When heat energy is transferred from a warm to a cold object, one cools down and the other warms up, but the total energy remains the same. This model allows…
Explore what happens when a force is exerted on a metallic material. There are many different types of materials. Each material has a particular molecular structure, which is responsible for…
Observe changes in potential energy as molecules self-assemble into micelles.
Explore how mixing two different liquids together can result in less total volume by investigating at the molecular level.
Explore how an mRNA copy is made of DNA. Protein complexes separate the DNA helix to allow complementary mRNA nucleotides to bind to the DNA sequence. The pairing of nucleotides…
Explore how a protein is made from an mRNA sequence. In translation, the mRNA leaves the nucleus and attaches to a ribosome. Transfer RNA (tRNA) molecules bring amino acids to…
Add various unknown molecules to oil and water, and observe how the molecules sort themselves in response to interactions with the surrounding environment.
Explore the structure of a gas at the molecular level. Molecules are always in motion. Molecules in a gas move quickly. All molecules are attracted to each other. Molecules can…
Explore the structure of a liquid at the molecular level. Molecules are always in motion. Molecules in a liquid move moderately. All molecules are attracted to each other. Molecules can…
Explore the structure of a solid at the molecular level. Molecules are always in motion, though molecules in a solid move slowly. All molecules are attracted to each other. Molecules…
