🎯 Make a trivia round

Big round (ages 12 and up): 🌳 Plants and trees · 🌦️ Weather. Ten questions. Tap a box to see the answer.

How many teams?

Teams are 🦊 Foxes, 🐻 Bears, 🦉 Owls, 🐸 Frogs. Take turns: one question each, and a star for every right answer.

Send this round to another host: its address is the round, peabody.kids/trivia/round?r=b3.tplants*8,weather*2.s367. It has the age, the themes and a number in it, and nothing about who is playing.

  1. A: chemosynthesis. It feeds life in the dark deep ocean, where no plants can grow. Source: NOAA Ocean Exploration
  2. C: wind shear. Wind shear helps set up the spinning air inside storms that can form tornadoes. Source: NOAA NESDIS (SciJinks)
  3. B: mycelium. The single strands are called hyphae, and a network can be tiny or miles wide. Source: National Park Service
  4. C: no, it changes from snow to snow. Snow scientists say the ten-to-one rule is not always right: snow holds different amounts of water. Source: National Snow and Ice Data Center
  5. A: almost 80%. Visits from bees and other pollinators also give bigger, tastier fruit. Source: USDA Forest Service
  6. C: an enzyme. Once the green is gone, yellow and orange pigments that were hidden show through. Source: National Park Service
  7. A: about 1 to 1.5 inches. Saguaros grow so slowly that an adult is about 125 years old. Source: National Park Service
  8. B: the stigma. The anther is the male part that makes pollen; the stigma is the female part that receives it. Source: USDA Forest Service
  9. C: the Jurassic. Redwoods have grown in their present range for about 20 million years. Source: National Park Service
  10. A: over 40 years. Long-lasting needles help the tree through years when it cannot grow new ones. Source: National Park Service

Make a different round

1. Who’s playing?
2. Tick up to three themes

Three themes give three questions each and a riddle to end on. One theme gives all ten. If you tick more than three, the first three count.

How the round maker works

  • Little is for ages 6 to 8 (kindergarten to 2nd grade), Middle for 9 to 11 (grades 3 to 5), Big for 12 and up. A round never mixes ages; at a mixed table, play one round per age on the same themes.
  • Three themes give three questions each and a riddle to end on. Two give five each, and one gives all ten. Shuffle keeps the age and the themes and draws ten new questions.
  • Every question about animals, the ocean, dinosaurs, space, planet Earth, weather, plants, the body and Thanksgiving was written by Peabody and checked against one page from NASA, NOAA, USGS, the Park Service, the USDA, the National Archives, the Smithsonian or another public source, named under its answer. Capitals come from each state’s USA.gov page, word meanings from Peabody’s word bank, and sums are worked out on the key.
  • The round’s address is the round, so you can send it, print it or play it again. Scores stay on this device. There is nothing to sign up for and nothing anyone types.
