Little Scientists – Ice Cream in a Bag



One of our regular monthly events at momstown Guelph is Little Scientists.
This month’s theme is The Desert, which is fitting since this week has felt like living in the desert. 

 



Our experiment this month was Ice Cream in a Bag. 
 
We started out by putting 1 cup of half and half cream, 2 tbsp of sugar and ½ tsp of vanilla in a ziplock bag. 
 
We then filled another ziplock bag ½ full of ice and added ½ cup of sea salt (rock salt or kosher salt also work, table salt can work, but the bigger the granuals the better.) 
 
We added salt to the ice to slow the melting rate and increase the freezing rate. 
 
The smaller ziplock bag was added to the large one and the shaking began.  The kids let the adults shake, but they ate the ice cream.  Shaking the bags turned the ingredients into ice cream. 
 
Toppings were added and the ice cream was a success.
