Episode notes
Clocks Change Not Sunlight
- Daylight Saving Time shifts our clocks, not the amount of sunlight we receive each day.
- Molly Bloom and Ava explain we control schedules so moving clocks gives more evening light but doesn't 'save' daylight itself.
Earth Tilt Explains Seasonal Day Length
- Seasons and day length come from Earth's tilt and orbit, not distance from the sun.
- Sandin's golf-ball-in-front-of-a-light example shows tilt makes northern hemisphere get longer summer days and shorter winter days.
Mystery Sound Is Spoon Stirring Tea
- The show includes a Mystery Sound segment where the hosts guess everyday noises to engage listeners.
- Ava and Molly repeatedly guess utensils and bowls before revealing it was a spoon stirring tea in a teacup.
