The video tutorial guides students through an experiment involving an eye model. Initially, students observe how light affects the eye. They then gather supplies and prepare their eye models, focusing on creating a pupil card. The experiment involves projecting images onto the retina using the eye model. Students are assigned roles as 'focuser' and 'pupil master' to conduct the experiment, observing changes as the pupil card is manipulated. The session concludes with a class discussion on the observations and results.

What is the first step students should take after watching the eye and light demonstration?

• Discuss the video as a class

• Cut out the pupil card

• Start the second part of the experiment

• Color the iris of the eye model

What supplies are needed for the second part of the experiment?

• The eye model from a previous activity

• A new eye model

• A magnifying glass

• A flashlight

What should students do with the iris of the eye model?

• Color it with a new color

• Leave it blank

• Color it with the same color as before

• Cut it out

Before using the pupil card, what should the teacher do?

• Turn on the lights

• Turn off the lights and uncover windows

• Hand out new supplies

• Explain the next steps

What is the role of the 'pupil master' in the experiment?

• To color the iris

• To cut out the pupil card

• To slide the pupil card into the pocket

• To make a sharp picture on the retina

What should the 'focuser' do once the pupil card is in place?

• Color the iris

• Cut out the pupil card

• Turn off the lights

• Make a sharp picture on the retina

What should both students observe while the pupil master pulls out the card?

• The size of the pupil

• The sharpness of the picture on the retina

• The brightness of the light

• The color of the iris

What is suggested after trying the experiment a few times?

• Start a new experiment

• Discuss the results with the teacher

• Switch roles with your partner

• Write a report on the findings
