5th Grade Science Facts
The Nature of Science and Engineering
1. Science is a way of knowing about the natural world, is done by individuals and groups,
and is characterized by empirical criteria, logical argument and skeptical view.
2. Scientific inquiry requires identification of assumptions, use of critical and logical
thinking, and consideration of alternative explanations.
3. Men and women throughout the history of all cultures, including MN American Indian
tribes and communities, have been involved in engineering design and scientific inquiry.
4. Tools and mathematics help scientists and engineers see more, measure more
accurately, and do things that they could not otherwise accomplish. (spring scale, metric
measurement, tables, mean/median/range, spreadsheets, and appropriate graphs)
Physical Science
1. An object’s motion is affected by forces and can be described by the object’s speed and
the direction it is moving.
2. Friction slows down a moving skateboard.
3. A greater force on an object can produce a greater change in motion.
4. Simple machines demonstrate how they change the input and output of forces and
motion.
Earth and Space Science
1. The surface of the Earth changes. Some changes are due to slow processes and some
changes are due to rapid processes.
2. Over time, rocks weather and combine with organic matter to form soil.
3. Slow processes, such as water erosion and rapid processes, such as landslides and
volcanic eruptions, form features of the the Earth’s surface.
4. In order to maintain and improve their existence, humans interact with and influence
Earth systems.
5. Water, iron ore, granite, sand and gravel, wind and forests are all renewable and
nonrenewable energy and material resources found in MN.
Life Science
1. Living things are diverse with many different characteristics that enable them to grow,
reproduce and survive.
2. Plants and animals adapt to their environment. Without various adaptations, they
would not be able to survive.
3. Natural systems have many parts that interact to maintain the living system.
4. Humans change environments in ways that can be either beneficial or harmful to
themselves and other organisms.
5. Recreation, pollution, and wildlife management are examples of helpful and harmful
human interaction with natural systems.
