  3. You can't see most damage (5 min)

Part 2: Storage science

Temperature, light, moisture, freeze-thaw.

  1. Temperature and the cold chain (6 min)
  2. Light, moisture and air (5 min)
  3. Freeze-thaw: why freezing isn't free (5 min)

Part 3: Reconstitution as a lab concept

Diluents, concentration math, sterile technique principles.

  1. What reconstitution is, and what diluents do (6 min)
  2. Concentration: the idea behind all the math (6 min)
  3. Sterile technique as a set of principles (5 min)

Part 4: Units vs. mL

Syringe literacy as a safety lesson.

  1. What a "unit" on a syringe actually is (6 min)
  2. How unit and mL mix-ups cause big errors (6 min)
