Students often need to obtain, organize, clean, and analyze data in order to draw conclusions about a particular phenomenon (e.g., why tidal heights change). When conducting a science investigation in biology, chemistry, physics, or Earth science, data can be collected by the student or can be provided to them via secondary data sets. This article…

Space is a key area of science that is often taught in year 5 (ages 9-10) in English schools and related to this is gravitational force. Almost without exception children enjoy learning about the solar system and beyond. This article introduces a series of activities for children to explore the formation of impact craters in the solar system. The…

In 1919, Eddington and Dyson led two famous expeditions to measure the bending of light during a total solar eclipse. The results of this effort led to the first experimental confirmation of Einstein's General Relativity and contributed to create its unique and enduring fame. Since then, similar experiments have been carried out all around the…

Our 4th grade year has become known as "the field trip year", with over 10 trips carefully aligned with learning units across the year. This article describes the first trip of the year, which in many ways sets the stage for students' effective use of field trips as engaging extensions and applications of classroom learning. The Pike's…

The study of earthquakes can help students build connections between theoretical analysis and real-world applications. However, units on earthquakes typically struggle to bridge that gap between theory and application. Traditional class activities focus on measuring earthquakes, such as triangulating epicenters by analyzing P and S wave arrival…

Micrometeorites originate from small pieces of rock from space colliding with the Earth's atmosphere at high velocity, such as the Perseid meteors which hit the atmosphere at 60 km/s. When they do so, they burn up, causing a flash of light that we see as a meteor. Many groups have been successful collecting these particles using various devices.…

Observing and documenting elements of weather teach children about using tools and their senses to learn about the environment. This column discusses resources and science topics related to students in grades preK to 2. This month's issue describes an activity where students indirectly document local weather by counting outdoor clothing types worn…

Students learning the skills of science benefit from opportunities to move between the scientific problems and questions they confront and the mathematical tools available to answer the questions and solve the problems. Indeed, students learn science best when they are actively engaged in pursuing answers to authentic and relevant questions. We…

In a previous article we demonstrated that a simple, passive external circuit incorporating a thermistor, connected to a mobile device through the headset jack, can be used to collect temperature data. The basic approach is to output a sine wave signal to the headset port, through the circuit, and input the resulting signal from the headset…

National Geography Standard 1 requires that students learn:"How to use maps and other geographic representations, geospatial technologies, and spatial thinking to understand and communicate information" (Heffron and Downs 2012). These concepts have real-world applicability. For example, elevation contour maps are common in many…

Understanding how scientific conclusions are drawn from data is central to learning about the nature of science. Many students struggle with aspects of reasoning from data, including identifying relationships among variables, interpreting graphs, coordinating theory and evidence, and not allowing personal beliefs to outweigh the data when forming…

Instrumentation available for teachers and students has changed considerably during the last 20 years. The data logger-sensor system has the advantage of taking reliable measurements over time with suitable sample rates. This experiment is not an open-ended investigation but an opportunity to explore the established relationship between the…

Most students globally have mobile devices and the Global Students Laboratory (GlobalLab) project is integrating mobility into learning. First launched in 1991, GlobalLab builds a community of learners engaged in collaborative, distributed investigations. Long relying on stationary desktop computers, or students inputting their observations by…

Teaching students to make daily weather observations is one way educators assist them as they learn to dress appropriately. In addition, it provides a natural and developmentally appropriate link between science and other curriculum areas, such as literacy and language development. The "Next Generation Science Standards" (NGSS Lead…

The decline in hummingbird populations and shifts in their movements may adversely affect their role as pollinators and, in turn, plant biodiversity (Allen-Wardell et al. 1998). For example, Hadley et al. (2014) discovered that larger fragments of forest correlated with larger hummingbird populations and more seeds of "H. tortuosa" being…
