Note skill level. You might have four kinds, a new one every time you rotate groups. At the end of production, provide tiny cups for taste testing and vote to see which is the favorite kind. Keep a tally for graphing. Use different sized cups and spoons.
Children love spooning liquids into other containers.
Have children arrange them according to favorite taste. You may need to provide a sample of each fruit taste. Draw a picture of the order predicted and check later after taste test. Think of advertising words to sell favorite Smoothie and draw a picture or dictate to someone. Use fruits and vegetables to make prints.
