Humans

Humans, or Homo sapiens, are the only extant members of the subtribe Hominina and are characterized by their bipedal locomotion, complex brain structure, and advanced tool-making abilities. They are part of the primate family and are considered to be the most intelligent and advanced species on Earth.

Physical Characteristics

Bipedal Locomotion: Humans walk upright on two legs, a key characteristic that distinguishes them from other primates.
Brain Structure: The human brain is highly developed and allows for complex cognition, problem-solving, and language abilities.
Tool-Making Abilities: Humans have the ability to create and use tools, which has been essential to their survival and development as a species.
Diverse Physical Features: Humans exhibit a wide range of physical traits, including different skin colors, hair textures, and facial features, influenced by genetic and environmental factors.

Biological Systems

Humans have various biological systems that work together to maintain homeostasis and ensure survival. These systems include the respiratory, circulatory, digestive, nervous, and endocrine systems, among others. Each system performs specific functions that are essential for the overall health and functioning of the human body.

Behavior and Society

Humans are social beings and often form complex societies with intricate cultural, political, and economic structures. They exhibit a wide range of behaviors, emotions, and communication methods, including spoken and written language, gestures, and facial expressions.

Study Guide

What are the key characteristics that distinguish humans from other primates?
Explain the importance of bipedal locomotion in human evolution.
Discuss the role of the human brain in cognitive development and problem-solving abilities.
Describe the diversity of physical features observed in the human population.
Identify and explain the functions of at least three biological systems in the human body.
Discuss the significance of social behavior and cultural development in human societies.

By studying these topics, you will gain a deeper understanding of the characteristics, biology, and behavior of humans, as well as their role in society and the natural world.

Introduction to matter

The resources above cover the following skills:

Science, Grade 6, Adopted 2017 – The provisions of §§112.18-112.20 of this subchapter shall be implemented by school districts beginning with the 2018-2019 school year.

Introduction.

Grade 6 science is interdisciplinary in nature; however, much of the content focus is on physical science. National standards in science are organized as multi-grade blocks such as Grades 5-8 rather than individual grade levels. In order to follow the grade level format used in Texas, the various national standards are found among Grades 6, 7, and 8. Recurring themes are pervasive in sciences, mathematics, and technology. These ideas transcend disciplinary boundaries and include change and constancy, patterns, cycles, systems, models, and scale. The strands for Grade 6 include the following.

Matter and energy.

Matter can be classified as elements, compounds, or mixtures. Students have already had experience with mixtures in Grade 5, so Grade 6 will concentrate on developing an understanding of elements and compounds. It is important that students learn the differences between elements and compounds based on observations, description of physical properties, and chemical reactions. Elements are represented by chemical symbols, while compounds are represented by chemical formulas. Subsequent grades will learn about the differences at the molecular and atomic level.
