CA.ES. Earth Sciences
ES.3. Earth is made of materials that have distinct properties and provide resources for human activities. As a basis for understanding this concept:
ES.3.a. Students know how to compare the physical properties of different kinds of rocks and know that rock is composed of different combinations of minerals.
ES.3.b. Students know smaller rocks come from the breakage and weathering of larger rocks.
ES.3.c. Students know that soil is made partly from weathered rock and partly from organic materials and that soils differ in their color, texture, capacity to retain water, and ability to support the growth of many kinds of plants.
ES.3.d. Students know that fossils provide evidence about the plants and animals that lived long ago and that scientists learn about the past history of Earth by studying fossils.
ES.3.e. Students know rock, water, plants, and soil provide many resources, including food, fuel, and building materials, that humans use.
CA.IE. Investigation and Experimentation
IE.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:
IE.4.a. Make predictions based on observed patterns and not random guessing.
IE.4.b. Measure length, weight, temperature, and liquid volume with appropriate tools and express those measurements in standard metric system units.
IE.4.c. Compare and sort common objects according to two or more physical attributes (e.g., color, shape, texture, size, weight).
IE.4.d. Write or draw descriptions of a sequence of steps, events, and observations.
IE.4.e. Construct bar graphs to record data, using appropriately labeled axes.
IE.4.f. Use magnifiers or microscopes to observe and draw descriptions of small objects or small features of objects.
CA.LS. Life Sciences
LS.2. Plants and animals have predictable life cycles. As a basis for understanding this concept:
LS.2.a. Students know that organisms reproduce offspring of their own kind and that the offspring resemble their parents and one another.
LS.2.b. Students know the sequential stages of life cycles are different for different animals, such as butterflies, frogs, and mice.
LS.2.e. Students know light, gravity, touch, or environmental stress can affect the germination, growth, and development of plants.
LS.2.f. Students know flowers and fruits are associated with reproduction in plants.
CA.PS. Physical Sciences
PS.1. The motion of objects can be observed and measured. As a basis for understanding this concept:
PS.1.d. Students know tools and machines are used to apply pushes and pulls (forces) to make things move.
PS.1.e. Students know objects fall to the ground unless something holds them up.
PS.1.f. Students know magnets can be used to make some objects move without being touched.
PS.1.g. Students know sound is made by vibrating objects and can be described by its pitch and volume.
