Standards for Teaching and Learning
5.3.1: Describe the Earth as part of a system called the solar system that includes the sun (a star), planets, comets, asteroids, and many moons.
5.3.2: Recognize that the Earth is the third planet from the sun in our solar system.
5.3.4: Describe that, like all planets and stars, the Earth is approximately spherical in shape.
5.3.5: Explain that the alternation between day and night and the apparent movement of the sun, moon, and stars across the sky depend on the rotation of the Earth on its axis.
5.4.1: Investigate and describe when liquid water evaporates, it turns into a gas (vapor) mixed into the air and can condense and reappear as a liquid when cooled or as a solid (ice) if cooled below the freezing point of water.
5.5.1: Recognize that all matter is made of small particles called atoms, which are too small to see with our eyes; describe how atoms may combine to form molecules or crystalline solids (compounds).
5.5.4: Investigate and describe that heating and cooling cause changes in the properties of substances. For example, liquid water can turn into steam by boiling, and water can turn into ice by freezing.
5.5.6: Explain that when a warm object and a cool one are placed in contact, heat flows from the warmer object to the cooler one until they are both at the same temperature. Know heat transfer can also occur at a distance by radiation.
5.5.7: Investigate and describe that some materials conduct heat much better than others, and poor conductors (insulators) can be used to reduce heat loss or gain.
5.6.1: Explain that objects can move with a very wide range of speeds, with some moving very slowly and some moving too quickly for people to see them.
5.6.2: Demonstrate that if the forces acting on an object are balanced so that the net force is zero, the object will remain at rest if it is initially at rest or will maintain constant speed and direction if it is initially moving.
5.6.3: Investigate and describe that unbalanced forces cause changes in the speed and/or direction of motion of an object (acceleration).
5.6.4: Describe that, for an object moving in a straight line, acceleration a is the change in velocity, v divided by the time t that change takes (a = v Ö t).
5.6.5: Investigate and describe that the greater the net force F applied to a body, the greater its acceleration a. Describe that the greater the mass m of an object, the smaller the acceleration produced by a given force.
5.7.1: Observe and describe that some organisms consist of a single cell which needs an environment that can supply food, water, sometimes oxygen, and a way to dispose of waste. (Some single-celled organisms are anaerobes.)
5.8.1: Explain why there must be a reliable way to transfer information from one generation to the next in order for offspring to resemble their parents.
5.8.2: List some characteristics of plants and animals that are fully inherited (e.g., form of flower, shape of leaves) and others that are affected by the climate or environmental conditions (e.g., browning of leaves from too much sun, language spoken).
5.9.1: Explain that in any particular environment, some kinds of plants and animals survive well, some do not survive as well, and some cannot survive at all.
5.9.2: Identify organisms that are not native to the Washington, D.C. area and how they undergo changes to increase their chance of survival in the area.
5.9.3: Explain how organisms can cause changes in their environment to ensure survival, and these changes may affect the ecosystem (the living and non-living components of the environment).
5.9.6: Explain that many plants and animals can survive harsh environments because of seasonal behaviors (e.g., in winter, some trees shed leaves, some animals hibernate).
5.9.8: Describe well-defined plant behaviors, such as the way seedlings' stems grow toward light and their roots grow downward in response to gravity.
