The Sense Organs, Sense of Taste, and Sense of Smell (Week 4 & 5 RTR)

These past two weeks, for our Science, we began taking a more indepth look at the 5 senses.

This is one of several books we are using this year. This book shows us how to make simple paper models of various body parts. The instructions are easy to follow and all you need is a pair of scissors, some tape, and colored pencils.



This was the first model we made from the book above. The top page has flaps cut out of it to reveal the sense organs underneath. Coyote did a nice job coloring this one.



This second model is of the mouth and tongue. We used this to learn more about the sense of taste. Road Runner colored this one. The model has a page on top with a pair of lips. You open the lips to reveal the inside of the mouth, and another flap on top of the tongue shows where different taste buds can taste bitter, sweet, sour and salty.



We had a taste test one day using lemon juice (sour), instant coffee (bitter), sugar (sweet), salt (salty), strawberry syrup (sweet), and dill pickle juice (sour).

  

Another experiment revealed how the taste of juices are hard to distiguish from each other if you do not have the sense of smell to help you out.

That's as far as we made it with the senses but, in the coming weeks, we will be learning more about the other senses of hearing, seeing, and touch.
