Page 1: DIFFUSION AND OSMOSIS. Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations. Drill: What do you think happens.

DIFFUSION AND OSMOSIS

Page 2: DIFFUSION AND OSMOSIS. Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations. Drill: What do you think happens.

Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations.

Drill:What do you think happens to a drop of food coloring when it is added to water and no one stirs it?

Diffusion

Particles moving from an area of high concentration to an area of low concentration.

Page 5: DIFFUSION AND OSMOSIS. Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations. Drill: What do you think happens.

Homeostasis

How our body stays balanced.

Page 6: DIFFUSION AND OSMOSIS. Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations. Drill: What do you think happens.

How does diffusion help us maintain homeostasis? Sugar/nutrients move into the cell

Removes waste out of the cell

Concentration Gradient

Particles moving from an area of high concentration to an area of low concentration.

Selectively Permeable

Small molecules can move through the membrane large particles cannot.

Osmosis

WATER moving through a cell membrane from an area of high concentration to an area of low concentration.

Page 10: DIFFUSION AND OSMOSIS. Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations. Drill: What do you think happens.

Passive Transport

Does not require energy for particles to move across a cell membrane.

Page 11: DIFFUSION AND OSMOSIS. Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations. Drill: What do you think happens.

Active Transport

When cells use ATP energy to move molecules across a membrane.

Page 12: DIFFUSION AND OSMOSIS. Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations. Drill: What do you think happens.

Active Vs. Passive Transport

Which picture shows active transport?

Solution Types

Page 14: DIFFUSION AND OSMOSIS. Objective: I will apply my knowledge of osmosis and diffusion to explain my lab observations. Drill: What do you think happens.

Stations

Using your notes complete the 5 station activities.

The stations are not in order You will have 8 minutes at each station Do not move until the buzzer sounds!
