Write narratives in which they recount a well-elaborated event or short sequence of events, include details to describe actions, thoughts, and feelings, use temporal words to signal event order, and provide a sense of closure.
Using the San Diego Zoo's Adaptations Connection guide (pp 31-34), write a story about what happens when a predator and prey animal meet, describing how the animal uses its special adaptation.
Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.
Color and cut out butterflies that are red, green and yellow (some the color of grass or indoor carpet, others in contrasting colors.) Scatter the butterflies on the grass or carpet and retrieve them within 15 seconds. Count and compare the number of camouflaged-colored butterflies collected with the number of contrasting-colored butterflies.
Multiply a whole number of up to four digits by a one-digit whole number, using strategies based on place value. Find whole-number quotients with up to four-digit dividends and one-digit divisors, using strategies based on place value.
Use this Amazing Animal Senses chart. Using facts comparing animal and human senses, determine how much more acute a particular animal's given sense is than a human's. Examples: catfish have 100,000 taste receptors and human have 10,000. Mice can hear frequencies of 1,000 Hz and humans can hear frequencies of 20 Hz. Elephants have 2,000 scent receptors and humans have 400.
Use observations to describe patterns of what plants and animals need to survive.
All living things need food and water to live and grow. Examples could include the different kinds of food needed by different types of animals, the requirement of plants to have light; and, that all living things need water.
Use materials to design a solution to a human problem by mimicking how plants and/or animals use their external parts to help them survive, grow, and meet their needs.
Different animals use their body parts in different ways to see, hear, protect themselves, move from place to place, and seek, find, and take in food. Examples of human problems that can be solved by mimicking plants or animal solutions could include designing clothing or equipment to protect bicyclists by mimicking turtle shells and animal scales; stabilizing structures by mimicking animal tails, keeping out intruders by mimicking animal quills, and detecting intruders by mimicking animal eyes and ears.
Make observations of plants and animals to compare the diversity of life in different habitats.
There are many different kinds of living things in any area, and they exist in different places on land and in water. Emphasis is on the diversity of living things in each of a variety of specific habitats.
Use evidence to construct an explanation for how the variations in characteristics in a species may provide advantages in surviving, finding mates, and reproducing.
Examples could be plants that have larger thorns may be less likely to be eaten by predators; and animals that have better camouflage coloration may be more likely to survive and therefore more likely to leave offspring. Populations of animals are classified by their characteristics.
Make a claim about the merit of a solution to a problem caused when the environment changes and the types of plants and animals that live there change.
Populations live in a variety of habitats, and change in those habitats affects the organism living there. When the environment changes in ways that affect a habitat, some organisms survive and reproduce, others move to new locations, others move into the transformed environment, and some die.
Construct an explanation based on evidence that describes how genetic variation of traits increase some individuals' probability of surviving and reproducing in a specific environment.
Natural selection leads to the predominance of certain traits in a population, and the suppression of others. Emphasis is on using concepts of natural selection like passage of time, selection of favorable traits, and heritability of traits.
Use mathematical representations to support explanations of how natural selection may lead to increase and decreases of specific traits in populations over time
Adaptation by natural selection acting over generations is one important process by which species change over time in response to changes in environmental conditions. Traits that support successful survival and reproduction in the new environment become more common; those that do not become less common. Emphasis is on using mathematical models, probability statements, and proportional reasoning to support explanations of trends in changes to populations over time. Examples could include peppered moth population changes before and after the industrial revolution.
Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in its populations. Emphasis is on recognizing patterns in data and making warranted inferences about changes in populations, and on evaluating empirical evidence supporting arguments about changes to ecosystems.
Evaluate competing design solutions for maintaining biodiversity and ecosystem services.
Biodiversity describes the variety of species found in Earth's terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem's biodiversity is often used as a measure of its health.
