Falcons hunt during the day. They search for food from high in the sky. When they spot food, they swoop down at up to 180 kilometers per hour to capture it. Owls are different from falcons because they hunt at night. Even though they hunt at different times of the day, owls and falcons both use their eyes to find food. Falcons and owls take in and process visual images the same way. The picture shows how a falcon sees a chicken that it is trying to capture. Miguel recently bought some chickens that lay eggs. He keeps the chickens in his backyard. Miguel noticed a falcon circling over his yard during the day. When it got dark, Miguel noticed the falcon left. Instead, he saw an owl flying over the yard at night. Miguel is afraid the falcon or the owl will see his chickens and take them. Miguel begins brainstorming ideas to keep the larger birds from seeing the chickens in the backyard. If the hunting birds cannot see the chickens, they will not take them. Why does the falcon hunt during the day?
It is easier for the falcon to see.
It is easier for the falcon to hide from prey.
The falcon relies on its sense of hearing to hunt.
The falcon prefers to hunt when it is warm outside.

The falcon is able to see and respond to the chickens from high in the sky. Place the phrases in the correct order to show how this happens.
Light reflects off the chickens; The falcon swoops down to try to capture the chicken; Information is sent to the falcon's brain; Light enters the falcon's eyes.

Which statement most accurately compares wave 1 to wave 4?
Wave 1 has a taller amplitude than wave 4.
Wave 4 has a shorter wavelength than wave 1.
Wave 4 has a higher frequency and amplitude than wave 1.
Wave 1 has more energy than wave 4.
What is true about these waves?
The red wave has the longest wavelength , and lowest frequency. Therefore it has the lowest energy.
The purple wave has the highest frequency, therefore it has the lowest energy.
