This science unit focuses on measuring skills using students' own sneakers and the unit of measure. Two activities with differing levels of difficulty are presented. (MT)

Using the problem of trash disposal as an example, students participate in science activities designed to develop the following science skills: classifying, observing, measuring, communicating, inferring, and predicting. Activities are described in detail and a reproducible page is provided. (JL)

Guidelines help elementary educators understand what they will be teaching in science programs, how they will assess student learning, and how they will be trained. Science programs should develop scientific literacy via hands-on, collaborative, inquiry-oriented lessons centered on processes used by real scientists in their everyday work. (SM)
