WEBQUEST NITROGEN AND ITS COMPOUNDS FORM 3 SUBJECT

WEBQUEST NITROGEN AND ITS COMPOUNDS FORM: 3 SUBJECT: CHEMISTRY TOPIC: NITROGEN AND ITS COMPOUNDS WEBQUEST OBJECTIVES: Provide Students with opportunities to work together in collaborative teams and peer teach one another while carrying out an assignment on Nitrogen and its compounds. WEBQUEST TEAMS: 1. 2. 3. 4. 5. Nitrogen as an element Oxides of nitrogen Ammonia Nitric(v) acid Nitrates , Pollution effect of nitrogen and its compounds and reduction of environmental pollution. • • Nitrogen, 7 N General properties Appearance colorless gas, liquid or solid

Introduction Look at our sorrounding, air is a component.

• Air consist of several components: Nitrogen Oxygen Carbon(iv) oxide Noble gases Dust particles Water vapour

Introduction What is nitrogen? How is nitrogen isolated from air? How is nitrogen prepared in the laboratory? What are the compounds of nitrogen , their preparation, physical and chemical properties • Nitrates, Pollution effect of nitrogen and its compounds and reducing environmental pollution. • •

Tasks • You will be divided into 5 groups labeled. 1. 2. 3. 4. 5. Nitrogen Oxides of nitrogen Ammonia Nitric(v) acid Nitrates, Pollution effect of nitrogen and its compounds and reducing environmental pollution.

• In your groups you will research on what has been assigned to your group under the following key areas • Preparation • The physical and chemical properties of the compounds of nitrogen • Effect of heat on nitrates • Pollution effects and prevention

Tasks • Your will work collaboratively to do research from the internet, text books and conduct experiments in the laboratory. • The results of your inquiry will be presented using MS Power. Point and MS Word to the class. • Your work will be evaluated and shared to the rest of the members of the class. • The best team will get a whole a loaf each.

Resources-ICT • • Desktop computers MS office suite. Camera Internet. simulations Weblinks. Projectors

Resources –Non ICT • Course books- Longman Explore Chemistry book 3 pages 186 -248 • KLB chemistry book 3 pages 119 -159 • Your note books. • Apparatus and chemicals in the laboratory.

Guidance • From the above web linkages extract and compile information into Slides. • With the assistance of the teacher and the lab technician carry out experiments to determine the chemical properties of nitrogen and its compounds.

Conclusion and reflection Its my believe that if you immerse yourself in the tasks ahead learning will be more enjoyable and result to deeper understanding of various concepts through the interaction with technology and fellow students. The presentation of group work will provide you with an opportunity to show case your efforts and teach your peers in a new way
