Cell Structure
Select sample cells from a plant or animal and place the cells on a microscope to look inside the cells. Information about their … common structures is provided (and the structures are highlighted), but you will need to move your microscope slide to find all the different structures.

Cell Division
Begin with a single cell and watch as mitosis and cell division occurs. The cells will go through the steps of interphase, … prophase, metaphase, anaphase, telophase, and cytokinesis. The length of the cell cycle can be controlled, and data related to the number of cells present and their current phase can be recorded.

Cell Energy Cycle
Explore the processes of photosynthesis and respiration that occur within plant cells. The cyclical nature of the two processes can … be constructed visually, and the photosynthesis and respiration equations can be balanced in a descriptive and numerical format.

Diffusion
Explore the motion of particles as they bounce around from one side of a room to the other through an adjustable gap or partition. The mass … of the particles can be adjusted, as well as the temperature of the room and the initial number of particles. In a real-world context, this can be used to learn about how odors travel, fluids move through gaps, the thermodynamics of gases, and statistical probability.

Osmosis
Adjust the concentration of a solute on either side of a membrane in a cell and observe the system as it adjusts to the conditions … through osmosis. The initial concentration of the solute can be manipulated, along with the volume of the cell.

Dehydration Synthesis
Build a glucose molecule, atom-by-atom, to learn about chemical bonds and the structure of glucose. Explore the processes of … dehydration synthesis and hydrolysis in carbohydrate molecules.
-
Paramecium Homeostasis
Observe how a paramecium maintains stable internal conditions in a changing aquatic environment. Water moves into the organism by … osmosis, and is pumped out by the contractile vacuole. The concentration of solutes in the water will determine the rate of contractions in the paramecium.
-
Virus Lytic Cycle
Release a lytic virus in a group of cells and observe how cells are infected over time and eventually destroyed. Data related to the number … of healthy cells, infected cells, and viruses can be recorded over time to determine the time required for the virus to mature within a cell.
