Case 17 The Whisk

Introduction​

A whisk is a common kitchen tool that quickly and efficiently breaks up eggs and makes them fluffy and homogeneous. In this lesson, we will learn together how to make a fun whisk using the Nezha Inventor's Kit V2.

Teaching Objectives​

  • Learn about the basic principles and applications of egg beaters.
  • Learn how to use the Nezha Inventor's Kit V2 to create an automatically rotating whisk.
  • Design and build suitable mechanical structures to support the movement of the egg beater.
  • Develop teamwork, problem solving and creative thinking skills.

Teaching Preparations​

Nezha Inventor's Kit V2

Teaching Process​

Introduce​

Introduce students to the background and objectives of egg beater making to stimulate their interest and curiosity.

You must all have seen a whisk before! It is a tool used to mix ingredients and is especially useful when making cakes, pastry and other foods. Do you know how a whisk works? In today's lesson, we will explore the principle of a whisk together and make a whisk that rotates automatically using the Nezha Inventor's Kit V2.

Exploration​

Discuss in groups and ask students to think about how to make a whisk out of the building block materials.

  • How does the whisk make the egg mixture fluffy and even?
  • By what means do you think the whisk is rotated?

Practice​

Work in groups to create an egg beater from building blocks according to your own design.

Build an egg beater from blocks according to your own design.
