Objective: Children will explore properties of insulation as they experiment with covering bottles of water with different materials.‹ Return to Theme
In colder weather, people usually wear coats when going outside. Coats keep us warm because of the material of the coat. Our body supplies the heat, and the material helps to trap body heat and keeps the heat from escaping into the air. This is what keeps us warm. Other items that can be worn to maintain warmth are hats, gloves or mittens, and scarves. Hats help keep in body heat by blocking the escape of body heat through the head. Scarves worn around the neck help to keep bare skin from exposure to cold temperatures. Gloves or mittens can protect hands from cold temperatures.
Many different materials can act as insulators to keep heat in. In our activity, the newspaper and the scarf were the insulators and helped to keep the warmth from the water bottle from escaping into the air. Newspapers are made up of layers. These layers keep the heat from escaping into the air and act as a shield. Scarfs are made of layers of fabric or yarn that also serve as a shield. It takes the heat longer to pass through the paper or the fabric than to pass through the air.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
While we believe that the books and resources recommended may be of value to you, keep in mind that these are suggestions only and you must do your own due diligence to determine whether the materials are appropriate and suitable for your use.

There are currently no Common Core Standards for pre-k, but these lessons are aligned as closely as possible to capture the requirements and meet the goals of Common Core Standards. However, these lessons were neither reviewed or approved by the National Governors Association Center for Best Practices or the Council of Chief State School Officers, which together are the owners and developers of the Common Core State Standards.
