Team 4 - Science Exploration Day! Dry Ice

Today, we had a day where we busted myths! We had a lot of fun experimenting to learn about the scientific method and changes between solids, liquids, and gases.

We completed a 3-way rotation. In these photos, we are exploring sublimation (changing from a solid to a gas). We used dry ice to show this change in state through a number of experiments.

SAFETY

Did you know that dry ice is a solid and has a temperature of -78.5 degrees celsius? That is 78.5 degrees colder than frozen water (ice)!
















It is so cold that whoever handles the dry ice has to wear gloves to protect their hands from the cold!

DETERGENT BUBBLE



In these first 3 photos, we showed a build up of gas as the dry ice went through sublimation by created a detergent bubble over the bucket.

DRY ICE AND WARM WATER



Here, we added dry ice to water to show the release of a gas during sublimation.

BLOWING UP A BALLOON





In these photos, we compared a balloon which had been blown up by using our breath (left), and a balloon which had been blown up by the gas created using dry ice (right). The balloon on the right was much heavier so it hit the ground first when dropped. You can also see that the balloon on the left is see-through where as the one on the right is not.

EXPLORING THE RESULT OF DRY ICE, WARM WATER, AND DETERGENT
 


We then explored the result of mixing detergent, warm water and dry ice. It created a foam made up of lots of bubbles which turned into a gas when popped!

STUDENT LEARNING

We finished by creating a blog post showing our learning. Check out Ayla's learning here!






Today we were doing rotations we had 3 rotation this is the last rotation I came too. In this rotation we were using dried ice and applying it to warm water.

  1. Morena Room 9,
    My name is Tania and I am one of the Manaiakalani Outreach Facilitators. I live in Whangarei and work with lots of teachers and students who like you, are using blogs to share their learning. I am so pleased that you have joined our Tuhi Mai Tuhi Atu programme this term and will be working really hard on leaving quality blog comments on other class blogs. I hope you enjoy seeing what is happening in other classes and get ideas from them too. Ch, ch, ch, ch changes sounds like you are going to have a FUN term! How lucky to get a chance to be myth busters and try out some experiments! Keep up the great sharing. I will make sure I check out your class blog on a regular basis and hope to look at some of your individual blogs and leave comments too. Let me know if there is anything I can help you with.

  4. Hi Ben,
    The ice looks freezing and adding the dry ice looked really cool! Next time you could write how you did it.

    1. Hello Eva
      Thank you for commenting on our blog. It did take us a long time to clean up because there was water and soapy bubbles everywhere.

  9. Hi Eva
    Thanks for commenting on our blog.
    It probably did take a bit longer to clean up the mess because there was soppy bubbles everywhere and it was very cool doing science.
