Host a pet "Show and Tell" activity where children compare and contrast their pets. They will be practicing the scientific method of observation. Organizing a pet "Show and Tell" activity takes planning. Teachers should send a notice to parents that lets them know there will be a "Pet Show and Tell Day" at school. It should give the date and time and include the rules for having pets at school. For example explain how they will deal with cages, leashes and supervision of pets while at school.
During the activity have each child introduce his pet to the group. When all pets have been introduced, start a discussion with the children about how their pets are the same and different. Focus on size, color, fur, number of legs and shape.
Preschool children are curious about the world around them. They begin thinking about habitats or places where people, animals and other creatures live. A meaningful way to teach about habitats is to read books about pets and have children talk about their own pets. Some childrens books about pets are: "The Perfect Pet" by Margie Palatini, "Let's Go Visit-Best Friends Animal Sanctuary" by Nola Lee Kelsey and "Oh, the Pets You Can Get: All About Our Animal Friends" by Tish Rabe. After reading a book, ask the children to talk about where their pets live and why pets live in different kinds of habitats.
Understanding the world entails understanding the concept of categorization. Pets fall into categories such as dogs, cats, fish, birds etc. Being able to recognize the differences between the categories of pets is one step toward deeper science knowledge. During circle time, ask children to get into same pet groups (dogs, cats etc.). Have each group decide on three things that makes a dog different from other pets and then tell these to the whole group. When each group has shared their information, facilitate a discussion about the different categories of pets.
Preschool children wonder about the concept of living and nonliving things. Going on a nature hunt is a good way to learn about these science concepts. Before going on the hunt, talk with students about what makes something alive such as growing, eating and changing. Take a walk outdoors and have children collect objects that are alive and not alive. Bring these back to the classroom for further discussion.
