Hmk: Read pages 551-553 and answer questions #1-6 on page 553
Today we looked at convex and concave lenses. We used the rayboxes to see how light behaves when it goes through these 2 different lenses. We also discovered the imaging rules for the Convex lens.

Today we used rulers and the imaging rules from yesterday to locate and describe images in a concave mirror. Today we discovered how light rays behave when they hit a concave mirror. We did this by using the rayboxes and finding the focus point.
Quiz tomorrow: study properties of light, electromagnetic spectrum, sources of light, ray diagrams, law of reflection and images in plane mirrors. (including SALT characteristics) Today we took up the answers from the lab activity yesterday.
Note- Laws of Reflection Read pages 479-481, ques. #1-6 Read pages 484-487. ques. #1-5 Note on light as an electromagnetic wave.
Read pages 463-469 and answer questions #1-9 on pg. 469 Draw the electromagnetic spectrum (p. 465) Try this Activity! P.467- using the ray boxes and prisms, split white light into the continuous sequence of colours Today we took a note on the 8 sources of light and examples.

Demo with laser... Optical Illusions What do you know already? p.467 #1-7 in pairs Today we talked about neutralization reactions- acids and bases neutralize each other!
Demo... we added Li, Na and K to water to produce a base and hydrogen gas. We used the pheno indicator to test that it was a base and then added HCl to neutralize it! Hmk: Read pages 278-281 and answer questions #1,4,5,9,10 |
