States of Matter Graphing and Particle Diagrams (KS3, middle school)

(0)
When I teach States of Matter one thing I always struggle to get across is the relationship between energy, temperature and change of state. I’ve designed this resource to try and help with that! It can be used in conjunction with any other teaching methods you use in the classroom and asks students to push themselves a little bit in their conceptual understanding! This download contains 4 documents which you can mix and match as it makes sense for your class. A quick summary of each is below (and there is also a preview): Resource 1 outlines an experiment for boiling water, questions about the procedure and space for drawing particle models. Resource 2 includes a results table and instructions on how to plot the graph (a heating curve of water) Resource 3 is a blank graph for plotting (you can also use graph paper- totally up to you) Resource 4 is further questioning to understand the graph/ heating curve. Resources 1, 3 and 4 all have suggested answers, resource 2 doesn’t have any questions so there is no answer sheet for this one. The folder has the worksheets as pdf individually and combined. This activity is based on one I’ve done with students that actually works really well in the classroom or at home as a practical. However, this resource contains a condensed version of the method so I wouldn’t personally use just this if I was to do the experiment with students. Instead, I use this resource to check for application and understanding. It works well as classwork or homework. I’ve used this with Grade 6 as supported group work but also with higher grades as completely independent work, you know your classes best!

Evidence of chemical reactions (KS3, middle school)

Evidence of chemical reactions (KS3, middle school)

(0)
This is the perfect activity for any unit where you are teaching chemical reactions. E.g. KS3 in the UK curriculum or at any middle school level. In the worksheet students are given three chemical reactions to read about: Zinc and hydrochloric acid/ hydrogen chloride Combustion of iron wool Lead nitrate and Potassium Iodide (a very cool precipitation reaction) They need to work through different activities including: Matching reaction descriptions to “before” diagrams Drawing the “after” diagram for each reaction Filling in a results table (scaffolded) Matching the reaction to the chemical equation Explaining each reaction (scaffolded) See the preview image if you want to make sure it’s right for you. If you need a resource to help your student really get to grips with signs of chemical reactions this is it. I’ve also included a teacher guide which has links to my favourite YouTube video of each reaction and a method to do them as a class experiment (for zinc and hydrochloric acid) or as a demo (for the combustion and precipitation reaction). There is a separate document of suggested answers, too, because no one has time to make that on the fly! If you download and like this resource, I would love any feedback, I want to strive to keep making my resources as user-friendly as possible.
Conservation of Mass Worksheet (KS3, Middle school)

Conservation of Mass Worksheet (KS3, Middle school)

(0)
This is a great worksheet to reinforce the principle of conservation of mass. It works well in KS3/ middle school when teaching the concept for the first time or as a great reminder in high school/GCSEs as revision. It can easily be used after a lab or demo to show the principle in action. The activity follows the precipitation reaction between copper (II) sulfate and sodium hydroxide and is split into 2 parts: Part 1: This looks at the experimental method used, asking questions about how the experiment shows conservation of mass. Part 2: This is more about the chemical equation, using a particle diagram and a table to help students understand the reaction more at a chemical level. I’ve tried to upload a preview image which helps you understand the worksheet a bit better and check if its suitable for your students. In the downloadable folder, there is an answer sheet for all 10 questions and the table as well.
Endothermic and Exothermic reactions (lab based worksheet, KS3)

Endothermic and Exothermic reactions (lab based worksheet, KS3)

(0)
This is a great activity if you want to check understanding and application of key ideas as part of any chemical reactions unit! It’s especially good if you are limited with time or resources for labs in your school. The worksheet outlines 6 different reactions. In Page 1 students must first class each reaction as endothermic and exothermic as well as answer a couple of questions about the experimental method. Page 2 is all about equipment and asks students to decide which equipment would be most effective for measuring a change in temperature. Check the preview to check if it’s right for you! An answer sheet is included in the downloadable folder with some suggested answers. If you want to do any of the reactions I used the following websites (sorry, I can’t share URLs but this should come up with a search result quickly): RSC website- exothermic-or-endothermic-classifying-reactions Middle school chemistry .com chapter 6, lesson 11 If you use this worksheet I would love some feedback! Its great to find out if my resources work for other classes and students as well :)
Ionic formula + word game w/answers (polyatomic ions)

Ionic formula + word game w/answers (polyatomic ions)

(0)
This worksheet contains 22 questions in a table arrangement of either: working out the chemical formula from the compound name (i.e. formula for potassium hydroxide) naming the compound based on its formula (i.e. name KOH) All of the examples in worksheet are compounds of polyatomic ions (carbonate, nitrate, hydroxide, sulphate and phosphate) On the second half of the worksheet is a word game to make words using the letters from two compounds (just for fun/ for the fast workers!) Answers are included, including some suggested answers to the word game.

This worksheet contains 22 questions in a table arrangement of either: working out the chemical formula from the compound name (i.e. formula for potassium iodide) naming the compound based on its formula (i.e. name KI) All of the examples in worksheet are simple ionic compounds, there are no polyatomic ions. On the second half of the worksheet is a word search to find some of the names of the compounds (just for fun/ for the fast workers!) Answers are included, including the word search.

This is a poster that visually looks at several methods of thinking about formula for ionic compounds. It outlines: Crossover/ swap and drop method Balancing charges Hand holding/ branches Lego A easy to use table so that students get to grips with valency
Diffusion investigation template/ lab guide/ differentiated resource

Diffusion investigation template/ lab guide/ differentiated resource

(0)
This is another clean and easy to use template for a differentiated lesson/ block of lessons investigating diffusion using simple equipment. Its a classic experiment that can be done to build lab skills or teach diffusion. This folder includes: A teacher guide with tips on running the lesson 3 different differentiated templates for students using the same format (blank, guided and fill the gaps/ cloze exercise). Each template has a list of words that can be used to help guide the students A suggested set of answers to help students see the level of detail and scientific (but approachable!) answers they could give This could be: A longer lesson including the lab for students familiar with investigation A week long introduction to investigations for less experienced students A series of lessons to explore diffusion as a topic A reminder of investigations at the beginning of the year A group based lab with a shared template and multiple levels of help A break from a series of dry science lessons with something using more independence. This lesson was planned as a classroom activity and to be printed but can easily be adjusted as a home-based learning project that uses simple equipment swaps.
