Room 6, The puffer fish and “The Exploding Lunch Bag”

This week in our classroom, we embarked on an exciting journey into science, focusing on following instructions and sequences. Our thematic exploration led us to an intriguing experiment, “The Exploding Lunch Bag,” inspired by our ongoing theme of “The Snail and the Whale.”

As part of our scientific adventure, we delved into the fascinating realm of marine life, particularly exploring the unique characteristics of the puffer fish. We discovered this extraordinary creature’s remarkable abilities and peculiarities through discussions and a captivating video presentation.

To further enrich our learning experience, we tried to recreate the pufferfish phenomenon through an engaging experiment. Guided by careful instructions and precise sequences, our young scientists eagerly took on the challenge.

Here are the steps we followed in our experiment:

1. Put 1/2 cup of vinegar in the sandwich bag.
2. Add three teaspoons of baking soda to the tissue, then fold it up.
3. Zip the sandwich bag shut, but leave a corner open to fit the tissue full of baking soda in.
4. Slip the tissue in, quickly seal the bag, and step back.
5. Watch the bag slowly expand and explode!

Through careful execution of each step, our pupils witnessed the magic of science unfold as the lunch bag transformed before their eyes. The sense of wonder and excitement in the classroom was palpable as they observed the delightful “explosion” – a testament to the power of following instructions and understanding sequences in scientific experiments.

This hands-on experience encouraged curiosity and critical thinking and highlighted the importance of precision and attention to detail in scientific exploration.

We are proud of our pupils’ enthusiastic participation and interest throughout this experiment. Their willingness to explore, discover, and learn is truly inspiring.
