Student Exploration Osmosis | Gizmo Answer Key Pdf

Then he looked back at his Gizmo. He dragged the slider for “Left solute concentration” from 50 to 80 molecules. The pressure gauge on the left side of the virtual beaker began to climb. The blue water dots rushed across the membrane so frantically it looked like a river.

“Yes!” Leo said, clicking on the data box. The “Initial” molarity on the left was 1.0 M. On the right, 0.0 M. After a few simulated minutes, the left side had swelled slightly, and the molarities were moving toward equilibrium: 0.67 M on the left, 0.33 M on the right.

He closed the answer key PDF. The temptation faded, replaced by a quiet satisfaction. He typed his own answer to Question 5: Explain how a plant cell in a hypertonic solution loses turgor pressure. Student Exploration Osmosis Gizmo Answer Key Pdf

He hit “Check Answer.” A green checkmark appeared.

“Okay,” Leo muttered, clicking the “Start” button on the Student Exploration: Osmosis simulation. “Time to see who moves where.” Then he looked back at his Gizmo

The screen glowed a sterile blue in the dim light of Leo’s bedroom. On it was the Gizmo—a virtual beaker divided down the middle by a semi-permeable membrane. On the left side, he had loaded a solution of 50 glucose molecules and 50 water molecules. On the right, just 100 water molecules. The blue water dots rushed across the membrane

He had a PDF open in another tab—the dreaded Student Exploration Osmosis Gizmo Answer Key . His teacher, Ms. Albright, had posted it as a “study resource,” but Leo knew it was the Holy Grail for procrastinators. It contained all the answers: the “Prior Knowledge Questions,” the “Gizmo Warm-up,” and the five “Activity B” questions about water potential.

His fingers hovered over the trackpad. Just a peek. Question 3: If you were to increase the solute concentration on the left side, what would happen to the net movement of water?
