Venus
Venus is the second planet from the Sun and the hottest planet in our solar system. It is often referred to as Earth's sister planet due to its similar size and composition.
Physical Characteristics of Venus
- Size: Venus is similar in size to Earth, with a diameter of about 12,104 kilometers.
- Atmosphere: Venus has a thick atmosphere composed mainly of carbon dioxide, with clouds of sulfuric acid that cause a greenhouse effect, trapping heat and making it the hottest planet in the solar system.
- Surface: Venus has a rocky, geologically young surface with many volcanoes and large impact craters. It is also covered in plains and highland regions.
- Rotation: Venus rotates in the opposite direction to most planets, a phenomenon known as retrograde rotation.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
