Dry ice

Science

• The First-grade child learned that dry ice is the solid form of carbon dioxide.
• They learned that dry ice undergoes sublimation, which means it changes directly from a solid to a gas without melting into a liquid.
• They observed that dry ice produces smoke or fog-like vapor due to the sublimation process.
• They discovered that dry ice is extremely cold and can cause frostbite if touched directly.

For continued development, encourage the child to conduct further experiments with dry ice, such as exploring its effects on different materials or creating dry ice bubbles. They can also research other uses of dry ice in real-life situations, such as in the entertainment industry or for preserving food.
