Have students wash their hands. discuss proper methods of handling food.
Wash nectarines and peaches, scrubbing off peach fuzz, in particular, and place them in the colander to drain.
Demonstrate cutting the peaches and nectarines into wedges and then cutting them from their pits. show the different parts of the fruit: pit, skin, and flesh or meat.
While students prepare the wedges for the recipe, have them examine the parts of each fruit and make notes in their journals about the texture, size, color, shape, and smell of each part of each fruit. have students place the wedges in bowls.
Collect the bowls and place them on the demonstration table next to the blender. have students gather around the demonstration table. ask two students to put all the fruit in a large mixing bowl and mix. add the measured yogurt, orange juice, and honey
Ask students how many batches they think it will take to blend the ingredients for the smoothies. have students divide the ingredients into equal batches and place each batch separately into the blender. Blend each batch until smooth and pour into the pitchers.
When all is puréed, serve in a cup. While students drink the smoothies, discuss the differences among the fruits.
Clean up materials. if you have a school or classroom compost or worm bin, place the food scraps there.
