    From Molecules to Organisms: Structures and Processes

Students who demonstrate understanding can:

Performance Expectations

  1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction. 4-LS1-1

    Clarification Statement and Assessment Boundary

A Peformance Expectation (PE) is what a student should be able to do to show mastery of a concept. Some PEs include a Clarification Statement and/or an Assessment Boundary. These can be found by clicking the PE for "More Info." By hovering over a PE, its corresponding pieces from the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts will be highlighted.

Science and Engineering Practices

Disciplinary Core Ideas

Crosscutting Concepts

By clicking on a specific Science and Engineering Practice, Disciplinary Core Idea, or Crosscutting Concept, you can find out more information on it. By hovering over one you can find its corresponding elements in the PEs.

  • Beauty and the Beak

    Through this educational guide and the nonfiction picture book Beauty and Beak by Deborah Lee Rose,  students learn how science, technology, and a 3D-printed beak rescued a bald eagle. Beauty and the Beak tells the story of a bald eagle whose be ...

  • Eat Like a Bird

      Eat Like a Bird is the January lesson of a series of 10 monthly Feathered Friends lessons created by the Cornell Lab of Ornithology and Pennington Wild Birds. The lesson focuses on bird beak forms and the type of food each bird has evolved ...

  • Fish Fun

  • What's the Buzz on Bees?

    This unit is comprised of a series of lessons that follow the 5E model, providing students with opportunities to learn about pollination on different levels. Studying the structures and functions of flowers and bees through text, video, and observati ...

  • Track a Plant's Movement

    In this activity, students monitor the position of plants to find out whether or not they change position in response to a change in sunlight. By measuring the distance from a leaf to a sunny window, students can generate data to prove plants move to ...

  • Who Is Your Champion?

    This article from NSTA's Science and Children outlines a series of lessons on structure and function, with an extension lesson that incorporates related engineering design. Students are guided to observe ants in their natural habitat, experiment ...

  • European Wasp vs. Bull Ant - Phenomenon

    This short, high-definition video shows a struggle between a wasp and an ant in extreme closeup. After viewing, students should be able to make inferences about the functions of certain specialized structures of each insect and support their ideas wi ...

  • Chew, Bite, Chomp

    This activity, created by the California Academy of Sciences, gives students the opportunity to explore the relationship between the structure of their teeth and their various functions. The students eat different types of food, consciously noti ...

  • Designer Ears: Biology & Perception Science Activity

    This short activity, one of many "Science Snacks" from the Exploratorium science museum in San Francisco, provides students with an opportunity to create ear structures that model the ears of familiar animals and explore how ...

  • Animal Mouth Structures

    In this activity students examine how the structure of various animal mouthparts affects their function. They will have an opportunity to predict what foods are likely to be eaten by birds with different beak types, watch a video compa ...

  • Seed Dispersal

    In this series of activities, students collect and observe different types of seeds and hypothesize about how they might be dispersed. They also investigate the design of seeds that use a helicopter method of wind dispersal, which offers an oppo ...

  • Bringing Your Classroom to Life

    This article from the March 2015 issue of Science and Children (which focuses on the Crosscutting Concept of Structure and Function), provides detailed plans for a lesson sequence on structure and function for upper elementary students. It incorporat ...

  • Feeding Frenzy

    In this activity, students experience the difficulty of trying to gather food with an ineffective model of an insect mouthpart, and then investigate how effective various insect mouth structures are for gathering different food sources. 

  • Animal Mouth Structures

    In this activity students examine how the structure of various animal mouthparts affects their function. They will have an opportunity to predict what foods are likely to be eaten by birds with different beak types, watch a video compa ...

  • Create Your Own Insect

    Students learn about insect body structures and their functions through print materials and a video, and then design their own insect to demonstrate understanding of essential life processes.
