Check the listing for details. Science Kit - Diffusion & Cell Size - Hands On Lab Activity - Innovating Science. Condition: New. Listed at 35.99 USD. Science Kit - Diffusion & Cell Size - Hands On Lab Activity - Innovating Science Why are cells microscopic? The answer relates to the need for the cell to effectively bring materials in and remove waste. In this activity, students will create simulated cells (agar blocks) of different sizes and examine how effectively a substance is able to diffuse into the cell in a set period of time. A special indicator in the cells will allow students to visualize the degree of diffusion. The results will clearly display the fact that a smaller volume creates a more favorable condition for the exchange of material across a cell membrane. Kit contains enough materials for 5 groups of students. Teacher?s Manual and Student Study Guide copymasters are included. Included in kit: 25g Agar 10mL Bromothymol Blue Concentrate 25mL Hydrochloric Acid, 2.0M 6 Agar Block Casting Trays 5 Plastic Cups 5 Plastic Knives 5 Plastic Stirrers Materials needed but not supplied Metric rulers Paper towels Distilled or deionized water (for pre-lab prep) For Laboratory Use Only. Not for drug, food, or household use. Keep out of reach of children. For more information, refer to the Safety Data Sheet.
