Osmosis Prompt

Focus Questions: How does osmosis affect the concentration of different substances in the blood? Why is important to maintain homeostasis in the blood?

Assignment: Make a claim as to what is happening to the patients’ cells in the case of diabetics and Jennifer Strange. Use evidence from the egg model, your POGIL activity, and internet research to support your claim. Also, answer the bolded questions you find within the prompt. Provide reasoning to support your claim and evidence.

  1. People with diabetes tend to suffer from extreme thirst and frequent urination. These symptoms are signs that the body is not in homeostasis. How is the body trying to regulate its blood sugar levels?
  2. Jennifer Strange died from hyponatremia after drinking extreme amounts of water without eliminating urine. What is hyponatremia and how does it relate to Strange’s symptoms?

Use some of the following vocabulary in your answer: hypotonic, hypertonic, isotonic, concentrated, dilute, solute, solvent, osmosis, and diffuse/diffusion.

Activities/Assignments for 12/16 B Day

We finished up the POGIL activity on Membrane Structure and discusses the final Model on Active Transport.

We then developed a graphic organizer (Venn) that compared Passive Transport and Active Transport.

For the powerpoint that reviews cell membrane structure, passive transport (diffusion, osmosis, facilitated diffusion,) and active transport, Click osmosis+and+Diffusion

We then discussed osmosis.Here is the handout. Osnotes.

Here are the practice problems we worked on: Osmosis_worksheet[1]

Osmosis Videos/Demonstrations

We want to use the Egg Osmosis demonstrations to explain the symptoms of the disease diabetes and why a women died from drinking too much water during a radio contest.

Two of the symptoms of diabetes are thirst and excessive urination. What happens in your body to cause this? What does is have to do with osmosis?

We will place a decalcified egg in pancake syrup to find out.

A women named Jennifer Strange wanted to win a Wii for her family back in 2007 when they were hard to get. (Remember that?) The contestants had to drink an excessive amount of water and the last person to urinate won the prize. Jennifer finished second but later passed away from a condition called hyponatremia. What happen inside Jennifer’s body  and how does it have to do with osmosis?

We will place a decalcified egg in distilled water to find out.
