Activity Title: “Exploring Hydrocarbons: From Crude Oil to Everyday Materials”

Desired Outcome: I have explored how different materials can be derived from crude oil and their uses. I can explain the importance of carbon compounds in our lives.

Curriculum Area: Sciences

Level: Fourth Level

Introduction: In this activity, we will explore the world of hydrocarbons and how they are used to create everyday materials. We will learn about the different types of hydrocarbons found in crude oil and their uses in our daily lives. By the end of this activity, you will have a better understanding of the importance of carbon compounds in our lives.

Materials: - Crude oil sample - Glass beaker - Test tubes - Bunsen burner - Safety goggles - Plastic cups - Markers - Whiteboard and markers

Procedure:

1. Begin by introducing the concept of hydrocarbons and crude oil. Ask the students if they have heard of these terms before and what they know about them.

2. Show the students a sample of crude oil and explain that it is a mixture of different hydrocarbons.

3. Divide the class into small groups and give each group a glass beaker and a plastic cup. Instruct them to pour a small amount of crude oil into the beaker and observe its properties.

4. Ask the students to identify the different types of hydrocarbons found in crude oil. Explain that hydrocarbons are compounds made up of hydrogen and carbon atoms.

5. Using the test tubes and Bunsen burner, demonstrate how different hydrocarbons can be separated from crude oil through a process called fractional distillation.

6. Once the different hydrocarbons have been separated, ask the students to identify the uses of each type of hydrocarbon. For example, methane is used as a fuel for heating and cooking, while ethylene is used to make plastics.

7. Instruct the students to create a poster or presentation on the different types of hydrocarbons and their uses. They can use the plastic cups to create models of the different hydrocarbons.

8. As a class, discuss the importance of carbon compounds in our lives. Ask the students to identify other materials that are made from carbon compounds, such as clothing, medicines, and electronics.

9. Conclude the activity by reviewing the key concepts learned and the desired outcome.

Assessment: Assessment can be done through observation of the students’ participation in the activity and their understanding of the key concepts. The posters or presentations created by the students can also be used as a form of assessment.
