This module specifically focuses on Cellular Respiration, both aerobic and anaerobic. The breakdown of nutrient molecules provides energy to the cell. This energy is stored in specific chemicals that are used to carry out the life functions of the cell (BIO.2 e). This module was developed by Teresa Ballou as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.
Learn about many ways to combine art and science as we observe the world around us. We often think of scientists as methodical and precise, and artists as free-willed, impulsive creators. But did you know that some art has science packed right into it? And that artists throughout history have helped scientists conduct their work? Learn about the photography of Berenice Abbott who documented the changing New York skyline with photographs of architecture and urban design of the 1930s, and science interpretation in the 1940s to 1960s. Learn how to use the sun to air dry your salt dough creations and explore papier-mâché.
There is a lot of science to discover in your backyard! Check out this collection of activities to learn about wind, animals, plants and more.
Students will use key features (such as cell type, DNA, and structural similarities) to classify organisms into modern domains . They will also create and read model representations of classification to organize and demonstrate their understanding of evolutionary history. This module was developed by Liz Ashby as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.
Students will participate in a 5E lesson. To ENGAGE, students will connect their understanding of similarities between parent and offspring to the fundamental molecule of life: DNA. To EXPLORE, students will participate in interactives to observe, analyze and summarize how genes are used to create proteins and traits. In the EXPLAIN section, students will take notes on DNA replication and the Central Dogma. To ELABORATE on their understanding of DNA, students will participate in a protein synthesis race (game) to practice transcription and translation. Formative evaluations of students's ability to explain the process of protein synthesis include (1) a protein synthesis and codon practice sheet, (2) a labeling activity, and (3) making a recording that models and explain the process. As an extension, students can apply their understanding of mRNA to explain how the Pfizer and Moderna COVID-19 vaccines work. Finally, int summative EVALUATE, students model replication, transcription, and translation as they build an organism!
After the completion of this module students will understand that sound travels in compression waves and must have a medium to travel. Sound also travels in liquids and gases. Students will also understand that sound waves are created by vibrations and capable of transmitting energy.This module was developed by Sarah Donnelly as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.
The lessons in this module are empirical – abductive. The teacher helps students identify the activity of substances within pizza dough. The teacher announces the students will conduct chemical reactions to explore how matter is conserved during a chemical change. After the class compares their reasoning, the teacher provides clarifying and direct instruction with videos, guided practice and supported computer simulation practice for students to learn to balance chemical equations. Students complete a problem-based investigation to apply their learning by writing, testing and explaining a lab procedure that will help an absent classmate to gather evidence and gain an understanding of the Law of Conservation of Matter. This module was developed by Patricia Kramolisch as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.
In this unit, students will study the evolution of whales from four-limbed, land dwelling, mammalian ancestors to modern, two-finned, aquatic mammals through a virtual or in-class simulation lab. This activity will teach them more about how fossils, homologous structures, and DNA analysis provide evidence for macroevolution, evolutionary theory, and modern classification. This module was developed by Liz Ashby as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.
In the engage section of the 5Elesson, students are introduced to the role of fossils as evidence of evolution and evolutionary relationships by watching a videos about the discovery of Lucy and Ardi and consider what type of information that they can gain from skull fossils. Students will then explore features of skulls from human ancestors and the modern day Homo sapien. After measuring skull to cheekbone ratios, students will create a graph to compare various species. Several interactives are provided to explain fossils, skeletal evidence for human evolution, and phylogenetic trees. Then, students will apply their skills of analyzing data about anatomical similarities and genetic information to depict evolutionary relationships between organisms using cladograms. To evaluate student understanding, students will complete an evolutionary relationships CER.
Students will experiment with various light blocking materials and how they affect creation of shadows. Using this knowledge, student will participate in a series of activities manipulating and capturing shadows to inform their own work creating a 3D sculpture that casts a unique shadow.
Introduction to the Modeling and Analysis of Complex Systems introduces students to mathematical/computational modeling and analysis developed in the emerging interdisciplinary field of Complex Systems Science. Complex systems are systems made of a large number of microscopic components interacting with each other in nontrivial ways. Many real-world systems can be understood as complex systems, where critically important information resides in the relationships between the parts and not necessarily within the parts themselves. This textbook offers an accessible yet technically-oriented introduction to the modeling and analysis of complex systems. The topics covered include: fundamentals of modeling, basics of dynamical systems, discrete-time models, continuous-time models, bifurcations, chaos, cellular automata, continuous field models, static networks, dynamic networks, and agent-based models. Most of these topics are discussed in two chapters, one focusing on computational modeling and the other on mathematical analysis. This unique approach provides a comprehensive view of related concepts and techniques, and allows readers and instructors to flexibly choose relevant materials based on their objectives and needs. Python sample codes are provided for each modeling example.
Carbon and other elements play a key role in determining the structure and function of macromolecules needed to sustain life processes. Life processes include growth and repair, reproduction, gas exchange, metabolism, and response. Cells make a variety of macromolecules needed for life processes from a relatively small set of monomers. These macromolecules include carbohydrates, proteins, nucleic acids, and lipids. This module was developed by Kristin Scheible as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.

Almost Every possible environment on Earth is home to a living organism, no matter how hostile the environment may seem. But what can these extremophiles tell us about life on our planet or the possibility of life in the universe?
Where do we find extremophiles? We look for environments that push the limits for ordinary living organisms. NASA conducts analog testing in these extreme environments to better understand life on Earth and identify the potential for life in the universe.
Living things must move materials into, out of, and within the cell. Substances can move across the cell membrane passively (i.e., osmosis and diffusion) or actively (i.e., active transport). This module focuses on the two types of cellular transport and assumes knowledge of cell membrane (components and functions, ie. Fluid Mosaic Model) has already been addressed. This module was developed by Teresa Ballou as part of a Virginia Commonwealth University STEM initiative sponsored by the Virginia Department of Education.
