Students in the fourth through sixth grades throughout Marin entered 115 projects in the annual Marin County Elementary Science Fair sponsored by the Marin County Office of Education.

The projects were on display Tuesday at Vallecito Elementary School in San Rafael. Students developed a hypothesis, tested that hypothesis through data collection and analysis and then developed conclusions based on their investigations.
