Prokaryotic and Eukaryotic cells
The Cell *suitable for home teaching*
This is an extensive resource package, which includes the Wellcome Trust Big Picture magazine. In addition to the magazine there are several presentations which include some great images that will help students to develop their using of the cell as a 3D structure.
These images would work well as class presentations; one of the presentations is an activity where students have to identify the presented images (answers are provided). There is also a useful video on working with cells.
What's in a Cell? *suitable for home teaching*
This is an article from the Catalyst magazine. The article includes detailed electron micrographs of two Acinar cells from a pancreas, which would work well on a white board or on hand held devices.
Students could be asked to identify as many organelles as possible (with a description of their function) and then compare this with the detailed key provided on the final page of the article.
There are many ways to make effective use of Catalyst articles, a booklet has been produced which provides ideas on how Catalyst articles can be used with students and includes six exemplar activities. This booklet can be accessed at: https://www.stem.org.uk/elibrary/resource/27308
Seeing Inside Cells *suitable for home teaching*
This Catalyst article shows how various types of microscope allow scientists to see what is going on inside living plant cells. Students could be given this article as pre-reading for a lesson, they could be asked to make use of the web link in the article to view images from a range of different microscopes.
ABPI interactive website
This is one page from an extensive set of interactive resources developed by ABPI. On this page students consider how cells are grouped to form tissues and organ systems. There is also an animation on sub-cellular structures of a Eukaryotic cell and a 4 question quiz on organelle function, this could be used for independent study.
Video for teachers on aseptic technique
This is a good video for teachers and technicians who are not confident in the aseptic technique required to manipulate cultures without introducing contamination. The video shows a range of operations that could typically be employed in a school laboratory or preparation room. The correct procedures can then be demonstrated to students.
Nuffield microbiology practical guide
This is the Nuffield Foundation standard technique for culturing organisms using aseptic technique. It is a useful protocol to use as it is straightforward and concise.
Basic Practical Microbiology: a Manual
This manual from the Society of General Microbiology provides a basic introduction to microbiology, aseptic technique and safety. It is a useful guide for teachers and many of the photographs within the booklet could be used to demonstrate to students the techniques in culturing microorganisms
Microscopes for schools
Although originally a MRC project for primary schools, there is a lot of useful information and guidance on this website for GCSE Biology students. The page on how to use a microscope is a useful reminder for Key stage 4 students before they use a microscope to look at plant and animal cells.
Students could be asked to prepare their own "how to use microscope guide" and then compare it with this one.
The experiments page provides straightforward protocols for the observation of a range of organisms
There is also a page of useful images and videos that teachers could use to introduce this topic, as well as a list of further websites which could be used as possible websites for students to investigate as a homework activity
Model Cells
In this short video, wallpaper paste in a plastic bag is used to model a bacterial cell. This video could be watched as a class activity with students asked how effective a model is this, what's good/not so good about it? Students could then work in teams, tasked with producing a better model of a cell. The results could then be "judged".
There are numerous examples of models on Youtube, students could view this before starting their project. For example: https://www.youtube.com/watch?v=5b5ziuSBUiw
