Let It Snow Five Wintery Experiments for Your Budding Scientists — by Jan Pierce W inter is a magical time for children and you can enhance their apprecia- tion and understanding of the season by conducting simple but serious science investigations right in your own home. Give your children a head start in mas- tering basic scientific methods of study by teaching them to investigate their world through prediction, observation, hypothesiz- ing, estimating, and record- ing their findings. Here are five simple snowy science experiments guaranteed to be both fun and informative. What Happens When Water Freezes? 1. Fill an empty metal container to ½ inch from the top with water. 2. Use a permanent marker to mark the water line on the outside of the can. 3. Predict what will happen when the water freezes. 4. Place the can on a tray or on alu- minum foil and place in the freezer overnight. The Ice Cube Race 5. Observe the ice line the next morn- ing and record the results. *Water expands as it turns to ice. Use the terms liquid and solid states. What will happen when the ice melts back into liquid state? 1. Place three ice cubes in identical containers. No Two Alike 3. Estimate the length of time it will take for each ice cube to melt com- pletely. 2. Leave one ice cube as it is, add salt to the second, and sugar to the third 1. On a snowy day, catch falling snowflakes on pieces of black poster board. 4. Observe at one minute intervals and record information. 2. Have a magnifying glass of at least 10X strength ready to observe the flakes. 5. Write a paragraph describing the rate of melting for each of the three cubes. 3. Observe individual flakes, taking note of their structure. 6. Can you explain why one melted faster? 4. Record your observations in draw- ings. *Which would you use to melt the ice on roadways, sugar or salt? Why? 5. How are the flakes alike? Differ- ent? Make Your Own Icicles *A snowflake is a single snow crystal of ice. The ba- sic shape of a snow crystal is a hexagonal prism. Once the ba- sic shape is formed, branching builds ad- ditional patterns. It’s true that no two snowflakes are alike. 1. Punch a hole in the bottom of a can. 2. Punch three holes around the top of the can. 3. Loop twine through the three holes and hang the can outside on a day when the temperature is 32 degrees or less.
