Quarry Hill - Winter Survival

During our socks experiment we discovered some fabrics protect you from the cold better than others.

Place our results in order from BEST thing to wear to the WORST.

• Bare Feet (Nothing)

• Wet Wool

• Wet Cotton

• Dry Cotton

• Dry Wool

Temperatures outside can vary wildly. But there is one part of our environment that is relatively stable. If you were a hibernating animal that needed a stable temperature to sleep, where would you go?

• In a snow pile

• In the water

• In the ground (earth)

• Out in the open air

• On a windy cliff

The cells that make your body are made of 70% or more of water.

When it gets cold outside what can happen?

• The water freezes, expands, and destroys the cell

• The water freezes, shrinks, and puts the cell to sleep

• The water stays liquid, but leaks out of the cell and kills it

• The water turns to gas, expands, and destroys the cell

School was canceled on the 21st of January 2025 because of the cold. The average temperature for the day was about -5 and the average wind speed was about 15 mph.

If your cells froze solid you would get frostbite or die. But a wood frog can freeze totally solid and wake up in the spring like normal. How do they do this?

• Wood frogs can survive freezing by hibernating in mud.
• Wood frogs have a special skin that prevents ice formation.
• Wood frogs generate heat to melt the ice around them.
• Wood frogs use special sugars to make an antifreeze in their body.

Dealing with the cold is hard. Animals have developed many strategies to deal with this.

Match the animal with it's survival strategy.

• Hibernate or Sleep/Nap

• 
• Freezes, but remains alive

• 
• Insulates and Stays Active

• 
• Migrate

• 
• Lays eggs

Although as humans we worry about having too much fat, it is essential to have some in our bodies.

In the thermometer experiment we discovered which use for fat?

• Fat is a good insulator and helps protect us from the cold.

• Fat is used as a cushion in our bodies to protect organs

• Fat can make your body to warm and overheat

• Fat helps you store energy, which you use to fight off hypothermia
