*Matter has properties that can be observed through the senses.

*Objects have properties that can observed, described, and/or measured.

*Objects and or materials can be sorted or classified according to their properties.

*Matter takes up space and has mass. Two objects cannot occupy the same place at the same time.

Energy





Key Ideas: Energy exists in many forms: heat, electric, sound, chemical, mechanical, light. Temperature can affect the state of matter of a substance. Changes in the properties of materials/objects can be observed and described. Some materials transfer energy better than others. Energy can be transferred from one place to another. Heat can be released in many ways. For example, by burning, friction, or combining one substance with another. Interactions with forms of energy can be either helpful or harmful. Everyday events involve one form of energy being changed to another. Vocabulary: appliance conduction conductor electricity energy forces freezing friction gas heat insulator light liquid observation melting motion property sound temperature water cycle

Living Things:Animals





Key Ideas: Living things are both similiar to and different from each other and from nonliving things. Animals change depending on their environment. Animals are grouped into different categories. Animals adapt to survive in their habitats. Animals change their environment to better meet their needs. Life cycle of a ladybug Vocabulary: adapt adaptations alive amphibians arthropods camouflage desert environment habitat hibernation migration organism polar rain forest survival wetland woodland

Living Things:Plants





Key Ideas: Create a biome in a container. Parts and functions of plants Photosynthesis Life Cycle of a Plant Vocabulary: biome by-product carbon dioxide condensation evaporation glucose oxygen photosynthesis precipitation roots sprout water cycle
