Some animals survive better than others because they have traits that help them avoid predators or find food. Over time, these helpful traits become more common in the population.
What is natural selection?

What is being able to hide from predators?
This is a common practice of science where a student repeats an experiment several times with the same setup to see if the results are consistent.
What are trials?
Plants on the forest floor of a rainforest have much wider leaves than plants high in the canopy. Larger leaves allow for plants to have more exposure to this resource.
What is sunlight?
This phenomenon allows manatees to survive cold winters by moving to warmer spring waters where their bodies stay at a safe temperature.
What is migration?
Some green anole lizards (Anolis carolinensis) in a forest develop a new bright green scale coloration. These lizards hide better in leafy trees. Over time, lizards with this scale coloration are more likely to survive and become more common.
What is green?

What is a hypothesis?
A process defined as a plant sprouting from a seed or spore, usually after dormancy in a moist, dark area.
What is germination?
These adaptations allow a seed to disperse across environments via wind.
What are wings or fluff?
This characteristic would allow animals to BEST adapt to cold weather. Over time, animals with this adaptation is more likely to survive than those without.

What is migration?
In an experiment testing which lizard color survives best in a forest, scientists change the background color of the habitat to see which lizards hide from predators most successfully. The background color is an example of…
This response will happen when a plant is only exposed to sunlight from a certain direction.
What is growing towards the light?
This benefit comes from the adaptation that allows some animals, like certain amphibians, to have lungs and gills, so they can breathe in water and on land.
What is an expanded range to find food?
Rabbits in the Australian desert with slightly longer hind legs can jump faster and escape dingoes more easily. Over time, these rabbits have more babies than shorter-legged rabbits. Natural selection favors the rabbits with __________ hind legs.
What is slightly longer?
The name of an animal group that resides by the water, has wet skin, and lays eggs.
What is an amphibian?
Students want to see how water temperature affects how many insects tadpoles eat in one hour. Four groups of tadpoles were kept in tanks (A,B,C,D) with the same number of insects and same tank size, but the water temperatures (F) were different:
A 15 F 4 insects eaten
B 20 F 6 insects eaten
C 25 F 9 insects eaten
D 30 F 10 insects eaten
The conclusion that can be made about the effect of water temperature on tadpole feeding is that...
What is tadpoles eat more insects at higher water temperatures?
This type of plant is referred to as an angiosperm and produces seeds inside of a fruit for reproduction.
What is a flowering plant?
Some sea turtles usually migrate to lay eggs when ocean temperatures are just right. With warming oceans, one species now begins its migration earlier and stays longer in nesting areas.
What is a species adapting to its changing environment?
In a lake, trout are easily seen by predatory birds and eaten frequently. One day, a genetic mutation occurs and a spotted trout is introduced into the population, allowing for better camouflage with the lake bottom. The __________ trout will be naturally selected and become more common over time. (spotted or spotless)
What is the spotted trout?
