Science centers provide an engaging way for young learners to explore related concepts. The hands-on nature of each exercise secures the stimulation necessary to maintain focused attention. In this article, the authors describe a multi-day 5E (Engage, Explore, Explain, Elaborate, Evaluate) lesson on nocturnal and diurnal animals with science…

Many high school students learn about nutrient cycling during biology, environmental science, and agriculture classes. These lessons often focus on soil and plants, and nutrient cycling is usually taught independently from climate change. Scientists know that animals, including fish, can have strong effects on nutrient cycling (i.e., nitrogen and…

According to the National Survey of Science and Mathematics Education (2018), only 16% of the elementary teachers surveyed reported including hands-on activities in all or most of their lessons. Strategies that engage students in hands-on investigations help improve student achievement (Minner, Levy, and Century 2010) and provide students with a…

Food safety science is an important field due to its practical applications in maintaining public safety and confidence in consumer goods. A significant component of food safety science is the detection and regulation of heavy metals in food. Heavy metals such as mercury (Hg) are of particular concern because of their potential to damage the…

A high variety of experimental model organisms have been used in developmental biology practical lectures. The work with developing embryos is crucial to make students aware of the multiple biological phenomena underlying normal animal embryogenesis and morphogenesis and represent a unique experimental platform to analyze the impact of molecular…

This high school-level, place-based, inquiry-driven laboratory module familiarises students with techniques used to analyse animal behaviour while facilitating the development of the observational skills highlighted by the Next Generation Science Standards (NGSS). Throughout the module, students observe, quantify, and discuss local invertebrate…

While curriculum designed as project-based learning is not suitable for use with every science standard, this methodology can be used when teaching concepts that naturally contain some flexibility. With small adaptations, teachers can implement these practices into the classroom regardless of the grade level. This article provides a detailed…

All educators want their classrooms to be inviting areas that support investigations. However, a common mistake is to fill learning spaces with items or objects that are set up by the teacher or are simply "for show." This type of setting, although it may create a comfortable space for students, fails to stimulate investigations and…

The use of fossils as a tool in the classroom provide the medium in which students enthusiastically and directly engage in scientific exploration and thinking, enhancing their interest in future science curricula, and provide an avenue to develop scientific literacy. The National Research Council stated that students should have authentic…

In this article, a class of preschool children completed a week of lessons on worms in preparation for a visit by real worms. Prior to the real worm visit, the students learned about the bodies of worms. They also learned vocabulary words such as "segments." They documented thoughts and predictions about worms using drawings. Preparing…

A series of three practical sessions are designed to give students firsthand experience with the preparation of natural product extracts and assay using a live tissue preparation. Areca or betel nuts are the seeds from the fruit of the "Areca catechu" palm tree that is known to contain a number of pharmacologically active alkaloids. The…

Youth are introduced to STEM topics through informal settings like science camps, aquaria, and zoos. In these interactive and sensory-rich environments, a well-designed programme can help participants to acquire knowledge and cultivate interest through experiential learning. Given the importance of informal activities in environmental education,…

A multiweek protein purification suite, suitable for upper-division biochemistry or biotechnology undergraduate students, is described. Students work in small teams to isolate the enzyme lactate dehydrogenase (LDH) from a nontraditional tissue source, mammalian blood, using a sequence of three column chromatographic procedures: ion-exchange, size…

Students who are blind or visually impaired (BVI), like all students, need to conduct scientific investigations that involve measurements and reading experimental procedures. Best instructional practices for BVI students include touch and hearing experiences. Related strategies and tools include electronic textbooks, assistive technologies such as…

Biological flight mechanics is typically taught in graduate level college classes rather than in secondary school classes. We developed an interdisciplinary unit for advanced upper-level secondary school students (ages 15-18) to teach the principles of flight and applications to biological systems. This unit capitalised on the tremendous…
