How it works
Kids ask why all day, so each of these 150 science trivia questions for kids carries its reason under the answer. They split evenly over five branches, 30 each: animals, the human body, space, weather and materials. One asks which rock floats on water.

What each branch asks
Animals runs from which group feeds its babies milk to how a blue whale strains its food. The human body covers the heart, lungs, senses, teeth and joints. Space goes from the smallest planet to the light the James Webb telescope sees. Weather names the clouds, the storm scales and a weather station's instruments. Materials asks what glass, steel and pencil lead are made of, and why wood floats.

Questions and answers
What ages are these science questions for?
Ages 6 to 12. About a third are easy by our estimate, such as how many lungs you have. A hard one asks what kind of giant planet Uranus is. For science questions for 3rd graders, start on The human body.
Which rock floats on water?
Pumice. It is a light volcanic glass so full of gas bubbles that many pieces float, sometimes for years, until they fill with water and sink. It forms when frothy lava is thrown out of a volcano and cools fast. The question is in Materials.
How is this different from the general kids' trivia pack?
That pack mixes animals, space and the body with geography, sports rules and the seasons. This one is science only, with branches on weather and materials. The two were written as separate sets, though an answer such as carbon dioxide turns up in both.
