Warning: Kool-Aid can stain clothes, tables, and floors. Let your children experience the sense of feel with slime! It is simple to make simply add glue with cornstarch and stir well. You may have to add a bit of one of the ingredient to get the right consistency (to sticky add more cornstarch) but the children will love it. To keep it from getting to sticky store it in the refrigerator.

Alternatively you can make less sticky slime with cornstarch and water (add more cornstarch if its too thin, more water if its too thick)

A Third Alternative is to make it with one cup of water with one cup of white glue and two tablespoons of liquid tempera paint take an ice cube tray and fill it with object that have feel different (some example might be sandpaper, slime, net, fur, dough, felt, silk, cork, grass, bark, leaves, sponge) Let your children feel the different objects and talk about the differences with them. Put different scents (peppermint, garlic, strawberry, lemon, vanilla, etc) on several cotton balls and place then in separate plastic containers with tops. Have children guess what they are.
Make a volcano and it will cover all of the senses. Simply build a volcano with either clay or paper-mâché. Remember to put a small cup at the top of the volcano. Add food coloring to the vinegar to make it red or orange. Put baking soda in the cup and slowly drop the vinegar as it erupts your children will be able to see the explosion, smell the vinegar, hear the reaction of the baking soda and vinegar, and if you wish touch and taste the mixture. Bring two foods that look similar but taste very different (orange and lemon, sugar and salt, yogurt and sour cream, etc.) Put them in plates next to each other. Let your children use their 5 senses to try to determine which is which. Asked the children to describe how the substances smell, feel, look, sound (as you gently shake the plate) and finally taste. Use a small amount of various spices and let your childreen smell them. It is a great way for them to smell a lot of unique smells. Trace your children on a large piece of paper. Have them either write, draw, or place stickers on the different places where their senses are (for instance draw a flour on your nose, a violin on your ear, etc.) Put fresh coffee grounds in sensory table with scoopes and spoons - great for experiencing smell Everything Preschool >> Themes  >> Five Senses >> Science
