KIA U4-Taste

Taste

We use our tongue for our sense of taste. We usually use it to taste food. We can taste sweet foods like candy and biter things like medicine. We can taste sour things like lemons and salty things like potato chips. Different parts of our tongue can taste different things.

If we look at the picture, we can see where we taste different kinds of food.

When we eat food, we are really using two senses at the same time. The nerves in our tongue can tell us a lot of about what the food tastes like, but we will need another sense to tell us more about the food. Can you guess what it is?

Fun Facts
Touch your tongue. Can you feel many little bumps? These bumps are called taste buds. Taste buds have very small hairs that ate connected to nerves that tell your brain what food tastes like.

Young people have around 10,000 taste buds. You get now ones every few weeks, because some of the old ones die.

When you are older, you get fewer new taste buds when the old ones die, so things sometimes start to taste different. Food that you do not like may be your favorite when you get older

Did you know.... .

That cats can not taste sweet things.

That flies taste with their paws.

KIA U4-Touch

“We had a cool class today. We learn about our sense of touch, and we felt a lot of different things. It was a game. We had to guess what we had in our hands. We felt hard things, like a bat, and soft things, like a pillow. There was a hot candle and some cold ice cubes.

Those were easy. The hard ones were the rough piece of sandpaper, the smooth glass bottle, and the slippery oil from the chicken. There was some sticky glue and a rough basketball, but the worst was the pointy pencil—that hurt!

We also learned that our skin has millions of nerves. We use them all to feel things we touch and to feel things around us like the sun and the wind. Our body is covered with skin, so we use our sense of touch from our fingers all the way to our toes.”
