Grefintec's Shop

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,

Data Analysis - Graph Plotting Skills

I have created this worksheet to support A-Levels students to plot data accurately, but could easily be used with GCSE students. I deliver it as part of a lesson, prior to them doing a practical where they are required to demonstrate this as a skill. The data looks at the effect of temperature on the growth of * Onchorynchus mykiss* (Rainbow trout).

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

The Twelve Days of Science (Festive Homework)

Encourage independent learning with this 'Twelve Days of Christmas' template. Simply add text to the (bacteria/virus) baubles and ask your students to choose what they want to do. How you deliver this is entirely up to you. For example you could ask them to do a minimum of two home works. In order to position the text boxes over the baubles I have just used the number '1'. This means that they can be easily edited and personalised by you. #festive; #Christmas; #independent learning #homework
Analogy: Effect of Non-Competitive and Competitive Inhibitors on the Rate of Reaction

Analogy: Effect of Non-Competitive and Competitive Inhibitors on the Rate of Reaction

(0)
Analogy for Competitive and Non- Competitive Enzyme Inhibition Rate Graph Situation: Preschool birthday party game of musical chairs. The preschoolers are the substrate, the chairs are the enzymes, dads are competitive inhibitors and siblings are non-competitive inhibitors. Competitive Inhibition Some of the parent’s want to play. But the more parents there are the less likely the preschoolers are going to get a seat when the music stops. Eventually there will be a point when they are out competed for the seats because there are so many parents playing Non Competitive Inhibition The preschoolers have older siblings who are too cool to be at a party like this. When the music starts they run around pushing the chairs over so they can’t be used in the game anymore. It doesn’t matter how many preschoolers there are, they can’t ever fill all of the chairs because some are out of action.

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.
