Christmas Science Experiment - Diffusion
cmrcarrcmrcarr

Christmas Science Experiment - Diffusion

(0)
An activity aimed at either 7-10 year olds (simply do the activity described on the first two pages and ask students to describe their observations) or 11-14 year old students(ask students to complete the worksheet of questions on diffusion), this resource provides a really engaging way of of showing students the phenomenon of diffusion in a quick, simple, creative and edible way! Students are tasked with creating a simple picture or image on a plate using vegetable oil and a drinking straw. Skittle sweets/candy are then added to each area of the image and water is added. The colours from the skittle sweets/candy will start to diffuse and spread across the plate, colouring the image in. The colours are prevented from running into each other by the lines of oil. The activity provides a great way of discussing key questions such as why the colours are spreading, why are some colours spreading faster than others, what effect different temperature water has on the rate of spread of the colour and why oil stops the colours from spreading any further. Most importantly though, the investigation is a FUN science activity tailored to Christmas! The resource includes: Instruction sheet with diagrams, question worksheet for 11-14 year olds and various templates designs for Christmas pictures Key words: diffusion, colour, art, christmas, santa, holly, reindeer, fun, skittles, spread, investigation

A resource aimed at advanced level biology students, this worksheet leads students through an area that often causes difficulty - interpreting evidence for the Calvin Cycle. The worksheet looks at the classic experiment performed by Melvin Calvin that provided evidence for the sequence of events that occurs in cyclic photophosphorlyation or the light-independent reactions of photosynthesis. The worksheet introduces the idea of radioactive tracers and asks students to predict the effect of switching lights off or reducing carbon dioxide levels. Graphs are shown recording the levels of RuBP and GP in response to these changes.

Surface area:Volume - the basic principles and applying knowledge
cmrcarrcmrcarr

Surface area:Volume - the basic principles and applying knowledge

(0)
A resource aimed at biology students studying surface area: volume ratio. This worksheet discusses the nature of surface area:volume ratio and why it is important in terms of gas and heat exchange in living organisms. The first worksheet covers basic principles of calculating surface area and volume of cubes of varying sizes, followed by calculation of surface area:volume ratio. Unlike many textbook resources, this worksheet emphasises the fact that surface area is linked to the ABILITY to exchange whereas volume is linked to the NEED to exchange. The second worksheet considers how this principle is applied to adaptations for heat exchange in different species of fox and finally how metabolic rate is influenced by the size of an organism and its ability to exchange heat with the surroundings. Key words: Surface area, volume, ratio, exchange, cube, heat, gas, metabolism, fox, ears

cmrcarrcmrcarr

Control of the cardiac cycle - electrical activity in the heart

(0)
A resource aimed at Advanced Biology students, this worksheet provides a diagram and questions on how the cardiac cycle is under myogenic control. The worksheet begins with a labelling activity, requiring students to recall key vocabulary such as sino-atrial node, atrioventricular node, Bundle of His and Purkinje fibres. The next task requires sequencing of the appropriate events that occur as electrical impulses are generated within heart muscle. Finally, the worksheet provides some questions requiring more detailed understanding as to why these events happen in the order that they do. An ideal resource to use as either a plenary or lesson starter to recap and consolidate knowledge. Key words: sino-atrial node, atrioventricular node, Bundle of His, Purkinje fibres, systole, diastole, atria, ventricles

cmrcarrcmrcarr

Lung disorders and disease - Fick's Law

(1)
This resource is aimed at A-Level Biology students and lists the mechanisms behind each of four different lung diseases and disorders: asthma, tuberculosis, pulmonary fibrosis and emphysema. As well as being a useful collection of revision notes in itself, the task here is for students to explain how each of these diseases causes a reduced tolerance to exercise - this is often asked in exam questions and requires students to apply their knowledge of Fick's Law. Each disease will impact on surface area, concentration gradient and/or thickness of exchange surface thereby reducing the rate of diffusion; the challenge is for students to explain this
