The purpose of this article is to describe a modeling sequence about the digestive system. "What happens in your body when you have lactose intolerance?" is the initial question that will guide the activities. Students will build a 3D plaster cast of the digestive system as part of a modeling cycle through which they are expected to…

X-rays are such an important and familiar part of the electromagnetic spectrum, but is there a way to safely bring x-rays into your lecture? The demo team at the University of California at Berkeley seems to have managed this. They have an x-ray safe box that they use to produce a live x-ray image on a fluorescent screen. In this article, we…

"Productive Uncertainty in Science Education" provides the support that teachers and students need for more complex science investigations. Science is driven by the need to manage uncertainty--uncertainty about how to explain the world, but also how to represent the world in an investigation, what to measure, and how to convince peers to…

We report on a distance learning experimental project for chemistry-major students on the synthesis of ethyl dodecanoate (C[subscript 11]CO[subscript 2]Et), a model for biodiesel, considering green chemistry principles. Thus, we employed a "recyclable acid catalyst" (an ionic liquid) and used chemometrics and microwave heating (MW) to…

Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

Children often have very stereotyped views of science and scientists, far removed from their own lives. Getting children to 'become' scientists and feel that they are actually "doing" science, being involved in something pertinent to them and their environment, is a goal of modern science teaching. This article aims to illustrate how…

It can be hugely beneficial for teachers to 'buy in' an expert for a day in an area that they are focusing on. Children are inspired by a special visitor and it can provide a new perspective to a topic and invigorate and extend learning. The variety of workshops and visitors available is astonishing. Students can be transported to outer space or…

Embedding science learning in real-world issues is a research-based way to generate student enthusiasm, interest, and motivation for science. The authors advocate teaching secondary science in the context of "socio-scientific issues" (SSI). SSI are authentic societal challenges with connections to science, such as climate change,…

The author writes about taking on the role of Science Coordinator, changing expectations, and raising the profile of science in her school.

Maximizing classroom time to include meaningful content-based learning with fun engaging activities that simultaneously challenge and encourage students is a hallmark of a successful school day. This article shares one instructional approach that does a model eliciting activity (MEA). A MEA is a real-world, problem-based scenario framed around a…

Take a selection of balls and marbles along to a nearby playground slide and let students investigate factors that may influence how balls accelerate down an inclined plane. Students can make hypotheses in small groups, plan investigations to test multiple possible explanations and draw conclusions about the importance of different variables. The…

The unequal distribution of natural resources is the direct result of past geologic processes. Once a promising region is located, geologists use a variety of techniques to find the materials and energy that society consumes. Their tools can be as simple as a hand lens or as sophisticated as a satellite. Along the way, exploration geologists and…

As schools in England re-open their doors and welcome children back in September 2020 after the COVID-19 lockdown, what can, and should, primary science look like in the 'new normal'? If timetables are constricted to adhere to the demands of social distancing, innovative practical science enquiry will be needed. Even if they are not, the…

Teachers from Kates Hill Primary School describe uniting the school in a vision for science and raising the profile of science through enrichment by using Explorify.

It is common for high school physics teachers to comment on the challenges they face in supporting students' graph drawing skills, knowing their importance for the study of physics. This paper suggests a novel and alternative way to support students to develop their graph drawing skills as well as teach them about sound, frequency, and amplitude.…
