Level 3 Module 1

Lesson 3 Extension | Earth Changes

Working in groups, students observe layers and compare different components of soil.

PREPARATION

For the soil column, provide students with a large clean jar with a tight-fitting lid, soil, water, dish

soap, and a teaspoon. Provide each group with samples of sand, silt, and clay for students to compare with the components in the soil column.

Distribute and read aloud the following procedure sheet to students.

Observe Soil

1. Add soil to the jar until the jar is half full. Break up any large clumps.

2. Add water to the jar until the jar is full.

3. Add 1 teaspoon of dish soap to the jar.

4. Use the lid to close the jar tightly.

5. Shake the jar to mix the soil and water.

6. Set down the jar, and then observe it for 1 minute.

7. Draw what you observe after 1 minute.

8. Observe the jar again 1 day later. Draw what you observe.

9. Compare the samples of sand, silt, and clay with the components in the soil column. Describe what you notice.

10. Compare your observations of the jar after 1 minute and after 1 day. Describe any changes you noticed.

11. Share your findings with the class.

Lesson 8 Extension | Earth Changes

Working individually or in groups, students use stickers to mark locations on an inflatable globe where water and land interact on Earth.

PREPARATION

Provide students with stickers and an inflatable globe.

Distribute and read aloud the following procedure sheet to students.

Identify Water and Land Interactions

1. Think about places where you have seen water and land interact.

2. Find places on the inflatable globe where water and land interact.

3. Place a sticker on the inflatable globe at each place where water and land interact.

4. Share and compare your findings with another group.

Lesson 15 Extension | Earth Changes

Working individually or in groups, students research natural resources used to make common materials.

PREPARATION

As necessary, curate resources for student research. Provide students with access to research materials and sticky notes.

Distribute and read aloud the following procedure sheet to students.

Research

Natural Resources

1. Read the list of materials in the chart. Research which natural resources are used to make each material.

2. Record your findings on the chart.

Material

Natural Resources Used to Make the Material

3. On a sticky note, write the name of each natural resource.

4. Find one classroom object made from each natural resource. Place the matching sticky note on each object.

5. Share your findings with the class.

Lesson 23 Extension | Earth Changes

Working individually or in groups, students choose an unanswered question or related phenomenon from the module to research or investigate. Students then present their findings to the class.

PREPARATION

Prepare a list of unanswered questions and related phenomena from the module

driving question board. As necessary, curate resources for student research or provide materials for teacher-approved investigations. Consider allowing students to bring materials from home. Prepare to review safety measures with students as necessary.

Distribute and read aloud the appropriate procedure sheet to students.

Research a Science Topic

1. Choose an unanswered question or phenomenon.

2. Research the topic.

3. Prepare a presentation that answers the question or explains the phenomenon.

4. Present your findings to the class.

Carry Out an Investigation

1. Choose an unanswered question or phenomenon.

2. Design an investigation to answer the question or explore the phenomenon. Your teacher must approve the investigation.

3. Carry out your investigation. Follow all safety measures your teacher reviews with you.

4. Present your findings to the class.

Working individually or in groups, students research recycling in their community.

PREPARATION

As necessary, curate resources for student research. Provide students with access to research materials.

Distribute and read aloud the following procedure sheet to students.

Research Recycling in Your Community

1. Research your community’s recycling processes.

2. Record your answers to the questions in the chart.

Where is your community’s recycling center?

What types of materials are recycled there?

What happens to the materials after they are recycled?

3. Share your findings with another group.

Lesson 3 Extension | Changes in Matter

Working in pairs or groups, students explore how objects or materials change during heating.

PREPARATION

Provide students with safety goggles, heat-resistant gloves, a heat source (e.g., hair dryer, heat lamp, microwave), and containers and objects or materials that can be safely heated

(e.g., butter, chocolate chips). This investigation poses potential hazards. Review safety measures with students, including wearing safety goggles and heat-resistant gloves throughout the activity and handling the heated objects or materials with care. Supervise student investigations.

Distribute and read aloud the following procedure sheet to students.

Investigate Heating

1. Choose one object or material from the list provided by your teacher. Record the object or material you chose:

2. Create a procedure to investigate what happens to the object or material when it is heated. Write the steps in your procedure.

3. Ask your teacher to review your investigation.

4. After your teacher approves your procedure, conduct your investigation. Follow all safety measures your teacher reviews with you.

5. Present your findings to the class.
