Element Groups (Materials for up to 8 Groups)

The activities in this kit focus on developing a better understanding of why periodic trends occur in the elements. Students will perform two sets of experiments, one focusing on the alkaline earth metals, and the other focusing on halogen groups. In the first set of experiments, students search for patterns as they look at the reactivity of the alkaline earth metals. The second set of experiments form small amounts of solubilized halogen gases as a colorful way of measuring reactivity within the halogen group. Kit contains enough materials for 8 groups. Safety data sheets, teacher's manual, and student study guide copy masters are included.
