This lesson focuses on adaptations as a driving force in evolutionary diversity. Adaptations are characteristics within a species that enhance its chances of survival and reproduction. Adaptations can be behavioral, structural, or functional. Students must understand that these adaptations are not acquired in the course of the organism’s lifetime, but are inherited traits that have been passed down
How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
