Students completed the sheep eye dissection. If you were absent, see the video below for details. Note: The Light and Eye Test will be next Thursday. Focus you time studying for your Math final, but you will want to start reviewing your chapter 10-12 in your textbook on light and the eye.

We reviewed far and near-sightedness from last day, click here for Your Eye Sight notes on far and near-sightedness. We also finished labeling the eye, (click here for the eye diagram and see section 12.1 in your textbook), and saw Mrs. Arcuri's demonstration on the eye dissection. Students are to review section 12.1 in their textbook on the human eye, look over their eye diagram and prepare themselves for the eye dissection on Wednesday.
HW = Review the eye because the dissection is on Wednesday. Test on Light and the Eye will be next Thursday. Today students took a few eye tests to determine if they needed to make an appointment with the optometrist to get their eyes checked. We discussed myopia (eye too long) and hyperia (eye too short), how each of them affects our vision and how we correct each condition with covex or concave lenses.

We finished the Mirror Lab, click here, and the Lenses Lab, click here. The lab on lenses investigated how light travels through straight, convex and concave lenses, see the video below for a description of what we saw in the lab today. Students started investigating the Law of Reflection (see section 11.1 in textbook) - the incident light ray (incoming ray) angle is always the same angle as the reflected light ray (outgoing ray). Students finished the Mirror Lab. Click here for the Mirror Lab.
We looked at how a light ray transmits through transparent material (clear lens) and translucent material (wax paper) and how light reflects light on a plane mirror. We also discussed the difference between a specular reflection with a plane mirror and a diffused reflection with crumpled aluminum foil. Students started investigating the Law of Reflection - the incident light ray (incoming ray) angle is always the same angle as the reflected light ray (outgoing ray). Click here for the Mirror Lab.
Today we looked at the vocabulary that describes a wave (frequency, amplitude, crest, trough, and wavelength), as well as the visible light spectrum (red, orange, yellow, green, blue, indigo, and violet). We discussed how to separate white light into the rainbow spectrum. We used prisms and spectroscopes to separate the spectrum of colours and discussed why we see different colours, why we see white and why we see black. Students completed the notes on waves and optics, click here. Many students were absent today, due to Shakespeare Festival and Leadership class to Giant's Head Elementary. Those students present watched a video on the electromagnetic spectrum, click on website to view the video https://www.youtube.com/watch?v=HPcAWNlVl-8 Students looked at very basic pinhole cameras. See the video below to make a pinhole camera. |
