Sunscreens have different levels of protection, measured most commonly with the sun protection factor (SPF). Students initially believed higher SPF factors mean greater sun protection and learned through this activity that higher SPF does not mean greater protection. Students analyzed the amount of ultraviolet radiation (UVR) protection and…

The unique organism project was designed as a culminating assessment for a biological classification unit in a middle school setting. Students developed a model to represent their unique organism. Using the model, students were required to demonstrate how their unique organism interacts with its environment, and how its internal and external…

This article describes the use of project-based instruction in activities and labs intended to develop higher-order thinking skills with high school students and pre-service teachers through the use of soap making.

The concept of funds of knowledge, as applied to an ethnically popular fruit, is the focus of this module. Teachers can use this concept to create contextually meaningful experiments that can contribute to a culturally relevant and more fully developed educational unit focusing on the science of nutrition and reflecting content Standards A and C.…

This study examines the process by which a teacher may be able to answer a question asked in the classroom by using a scientific approach and a simple activity. This article examines a discussion of the question "Is space light or dark?" Priority in the discussion has been given to determining students' preconceptions about the interaction of…

A priority for all biology teachers must be for students to leave the classroom with a broad knowledge and understanding of science. Students need to be critical of science, analyze science, and relate new science knowledge to their daily lives. Unfortunately, many students are not reaching this goal. One strategy for making science laboratories…

To find out about the microscopic life in the valuable estuary environment, it is usually necessary to be near the water. This dry lab offers an alternative, using authentic data and a simulation of plankton sampling. From the types of organisms found in the sample, middle school students can infer relationships in the biological and physical…

With archaeologists continually finding new pieces of the past, students will undoubtedly see and hear of new discoveries in the media. By using archaeology as a context for investigating past cultures and using science methods, teachers can capitalize on students' interests while still addressing concepts recommended (or required) for their…
