 * (4) Scientific investigation and reasoning. The student knows how to use a variety of tools and methods to conduct science inquiry. The student is expected to:**

Brainpop Jr. []

(B) use safety equipment as appropriate, including safety goggles and gloves.


 * (5) Matter and energy. The student knows that matter has measurable physical properties and those properties determine how matter is classified, changed, and used. The student is expected to:**

(A) measure, test, and record physical properties of matter, including temperature, mass, magnetism, and the ability to sink or float; Brain Pop Jr. "Forces" []

(B) describe and classify samples of matter as solids, liquids, and gases and demonstrate that solids have a definite shape and that liquids and gases take the shape of their container; Brain Pop Jr. "Matter" [|http://www.brainpopjr.com/science/matter/][|__http://__] Brain Pop Jr. "Activity solids, Liquids and Gas" __www.brainpopjr.com/science/matter/solidsliquidsandgases/activity/__

(C) predict, observe, and record changes in the state of matter caused by heating or cooling; and Brain Pop Jr. "Heat Activity" [] Brain Pop Jr. "Changing States of Matter" []

(D) explore and recognize that a mixture is created when two materials are combined such as gravel and sand and metal and plastic paper clips.

(A) explore different forms of energy, including mechanical, light, sound, and heat/thermal in everyday life; Brain pop Jr. " Energy"[]
 * (6) Force, motion, and energy. The student knows that forces cause change and that energy exists in many forms. The student is expected to:**

(B) demonstrate and observe how position and motion can be changed by pushing and pulling objects to show work being done such as swings, balls, pulleys, and wagons; and Brain Pop Jr. "Pushes and Pulls"[]

(C) observe forces such as magnetism and gravity acting on objects. Brain Pop jr. "Magnets" []

(A) explore and record how soils are formed by weathering of rock and the decomposition of plant and animal remains;
 * (7) Earth and space. The student knows that Earth consists of natural resources and its surface is constantly changing. The student is expected to:**

(B) investigate rapid changes in Earth's surface such as volcanic eruptions, earthquakes, and landslides; []

(C) identify and compare different landforms, including mountains, hills, valleys, and plains; and []

(D) explore the characteristics of natural resources that make them useful in products and materials such as clothing and furniture and how resources may be conserved. []

(A) observe, measure, record, and compare day-to-day weather changes in different locations at the same time that include air temperature, wind direction, and precipitation; []
 * (8) Earth and space. The student knows there are recognizable patterns in the natural world and among objects in the sky. The student is expected to:**

(B) describe and illustrate the Sun as a star composed of gases that provides light and heat energy for the water cycle; [] []

(C) construct models that demonstrate the relationship of the Sun, Earth, and Moon, including orbits and positions; and []

(D) identify the planets in Earth's solar system and their position in relation to the Sun.

(A) observe and describe the physical characteristics of environments and how they support populations and communities within an ecosystem; []
 * (9) Organisms and environments. The student knows that organisms have characteristics that help them survive and can describe patterns, cycles, systems, and relationships within the environments. The student is expected to:**

(B) identify and describe the flow of energy in a food chain and predict how changes in a food chain affect the ecosystem such as removal of frogs from a pond or bees from a field; and []

(C) describe environmental changes such as floods and droughts where some organisms thrive and others perish or move to new environments

(A) explore how structures and functions of plants and animals allow them to survive in a particular environment; [] []
 * (10) Organisms and environments. The student knows that organisms undergo similar life processes and have structures that help them survive within their environments. The student is expected to:**

(B) explore that some characteristics of organisms are inherited such as the number of limbs on an animal or flower color and recognize that some behaviors are learned in response to living in a certain environment such as animals using tools to get food; and
