A worksheet aimed at either 14-16 or 16+ students that are studying the nature of radioactive decay. The worksheet involves learning about the process of radioactive decay by starting with a highly unstable radioactive element and then working through the products of each subsequent decay. Starting with uranium 238, students fill in 14 separate decay stages (showing mass number, atomic number and name of new element formed) until the stable isotope of lead 206 is formed. The activity provides an excellent way of practising and reinforcing ideas on alpha and beta decay. A full answer key is included

This activity provides a way in which students can see the three dimensional structure of protein for themselves - once the activity is completed, the teacher can then display ribbon diagrams of proteins (e.g. enzymes, haemoglobin, etc) so that students can see the connection between textbook diagrams and images and their model.

A resource aimed at BTEC Level 3 Applied Science students, this worksheet provides a series of research prompts for students to explore the nature of a scientific theory. The context of the theory of evolution is used in this task, with students being required to research the evidence for this theory and some of the competing and discredited ideas that were believed (and still are by some individuals) until the evidence for evolution by natural selection became overwhelming.

A resource aimed at either GCSE or BTEC Applied Science Level 2 or 3 students, this starter activity provides a recap of the meaning of atomic number and mass number with reference to the periodic table of the elements.

A resource aimed at GCSE (14-16) biology students, this activity requires students to construct a model of cells at different stages of division in order to learn how chromosomes behave during mitosis. The worksheet includes images of cells at different stages of division to assist students and also some questions that should be completed at each stage of the process.

A resource aimed at either GCSE (14-16 year olds) or Advanced (16 -19 year olds) biology students, this worksheet provides a diagram of a typical prokaryotic (bacterial) cell. The task involves labelling the diagram to identify each organelle, followed by a mix and match task to describe the function of each organelle. This resource is ideal for use as either a starter activity to recap previous learning or as a plenary exercise following a lesson on this topic. Key words: prokaryotic, cell, organelle, capsule, membrane, cytoplasm, ribosomes, nucleoid, chromosome

This resource is aimed at GCSE (14-16 year old) biology students and consists of two worksheets. The first worksheet is an introduction to the concept of cells, tissues, organs and organ systems and involves a mix and match task to sort key definitions. The worksheet also has a table to fill in with specific examples of cells, tissues, organs and organ systems. The second worksheet consists of eleven questions that are related to an online video that neatly (in the space of 3-4 minutes) introduces the topic of the digestive system. Students watch the video (link to the video is provided on the worksheet) and answer the questions as they go. This is ideal to use as a starter task for a lesson on the digestive system.

This resource consists of two 'active video' worksheets linked to online Youtube videos (links provided on the worksheet). Each video consists of a three to four minute video clip showing some engaging applications of diffusion. The first video clip shows a team of scientists testing shark repellent under water and the second shows a skunk spraying musk as a defense mechanism. Each worksheet provides simple questions that students answer while watching the video - providing the opportunity to then commence a full lesson on the topic of diffusion.

A worksheet aimed at GCSE (14-16 year old) students, this resource is ideal as a starter activity following a lesson on the principles of osmosis. The worksheet includes several questions that probe understanding of what osmosis is, how we can use knowledge of osmosis to predict water movement into and out of cells and finally a challenge question on how salt can be used to kill slugs by dessicating them. Keywords: osmosis, water, hypertonic, hypotonic, isotonic, concentration, turgid, flaccid, plasmolysed, slug, salt

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

Science students often struggle to understand the concept of a control investigation, something which is regularly examined by most exam board specifications. This worksheet explains clearly what a control investigation is and then provides several practice investigations which require students to describe a suitable control. Finally, the worksheet provides an extra 'challenge' question for more able students to describe how control experiments were important in establishing the germ theory of disease and debunking the myth of spontaneous generation.

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

A worksheet aimed at advanced level biology students, this resource has a series of questions that require students to calculate water potential values in order to predict the direction of water movement between different cells. The worksheet also has diagrams of both animal cells and plant cells showing water movement in, out and no net movement - students are required to match each diagram to the circumstance that would cause each effect. A useful worksheet to review understanding of the key ideas involved with osmosis
