Earth Science

Science learning is an important part of the K-12 educational experience, as well as in the lives of students. This study considered students’ science learning as they engaged in the instruction of scientific issues with social relevance. With classroom environments radically changing during the COVID-19 pandemic, our study adapted to teachers and students as they were forced to change from more traditional, in-person instructional settings to virtual, online instruction settings.

While tragedy has struck an inordinate number of students in the past several years, not all areas of the country are at risk for every natural hazard all the time. To avoid having students feel like Chicken Little under a falling sky, the GeoHazard project uses simulations, data, experimentation, and scientific argumentation to teach about risk and uncertainty. We have created three scaffolded online modules focused on hurricanes, wildfires, and inland flooding to help teach these concepts. Through investigations using both simulations and real-world data, these curriculum units introduce students to the scientific factors responsible for these hazards and provide practice in interpreting forecasts.

Concord Consortium’s new Earth Rocks Map displays a generalized representation of Earth’s geology, focused primarily on the distribution of the three major rock types (igneous, metamorphic, and sedimentary). What makes this map different is that it strips out information about geologic eras, highlighting the distribution of rocks found on Earth’s surface.

The Innovate to Mitigate project adapts crowdsourcing to support project-based STEM education, posing design challenges for secondary-school students. Students are charged with designing feasible innovative strategies to mitigate CO2 emissions and thus global warming. The paper draws on data from 3 project teams. The paper presents evidence that a web-mediated community of practice supports STEM learning of concepts and STEM practices and examines conditions under which the environment can enable an account of microgenesis of that learning.

Today’s students are exposed to news about wildfires on an all-too-regular basis. An increasingly larger portion of those students live in areas where wildfire risks are high or where smoke has reduced the air quality. The GeoHazard project has designed, developed, and tested an online wildfire curriculum module for middle and high school students that addresses the factors that influence wildfires, as well as the risks and impacts that wildfires bring to people and their communities.

Climate change, and the rise of the natural hazards that climate change brings, has been at the top of news feeds every week over the past year. Extreme events such as floods, droughts, and wildfires are expected to increase in the future. What does that mean for those of us living in the path of one of these hazards? Our GeoHazard project is exploring this question with middle and high school teachers and students across the country.

This article introduces a new online curriculum module called “What will Earth look like in 500 million years?” Using two web-based tools, middle and high school students develop understandings of (1) how collective movements associated with a system of plates create the current distribution of landforms found on Earth’s surface, and (2) how earthquakes and volcanoes provide important clues for interactions at plate boundaries.

The goal of our National Science Foundation-funded Geological Models for Exploration of Dynamic Earth (GEODE) project is to help students use plate tectonics as an explanation for the landforms and geological phenomena observed on Earth’s surface.

This article describes a free online plate tectonics curriculum module (PT module), which offers a unique approach with two innovative tools that allow students to make connections between real-world data and plate tectonics models.

High-quality science education is essential for students to become scientifically literate. Model-Evidence Link (MEL) diagrams and build-a-MEL (baMEL) diagrams are instructional scaffolds that create an opportunity for students to build scientific understanding through the evaluation of the connections between evidence and alternative explanations of a scientific phenomenon. The MELs and baMELs allow for a natural incorporation of three-dimensional learning that has been recommended by the Next Generation Science Standards to enhance students’ comprehension. Through this science teaching methodology, students are able to see that by diagramming and then writing about one’s thoughts about the connections between evidence and explanations, one can deepen their understanding of scientific concepts.
