This educational film explores acid-base indicators and their color changes in response to acidity. It demonstrates how substances like tea, red cabbage, and litmus paper react when acids are added, ...

SIOUX CITY (KTIV) - Gather your supplies! In this episode we will use everyday materials to explore pH and how it changes between acids and bases. Blackberries contain a chemical class called ...

A classic experiment proving amino acids are created when inorganic molecules are exposed to electricity isn't the whole story, it turns out. The 1953 Miller-Urey Synthesis had two sibling studies, ...

Introduction Did you know that the juices in your stomach are nearly as acidic as lemon juice? Fortunately, your stomach has special cells that act as a barrier to the acid, preventing it from ...

Identify the independent (manipulated) and dependent (responding) variables in a scientific investigation. Draw conclusions about the relationship between two variables using quantitative data.

This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

Automation uncovers combinations of amino acids that feed two bacterial species and could tell us much more about the 90% of bacteria that humans have hardly studied. An artificial intelligence system ...

In 1952, a University of Chicago chemist named Stanley Miller and his adviser, Harold Urey, conducted a famous experiment. Their results, published the following year, provided the first evidence that ...

An innovative solution to creating more environmentally friendly batteries has been demonstrated by a team of researchers at McGill University in Canada, and the breakthrough came after some ...

Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the budding ...
