Science Saturday – Respiratory System

Welcome to Science Saturday! Each Saturday, The Homeschool Scientist and link our Apologia Human Anatomy and Physiology posts together to give you ideas and resources for your science studies. This week, we are on lesson 6 – The Respiratory System.

This year, my daughter attends a weekly co-op where Apologia Human Anatomy and Physiology are offered. We love Apologia science so it is a good fit. However, since she is in a co-op setting, we are at the mercy of the co-op schedule. Usually, it works out fine. However, this week, we are a week behind our Science Saturday blogging schedule. Instead of showing you what we’ve done this week, I thought I’d share some of the activities we will do outside of the co-op next week to enhance our respiratory system study.

Videos – several respiratory system videos – animated cartoon about the respiratory system – animated video about the mechanics of the respiratory system
