Transparent, Translucent and Opaque

comparing degrees of transparency of materials

Transparent, Translucent and Opaque: This is a poster I made when I was teaching about properties of light. It shows a solid object (the yellow string of yarn) being placed behind different types of paper (transparent, translucent, and opaque). I cut out rectangular samples from different paper sources: clear cellophane packaging for transparent paper, waxed paper for translucent paper, and colored card stock paper for opaque paper. 

I love using simple materials to do experiments. Below is a quick activity that students can do to compare the degree of transparency among different types of paper. (As an Amazon affiliate, I may earn a commission for purchases using my links. Learn more.)  

Use three similar flashlights, and rubber-bands to secure each sheet of paper over the face of the flashlight. Turn of the classroom lights to get the room dark enough, then flick on the flash lights simultaneously to shine at the wall. Your students can try this with other types of paper like tissue papertransparency paper, recycled paper, etc, and sort these types of paper on in a table or sort them in a continuum that goes from transparent to opaque. 

I have worksheets like that and other posters to go along with them here in a Properties of light unit. It is available at my TpT collection.

This download has worksheets, posters and activities for sorting pictures of different objects into the 3 groups: Transparent, Translucent and Opaque. Definition posters are also included for light terms such as reflection, refraction, lens, concave, convex, and prism. 

This is the digital Transparent, Translucent and Opaque Sorting Activities for Boom Learning. Students can be assigned this activity to be done on tablets or laptops. It is available here at my TpT Boom collection but it is hosted on the Boom Learning platform.

Also, there is now a States of Matter Sorting Activity for Google Classroom which is just like the Boom version.

Have fun! More ideas will be added soon.

About Me

My photo
As a Caribbean primary school teacher, I share my unique classroom with the world through this blog. Readers step into my class through the pictures, articles and classroom samples of games and lessons used in my class. I have been teaching since 2005 at the std. 4 primary level in Trinidad and Tobago. I am particularly interested in sharing my own personal lesson plans, tests and activities. Teachers need to share ideas and support each other because in doing so, we help to educate our students and develop ourselves as teachers. Technology is ever evolving and we as teachers should get on board with it, collaborate and keep up to date with this new age that we live in. Our students belong to this technological era and we must embrace opportunities to learn from each other in this global community. I also love to express my creativity in the classroom. I am a bit of a craftster . So I'm always cutting, gluing or making something... a game, a chart, a learning center, etc. So, teachers and parents, feel free to stop by and see what's new at Nyla's Crafty Teaching!
