Predictions, taste tests, and data—all the hallmarks of science research. Sweet or Sour is matched to young children’s tastes and talents. Work with small groups, and conduct this experiment over several days.
Families may donate foods, such as jam or jelly, raisins, a lemon or lime, dill pickles. Do children know what is sweet and sour? Are you aware of food allergies or restrictions?
On poster board, use Crayola® Washable Markers to label five columns:
What food(s) will you taste? With a Crayola® Washable Marker, list them on the chart.
Wash your hands. Spoon a bit of one food on your paper plate. Will it be sweet or sour? A friend can mark the chart for you. Taste it with a plastic spoon. Your friend marks whether it was sweet or sour.
When you and your friends have tasted all the foods, talk about what you discovered. How many foods did you test? How many people were tasters? Which food had the most accurate predictions? Which one had the fewest? Why?
Draw your impression of what a sweet or sour food tastes like using markers on white paper. Which colors express the taste? Write words to explain your ideas.
Our crayons have been rolling off the assembly line since 1903, and you can see how it’s done.
