Molar Mass by Freezing Point Depression Lab Experiment, Boiling Point Elevation, Molality Lesson

Molar Mass by Freezing Point Depression Lab Experiment, Boiling Point Elevation, Molality Lesson

This 33-slide PowerPoint presentation introduces students to the concept of freezing point depression and boiling point elevation. It also includes a worksheet in which students can take notes and practice the skills learned during the lesson. • First, students will review what happens when a liquid freezes and when it boils. • Then, a discussion about how adding a nonvolatile solute would affect the freezing and boiling process. • Molality will be introduced followed by practice problems. • The freezing point depression and boiling point elevation formulas will be introduced with examples for students to work out. • Finally, a practical investigation to work out the molar mass of an unknown solute by using freezing point depression will be outlined with an example calculation. I hope you find this useful.

Topic 10 (AQA) GCSE new spec  3 (differentiated) worksheets for materials and their properties

Topic 10 (AQA) GCSE new spec 3 (differentiated) worksheets for materials and their properties

Based on the AQA triple course, but will work for other boards (AQA and Edexcel references included). The students have to complete a table about the production, properties , uses and examples of composites, alloys, polymers and ceramics. They then need to decide on which properties make a material suitable to particular jobs. good for: part of a lesson, homework, catch up sheet for absent students, cover, part of an independent project if lesson time is short. differentiation: 3 levels of difficulty, the easiest is suggested for foundation triple students, but could also be an easier worksheet again for higher students. The foundation sheet could be used for KS3 Suggested answers included in a separate document

The Greenhouse Effect

The Greenhouse Effect

This lesson is run as a competition between small groups of students. The lesson encourages students to use a series of challenges and clues to work out for themselves the key ideas about the greenhouse effect. The lesson is structured with a starter, a session gathering the main ideas and then time for students to put together their own explanation. It is aimed at less academic GCSE students but would also work well for keystage 3 students and more able GCSE students who could complete it more quickly.

Haloalkanes and the Ozone Layer AS Chemistry OCR

Haloalkanes and the Ozone Layer AS Chemistry OCR

A lesson covering haloalkanes and the ozone layer designed for the OCR AS chemistry specification. The lesson goes why the ozone layer is important, what CFCs are and their uses and the free radical reactions between CFCs and NO and ozone. The presentation contains questions (and answers) for students to work through on slides, so no printing is needed.

GCSE Chemistry Xmas QUIZ

GCSE Chemistry Xmas QUIZ

This lesson presentation (29 slides) and associated worksheet consists of a series of 5 fun quiz rounds which will engage your students at the end of this long term whilst subtly testing their GCSE Chemistry knowledge. A range of knowledge from across the GCSE specification is tested in rounds such as "The 12 days of Chemistry Xmas" and "Crack the Advent Calendar Code".

The Carbon Cycle (Lesson Observation)

The Carbon Cycle (Lesson Observation)

The Carbon Cycle. A KS3 / KS4 lesson designed on building and then writing about the carbon cycle. Written for a lesson observation and designed for independent learning. A starter task for students to write what they already know about the carbon cycle. You tube video's included. A3 build your own carbon cycle group task with levelled task cards and key words. Students then complete independent choice of task (templates included) to be peer assessed. Peer assessment sheet included. Key words for SEN students SMSC questions Literacy tasks
