Product Details

Deepen your students’ understanding of the factors that affect diffusion with this advanced-level study kit. Students will investigate how three variables influence the rate of diffusion of dye molecules in agar. Explore the quantitative effects of the concentration of the agar gel, the diameter of the test tube, and size of the dye molecule. A new twist on a classic scientific concept! Includes all necessary chemicals and consumable supplies, comprehensive student instructions, and Teacher Notes.

Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.

Performance Expectations

MS-PS2-3: Ask questions about data to determine the factors that affect the strength of electric and magnetic forces
MS-PS2-5: Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact
HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS2-5: Plan and conduct an investigation to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.
HS-PS3-5: Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction.
