Present the whole plant as well as its seeds. Using magnifying glasses, have students observe, touch, and record their individual observations. As a class project, make whole wheat bread.
Students can work in small groups of two or three, and then make their own loaves of bread.
Take a cup of oatmeal or corn meal. Slice a potato in half and place inside your cup of meal. Meal worms will eventually become evident. Have students observe and record their observations. They can also graph individual days and the results.
