Mini Bell Ringer

Based on your sequence (Cell Transport → Pacific NW Energy Flow → Cell Respiration Activity → PhET → Exit Ticket), students already understand:

✔️ Producers vs. consumers and where glucose comes from

They know kelp makes glucose and animals eat it.

✔️ Diffusion (including O₂ diffusion)

The PhET simulation directly rehearses this.

✔️ ATP comes from glucose

This appeared in their “metabolize glucose” setting in the simulation, even if it was abstract.

✔️ Body system connections

Your activity includes respiratory → circulatory → cellular respiration.

These pieces are enough to complete the Cell Respiration & Homeostasis exit ticket.

“Glucose does NOT become ATP inside the membrane — it is broken down inside the mitochondria during cellular respiration.”

Fix:

✔ glucose entering the mitochondria

✔ glucose breaking apart

✔ energy captured in ATP

Students know ATP exists but might not know how glucose → ATP happens.

The PhET simulation never visually shows:

“All living things do cellular respiration. Only producers do photosynthesis.”

Fix:

“Plants do photosynthesis”

“Animals do respiration”

They forget plants ALSO do cellular respiration.

Many students think:

“Does oxygen need ATP to enter cells? Why or why not?”

Fix:

Especially if they saw Na⁺/K⁺ pumps in the sim right before learning about O₂ movement.

You have completed the Mini Bell Ringer. Now go pick up a green sheet from the basket. Use the following slides to fill out the necessary information about "How producers get glucose to cells".
