The Periodic Table- Basic Information

The Periodic Table- Basic Information

These 4 worksheets are intended for very low ability students. The first page is a very simple text outlining an aspect of the Periodic Table. The second page of each worksheet is a simple comprehension task, and a sentence matching task. All sheets have the same format so students can become used to what they are expected to do. The sheets are intended as a starter to revise work previously covered before moving on to new content. The answers are included on the student sheet, to be cut off and stuck in to save students writing corrections, or to allow students who are ill to have the answers. Students can also be given the answers to self-mark work.

pH, Indicators, Neutralisation and Salts

pH, Indicators, Neutralisation and Salts

This group of resources is "hands-on and brains-on" Start the lesson with the practical work making a rainbow. This can be done as a teacher demonstration but is lovely for students to carry out. Follow up with the "colouring in" worksheet that takes a look at different indicators. There is a kinesthetic activity designed to get students moving and help them think about which acids and alkalis are needed to make a series of salts. To finish off students can work through the neutralisation worksheet which involves more thinking and colouring in.

for KS3 or GCSE: naming the elements in compounds differentiated  worksheet

for KS3 or GCSE: naming the elements in compounds differentiated worksheet

the students have to state which elements and how many atoms of each at in the compound. there are 15 examples for them to try, getting progressively harder differentiation is at 3 levels: easier as described above, middle: the students attempt to name the compounds given the formulae as well as above; and harder: the students attempt to produce the formulae, given the name of the compound as well as above SUGGESTION: for KS3 - give only the first 10 examples ideas for use: I used as a homework, but also: part of your lesson; cover; catch up for absent students Answers included

9 Christmas songs for starter activities for physics, biology and Chemistry

9 Christmas songs for starter activities for physics, biology and Chemistry

3 for each science. Songs that I have used for starter activities so the students to then either write their own Christmas song (KS3) or to write quiz questions on the topic (with a Christmas theme) to test their fellow students at the end of the lesson. Each song has 2 activities where the students have to sing the missing words (if they don't want to sing the whole thing) and each song has some check questions. objective: subject knowledge differentiation: all songs differentiated to at least 2 levels of difficulty; physics calculation questions come with 2 levels of hint there is a recording of each song embedded in the slides - please excuse my singing and feel free to delete this part
