S:ESS1:2:7.1 Recognize that water can be a liquid or a solid; and explain that it can be made to change from one state to the other, but the amount (mass) of water always remains the same in either state.
S:ESS2:2:4.1 Recognize that the Sun, Moon and stars all appear to move slowly across the sky.
S:ESS2:2:4.2 Recognize that as the position of the Sun changes in relation to the Earth it creates shadows of varying length and direction.
S:ESS2:2:4.3 Explain that people should not look directly at the Sun because it is dangerous and may cause injury to the eyes.
ESS3 The origin and evolution of galaxies and the universe demonstrate fundamental principles of physical science across vast distances and time.
1 Size and Scale
2 Stars and Galaxies
S:ESS3:2:2.1 Recognize there are too many stars to count, and that they are unequal in their brightness.
ESS4 The growth of scientific knowledge in Earth Space Science has been advanced through the development of technology and is used (alone or in combination with other sciences) to identify, understand and solve local and global issues.
1 Design Technology
S:ESS4:2:2.1 Recognize, and with assistance, safely demonstrate the use of tools to gather data and extend the senses, such as thermometers, hand lenses and balances.
