- original worksheet
- card stock (I glued the worksheet pieces onto cardstock so that it wasn't flimsy)
- variety of textured paper (e.g. sandpaper, foam, ribbed cardboard etc.)
- puffy paint
- braille label paper (http://www.americanthermoform.com/product/braille-labeling-materials-bra...)
- Cut out all of the "circles" and glue them onto cardstock paper.
- Trace the map of the Earth with puffy paint and label it in braille.
- Create a seperate Key page that shows the layers of the Earth and the textured paper that correlates with each layer.
- Add a different textured paper for each layer of the Earth.
- The textured paper could have been cut out ahead of time but not attached. The student could attach the textured paper himself while the other kids color their paper.
- Instead of textured paper, the lines that separate the layers could be traced in puffy paint (to create a raised line) and the students could color in the layers themselves. They could place a different screen underneath the worksheet, so that a different raised pattern will show through each layer.
Editor's Note: There are other examples of activities to make the layers of the Earth accessible to students who are blind or deafblind on the Accessible Science site:
