Matter: It’s in the Bag! from Beaker & Book includes activities and investigations for exploring these properties:
• Relative mass (lighter or heavier)
• Relative density (sink or float)
While some investigations are informal, descriptive investigations that simply involve “sorting and reporting” in a whole-group discussion, others involve collection of data by writing or drawing.
Eight recording sheets provide ways for students to record their findings. Teacher tips for facilitating investigations with little learners are included.
