This pathways explores one of the fundamental forces of nature: the Law of Universal Gravitation, first formulated by Isaac Newton. There are explanations of how to use the law to calculate forces between different bodies, as well as some application sof this law. There are questions at the end of the pathway to check for understanding of the topic.

This pathway introduces the concept of vaccination, how vaccines are developed, and the purpose of clinical trials during vaccine development. The coronavirus SARS-CoV-2—which causes COVID-19—serves as an example.

Esta vía demuestra cómo una herramienta fundamental en biotecnología, la electroforesis en gel de ADN, puede utilizarse para verificar la producción exitosa de un plásmido recombinante. Esta vía es compatible con los laboratorios ABE 4 y 4a.

This pathway demonstrates how a fundamental tool in biotechnology, DNA gel electrophoresis, can be used to verify successful production of a recombinant plasmid. This pathway supports ABE labs 4 and 4a.

This pathway provides an introduction to the structure of water and properties of water, such as hydrogen bonding, that make it essential for life. For a deeper look at this topic, we recommend the pathway The Chemical Foundation of Life from the OpenStax textbook Biology for AP® Courses.

This pathway introduces the concept of waves. Properties of waves are defined, such as frequency, wavelength and period. Examples of waves in different media are given, as well as observable properties. Problems are provided to check for understanding.

This pathway explores the fundamental concept of energy, and how energy can be transferred between objects. Different types of energy are defined, and the law of conservation of energy is explained. Simple machines are explained as a way of making energy transfer between objects easier. Problems are provided to check understanding.

A new virtual interview series from LabXchange at Harvard University, the Xchange showcases the diverse roles, projects, and initiatives that make up the intersecting fields of science, education, and health. Hosted by LabXchange Faculty Director Robert Lue, the first season features a range of perspectives on the impact of COVID-19.
