Bubble Geysers

[Image appears of text on a black screen: The following video made by Anula Primary School was prepared for Questacon’s Science in First Languages Project as part of the International Year of Indigenous Languages 2019]

[Image changes to show a close view of five students on a basketball court with a basketball, and then the students shout and raise their hands and the basketball in the air]

Producer:  And again! 

Group:  Anula!

[Music plays and the image changes to show text on the screen: Science In First Language]

[Images flash through of various people and children in various traditional activities, dances, talking, experiments, and school children playing basketball]

[Image changes to show text: Science in First Language]

[Image changes to show a medium view of the five students in a line behind a table with two soft drinks, and then the image pans in to show each student saying their name, and text appears: Nhamirri!, Hello!]

Producer:  Action. 

Lashon:  It’s Lashon.

Amber:  Amber.

Kiara: Kiara.

Tinisha: Tanisha.

Joshua: Joshua.

[Image changes to show the group of children all talking together, and then the image changes to show a teacher holding a sign in a classroom,]

Group: Nhamirri! We are all from different parts of the NT. 

[Image changes to show the five students lined up by the table with soft drinks and mentos talking to the camera, and text appears: Kunwinjku, (Yolngu Matha) Let’s do some science with soft drinks, Soft drinks contain sugar, flavourings and preservatives]

Today we’ll be talking with you in Yolngu Matha and Kunwinjku.

[Camera zooms out a little on the group talking to the camera, and then the camera zooms in on a bottle of soft drink]

Group: (In Yolngu Matha) Let’s do some science with soft drinks. 

[Image changes to show a medium view of the five students talking to the camera and holding up the bottles of soft drink]

Soft drinks contain sugar, flavourings and preservatives.

Producer: Ready, go!

[Image shows the five students listening and then talking to the camera again]

Group: Action!

[Image shows the five children listening and then laughing]

Producer: No, no. Read this.

[Image shows the five students beside the table with soft drink and mentos talking to the camera, and the camera zooms in on the soft drink bottle, and text appears: Their fizziness comes from, Carbon Dioxide (CO2), which is dissolved, in the soft drink]

Group:  Oh! (In Yolngu Matha) Their fizziness comes from Carbon Dioxide, CO2, which is                       dissolved in the drink.

[Images move though to show the students laughing and shaking the soft drinks, a close view of a student opening a lid, and the students jumping back from the frothing bottle, and text appears: Hey! Shaking the drink, the gas will come out as bubbles!]

Lashon: Hey, you’re shaking the drink, the gas will come out as bubbles. (In Kunwinjku)

[Image shows Lashon talking to the camera, while the other students listen, and text appears: (Kunwinjku) All the gas has gone, escaped as bubbles

All  the gas has gone, escaped as bubbles.

[Images move through to show students shaking, opening bottles and then jumping away from the frothing bottles, holding bottles as they talk to the camera, and writing at a table, and text appears: (Yolngu Matha) The bubbles form in the little dents, in the side walls of the bottle]

Group: (In Yolngu Matha) The bubbles form in the little dents in the side walls of the                              bottle. 

[Images changes to show, the students holding bottles while talking to the camera, and text appears: The science word for these dents, is “NUCLEATION SITES”]

The science word for these dents is Nucleation Sites. 

[Image moves through to show views of the students talking to the camera, Amber opening a bottle which froths over, the frothing bottle, and liquid running off the table, and text appears: When you open the bottle, all the bubbles rise quickly to the top, pushing the liquid out of the way]

When you open the bottle all the bubbles rise quickly to the top, pushing the liquid out of the way.              

Amber:  And voila!

[Images move through to show the students listening to Lashon talking as Amber shakes a bottle, a close view of Lashon and Amber, and then the bottle, and text appears: (Kunwinjku) But imagine if we could make even more bubbles, What do you think would happen?]

Lashon: (In Kunwinjku) But imagine if we could make even more bubbles quickly. What do you think would happen?

[Image changes to show the students talking to the camera together] 

Group: Let’s add Mentos to the drink and see what happens. 

[Images move through to show a close view of paper being rolled into a tube and being inserted into an open bottle, and then a mentos being put down the paper tube, and text appears: (Yolngu Matha) We are rolling up paper to make a delivery tube, to feed in the Mentos, and see if they make more bubbles]

(In Yolngu Matha) We are  rolling up paper to make a delivery tube to feed in the Mentos and see if they make more bubbles.

[Images move through to show students pulling out the tube as the Mentos falls into the soft drink, the students jumping back as the drink froths over the table and onto the ground, and text appears: What do you think is happening?]                   

Oh, oh! What do you think is happening?

[Image changes to show the students examining the frothy liquid from the Mentos from various angles, and then the image shows the liquid pouring off the table]

[Camera pans up to show Kiara talking to the camera as the other students looking at the bottle]

Kiara: Where’s the mints gone though?

[Image shows Joshua talking and lifting the bottle while the other students look]

Joshua: They went to the bottom. Can you not see them, look?

[Image shows Kiara talking to the camera as she looks at the bottle]

Kiara: Oh, they have.

[Images moves through to show a close view of hands holding Mentos, the students taking Mentos out of the packets, and then hands holding Mentos next to the bottles, and text appears: (Yolngu Matha) Mentos are made by spraying layers of sugar]

Group: (In Yolngu Matha) Mentos are made by spraying layers of sugar. 

[Images move through to show Kiara and Tinisha holding and inspecting the Mentos, Kiara’s face, and the five students talking and then eating Mentos and laughing, and text appears: This makes thousands of dents in the Mentos]

This makes thousands of dents in the Mentos. It’s important in science not to eat the                               materials. 

[Laughter can be heard, and images move though to show students talking as a group, reading a teacher held sign, Tinisha touching the sign, and hands dropping Mentos into a bottle, and text appears: (Yolngu Matha) The mints in the soft drink, mean thousands and thousands of nucleation sites, for bubbles to form]

Group: (In Yolngu Matha) The mints in the soft drink mean thousands and thousands of           nucleation sites for bubbles to form.

[Images move through to show a lid being opened, and then the students talking to the camera as Lashon drops a Mentos via a paper tube into a bottle, and text appears: (Kunwinjku) Just watch how many bubbles form at once]

Lashon: (In Kunwinjku) Just watch how many bubbles form at once.

[Image shows the students jumping back as the drink froths out over the table] 

Group: All the bubbles come and quickly and whoosh. Ohhhh! 

[Images move though to show the students talking to the camera, fingers pointing to an open bottle, and then the students talking to camera and giving the thumbs up symbol]

All the CO2 is gone at once. Science!

[Music plays and the image changes to show a black screen with the the Questacon and Australian Government Department of Industry Innovation and Science logos, and text appears: Starring - Lashon Bonson, Amber Garrawurra, Kiara Peters, Tinisha Dhamarrandi, Joshua Peters, Producer, Will Tinapple]

[Image shows new text: Thanks to Anula Primary School, Di Rollo, Kerry Hudson, Formation Studios]

[Images flick though to show Amber and the others pouring oil into a soft drink, the students each with their bottles ready to drop a Mentos in, erupting bottles, and a close view of bubbles in bottles]

Group: If you liked that experiment we could teach you how to make lava lamps next                              time.

[Images move through to show a close view of Amber talking and a bottle with bubbles can be seen in the foreground, Kiara talking to the camera, and the students waving at the camera]

Kiara: How come the bubbles down here, how come they go up instead of stay down                                there?

Group: (Unidentified).
