1st Lab Session Week
Concept: 3
Rocks-Physical properties of rocks
Investigation: Are all
rocks the same?
Wonders READING: pg. 66-71 Rocks
CA Science Standards
3. Earth is made of materials that have distinct properties and
provide resources for human activities. As a basis for understanding this
concept:
3a. Students know how to compare the physical properties of
different kinds of rocks and know that rock is composed of different
combinations of minerals.
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:
4f. Use magnifiers or microscopes to observe and draw
descriptions of small objects or small features of objects.
2nd Lab Session Week
Concept: Sorting rocks
by physical properties
Investigation: What
are river rocks?
Wonders READING: pg. 72-77 Changing Rocks
CA Science Standards
3a. Students know how to compare the physical properties of
different kinds of rocks and know that rock is composed of different
combinations of minerals.
4c. Compare and sort common objects according to two or more
physical attributes (e.g., color, shape, texture, size, weight).
4d. Write or draw descriptions of a sequence of steps, events,
and observations.
4f. Use magnifiers or microscopes to observe and draw
descriptions of small objects or small features of objects.
3rd Lab Session Week
Concept: Screening
river rocks
Investigation: How do
rocks get smaller?
NO Wonders READING
CA Science Standards
3a. Students know how to compare the physical properties of
different kinds of rocks and know that rock is composed of different
combinations of minerals.
3b. Students know smaller rocks come from the breakage and
weathering of larger rocks.
4c. Compare and sort common objects according to two or more
physical attributes (e.g., color, shape, texture, size, weight).
4d. Write or draw descriptions of a sequence of steps, events,
and observations.
4f. Use magnifiers or microscopes to observe and draw
descriptions of small objects or small features of objects.
4g. Follow oral instructions for a scientific investigation.
4th Lab Session Week
Concept: Measuring
rocks
Investigation: How do
scientist measure rocks?
NO Wonders READING
CA Science Standards
3a. Students know how to compare the physical properties of
different kinds of rocks and know that rock is composed of different
combinations of minerals.
4b. Measure length, weight, temperature, and liquid volume with
appropriate tools and express those measurements in standard metric system
units.
5th Lab Session Week
Concept: Different uses of rocks
Investigation: How are rocks used?
Wonders READING: pg. 90-95 Natural Resources
CA Science Standards
3e. Students know rock, water, plants, and soil provide many resources, including food, fuel, and building materials, that humans use.
6th Lab Session Week
Concept: Fossils
Investigation: How can we learn from fossils?
Wonders READING: pg. 84-89 Fossils
CA Science Standards
3d. 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.
7th Lab Session Week
Concept: Sand, soil,
clay silt exploration
Investigation: What is
soil made of?
Wonders READING: pg. 78-83 Soil
CA Science Standards
3c. 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.
4f. Use magnifiers or microscopes to observe and draw
descriptions of small objects or small features of objects.
Subject to change.
