Activity 2-1: Making a Cell Model

PLAN

Summary Students begin by drawing a picture of a cell and labeling its parts. They use their drawings as a blueprint to design and construct a 3-D model of a cell. Students explain the function of each part of the cell model.

Objectives

Students:

\checkmark draw an accurate picture and identify the parts of a cell.

\checkmark design and construct a three-dimensional model of a cell.

\checkmark explain the function of each part of their cell model.

Student Materials

  • Activity Report
  • Determined by each team, with teacher approval

Teacher Materials

  • Activity Report Answer Key
  • Be sure to guide students to select materials that will not spoil.
  • Cell parts or organelles can be represented by a variety of materials, such uncooked pasta; dried fruit; plaster of paris or clay models.
  • Possible materials for the cell membrane include a shoe box, plastic jug, or plastic bag.
  • Cell models, diagrams, and/or charts

Advance Preparation Allow ample time for students to collect their own model materials and to add other materials as needed. Plan ahead for storage of completed cell models.

Estimated Time One class period

Interdisciplinary Connection

Art Invite the art teacher to help students select and collect materials for their models. Completed models can be displayed in the art class or in the art display area for the school.

Prerequisites and Background

Students need to be familiar with eukaryotic cell parts and their functions.

IMPLEMENT

Steps 1-5 This activity can be assigned as an individual project to be completed at home or as a class activity for groups or individual students. Make sure students get your approval of the materials they select to use in building their model cells.

Extend Activity 2-1 by having students create a board game based on the cell structures and functions.

ASSESS

Use the designs of the cell models and the written answers on the Activity Report to assess if students can

\checkmark design and build an accurate 3-D model of a cell.

\checkmark identify the parts of a cell.

\checkmark explain the function of each part of the cell model.
