1.
Ella wanted to know if water freezes faster on its own or when
added sugar.
2. Ethobserved that the sugar she added was completely dissolved
in the water. And noticed that the water with sugar starts to
Solidify on the first 15 minute intervale she recorded it based on
3. She filled the two identical containers with same amount
of
room temperature water. Then, added a measured amount of
Sugar to one container, placed both containers into the freezer.
At 15-minute interval, she opened and observed the status of
water inside the container until both are completely frozen.
4. She thought that there will be no
difference in the time for the
water to freeze whether added with sugar or not.
5. Based on the data, Ella came up that the water with sugar
freezes faster than the one with
no sugar added.
6. Ella found out on her science book that when you add sugar to
water, the water (the solvent) becomes a solution. Adding sugar
disrupts the liquid state because sugar molecules move around
without direction, making the liquid water molecules less
organized. The more solute particles there are in the water, the
greater the freezing point.
