Additionally, we have two activities to support the video Peer-to-Peer Claim Sharing on <a href="http://vimeo.com/">vimeo</a>- the Scientific Claim Proposal Video and the Scientific Claim Video Review. Video peer review allows students from different school to share and review each other&#39;s claims. This is an excellent way for students to solidify their thinking for a broader peer audience.</p>
<p>
	We suggest having a question board or an &quot;I know, I think&quot; board in the classroom to help the class refine their model and therefore their claim.</p>
