Did you know that dinosaurs might have drunk the same water we drink today?<br />
The water that we have never goes away and new water is never created. You might say the water we use is recycled!<br />
Water changes form as it moves through the water cycle. <br />
TEKs 2nd Grade Science<br /> 112.4. Science, Grade 2.<br /> <br />(4) A system is a collection of cycles, structures, and processes that interact. Students should understand a whole in terms of its components and how these components relate to each other and to the whole. All systems have basic properties that can be described in terms of space, time, energy, and matter. Change and constancy occur in systems and can be observed and measured as patterns. These patterns help to predict what will happen next and can change over time.<br /> <br /> <br />(1) Scientific processes. The student conducts classroom and field investigations following home and school safety procedures. The student is expected to:<br /> (A) demonstrate safe practices during classroom and field investigations; and<br /> (B) learn how to use and conserve resources and dispose of materials.<br /> (2) Scientific processes. The student develops abilities necessary to do scientific inquiry in the field and the classroom. The student is expected to:<br /> (B) plan and conduct simple descriptive investigations;<br /> (C) compare results of investigations with what students and scientists know about the world;<br /> <br /> <br />(7) Science concepts. The student knows that many types of change occur. The student is expected to:<br /> (A) observe, measure, record, analyze, predict, and illustrate changes in size, mass, temperature, color, position, quantity, sound, and movement;<br /> (B) identify, predict, and test uses of heat to cause change such as melting and evaporation;<br /> <br /> <br />(10) Science concepts. The student knows that the natural world includes rocks, soil, water, and gases of the atmosphere. The student is expected to:<br /> (A) describe and illustrate the water cycle; <br /> (B) identify uses of natural resources.<br /> <br /> <br />
