Sens-ational Science Club...Online

I'm so glad you are here! The content below is designed as a once-a-week club, but feel free to work through it at whatever pace suits you. 

Before you begin...

This content is all free to access, but if you are able to, please consider contributing to help me keep making content like this in the future.


Welcome to the Sens-ational Science Club! I hope you enjoy it. We are starting out with an overview of your amazing brain and senses- just hit play below to start discovering why you can't always trust your senses...

Week 1: Vision

This week we are looking at probably the most important sense for humans- vision. First up, here is a video introduction to this sense, and some of the tricks we can play on it.


Next, it's time for some try-it-at home fun. This week, you will be making your own illusions which you can try out on friends and family. Just download the instructions here:

This weeks activities

involve cutting, so make

sure you ask an adult if you

need help. They will also need

to help you to poke a hole in a piece of card with a pin. There is glue involved, so be warned, things might get a little messy! 

Watch out!

In case you want to try it for yourself, here is a copy of the checkerboard illusion from the video for you to print out & play with. 

If you have any questions about this week's club, or just want to tell me how you got on, you can email me:


I'd love to know what colours you and your family saw on the Benham's top!

Week 2: Hearing

This week it's the turn of our sense of hearing. While our hearing isn't as good as many animals, we can still use it to understand speech, enjoy music and work out where scary noises are coming from- this week you will discover more about how we do these things.

For this week's at-home activity you'll find out about localising sounds- finding out where they are coming from. You can download the instructions here: 

This one needs two people,

and a bit of space. Why not

try it in the garden if the

weather allows? Try to make

sure the 'sound seeker' stays still while they are blindfolded- we don't    want them bumping into anything

       or falling over!

Watch out!

I love hearing from you, so please do send me an email to or message me on social media if you have any questions or comments. 

Week 3: Smell, Taste & Temperature

This week we will be looking at three senses- smell, taste and temperature. While they are all important individually, these senses often work together, and in the introduction video we will be doing some experiments to show how this happens. To join in, you'll need something fruity to eat (a sweet, a piece of fresh, tinned or dried fruit, juice or squash or even some jam) and something minty (a sweet or some mint tea, for example). If you don't have a minty sweet, you can use some toothpaste, but make sure you do it in the bathroom so you can spit it out!

This week, there are two hands-on activities to try. The first is a trick you can play on your sense of temperature, and the second  is an exploration of taste and temperature. You can do it using any food you have in the house. You can download the instructions here: 

These activities involve hot water, and heating up foods, so please ask an adult for help 

Watch out!

Don't forget you can send in any questions to or message me on social media. I love a challenge- so no question is too big or too small! 

Week 4: Touch & Proprioception 

Your senses of touch and proprioception allow you to find out about the world around you, but also to have knowledge of your own body. This week, you will be finding out more about these two vital senses. There are a couple of demos in this week's video that need a second person, so grab a helper before you hit play!

The activity sheet for this session looks in more detail about how your sense of touch varies in different areas of your body. This is a two person activity, so grab a helper and download the worksheet using the button below:

Toothpicks can 

be sharp, so make  sure your don't put them anywhere near  your eyes, or your       helper's.

Watch out!

Were you surprised about how much better some areas of your skin were at detecting touch? Let me know by emailing or messaging me on social media. And as always, if you have any questions about your body senses, or your brain in general, please do send them in too. 

These two senses aren't ones we normally think about, but they are really important. Balance is vital for every movement we make- we all know how hard it is to walk straight after you've been spinning around! And our sense of weight allows us to judge how to pick up an object, without dropping it, or crushing it.


For one of the experiments in this week's videos, you will need two identical coins. Give them a quick wash with some soap, then pop one in the fridge to chill. Keep the other one with you- either put it in your pocket or hold it in your hand until it is roughly the same temperature as your skin. Leave them there until you get to the right point in the video to join in with the experiment. Then hit play below!

Week 5: Balance & Weight

For today's activity, you will be making a weight illusion for yourselves. 

This is a project that involves cutting & sticking, so supervision with the         scissors is                        recommended. 

Watch out!

If you don't have a printer, you can draw your own nets for the cubes- this video shows you a few different ways you can do this.

Don't forget, if you have any questions, you can email me: or find me on Twitter @GinnyFBSmith. I always love hearing from you, so do let me know how you got on with the illusions. See you next time for the final week of the Sens-ational Science Club!

Week 6: Multisensory

In this final week of the club, we are looking at how our senses work together.

One of our brain's most important roles is to combine the information from all of our senses, and to make sense of it. One illusion that gives a great example of how this happens is the McGurk Effect, which you can see in this video. Do you hear something different for each set of syllables? What happens if you close your eyes?

To find out what's going on, and how some people's senses get mixed up in unusual ways, hit play on the video below:

Now it's time for you to become a real scientist, and devise your own experiment. This week's worksheet will help you come up with a hypothesis, for how two senses work together, and carry out an experiment to test it. I have given you a few examples, so if you are struggling to come up with your own, you can always use one of those. But I'm sure you can come up with better ideas yourself- let your imagniation run wild!

As part of the experiment, you need

to think about how to keep yourself safe-             make sure an adult            helps with that part!

Watch out!

I really hope you have enjoyed the last 6 weeks. If you have, please share the link below with any friends or family you think would enjoy it too:

Don't forget, if you have any questions, you can email me: or message me on social media. I would love to know what hypotheses you came up with, and whether your experiments supported them!
