 Brainpop on Natural Selection
Vocabulary
Natural selection: those organisms with traits that are advantageous have a
greater chance of survival and passing on traits to offspring
Environmental Pressures: shortage of food, water, space, or risk of being eaten
Variation: physical or genetic differences, which can be due to genetic mutations
(changes)
Habitat: place where a plant or animal normally lives or grows
Temperature: how hot or cold something is
Climate: type of weather usually found in a part of the world
Energy: ability to move or do work
Equipped (equipment): have something that is needed
Moisture: small amount of liquid
Oxygen: gas in the air that all living things need

Chapter 1: Variation under Domestication
Q: How did farmers learn how to grow some of the best fruits, vegetables, or
livestock (pigs, sheep, chickens, horses, cows, etc.) around?
A: Farmers understood that they could control the features of the plants and
animals they grew (domesticated) by choosing carefully (selecting) how to breed
them.
