Summary: Students work in pairs or small groups to identify and categorize various objects. One student is blindfolded and the other student chooses five objects for their partner to identify. The blindfolded student has to describe and try to identify the object based solely on touch. Both students then record their data, describing the objects first as human-made or natural, then living or non-living, and finally physical characteristics. This activity can be modified to challenge different age groups. This activity would go well with a lesson on animal classification.

Summary: In small groups, students will experiment and observe the similarities and differences between human-made objects and nature. The students will compare the function and structure of hollow bones with drinking straws, bird beaks and tool pliers, and bat wings and airplane wings. A classroom discussion can be held to discuss similarities and differences that were observed along with follow up assessment activities such as journal writing and Venn diagrams.

Summary: Students test whether the color of a materials affects how much heat it absorbs. Students will place an ice cube in a box made of colored paper (one box per color; white, yellow, red and black), which they will place in the sun. The students will make prediction as to which color will melt the ice cube first. They will record the order and time required for the ice cubes to melt. This activity can be done independently or in conjuction with both a math and/or science lesson. A discussion and journal-writing period can follow. For a more challenging activity, a discussion about solar energy can be included.

Summary: Students will learn about how paper is made. Working together, students will make their own paper. This activity introduces students to recycling; what it is, its importance, and how it effects their lives.
