I set up Grefintec in 2012 and have successfully been making a wide variety of online teaching resources since then, primarily for the training of practitioners working within the early years and playwork sectors. However, my day job is a biology teacher so I also make resources for myself and these are the ones I share, for free, in my TES shop. I hope that you enjoy them and find them useful,

Organic Chemistry Functional Groups Guess Who?

Organic Chemistry Functional Groups Guess Who?

(1)
A Guess Who game designed for pupils revising Organic Chemistry functional groups. Inspired by the childhood game 'Guess Who?' and played in a similar way. Print out pages two copies of page 1 and print on the reverse page 2 so that when folded in half (as in the picture) the title page obscures the view of the functional groups. Print out two copies of page 3 and cut out the rectangles. Players face each other. Each player chooses a functional group and keeps it a secret. Players take it in turns to guess the identity of the other player's chosen group using clues associated with the different groups. Players use the white rectangles to cover the functional groups eliminated from the game. First player to guess the other player's functional group wins! Keywords: organic chemistry, functional groups, alkanes, alkenes, alcohols, aldehydes, ketones, carboxylic acids, esters, halogenalkanes, game. Guess Who?

Variation and Classification Crossword

(0)
Keywords linked to variation and classification. Developed for use with a Ks3 science class but could be used for GCSE. A great way to settle a class whilst consolidating learning of definitions linked to the topic.
Biology Catchphrase Game

Biology Catchphrase Game

(0)
This is a ten minute game which I created as a revision quiz for A-Level students revising semi-conservative DNA replication, although the board can be used for any biology topic, you just need to set the questions! You can either access the catchphrase board online at: http://www.grefintec.co.uk/catchphraseforbiology/story.html (copy and paste url to address bar) Or you can now download it for offline use from http://www.grefintec.co.uk/downloadslides.html (instruction on the site) Ask the first question to the class. The pupil who gets the question right, gets to choose a square to remove. This continues until either the questions are completed or the catchphrase is guessed. The winner is the person who can guess the biological catchphrase from the picture Just in case you can't work it out - the catchphrase is 'Survival of the fittest' Tip: Ask a pupil to be the game facilitator - enabling you to present the quiz. Enjoy!! Keywords: catchphrase, class game, biology, quick quiz, quiz, genetics, semi-conservative, DNA, DNA replication

Keywords for the Topic Solutions

(0)
Keystage 3 Resource A card sort where pupils are asked to match keywords with their definitions. Each central square has four keywords printed on each side. The definitions are on triangles which match up to the appropriate keyword. There are two sets of keywords, one in red and one in blue. They are also single or double bordered which means that the sets can still be identified when printed in greyscale. The card sort has been designed so that minimum cutting is required! Keywords: Solution, soluble, insoluble, saturated, dissolve, solubility, solvent, solute

Learning Outcomes/Objectives Slide Proforma Differentiated Using Bloom's Taxonomy

(0)
A Learning Outcomes/Objectives Slide proforma which can be added to your own lesson PowerPoint to show pupils which outcomes/objectives aim to be achieved during the lesson. Differentiated using Bloom's taxonomy enabling you to clearly show lower and higher level outcomes/objectives. Just adapt to your own requirements by deleting the boxes that you do not need - an example is given with three outcomes. Just type in the outcomes into the colour coordinated text box. Keywords: Bloom's taxonomy, knowledge, comprehension, application, analysis, evaluation, synthesis, lesson outcomes, lesson objectives, higher level, lower level, differentiation.

AfL: What I knew then...What I know now - A simple way to demonstrate progress.

(0)
Formative Assessment/Assessment for Learning 1. At the start of a new topic, get your pupils to stick this in on the first page. 2. Ask them to write everything that they already know about the topic in the centre square. 3. Then either mid way through the lesson, or mid way through the topic, turn back to this first page and ask the pupils to write everything that they know in the middle rectangle - using a different colour ink really highlights their new learning. Also at this point they can work as a 'talking pair' and expand on this. 4. At the end of the topic, return to this first page and complete the final rectangle, again using a different colour is a good idea, as is incorporating 'talking pair' information. A simple way to let both you and your students know what progress they have made.
Presenting Differentiated Lesson Tasks

Presenting Differentiated Lesson Tasks

(1)
A whole school PowerPoint slide to present differentiated lesson tasks. This differentiated task sheet enables students to take ownership for their own learning. The resource has been created using PowerPoint, this means that text boxes can be inserted onto the challenge levels to describe the tasks. I suggest two or three choices of task per challenge level. The challenge levels are indicated by spiciness, the spicier the task, the more challenging it is. Keywords: whole school, lesson, task sheet, worksheet, class template, chili, differentiated

Mini Plenary Cards (Biology Themed Back)

(0)
Mini plenaries are a type of formative assessment and are a great way to review progress of learning during a lesson. It also allows pupils opportunities for self reflection. "Teachers have also begun to be more flexible in introducing effective ‘mini plenaries’ at critical points in a lesson to review progress, clarify misunderstandings and move the work forward (OFSTED Dec. 2003)". Just ask a pupil to select a card and in so doing will feel like they are taking responsibility for their own learning. Just print out 9 copies of page 1 of the PDF and return to the printer for double sided printing and then print out pages 2-10. It is best to print out the cards on thick paper/thin card. I have laminated my set for durability. There are five sets available from my TES shop, the only difference is the back design, the actually mini plenary suggestions are the same. This is the biology themed back. Keywords: formative assessment, mini plenaries, plenary, assessment.

Ladybird Counting Tins Numbers 0-5 (early numeracy resource)

(0)
I created these tins for use in my former nursery where they were enjoyed by children aged 2.5 years to school age. On one side are the ladybirds with 0 - 5 spots and on the reverse the number is written. The tins were left on one of the radiators and the children accessed them when they chose. Sometimes I would find some very curious things in the counting boxes but more often than not the quantity would match the number of spots on the ladybird.

Whilst I do not claim that these are of the quality you would purchase from a science shop, they are certainly good enough for use in class. Obviously quality is also dependent upon your printer and please only print on printable OHP acetate film . If you use the incorrect type it can melt inside your printer and wreck it. Method Print out on printable transparency acetate film 24 micrometers per A4 sheet Cut out and use directly (no need to put on a slide) Each interval is 500um

Create a Simple Digital Microscope

(0)
Biologists use microscopes to see things that they can't see clearly with the naked eye. Microscopes are a fairly expensive piece of equipment and generally not very portable. In this practical you will convert smart phone/tablet to create a simple, portable digital microscope using cheap, easily accessible components. Then use it to explore and make observations about the microscopic details of everyday things.
