Start this lesson by asking students where certain items come from that they use in every day life. Some examples and their answers are listed below.
- yarn-animals such as sheep and plants such as cotton
Look at some items around the room and discuss where they originated from. When you finish this first part of lesson plans for second grade science on where items come from, students should have a good idea that all items originate from something else and that some organisms as well as nonliving things have many uses. Be prepared for answers to correspond with where students live. For instance, students living in a rural area may already understand that milk and eggs come from farm animals, while inner city students may understand the concept of production, but may also assume that milk and eggs come from the nearby grocery store. Try to begin the lesson so that the items discussed closely correspond with the area the students live in so that it is an easier concept for them to grasp.
As you move on to the next portion in this production theme, ask students to pick one organism or nonliving thing and describe how it is used in production. Students should be able to come up with at least three things that the item is used for. For instance, a cow can be used for milk, beef and leather.
As a homework assignment, ask students to go home and make a list of 5 things in their homes. Once they have listed five items they should then try to figure out where the item originated from. Since some items are made of more than one thing, ask students to list the largest portion of the item. For example, if the student picks a pencil, they should list that the pencil is made from wood and is therefore made from trees even though the pencil has lead in it that does not come from trees. You may want to send a note home to parents explaining the assignment.
