Tactile Bulletin Board: Cells

Animal cell
New Year and new units! We jumped into life science to start the new term. One of the curricular standards for fifth grade is to be able to label the parts of an animal cell and a plant cell.
 
After reviewing several visual diagrams and the definitions of the components, I had two sighted peers rummage through my junk box of craft supplies and dollar store treasures. They were tasked with finding objects that "felt like they should" based on their appearance. The cells were then constructed on vinyl placemats (cytoplasm) with identical items representing the same parts on both cells. For the plant cell, the cytoplasm was cut to fit within the cell wall (a turn-in basket) and also includes a plastic stencil of a flower to represent chloroplasts.

For interactive practice, pushpins were used on label cards (click to download) as well as the cell parts to attach using rubber bands.

There are QR codes (click to download the QR codes) posted linking to a Bill Nye episode on Cells, as well as the Cell Rap, and an explanation of photosynthesis for the student to scan in and listen for more information.
 
Braille booklets hang below to define the parts of each cell, explain the purpose of each part, and offer a tactile diagram (PIAF). For enrichment, there is a booklet containing a brief overview of course requirements and job opportunities in cellular and molecular biology. (Why is it important to study these tiny things that can hardly be seen under high magnification?) Click to download a booklet of jokes.

It was a lot of fun to have the outlook of peers on this project. Not only did they have ownership in the construction of the cells, but they had fun doing it!
