Exploring Separating Techniques

Introduction

In this Chemistry  WebQuest, students delve into the fascinating world of separating techniques through an interactive online journey. The quest unfolds as students navigate through a series of virtual laboratories and simulations, where they apply their knowledge of various methods such as filtration, evaporation and sublimation. Engaging multimedia resources and real-life scenarios challenge students to think critically about selecting the most appropriate technique for different mixtures. This web-based exploration not only enhances their understanding of scientific principles but also cultivates problem-solving skills essential for future scientific endeavors.

Task

At the end of this WebQuest students should be able to: 

  • Identify and recall separating techniques, including filtration, sublimation and evaporation 
  •  Explain the principles behind each separating technique and describe how they work in separating different mixtures.
  • Conduct a virtual experiment using the link provided 
  • Apply knowledge by selecting and justifying the choice of a specific separating technique for various mixtures in virtual scenarios.
  •  Analyze the effectiveness of each separating technique in the given scenarios.
  •  Evaluate the overall experience via peer discussion, reflecting on the choices made, challenges faced, and the broader implications of applying separating techniques to real-world situations.
Process

1. Access the following sources via the links below for the theoretical framework of filtration, sublimation and evaporation. Remember! document your notes. A short pencil is better than a long memory!!  

Read pages 10-13- https://chemguide.net/wp-content/uploads/2017/11/Separationtechniques_y9.pdf 

Watch the following videos and pay keen attention to the apparatuses used during the experiments:
