5.PS1.1.2 A model showing that gases are made from matter particles that are too small to see and are moving freely around in space can explain many observations, including the inflation and shape of a balloon; the effects of air on larger particles or objects.
5.PS1.2.2 No matter what reaction or change in properties occurs, the total weight of the substances does not change. (Boundary: Mass and weight are not distinguished at this grade level).
5.PS1.3 Make observations and measurements to identify materials based on their properties.
5.PS1.3.1 Measurements of a variety of properties can be used to identify materials. (Boundary: At this grade level, mass and weight are not distinguished, and no attempt is made to define the unseen particles or explain the atomic-scale mechanism of evaporation and condensation.)
5.LS2.2.3 Newly introduced species can damage the balance of an ecosystem.
ESS1 Earth's Place in the Universe
5.ESS1.1 Support an argument with evidence that differences in the apparent brightness of the sun compared to other stars is due to their relative distances from Earth.
5.ESS1.1.1 The sun is a star that appears brighter than other stars because it is closer to Earth.
5.ESS1.1.2 The sun is a star that appears larger than other stars because it is closer to Earth.
5.ESS1.1.3 Stars range greatly in their distance from Earth.
5.ESS1.2 Represent data in graphical displays to reveal patterns of daily changes in the length and direction of shadows, in addition to different positions of the sun, moon, and stars at different times of the day, month, and year.
5.ESS1.2.1 The orbits of Earth around the sun and of the moon around Earth, together with the rotation of Earth about an axis between its North and South poles, cause observable patterns. These include: day and night; daily changes in the length and direction of shadows; and different positions of the sun, moon, and stars at different times of the day, month, and year.
5.ESS3.1 Obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environments.
5.ESS3.1.1 Human activities in agriculture, industry, and everyday life have had major effects on the land, vegetation, streams, ocean, air, and even outer space. But individuals and communities are doing things to help protect Earth's resources and environments.
