Pumpkin Life Cycle STEM Activities Pumpkin Science & Engineering K-2 STEM Snack

Pumpkin life cycle learning meets a hands-on Pumpkin Gate STEM Challenge in this K–2 pumpkin science and engineering resource! Students build the stages of a pumpkin life cycle, then plan, build, test, and improve a pumpkin gate using simple materials while investigating how many pumpkins their structure can hold.

This resource includes two complete pumpkin STEM activities: a hands-on Pumpkin Life Cycle science activity and a Pumpkin Gate STEM engineering challenge. Students explore plant science, engineering design, problem solving, counting, testing, observation, and recording while working with engaging pumpkin-themed materials.

Two Complete Pumpkin STEM Activities

1. Pumpkin Life Cycle STEM Activity

Students build a hands-on model showing the stages of the pumpkin life cycle and connect each stage to how pumpkins grow.

2. Pumpkin Gate STEM Challenge

Students become engineers as they design and build a pumpkin gate, test how many mini pumpkins it can hold, record the results, and improve their design.

The two activities work together to give students both a science investigation and an engineering design challenge in one pumpkin-themed resource.

Pumpkin Gate STEM Engineering Challenge

The Pumpkin Gate STEM Challenge gives young learners an age-appropriate introduction to engineering.

Students:

• look at simple pumpkin gate design ideas
• plan how they want to build their gate
• build using paper cups and craft sticks
• place mini pumpkins on the gate
• count how many pumpkins the gate can hold
• observe what happens as more pumpkins are added
• record their results
• explain what worked
• think about how the structure could be improved
• redesign and test again

Students use the engineering design process throughout the Pumpkin Gate STEM activity.

They consider questions such as:

• How will I build my pumpkin gate?
• How can I make the gate stand?
• How many pumpkins can my gate hold?
• What happens when I add more pumpkins?
• Which design is strongest?
• How could I improve my pumpkin gate?

Students can then rebuild their gate and test a new design.

This makes the activity a great fit for pumpkin STEM centers, fall engineering challenges, STEM bins, small groups, or whole-class engineering lessons.

Pumpkin Life Cycle Science Activity

Students also build a hands-on model of the pumpkin life cycle:

seed → sprout → vine → flower → pumpkin

Students use simple hands-on materials to represent each stage, then connect the model to their science learning.

They can:

• identify the stages of the pumpkin life cycle
• put the stages in order
• build each stage
• observe how a pumpkin changes as it grows
• discuss plant science vocabulary
• draw and record their learning

The finished pumpkin-shaped life cycle model provides a memorable visual reference for young students.

This resource integrates multiple early elementary skills:

Science

• pumpkin life cycle
• plant growth
• observation
• sequencing

Engineering

• planning
• designing
• building
• testing
• improving a structure

Math

• counting pumpkins
• comparing results
• measuring
• recording data

Literacy

• drawing designs
• recording results
• explaining thinking
• reflecting on what worked

What’s Included

• Pumpkin Life Cycle STEM activity
• Pumpkin-shaped life cycle model
• Life cycle recording activity
• Pumpkin Gate STEM Challenge
• Pumpkin Gate construction mat
• Simple, double, and tall gate design ideas
• Student engineering recording sheet
• Build + test directions
• Reflection questions
• Redesign/extension challenge
• Teacher lesson plans
• K–2 standards connections
• Differentiation ideas
• Assessment suggestions

The resource includes teacher support as well as student activity pages, so the pumpkin gate engineering challenge is ready to teach rather than just a loose STEM prompt.

Materials

The Pumpkin Gate STEM activity uses simple supplies such as:

• small paper cups
• craft sticks
• mini pumpkins or pumpkin candies
• pencils
• student recording pages

That makes it easy to set up for centers, small groups, parent volunteers, or a whole-class STEM lesson.
