Practise ws for drawing structural and displayed formulae for a variety of organic compounds.

This is a chemistry lesson on chemical reactions.The Excel spreadsheet contains a student worksheet, technician’s notes and full teacher’s notes all on separate sheets within the spreadsheet. The powerpoint has 3 slides. Slide 1 is a learning framework for the lesson. Slide 2 is a visual aid for the starter. ( Any ‘naughty kids in a lab’ type worksheet you may have could be used here if you prefer.) Slide 3 is a group of words that you can leave on screen whilst the practical is being done so that students have spellings of words they might need to complete their worksheet.

Early in Yr 7 .

I wrote this worksheet for a KS3 Chemistry lesson on particles. It is a standard dilutions practical. I wanted to see if my students could follow written instructions without any demonstration. We had done several lessons on particles, so they had enough science in order to be able to explain what was happening. You need a concentrated solution of potassium permanganate for this experiment rather than crystals. Explain what you are doing with it and your lab. tech. should be able to supply an appropriate quantity and concentration. The final dilution should be barely observable. Remember that each group only needs 1ml so the total amount for a class will only be in one small beaker. You need to do your own risk assessment but remember eye protection must be worn. Tip: you will find it easier to control if students use 1ml pipettes instead of the standard 3ml. Another tip: keep the concentrated solution with you at the front with one pipette. If each group sends a student to you with an empty test tube you can ensure that it is measured accurately. They then take theirs back to their bench and add 9ml water to it for their first dilution.

Visual aid to teaching about safety at the start yr7. Includes the new hazard symbols.

Useful intoduction to Periodic table and how it fits together. Two versions on separate sheets within spreadsheet; first 10 elements; first 20 elements. Print landscape. Carefully cut into 3 strips. One per student to stick inside cover of exercise book.

Watch video (find on YouTube) whilst answering questions. Approx. 20 mins video. Can be answered on the sheet with (mostly) single word answers.

This needs printing and cutting up ahead of the lesson because the sentences are correctly matched on the sheet. If done on thin card they can be used again and again. Try printing each sheet on a different colour card. That way if one card left over you can easily pair it up with its correct pack. Also 2 students sitting together can have different colour packs without them getting cards mixed up.

Table and graph axes to support lower ability students with recording data from the practical identified on the table.

I did this in Excel as it was an easy way to keep the worksheet and answer sheet together. Could be used as a framework for a research activity.

Worksheet to record and see the difference between structural and displayed formulae.

Table to record results of tests of various organic compounds during a practical lesson. Then make predictions using the data collected.

Print onto a sheet of 4 labels. Stick inside cover of exercise books. Alternatively print onto paper, cut and glue.

Useful for keeping track of which chemicals you have put in a dimple tray. Have a supply to hand. Also good for drawing what was seen down a microscope for a series of slides.

Print onto A4, chop in half to A5. Keep a supply for pupils who just can’t draw a test tube.

Useful for less able students who struggle to draw axes and identify where to put the numbers. Don’t be put off by the formatting on the preview, it downloads and prints off fine.
