Create a 20 mark activity that tests learner's ability to synthesis and evaluate, a memo must be included.

Question

Under the topic of solid materials(raw and manufactured materials) grade 4. Create an activity with 10 questions

Answer 1

Activity: Synthesis and Evaluation of Solid Materials

Objective: To test learners' ability to synthesize and evaluate information related to solid materials, both raw and manufactured.

Instructions: Read the following memo carefully and answer the questions that follow.

Memo:
Subject: Solid Materials Assessment
To: Grade 4 Students
From: Science Teacher

Dear Students,

As part of our unit on solid materials, you will be given a series of questions to test your understanding of raw and manufactured materials. Please read each question carefully and provide thoughtful responses based on the knowledge you have gained in class.

Good luck!

1. What is the difference between raw materials and manufactured materials?

2. Give an example of a raw material and explain how it is used in everyday life.

3. Describe the process of manufacturing a plastic toy from raw materials.

4. Why is it important to recycle materials instead of throwing them away?

5. How do properties of materials influence their uses?

6. Find three examples of everyday objects made from different types of materials and explain why that material was chosen for each object.

7. Compare and contrast the properties of wood and metal. Which material would be better for building a sturdy bridge and why?

8. How do manufacturers decide which materials to use in creating new products?

9. Discuss the environmental impact of extracting raw materials versus recycling existing materials.

10. Imagine you are a scientist tasked with finding a new material to replace plastic in food packaging. What properties would you prioritize in your search for this new material?

Scoring:
Each question is worth 2 marks, for a total of 20 marks. Responses will be evaluated based on the clarity of explanation, use of examples, and understanding of the properties and uses of solid materials.

Best of luck with the assessment!

Sincerely,
Science Teacher

Note: This activity can be adjusted and modified to suit the specific needs and abilities of grade 4 students. Additional resources, such as visuals or hands-on experiments, can be incorporated to enhance the learning experience.
