# 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 Willet 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.

# 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.

# 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 likeâ€”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) at the Apple Journal.

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

In this Mystery, 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.

Number of students:
 Apple Taste Test worksheet If you use different apple varieties than the ones we used, you can change the apple names in the first column of the worksheet. 1 per student 1 board per class 1 knife per class Each student needs a small piece of apple. You may need more or less apples, depending on their size. Details 1 apple per 15 students Each student needs a small piece of apple. You may need more or less apples, depending on their size.

Details 1 apple per 15 students Each student needs a small piece of apple. You may need more or less apples, depending on their size. Details 1 apple per 15 students 1 sheet per student 4 plates per class 1 toothpick per student

You need 4 different varieties of apples that have different colors, textures, and flavors. We recommend Granny Smith, Red Delicious, Golden Delicious, and Honeycrisp. But you can also use other varieties such as Gala, Fuji, or Jazz. Each student needs a small piece of each apple. This means that for a class of 30, youâ€™ll probably need two apples of each variety, but it will depend on the particular size of the apples available.

# Prepare Apples for Tasting

Before class begins (or during the video), use your paring knife and cutting board to slice each apple and remove the core. Cut each apple into small pieces so that each student can have a taste. Place all pieces for each apple variety on a plastic plate. We recommend placing the sticker from the apple variety on the rim of each plate to help you remember which apple is which.

# Graph the Apple Taste Test (Optional)

For an optional math extension, you can use sticky notes to make a bar graph of your studentsâ€™ apple preferences. Instructions can be found in our Extras section on Graphing the Apple Taste Test.
