How to Use This Unit – Vision for TpT
There is no charge for the PPT's in this bundled unit. The only charge is for the assignments. The PPT's are also free under separate cover in this store:)
I usually begin this unit with a few videos such as “Eyewitness – Sight” and some eye anatomy videos from YouTube (Crash Course has a few really good ones). We talk about our vision in general as a class – who wears glasses, contacts, is anyone color blind? Most students remember from elementary school that the image is projected upside down on the retina, but they don’t know why or how it is ‘righted’ once the image is processed in the occipital lobe. With the exception of the basics, most students don’t know eye anatomy. This unit covers it all!
I spend a lot of time on vision in the classroom. What I sell in my store is supplemented with lots of other activities that are not mine, so I cannot list them here. So this is a great supplement to what you already have OR a great way to begin and then add to the unit. Happy Teaching!
1. “The Story Behind the Human Eye”. This includes paragraphs of information with questions to be answered after reading the material. A key is included. This assignment will take approximately 30 minutes to complete. This is a great introductory assignment. It is an electronic document to be used on a laptop/computer and submitted through a drop box but can also be printed out for a paper copy with little to no modification of the original document. *See below.
At some point I show the Retinal Photography PPT, explaining what an optometrist sees when they look inside your eyes during an eye exam. This PPT also shows retinal photographs of some eye diseases as well.
I also show the Color Blind Cards PPT. Every once in a while we come across a color-blind student (usually a boy – he more than likely inherited this sex-linked trait from his mother; this starts a whole new conversation about genetics).
2. “Anatomy of the Eye” involves using a website to learn all the structures and functions of the eye. It is an electronic document to be used on a laptop/computer and submitted through a drop box but can also be printed out for a paper copy with little to no modification of the original document. *See below.
3. “Eye Know That!” This assignment also uses a website to learn the structures and functions of the eye. This is a paper assignment, just print.
4. “Optical Illusions PPTx”. This is loads of fun and will take approximately 30-40 minutes to complete. The optical illusions are all interactive for the students to participate in.
5. After we talk about optical illusions, I show the “3D Chalk Art PPTx”. This is a compilation of 3D sidewalk art created by various artists around the world. The students are amazed at what can be drawn to “look” 3D. Several slides (there are about 36 of them) show how these works of art have to be viewed at the proper angle in order for them to become 3D. There is no assignment with this – only viewing enjoyment.
6. Last but not least, we talk about inkblots. In the “Inkblots” PPTx, there are 10 common inkblots, some of them in color (which isn’t often used in inkblots). The students must take out a piece of paper, write the numbers 1-10 on it, and write down how they perceive each inkblot. Then we compare results at the end. After that, we make our own inkblots by using some watered down black tempera paint and some plain white paper. Fold the paper in half, open it up again, and dribble the black paint on one side of the paper ONLY. Then fold the paper at the crease again, creating an inkblot when opened up. They can then interpret their own inkblots, and their classmates’ as well.
* I give a lot of electronic assignments to be completed by the student on a laptop then submitted in a drop box such as Black Board, Schoology or School Space. In order to do this effectively, I create Word assignments without using lines for answers. Trying to type an answer on a line just makes the line shift on the document. So instead of a line, I use two red asterisks (this is so fast and easy to create). The students place their cursor between the two red asterisks and begin typing their answers (or their name, date, etc., wherever they need to type information). This makes it easy for them to see that they’ve answered the question (in red) and I can easily grade the assignment electronically (I’m always looking for the red answers!). Any of these assignments can easily be made into a printed paper copy with little to no modification of the original document whatsoever. Just print! Gotta love Word!
