Quick summary: Students make a ‘naked egg’ by submerging an egg in vinegar. The shell dissolves leaving a naked egg encased in its membrane.
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.
