This activity is a brief introduction to adaptations as the group observes a live organism together. Adaptations are inheritable structures and behaviors that help a group of organisms survive in their habitat. Students start out observing an organisms’ structures, trying to figure which might help it survive in its habitat and which are inheritable. Then, they do the same with behaviors: attempting to figure out which ones are behavioral adaptations. To build understanding of a complex concept like adaptations, students need multiple exposures to it, which is why this activity should be followed by other adaptations-focused activities.

In this unit of study students learn about adaptations and how they help animals survive. They will apply this knowledge to design new technologies. This unit integrates nine STEM attributes and was developed as part of the South Metro-Salem STEM Partnership's Teacher Leadership Team. Any instructional materials are included within this unit of study.

This is a lesson plan designed to teach students science standard 2 Standard 2.2.2Plan and carry out an investigation of the structure and function of plant and animal parts in different habitats. Emphasize how different plants and animals have different structures to survive in their habitat. Examples could include the shallow roots of a cactus in the desert or the seasonal changes in the fur coat of a wolf. (LS1.A, LS4.A, LS4.D)Students will demonstrate their knowledge by creating a newsletter using the Apple Pages app.

Students tend to be fascinated by colors and patterns of organisms, and by thinking and learning about these and other adaptive strategies. Colors and patterns in nature are a great entry point to understand adaptations. This activity focuses on how organisms’ patterns and colors help them stand out or blend in with their environment, and how this helps them survive. Students observe the main colors in the landscape, then search for plastic animals hidden there, noticing which blend in with their surroundings and which stand out. Then, students discuss what made the animals blend in or stand out, construct explanations for how this could help the animals survive, and learn four categories for color and pattern adaptations: camouflage, mimicry, warning, and attraction. Students apply these concepts as they search for real organisms in the area, then discuss how patterns and coloration might help the organisms survive in their habitat.

Bug Hunt uses NetLogo software and simulates an insect population that is preyed on by birds. There are six speeds of bugs from slow to fast and the bird tries to catch as many insects as possible in a certain amount of time. Students are able to see the results graphed as the average insect speed over time, the current bug population and the number of insects caught. There are two variations to try for the predator, one where the predator pursues the prey and one where the predator stays still and captures insects that pass nearby. In the first case the bird catches the slow insects and the faster ones survive, reproduce and pass genes on. The average speed of bug should increase over time. In the second case the faster bugs come near to the bird more often than the slow ones. The slow ones survive more, reproduce and pass their genes on.

In this article, the author identifies science content standards for grades K-5 from the national standards that are aligned with the third essential principle of the climate sciences--life on Earth depends on, is shaped by, and affects climate. In addition she reviews misconceptions commonly held by children about adaptations and natural selection. The free, online magazine Beyond Weather and the Water Cycle is structured around the seven essential principles of the climate sciences and explores a different principle each issue.
