Get involved in our February Science Challenge - Homemade Slushy
Science Challenge - Homemade Slushy
Resources:
- Ice
- Salt
- 1 small resealable plastic food bag
- 1 larger resealable plastic food bag
- Fruit juice/smoothie
- Cup or glass
- Towel
Instructions:
- Half-fill the small food bag with your choice of drink and seal it well. *You will need adult help for this*
- Half-fill the large food bag with ice, sprinkle 2 tablespoons of salt over the ice, and mix well.
- Place the bag with your drink inside the ice and salt bag. Gently roll the salt mixture around it. If the bag gets too cold to touch, cover it with a towel so you can keep rolling the ice around.
- After a few minutes, the juice/drink will turn into slush!
Please send a photo on Class Dojo to your teacher. All entries will receive a sticker.
The Science
Salt lowers the freezing point of ice, which makes it melt. The more salt you add, the lower the freezing point (up to a point, it won’t keep going down). For the ice to melt, heat must be absorbed from the juice and this causes it to freeze.
Science of the Month: Healthy Living
Choose one of the following topics to investigate:
- Compare the differences between our lifestyle now and the past (e.g., Victorians, Romans, Egyptians).
- Find out the 5 different food groups. Can you give an example of a food from each group?
- How can a lack of sleep and poor nutrition affect our bodies?
