Observing Mitosis
Students prepare, then view under the microscope, slides of an onion root tip in which cells have undergone various stages of mitosis. They sketch and differentiate interphase and four major stages of mitosis – prophase, metaphase, anaphase, and telophase.

Scientific Concepts
•The cell cycle describes the process of creating new cells.
•When a cell duplicates to form two identical daughter cells, the cell cycle consists of two main steps: interphase and mitosis.
•Mitosis is a continuous process that scientists have divided into five phases: prophase, metaphase, anaphase, telophase, and cytokinesis.
Key Vocabulary: anaphase, interphase, prophase, cell cycle, metaphase, telophase,
cytokinesis, mitosis

Kit #61Plant Cell StudyThis simple, step-by-step lab activity provides a sense of realism and participation that commercially prepared slides or illustrations can't possibly duplicate. Students prepare slides using pre-cut monocot and dicot plant cross sections and macerated stem tissue. After staining and mounting the samples, students then view their slides through a microscope. Students use clearly...

Kit #79Strawberry DNA
This lab activity allows students to easily extract and observe deoxyribonucleic acid (DNA) found in plant cells. They separate and spool the DNA so they can observe some of DNA’s physical properties. Students gain an appreciation and firsthand experience of the DNA structure. This lab activity comes with everything needed to perform...

Kit #71DNA Model
The two activities in this kit introduce students to the structure of the DNA molecule and how its structure allows it to replicate. Using a unique Lab-Aids modeling set, students first build an 8-rung DNA double helix and learn the base-pairing rule. Then starting with a 4-rung segment, they unzip the ladder and create...

Kit #908SCancer and the Cell Cycle
Students play a board game that simulates the cell cycle, with each student in a group of four taking the role of a specific type of cell. As they progress through the cycle, students learn about the phases and events of the cycle.
