Collecting and Sorting
After receiving the items needed back from parents, you are ready to begin this lesson. Ask students if there is anything they collect at home. If not, ask them if there is anything they would like to collect. Encourage students to focus on small items that are easily transported. Talk with students about why they are interested in the items they collect or would like to collect. Ask about specific characteristics of the items.
Explain to students that they will be doing a science activity that involves collecting items. Explain that the items must be small. Use some of the suggestions below to interest students and give them an idea of what they will be collecting. Discuss what tools, if any, may need to be used when gathering items for the collection.
Give the students a week to gather their collection. Through the week, talk about grouping like items. You can practice this by asking students to group themselves according to being a boy or a girl or even group themselves according to what color they are wearing. At the end of the week, when the students return with their collection, ask all students to sit down with their collections and take them out of the container. What are some things the items in the collection have in common? What are some things that the items vary in? Ask students to divide their collection in the egg carton according to similarities, such as size or color. It is likely that you will have to help each student to properly divide their items and possibly even help them decided what factors they should be focusing on, but allow students to express their own ideas and opinions on these factors.
Once the items have been grouped accordingly, allow students to show the rest of the class their collection and explain why they divided the collection as they did. If students have similar collections, be sure to talk about how they were divided in similar or different ways.
Preschool science activities that involve collections are a great way for students to brush up on math and science skills and develop healthy hobbies at the same time!
