Questions
Which feature helps a camel survive in a hot, dry desert?
- Fat stored in its hump

Show answer
Fat stored in its humpWhy do polar bears have thick fur and a layer of fat?

- To stay cool in the heat
- To stay warm in the cold
- To swim faster in rivers
Show answer
To stay warm in the coldA cactus has spines and a thick stem that stores water, which helps it live in a desert. (True or false?)
Show answer
TrueWhat are fossils?
- Living plants in old forests
- Remains or traces of living things from long ago
- Rocks made by volcanoes only
- Tools made by early people
Show answer
Remains or traces of living things from long agoFossils are usually found in which type of rock?
- Crystal rock
- Igneous rock
- Molten rock
- Sedimentary rock
Show answer
Sedimentary rockWhat can fossils tell us about living things of the past? (Answer out loud)
Show answer
What they looked like and that they lived long ago (they show how life has changed)All fossils come from animals that are still alive today. (True or false?)
Show answer
FalsePuppies in one litter look similar but not identical. What is this difference called?
- Adaptation
- Extinction
- Fossilisation
- Variation
Show answer
VariationWhy do offspring usually look like their parents?
- They copy their parents' habits
- They eat the same food
- They inherit features from their parents
- They live in the same place
Show answer
They inherit features from their parentsWhat word means passing on features from parents to offspring? (Answer out loud)
Show answer
Inheritance (heredity)In natural selection, which animals are more likely to survive and have young?
- The oldest ones
- The ones that are the biggest always
- Those best suited to their environment
- Those chosen by humans
Show answer
Those best suited to their environmentSome moths are darker than others. On dark tree bark, which moths are more likely to survive?
- Both survive equally whatever the colour
- Dark moths, as birds find them harder to see
- Neither, since moths cannot hide
- Pale moths, as birds see them easily
Show answer
Dark moths, as birds find them harder to seeOver many generations, what happens to helpful features in a species?
- They become more common
- They change in one lifetime
- They disappear quickly
- They stay rare forever
Show answer
They become more commonNatural selection happens because individual animals decide to change their bodies. (True or false?)
Show answer
FalseWhich scientist is famous for his theory of evolution by natural selection?
- Albert Einstein
- Charles Darwin
- Isaac Newton
- Louis Pasteur
Show answer
Charles DarwinDarwin studied finches with different beak shapes on which islands? (Answer out loud)
