Inspired by the scientific explanation of the Giant's Causeway, we have been thinking about Volcanoes. Over the course of a few days, we have watched volcanoes, observed how they move, their colors, and more. Today, we used a scientific experiment to create our very own volcanic eruption.
One of the more famous (or most quoted) quotes from Loris Malaguzzi (Reggio Emilia) is, "Nothing without Joy." In fact, it hangs on my wall next to my desk where I sit for each of our calls. Today was certainly one of the most joyful days. The joy and excitement was palpable, and quite the family affair. We had whole families, older siblings, caregivers, and there seemed to be joy radiating from each face. It seems that a little bit of "simple science" brings out the curiosity, playfulness, and excitement in all of us.
“This is the most epic thing we’ve ever done!”
We began our call by revisiting some of the live and pre-recorded footage of the volcanoes in Iceland.
As children explore their world, from birth, they are constantly engaging in the scientific method. Simply broken down it includes: Making an observation, asking questions and creating hypotheses, testing them out with an experiment, analyzing your data, and reporting conclusions.
After a few days of observations, we were ready to create some hypotheses about if and how our experiment would work.
When we’re doing an experiment, we don’t always know what’s going to happen. Do we already know what’s going to happen with this experiment? - Elyse
“Yes.” - Lane
“No.” - Giacomo
“Yes.” - Rose
“Hmm I guess that I know.” - Saul
Do we have any hypotheses about what might happen? What will happen when we mix all of the ingredients together? - Elyse
“It’s going to erupt.” - Lane
“It’s going to explode!” - Saul
Which ingredient is going to make it erupt? - Elyse
“The baking soda.” - Lane
“Yeah, the baking soda. “The baking soda makes it erupt.” - Giacomo
Do you think it’s going to be a big eruption or just a small eruption? - Elyse
“A big one.” - Giacomo
“Small.” - Lane
“No, Elyse. I saw quite little volcanoes. I couldn’t see the big ones. I just saw the little volcanoes.” - Saul
The steps/ingredients of our experiment
“It’s an eruption!” - Saul, 3.8 years
“It’s erupting!!” - Lane, 5.5 years
[Rose was squealing with excitement]
“Pour all of it [vinegar]!” - Rose, 8 years
Rose and Giacomo’s is a slow eruption. - Elyse
“Ours is a fast one.” - Lane, 5.5 years
“Look! I’m taking cups of it. Yeah! I’m spooning it out. Look it’s so cool.” - Saul, 3.8 years
Analyzing and discussing conclusions
As we wrapped up our experiment(s), we took a minute to revisit the footage of the active, Icelandic, volcanoes.
I'm going to share the screen. What do you think? Was it like this volcano? - Elyse
“Yeah.” - Saul, 3.8 years
“No because it didn’t have a little river.” - Lane, 5.5 years
“It didn’t take a certain path down.” - Will, 7 years
“It went all over the tray, but not too far. I learned something about volcanoes. When lava is underground it’s called magma. When it’s above ground it’s called lava.” - Lane
“Guys, can we make another lava?” - Saul
At the beginning, you thought the baking soda would make it erupt. Was that true? - Elyse
“I thought baking soda would make it erupt, but now vinegar would make it erupt.” - Lane, 5.5 years
“We made it explode.” - Saul, 3.8 years
When we added water, it didn’t erupt. We added dish soap, and it didn’t erupt. Once we added the vinegar, it erupted. So, it’s the baking soda and the vinegar when they come together. - Elyse
I’m so glad that you guys like this experiment! - Elyse
“I love it. I want to keep it forever. This is the most epic thing we’ve ever done!” - Lane, 5.5 years
“It’s science!” - Will, 7 years
