background info
What is ice cream described as in science, not just a food?
A model system
heat
both ice cream and antarctic ice go from what state to what state
solid to liquid
Name the three things that happen when antarctic ice melts
sea levels rise, ocean currents change, habitats are affected
what four ingredients are combined in step 1
milk, heavy cream, sugar, flavoring
name two of the four things ice cream contains
ice crystals, liquid water, fat droplets, or air bubbles
when ice cream melts, ice crystals turn into what
liquid water
both melt when this increases
heat/temp
why is ice cream easy for scientists to experiment with compared to glaciers?
it shows how small temp changes affect structures and explains melting over time
where do you place the mixture in step 2
a sealed bag
what two natural ice systems does ice cream behave similiarly to
glaciers and sea ice
what escapes from ice cream as it melts
air
more surface area leads to what
faster melting
ice cream melting is a small-scale example of what?
how large ice systems respond to heat
what fills the bigger bag in step 3
ice
what do scientists use ice cream to study?
how materials freeze and melt
name the three types of antarctic ice listed
glaciers, ice sheet, sea ice
antarctic ice cracks and collapses, ice cream does what
loses it shapes/melts
by studying ice creaming, scientists better understand how what affects Earth's ice
climate change
how long do you shake the bag
5-10 minutes
what is the full title of this project
freezing point science: how ice cream models melting ice in antarctica
what happened to ice creams structure as it melts
it breaks down
what are the three similarity categories listed on the bored
structure breakdown, melting process, surface area
ice cream demonstrates antarctic melting in what kind a way
a simple and visual way
how many total steps are in the recipe
4 steps
