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.

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

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

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.

Storyboard: What happens when bacteria enter your body?

(0)
Pupils are asked to complete a storyboard to illustrate what happens when a bacteria enters their body. The process starts from the moment 'Toby' gets scratched by his cat. His blood begins to clot then the immune system uses phagocytes and lymphocytes to target the bacteria. Key words: Y shaped molecules, antibodies, phagocyte, phagocytosis, lymphocyte, agglutination, immune system, bacteria, storyboard

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
Memory/Snap Game Using Shape and Colour

Memory/Snap Game Using Shape and Colour

(0)
I work as an SEN assistant and am employed to work one-to-one with a three year old child who has global developmental delay. Whilst she has very limited verbal communication, I have discovered that she is great at playing memory and enjoys playing the game. We have been focusing more recently on colour and shape so I have created this memory game to specifically support her learning. The game consists of 32 colour cards. The shapes are square, circle, triangle and star printed in pairs in each of four colours: red, blue, yellow and green. I do not play the game using all 32 cards and currently use either all of one particular shape in all of the colour variations or one of each shape in different colours. She now recognises the four different shapes. But you can adapt the game to play in any way which you see fit. Because the game uses pairs of cards it can be played either as memory or snap. I will shortly be publishing a black and white version of this game to support those children who work better using this colour scheme. Keywords: SEN, memory, shapes, colour, game, learning through play, snap, EYFS, Curriculum for Excellence, numeracy,

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. Keywords: science, microscopes, DIY, simple, fun activity, biology, STEM, STEM activity, STEM project, Science Club, STEM club.

Mini Plenary Cards (Grey Backed Cards)

(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 grey backed design. Keywords: formative assessment, mini plenaries, plenary, assessment.
