In addition to looking pretty neat with all those loops and whirls, your fingertips are great at multitasking. The skin on them has a ton of receptors that help us to gather a lot of information about our environment such as texture, movement, pressure, and temperature.
This experiment will test your ability to determine textures by using touch receptors. You will use shoeboxes with holes cut into them to make texture boxes. Each box will have a textured surface that you can feel, but not see. Through the receptors in your fingers, you will determine whether the surface is rough, waxy, soft, or smooth.

Absolutely! Think of these experiments as just the starting point… you take it from here and see how far and awesome you can make the project!
Do you think that we have to use those same materials in the boxes, or could we use other things such as Velcro (a lot of it), wood, or even leave the box empty?
Oh my gosh! I am so sorry about that! My programmer was working on editing the videos, and it looks like something awful happened there. I’ll get right on this and fix it. Again, my apologies for the trouble. This was supposed to be seamless and not noticed by our users!!
Hi Aurora,
Why aren’t we seeing the videos, but only the same “Biology Essentials-037, Cell communication on all of these lessons?
Thank you!
Lisa
