Heart Structure & Double Circulation means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A simple body outline printout or drawing; Pencil and labels. 1. Say the goal of Heart Structure & Double Circulation in plain words once. 2. Adult points to one organ or system and names its job in plain words. 3. Child labels three parts and says the job of each. 4. Fresh check: one fresh organ/system job. Record and stop. Done: three correct labels with a job sentence each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.
