The resources above correspond to the standards listed below:

Rhode Island Standards

RI.LS1. Life Science: All living organisms have identifiable structures and characteristics that allow for survival (organisms, populations, & species).
LS1 (K-4) FAF-4. Identify and explain how the physical structures of an organism (plants or animals) allow it to survive in its habitat/environment (e.g., roots for water; nose to smell fire).
LS1 (3-4)-4. Students demonstrate understanding of structure and function-survival requirements by...
4a. Identifying and explaining how the physical structure/characteristic of an organism allows it to survive and defend itself (e.g. of a characteristic-the coloring of a fiddler crab allows it to camouflage itself in the sand and grasses of its environment so that it will be protected from predators).
4b. Analyzing the structures needed for survival of populations of plants and animals in a particular habitat/environment (e.g. populations of desert plants and animals require structures that enable them to obtain/conserve/ retain water).
LS1 (K-4) POC-3. Predict, sequence or compare the life stages of organisms-plants and animals (e.g., put images of life stages of an organism in order, predict the next stage in sequence, compare two organisms).
LS1 (3-4)-3. Students demonstrate an understanding of reproduction by...
3a. Observing changes and recording data to scientifically draw and label the stages in the life cycle of a familiar plant and animal.
3b. Sequencing the life cycle of a plant or animal when given a set of data/pictures.
3c. Comparing the life cycles of 2 plants or 2 animals when given a set of data/pictures.
LS1 (K-4) SAE-2. Identify the basic needs of plants and animals in order to stay alive. (i.e., water, air, food, space).
LS1 (3-4)-2. Students demonstrate understanding of structure and function-survival requirements by...
2a. Observing that plants need water, air, food, light and space to grow and reproduce; observing that animals need water, air, food, and shelter/space to grow and reproduce.
LS1 (K-4)-INQ+POC-1. Sort/classify different living things using similar and different characteristics. Describe why organisms belong to each group or cite evidence about how they are alike or not alike.
LS1 (3-4)-1. Students demonstrate an understanding of classification of organisms by...
1c. Recording and analyzing observations/data about external features (e.g., within a grouping, which characteristics are the same and which are different).
RI.LS3. Life Science: Groups of organisms show evidence of change over time (structures, behaviors, and biochemistry).
LS3 (K-4) SAE-7. Using information (data or scenario), explain how changes in the environment can cause organisms to respond (e.g., survive there and reproduce, move away, die).
LS3 (3-4)-7. Students demonstrate an understanding of equilibrium in an ecosystem by...
7a. Explaining what plants or animals might do if their environment changes (e.g., changing food supply or habitat due to fire, human impact, sudden weather-related changes).
