3. Physical Sciences  1. Materials come in different forms (states), including solids, liquids, and gases. As a basis for understanding this concept:  1. Students know solids, liquids, and gases have different properties.  2. Students know the properties of substances can change when the substances are mixed, cooled, or heated.  1.

4. Life Sciences  2. Plants and animals meet their needs in different ways. As a basis for understanding this concept:  1. Students know different plants and animals inhabit different kinds of environments and have external features that help them thrive in different kinds of places.  2. Students know both plants and animals need water, animals need food, and plants need light.  3. Students know animals eat plants or other animals for food and may also use plants or even other animals for shelter and nesting.  4. Students know how to infer what animals eat from the shapes of their teeth (e.g., sharp teeth: eats meat; flat teeth: eats plants).  5. Students know roots are associated with the intake of water and soil nutrients and green leaves are associated with making food from sunlight.  2.

5. Earth Sciences  3. Weather can be observed, measured, and described. As a basis for understanding this concept:  1. Students know how to use simple tools (e.g., thermometer, wind vane) to measure weather conditions and record changes from day to day and across the seasons.  2. Students know that the weather changes from day to day but that trends in temperature or of rain (or snow) tend to be predictable during a season.  3. Students know the sun warms the land, air, and water.  3. Weather can be observed, measured, and described. As a basis for understanding this concept:  1.

6. Investigation and Experimentation  4. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will:  1. Draw pictures that portray some features of the thing being described.  2. Record observations and data with pictures, numbers, or written statements.  3. Record observations on a bar graph.  4. Describe the relative position of objects by using two references (e.g., above and next to, below and left of).  5. Make new observations when discrepancies exist between two descriptions of the same object or phenomenon.  4.

7. Experiment with Solid, Gas & Liquid  One Idea is to have students observe and interact with dry ice and regular ice. Student will observe as ice melts and dry ice disappears.

8. Experiment with growing plants Experiment with growing plants  Put plant seeds in a moist paper towel. Fold the paper towel so that the seed is completely enclosed. Put the seed in a sealed sandwich bag. In one or two week check the bags. The seed will have sprouted.

9. Experiment with the sun  Put a thermometer in the shade and one in direct sun light. Record the temperature at the beginning and half an hour later.

10. Experiment with Observation  Students make leaf rubbings using different leaves from several different trees. Student record the size and shapes of the leaves. Discuss vein patterns and have students report on statistical data.
