Scientific investigations should be based on ________ and ________ rather than opinions.
SC.5.N.1.6
evidence and observations
The movement of water between Earth’s surface and the atmosphere is called the ________ ________.
SC.5.E.7.2
water cycle

Mrs. Nelson is demonstrating to her class how to use physical properties to identify minerals. She taps a piece of graphite with a hammer, and the graphite splits into thin sheets. Which property is the teacher demonstrating? SC.4.E.6.2
Cleavage
Explain how a scientist might revise a hypothesis after an experiment. Include why this is important.
SC.5.N.1.3
if results don’t support the hypothesis, scientists use evidence to change or improve it. This helps make scientific understanding more accurate.
Explain how Earth’s tilt affects seasons.
SC.5.E.5.1
Earth’s tilt causes different parts of the planet to receive more direct sunlight at different times of the year, leading to seasonal changes.
Describe the difference between a physical change and a chemical change, and give one example of each.
SC.5.P.9.1
Physical change = change in form (melting ice). Chemical change = new substance formed (burning wood).
Explain how different body systems work together to keep a human alive.
SC.5.L.14.1
Students should describe interaction (e.g., respiratory brings oxygen, circulatory transports it, digestive provides nutrients, etc.).
A scientist is observing behavioral adaptations of a North American porcupine. The porcupine is a mammal that climbs trees and has hardened fur called quills on its back and tail. All of these are used for protection. Which of the porcupine's adaptations is best described as a learned behavior rather than an inherited behavior? SC.4.L.16.3
climbing the tree for protection
