The Osseo School District is making changes to its teacher-led science demonstrations after four students were injured in a classroom accident at Maple Grove Junior High. In a 71-page report, the district says the methanol "flash bottle" demonstration will not be allowed pending further review. It also calls for a more stringent approval process for science demonstrations and a detailed list of approved demonstrations.
