Material Required
- Snow (ideally freshly fallen, fluffy snow)
- Thermometer (for determining temperature)
- Mittens or gloves (to keep hands warm)
- Stopwatch or timer (for data collection)
- Snow kinds (if accessible, e.g., wet snow, powdery snow)
Procedure
- Choose a Location: Find a location with enough clean snow for the experiment. Make sure it’s free of garbage and strange things.
- Temperature Measurement: Using the thermometer, determine the temperature of the snow and the surrounding surroundings. Take this as your starting temperature.
- Gather Snow: Gather enough snow to make multiple snowballs. Firmly pack the snow to produce regular, round snowballs. Each one should be the same size and form.
Experiment 1: The Influence of Temperature
Make two snowballs out of the snow from the same location. Hold a snowball in your hands for a few minutes to gradually reheat it. Allow the second snowball to remain at its original temperature.
Observe any differences in packing and tossing after warming one snowball against the unwarmed snowball.
Experiment 2: Influence of Snow Type
Make snowballs with each sort of snow available (for example, moist snow and powdery snow).
Compare how easy or challenging it is to pack and toss different textures of snowballs.
Keep a journal of your observations:
Keep the following in mind:
- How easy does the snow compact into a snowball?
- How well does the snowball keep its shape while being packed and thrown?
- How far does each snowball go when launched with equal force?
This experiment teaches youngsters about how temperature and snow type affect snow characteristics and snowball behavior. It also teaches concepts such as matter states and the impact of temperature on materials.
4. Frozen Bubbles

- Bubble solution (store-bought or homemade with water, dish soap, and glycerin)
- To blow bubbles, use a bubble wand or a straw.
- Freezing temperatures (below 32°F or 0°C) in an outdoor location
- A piece of black paper or fabric to place behind the bubbles for improved visibility is optional.
Procedure
- Make the Bubble Solution: Pour the store-bought solution into a container. In a basin, combine water, dish soap, and a tiny bit of glycerin if making your own.
- Select an Appropriate Location: Make sure you’re in an outdoor area with temperatures below freezing. On a frigid winter day, this could be in your backyard or a park.
- Blow Bubbles: Create bubbles by dipping the bubble wand or straw into the bubble solution and gently blowing bubbles. Make sure the bubbles are large enough to be seen.
- Examine the Freezing Process: You’ll see that the bubbles begin to freeze as they float in the cold air. Keep an eye out for the transition from liquid to solid as ice crystals grow on the surface.
- Examine Ice Patterns: Keep an eye out for the beautiful patterns that form on the surface of the frozen bubbles. The arrangement of ice crystals creates these patterns.
Observations:
- As the bubbles freeze, they will change from their original spherical shape to more irregular ones.
- On the surface of the bubbles, delicate ice crystals will grow, producing stunning patterns.
- The frozen bubbles will gradually collapse and shatter, leaving behind frozen soap film residues.
The experiment Frozen Bubbles is a visually appealing display of the physics of freezing. It depicts the transition from a liquid (soap bubble) to a solid (ice) state and allows the viewer to observe exquisite ice crystal forms. It’s a fun and memorable method to learn about how freezing temperatures affect matter.
