Sept. 3, 2020 Welcome to science class! Thursday, Sept. 3, 2020 I can analyze why organisms hibernate and migrate and why plants become dormant. Reading Essentials - Life Science: Chapter 13, 21 Big Ideas 1. Hibernation, migration, and dormancy are forms of cyclic behaviors. 2. Organisms migrate for food, reproduction, and bad weather. 3. Organisms hibernate due to lack of food and extreme weather. 4. Organisms become dormant due to extreme weather. ESSENTIAL QUESTIONS What is a behavioral cycle? Why do behavioral /responses occur in cycles? What is hibernation? How is its purpose different from dormancy? What is migration? Why do some organisms’ migrate while others do not? AGENDA ✔ Prezi - behavior adaptations ✔ Behavioral adaptations slides ✔ Vocabulary review ✔ Assignment- https://prezi.com/5olrijnhln9q/hibernationmigration-dormancy/ Behavioral adaptations ▪ Behavioral adaptations are actions that help an animal survive. ▪ They can be learned or instinctive. ▪ social behaviors ▪ behaviors for protection Pack Hunting vs. Loners ▪ Some animals benefit from helping each other by hunting in a pack. Herding ▪ Some animals find that there is safety in numbers. Nocturnal Some animals prefer the night! Diurnal ▪Active during the daytime. Hibernation – (winter) ▪ This is a period in which an animal’s body temperature drops, body activities are slowed to conserve energy. ▪ E.g. Bats, chipmunk & bears. marmot Estivation- (summer) ▪ A period of inactivity when animals retreat from heat or lack of water. (snake and tortoises) Arizona– Spade-foot Toad Building Structures Burrowing Some behavioral adaptations follow seasonal cycles. Migration ▪ Animals moving to Animals migrate for another location to ▪ different reasons. improve their ▪ better climate chances of survival. ▪ better food ▪ safe place to live ▪ safe place to raise young ▪ go back to the place they were born rufuos hummingbird Dormancy ▪ When plants drop their leaves due to harsh temperature, reduced sunlight or drought. During fall the plants prepare for dormancy. Dormant Deciduous – the kinds of plants that only have leaves during part of the year. Evergreens- the kinds of plants that have green leaves throughout the entire year. VOCABULARY Review ▪ Behavioral adaptations are actions that help an animal survive. ▪ Nocturnal - active at night ▪ Diurnal - active during daylight Hibernation a period in which an animal’s body temperature drops, body activities are slowed to conserve energy. (winter) Estivation a period of inactivity when animals retreat from heat or lack of water. (summer) Migration animals moving to another location to improve their chances of survival. Dormancy When plants drop their leaves due to harsh temperature, reduced sunlight or drought.
