# Extra Activity: How Many Seeds?

Cut an apple in half horizontally, and you'll see five seed compartments arranged in a star. How many seeds are in each compartment?

Your students will find out in this activity from the Willett Garden of Learning. Students predict the number of seed they will find in each apple, then work in groups to count seeds and compare the results.

Apple growers use seed counting to find out how successful the bees in their orchard have been. Empty seed compartments mean that some of the apple flower's eggs were not pollinated. Some farmers think that apples with more seeds are bigger or juicier. Ask your students what they think, after observing their apples and counting the seeds. (You'll find more information about apple seed counting here.)

# Math Extension: # Graphing the Apple Taste Test

Use sticky notes to make a bar graph showing students' apple preference. Draw a horizontal axis and a vertical axis on a large piece of paper. On the horizontal axis, make four columns, each the width of a sticky note. At the bottom of each column, write the name of an apple variety.

Give each student a sticky note and have them place it neatly in the column of their favorite apple. The notes will form the bar of the graph.

For more on graphing with sticky notes, visit Schoolhouse Diva.

# Language Arts Extension: # Once Upon an Apple

Apples often play an important role in fairy tales, myths, and folklore. In a class discussion, ask students if they know any stories in which apples are important. Possible examples are Snow White and William Tell. You'll find other examples from around the world at The Fairy Tale Cupboard.

Ask students to write a story that begins: "Once upon a time, I found a magic apple in my lunchbox." Encourage them to describe what the apple tasted like—and what happened when they ate it.

# Web Resource: Apple Varieties

If your students are intrigued by the Apple Taste Test, there are many other apple varieties to sample. You'll find them listed by name (with a description of each) here.

If you want to find a apple orchard that your class could visit, check Orange Pippin for one near you.

Activity Prep

Print Prep

In this lesson, students learn how the food we eat is a result of selection. In the activity, Apple Taste Test, students taste four different varieties of apples to learn about the traits (color, texture, and flavor) of apples that humans have artificially selected to encourage.

Preview activity

Students at home
If students have apples at home, ask them to take a close look at the core. Alternatively, you can provide them with photos. Ask students to draw the apple core and write down questions about what they notice inside the apple. Can they find the seeds?
Students at school
Ask each student to take a close look at the core of an apple. Ask them to draw the apple core and write down questions about what they notice inside the apple. Can they find the seeds?
