How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

All biological cells require the transport of materials across the plasma membrane into and out of the cell. By infusing cubes of agar with a pH indicator, and then soaking the treated cubes in vinegar, you can model how diffusion occurs in cells. Then, by observing cubes of different sizes, you can discover why larger cells might need extra help to transport materials.

Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.

Students hypothesize whether vinegar and ammonia-based glass cleaner are acids or bases. They create designs on index cards using these substances as invisible inks. After the index cards have dried, they apply red cabbage juice as an indicator to reveal the designs.

Students learn the basics of acid/base chemistry in a fun, interactive way by studying instances of acid/base chemistry found in popular films such as Harry Potter and the Prisoner of Azkaban and National Treasure. Students learn what acids, bases and indicators are and how they can be used, including invisible ink. They also learn how engineers use acids and bases every day to better our quality of life. Students' interest is piqued by the use of popular culture in the classroom.

Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator. They review the concepts of pH and respiration and extend their knowledge to measuring the effectiveness of bioremediation in the environment.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Cancer cell growth depends on the production of new blood vessels by tumor endothelial cells in a process called angiogenesis. But the growing cancer cells produce large amounts of lactic acid as a byproduct of glucose breakdown. How tumor endothelial cells are able to survive in this toxic environment is unclear. In a recent study, researchers sought to uncover the mechanism of tumor endothelial cell survival in a lactic acid-rich tumor microenvironment. Using genetics and proteomics, they compared the RNA and protein levels of pH-regulating proteins in tumor endothelial cells to those in normal endothelial cells. They found that carbonic anhydrase 2 (CAII), an important pH regulator, was elevated in tumor endothelial cells, which was induced through the VEGF signaling pathway. Blocking CAII in tumor endothelial cells decreased cell survival in lactic acid conditions, and treating tumor-bearing mice with a CAII inhibitor had decreased lung metastasis..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.

How can an understanding of pH—a logarithmic scale used to identify the acidity or basicity of a water-based solution—be used to design and create a color-changing paint? This activity provides students the opportunity to extract dyes from natural products and test dyes for acids or bases as teams develop a prototype “paint” that is eventually applied to help with a wall redesign at a local children’s hospital. Students learn about how dyes are extracted from organic material and use the engineering design process to test dyes using a variety of indicators to achieve the right color for their prototype. Students iterate on their dyes and use ratios and proportions to calculate the amount of dye needed to successfully complete their painting project.

In this capstone course students will use new and previous knowledge about drug delivery to design capstone innovation project. Throughout the course students will engage in learning opportunities in drug delivery, gain a better understanding of anatomy and physiology related to drug delivery, and participate in a self-directed project to solve a problem. This learning tool will guide students through the process of understanding drug delivery and how drug delivery is applied to treating infectious diseases. DDF’s capstone project is aligned with NGSS and Common Core standards in math and ELA core curriculum. The learning activities, final project, and mid-unit assessments are provided to the teacher and students in the form of eLearning readings, quizzes, interactive tools, and presentation outlines. Students using this module should find success in self-directed learning, though the of use additional resources in the community, at school, at DDF, and in scientific literature, may help them achieve their goal.For more information about expanded learning opportunities, questions about the program, and assistance with learning tools, please contact our DDF eLearning Project Manager Lindsay Malcolm: lmalcolm@tsrlinc.com
