Tests for cations and anions

I recently created a set of matching cards for a student who was struggling with answering exam questions on tests for anions and cations (click here to download). I´m also going to use them during revision lessons with GCSE students.

I wish you great lessons!

Water density

A few years ago I came across an article in the Catalyst magazine called "Water in the oceans". Apart from discussing whether or not salty water in the oceans would mix, it had a simple experiment which explored water density.

Start with two cups of water. In one, make a saturated solution salt solution and add food colouring of your choice. To the second cup of water just add different food colouring. Once done, try mixing the two together and you will get two distinctive layers.

This is a great experiment to use in a lesson on density. Super easy and cheap to prepare.

I wish you great lessons!

What can you teach with this seemingly useless equipment?

Surface tension of water is one of the options. How? Have a look at the video:

This easy to prep experiment is great to merge fun and learning. Click here to read more about the science behind this activity.

Chemical magic

If you need to run an open evening and showcase your department it´s good to have a selection of experiments and demos that will leave the audience speechless. I have already discussed the classic ammonium dichromate volcano (click here) and today I would like to share some chemical magic. This simple to set up experiment when paired up with a bit of acting can easily surprise your audience as you turn water into wine:

Then wine into water:

and lastly water into milk:

I tested it in beakers but for your "official" demo I suggest following the instructions and use wine glasses and a glass milk bottle.

If not used as a demo, you could use it in your lessons to discuss phenolphthalein as a narrow range indicator. Furthermore, it could be used in precipitation reactions lesson.

I wish you great lessons!

Edexcel 6 marker chemistry questions

For some students 6 marker questions are a real nightmare and they tend to ignore them during exams. With a bit of regular practice it is easy to develop skills which will allow the pupils to tackle those questions. I went through 3 years of Edexcel Chemistry GCSE papers and put together a document with all the 6 marker questions. I referenced each paper so you can easily find the right mark scheme. These questions can be used as homework tasks, extension tasks and with the mark scheme for peer assessment. The document consists both foundation and higher questions.

Book of Achievements for KS3 Science Club

Science Club is for me a place where the students have an opportunity to conduct experiments they wouldn´t normally have a chance to do. It´s an opportunity to further deepen their curiosity and develop lab skills. I created the Book of Achievements to teach my students organisational skills and show them how much they can do. The list of "achievements" to complete is a great starting point to create independent learners who know how to plan.

The reward system is flexible and can easily reflect whatever your school is doing - merits, stickers, postcards home etc.

I wish you great lessons!

KS3 Science Club - Scheme of Work

I have been running after school clubs since I started working as a teacher. I really enjoy the freedom a science club can give you to try experiments that you wouldn't normally have time to do in a lesson. One of the restrains that I had to face, however, was the issue of money to buy the resources I needed. This I managed to overcome by applying for grants and getting free resources (I mentioned some of the places here). After testing a wide range of experiments and getting feedback from my students, I put together this KS3 Science Club Scheme of Work, which I hope is going to be useful for your students too.

I wish you great lessons!

Let YouTube help you teach Science #5

Today I would like to share a fantastic demo which you can use in your classroom or as a part of an open evening.

The rainbow flame demonstration is easy to set up and gives you an opportunity to have a great show stopper.

Which topic/s could you use this demo with?
- alternative to the flame test
- transition metals

Key words:
- emission spectrum, metal ions, safety, transition metals

What is Kahoot!?

Kahoot! gives you an option to engage your students in highly addictive quizzes and learn at the same time. Students absolutely love the competitive aspect of those quizzes. As a teacher, I really like the fact that I can either create my own quiz or browse through the database of thousands of quizzes created by others. Another interesting feature is the option of creating a report which shows you in detail how well your students performed and what are the areas that still need work.

Mystery Boxes

I recently came across an interesting hands-on activity which will help the students learn how scientists work and how they come up with different theories.

As you can see from the video it's very easy to set up and extremely engaging. I can't wait to try it soon.

I wish you great lessons!
