  1. C: protein. Pollinators get food, and the flowers get their pollen moved. Both sides win. Source: USDA Forest Service
  2. A: condensation. You can see condensation when drops form on the outside of a cold glass. Source: NASA Science for Kids
  3. A: chlorophyll. It is the most common pigment in a leaf, which is why most leaves look green. Source: National Park Service

For the host

Take the round outside: every little-band question can be answered by looking at a real plant.

  • Read each question and its three answers aloud, or press ▶ Play and Peabody reads them; a tap shows the answer, a line about it and where it comes from.
  • On a phone, pass it round: one question per team, a star for each right answer. On a laptop or a TV, press 📺 Big screen.
  • On paper, print the cards, one answer sheet per team and the key on its own page.

Where these questions come from

Each question was written by Peabody in its own words and checked against one page, named under its answer. The pages we used for these rounds:
