4.LS.1: Changes in an organism’s environment are sometimes beneficial to its survival and sometimes harmful.
4.LS.1.a: Ecosystems can change gradually or dramatically. When the environment changes, some plants and animals survive and reproduce and others die or move to new locations.
4.LS.1.b: Ecosystems are based on interrelationships among and between biotic and abiotic factors. These include the diversity of other organisms present, the availability of food and other resources, and the physical attributes of the environment.
4.PS.2: Energy can be transferred from one location to another or can be transformed from one form to another.
4.PS.2.a: Energy transfers from hot objects to cold objects as heat, resulting in a temperature change.
4.PS.2.b: Electric circuits require a complete loop of conducting materials through which electrical energy can be transferred.
4.PS.2.c: Electrical energy in circuits can be transformed to other forms of energy, including light, heat, sound and motion. Electricity and magnetism are closely related.
