Chemladdie's Science Resources

Resources that have been written by an experienced science teacher and delivered to real classrooms full of real students. All students are different and all teaching styles are different - what suits you may not suit another so feel free to adapt and change the resources to make them fit your style. I work in a school where money is tight so it is necessary to use a good deal of imagination.

Using a stage micrometer - intro to cell size calcs

(0)
GCSE microscopy Students often find the lessons on combining use of eyepiece graticule and stage micrometer confusing. This lesson allows students to build confidence with the stage micrometer and the idea of measuring sizes of small objects. The lesson starts with a quiz on sizes and measuring prefixes. Use the worksheet as a prelude to a practical activity. End with a written description of how a stage micrometer is used. Follow this lesson with lessons on using an eyepiece graticule and the associated calculations
Alleles, dominant and recessive traits expressed

Alleles, dominant and recessive traits expressed

(0)
This presentation goes with the game sheet doc. I used it to teach some low ability students how dominant and recessive alleles are expressed. It worked really well. Use it as a game for higher level students. Blow it up to A3 size for lower ability 1 - model the alleles of the first child to show students what to do. 2 - Students then get to work on the 2nd and 3rd children’s characteristics 3 - Then they apply their knowledge to the 4th child. Finish off by answering the questions at the end of the presentation. There’s a fun plenary at the end too.
Lesson plan:  Refraction without a practical activity

Lesson plan: Refraction without a practical activity

(0)
This lesson plan allows you to deliver the key points of refraction without your class working on ray boxes, blocks, prisms etc. The lesson plan has some key questions to answer at turning points of the lesson so that you can check understanding. All you have to do is tailor a powerpoint with images readily available from the web. It just depends on what prior knowledge the students have and what type of equipment they may already be familiar with. Intended for students aged 14-16 doing GCSE level learning of properties of light and waves

GCSE transect sampling - ppt includes printable worksheet slide or just do it from projector

This handy ppt allows you to work with data gained from sampling - Once you’ve been outside to show the technique or gathered data that isn’t as good as you wished use this ppt. The ppt has a slide to print off with a sample next to a building - then a table of data to work with; follow this up with some questions. Then round it off with a 6 marker on designing a method for sampling. Plenty to do and lots of scope for learning about data.

Sustainability - roleplay and a lot of fun with serious debate too

(0)
This lesson is great for covering Sustainability in 1 lesson. There is loads of fun and engagement from students as they participate in wasteful lifestyles; then, speculate on how to protect the future generations. Written work included. This will fit any syllabus that requires knowledge of sustainability or impact of humans on the future. The accompanying ppt has the prompts required to get you started on your debate at any level.

Space week - 4 activity packed lesson plans, technician requirements + powerpoints to accompany

(0)
Space, engineering and collaborative working; all delivered in a themed week that has students launching real rockets, finding real debris from space, learning how low energy propulsion can be used with gravity and the engineering skills required to design structures. This set of lessons includes 4 lessons to deliver an engaging Space Week. Included are Powerpoint Presentations, technician requirements, and detailed lesson plans. Oh, and there’s also the real but occasional risk of a rocket exploding on the launch pad. Take pictures, slomo videos and deliver presentations and you’ll have material to review in assemblies or class evaluation days too. All given with an overview which includes a suggested class rotation to get the whole department buzzing about space. 1 - Escape velocity - build and launch a space vehicle 2 - Rocks from space - find meteorites and observe them 3 - Space propulsion systems - How gravity slingshots work and solar sails 4 - Survival on exoplanets -construct a structure with limited payload resources Students can access this content at any level and ability range and still learn a great deal about STEM and space
Plant anatomy - wash off and present a real plant then use sci keywords to describe it

Plant anatomy - wash off and present a real plant then use sci keywords to describe it

(0)
This is a great intro to a plant biology topic. Students learn the parts of the whole plant, prepare a real one for pressing and learn how to use scientific writing to communicate their discoveries. Follow this up with lessons that focus on specialised plant cells. Students take a real plant and wash off the soil then learn about the various organs on the plant. Use for organisational hierarchy too Lesson plan, technician requirements and ppt presentation included in the package
