Activity Introduction

Quick summary: In this activity students plant seeds in a plastic bag and watch them grow.

These Snappy Science resources have been created to boost science education in primary schools across Australia. Each lesson is designed to support teachers with the scientific knowledge, ideas and resources to stimulate a sense of wonder and curiosity in their students. Many of the big issues that Australian society will face in the future are around technology, energy, resources and climate change. All of these require students to engage with science – but most of all to enjoy science!

Science at Home: These Snappy Science resources can also be used to engage families in fun science and learning for life. You can download a student friendly version of this activity here and you can also check out the Snappy Science Digital Library.

General capabilities: Critical and creative thinking.

Teacher Worksheet

Brief summary:

In this activity students plant seeds in a plastic bag and watch them grow.

Students can use the Predict, Observe, Explain table on the Student Worksheet to describe and reflect upon this experiment.

You will need:

  • Paper towel
  • Pencil
  • 3 different seeds, for example corn, beans, radish
  • Stapler
  • Ziplock plastic bag
  • Water

What to do:

Step 1. Take a piece of paper towel and fold it in half. Using a sharp pencil, make three small holes along the fold of the towel, equally spaced apart.

Step 2. Place the seeds over the top of the holes.

Step 3. Fold the paper towel back, stapling up the side to make a pouch.

Step 4. Place the paper towel into a ziplock bag and pour a small amount of water into the ziplock bag (the paper towel should end up damp). Leave the bag open.

Step 5. Hang your experiment on the wall in a bright location, but not in direct sunlight.

Step 6. Watch over the coming weeks as the seeds germinate and begin to grow.
