Back-to-School STEM challenges are a great way to build community, establish procedures, and get to know how your kids tick!
Plus, this is a great intro to forces and interactions and Newton’s three laws of motion, which are part of 3rd, 5th grade and middle school NGSS standards! (3PS2-1, 5PS2-1, MS-PS2-1, and MS-PS2-2)
Of course, this challenge is also great for any time in the fall when learning about apples and Johnny Appleseed!

The basic premise:
Individually or in partners/groups, students will design and build a cantilever to suspend an apple as far away from a desk’s edge as possible.
Multiple iterations are recommended to get the most student benefit, but this can also be treated as a one-off activity.
This challenge is available in the Back-to-School 5-in-1 STEM Challenge BUNDLE at a savings of 40% off the cost of buying each challenge separately. What a bargain! ☺
This resource is also available in the STEM CHALLENGE YEAR-ROUND MEGA-BUNDLE at an even greater discount!
Benefits of this STEM Design Challenge:
- Focus on critical thinking, problem solving, and application of learning
- High levels of student engagement
- The potential to hit upon all NGSS ETS standards depending on the depth and number of iterations you choose to implement in your classroom (modifications included)
- Highly flexible and differentiated for materials, timing, grade levels, and rigor.
Each design iteration should be planned for at least ~ 60 min. if you are including data gathering and analysis rather than just building for fun. If you add extension activities, you will need to adjust timing accordingly. I recommend working on STEM Design Challenges in multiple iterations to get the full value.
Materials you’ll need to do the activity are easily modified.
Sample/suggested materials for each student or group:
– Small apple (1)
• Use very small apples. For younger students, you may prefer to not use the apple at all
– Unsharpened pencils (5 – 10)
– Rubber bands (5 – 10)
– Pocket folder with prongs (1)
• File folder or pocket folder without prongs may be substituted
– Tape (one roll of masking tape)
– String or yarn (36 – 48 in.)
– Medium and/or large binders clips (2 - 4)
– Paper lunch bag (1)
– Ruler or measuring tape
– Desk or table
• Devices can also be built from counters, but a desk or table offers more options to create tie-downs and ways to secure the devices.
– Design analysis handouts (included)
• Craft sticks
• Pipe cleaners
• Paper clips
• Single hole punch
• An extra ruler with which to build
NGSS aligned standards, Grades 2 – 8
