One of my favorite things to do in the STEM classroom is to use common everyday items in new ways to create fun STEM challenges for students. During the back to school season, I like to work with materials that are fall-themed, like apples. In this apple tower STEM challenge students will compete to see who can create the tallest and sturdiest tower using only apple pieces and toothpicks! This is one of our favorite no prep STEM challenges.

If you want to challenge your students to start thinking with design and engineering in mind, starting early is a great idea! Apples are a fun addition to a traditional building challenge that make it fun for back to school.
Keep reading to grab the apple tower STEM challenge lesson plan and learn what you need to set up your own engineering challenge in the classroom!
Apple Tower STEM Challenge Lesson Plan
This creative STEM challenge is the perfect simple STEM challenge to get children thinking like engineers.
First, set up the conditions for the STEM challenge. Tell the students that they will divide into groups of 4-5 students and compete to see which group can create the tallest apple tower using the given supplies.
Make sure to discuss the basics of engineering and what makes a good design. What elements are needed to keep a tall structure from falling?

What are some of the techniques that structural engineers use to keep tall buildings standing, even in heavy winds?
I love open-ended STEM challenges like these because it not only helps kids discover design solutions, but it also sets the tone for creative, yet logically thought out thinking from the first few days of school.
What Do You Need to Do the Apple Tower STEM Challenge?
You will need 2 apples for each group of students, which you can purchase from a local grocery store. You will also need:

- Toothpicks (I like giving each group of students one of these small toothpick containers of 250, so that each group has the same amount)
- Tape measure
- Pencils and paper for each group
- Plastic baggies to store apples
- Sprite (to keep the apples from browning as quickly)
- STEM Journal for each group to jot down design ideas and record what went right or wrong with their design

Additional STEM Challenges for This Lesson
There are a lot of things you can test using apples and toothpicks. For example, you can test the stability of each design by putting it on a paper plate and shaking gently to represent an earthquake.
Use a box fan to blow air at the towers and see if they get damaged to represent severe weather.
Ask your students for additional ideas on what other tests they could conduct on their apple towers.

When setting up a STEM challenge give children a specific direction or handicap, but let them use their creativity to build their towers however they think best. This will help the children retain the information they learned during the discussion portion of the lesson.

How to Teach the Apple Tower STEM Challenge
Using apples is a fun way to turn engineering on its head! In this apple tower STEM challenge students will learn how to construct towers using toothpicks and apple pieces and even whole apples!
Materials
- Apples (2 per group)
- Toothpicks (1 box per group)
- Plastic baggies (1 per group)
- Paper and pencils for each group
Tools
- Measuring Tape
- Knife
Instructions
- Before bringing the apples to the classroom, cut the apples into 1-inch cubes. You can drop the apples into Sprite before placing into plastic baggies to keep them from browning as fast. Give each student group about two apples worth of pieces.
- Make sure every bag has the same number of apple pieces.
- Challenge the students to think about different types of designs and structures that they have seen.
- Explain that each group will use engineering skills to try to build the tallest tower with the apple pieces that they have.
- Give a bag of apples and a box of toothpicks to each group in the classroom.
- Set a timer for 10 minutes and allow the kids to brainstorm construction ideas.
- Set a 20 minute timer to allow the students time to build their structures.
- Use a measuring tape to see which group had the tallest tower.
- Discuss the strengthens and weaknesses of each design. Just because a tower was the tallest, did that also make it the strongest?
