Primary School Supply Tower Height Test STEM Challenge

Challenge primary learners to explore structure, balance, and stability with this School Supply Tower STEM Challenge. Learners build the tallest free-standing tower possible using school supplies, measure the height, improve one part of the design, and compare results. This practical KS1 STEM activity combines hands-on engineering, testing, and measurement.
WHAT’S INCLUDED
• 3-page STEM activity set: Cover Page, Instructions Page, Activity Page
• Built-in table or recording boxes for comparing results
• Sketch, notes, or observation space for student thinking
• Clear, step-by-step directions for classroom use
• ZIP file with printable PDF resources
SKILLS DEVELOPED
• Engineering design process
• Problem-solving and critical thinking
• Testing and improving designs
• Recording and comparing results
• Structure and stability STEM learning
HOW IT WORKS
Learners use 10 pencils, 4 sticky notes, 2 index cards, and tape to construct a free-standing tower. They test whether it stands independently, measure and record the tower height, and then modify one part of the design before carrying out a second test. Learners compare both height measurements and consider how the design change affected the outcome.
The recording structure provides space for planning, sketches, building notes, and height measurements, helping learners make clear connections between design choices and results. The activity encourages learners to investigate how stability, shape, and support influence performance.
The challenge naturally scales from simple building and testing to deeper investigation, comparison, and explanation of results.
