TEXPO 2024 now open for entries

CSES Schools' TEXPO: Fri 21 June 2024, ARU Chelmsford (9am for 10am start, latest 3pm finish)

For Y5-13 | Show your project to scientists and engineers | Cash prizes | Free lunch!

Are you in a STEM club at primary or secondary school? Have you made or investigated something fantastic in technology or science lessons? Have you been doing interesting technical projects at home?

Are you a teacher who'd like to showcase your pupils' / students' work? Or are you a parent, guardian or tutor whose child has been working on an exciting project?

If your answer to any of these questions is YES, then exhibit at the annual CSES TEXPO. There is prize money to be won and we even provide lunch!

We welcome projects from all areas of science and technology. This could be something you've made, software, experiments, reports, posters, videos etc. Entrants to the competition are encouraged to submit projects that they have been working on already in class or at home, including those for coursework, meaning that no extra work is necessary. There is no need to have a 'finished product', and your project can be originally from another competition or scheme.

Show your work to our judges, who include professional scientists and engineers, and you'll be in with a chance of winning a prize!

CSES continues to support schools with technology and engineering

CSES bursary kits granted to Chelmsford County High School for Girls

As part of the ongoing commitment to education, support and inspiration Chelmsford Science and Engineering Society (CSES) has been working with Chelmsford County High School (CCHS) for girls.

CSES member Ed Bye has been working with a group of sixteen keen and enthusiastic year 10 (14/15 years of age) students at Chelmsford County High School.

One lunchtime a week during the autumn term, the students have been exploring control electronic engineering and stored program systems based on the Micro:bit microcontroller.

In the world, there are by far many more devices (microcontrollers) than computers. With increasing electronics finding its way into all sorts of items, this number will grow. As an example, a typical budget low-end car has about 25 microcontrollers, a high-end luxury car can have over 50 microcontrollers.

The current generation of students will be using microcontrollers, developing their own equipment and projects to solve engineering problems. Thus, giving young students some insight and experience with microcontrollers puts them at an advantage and an early start.

To enable some understanding and to provide some practice with this technology, Ed designed a kit of parts to work specifically with the Micro:bit. There is a variety of about 25 sensors and actuators, shown below. These could be used in numerous projects in conjunction with a Micro:bit.

Centenary Photographic Competition 2024 Poster

Centenary Photographic Competition 2024: Time

For Primary and Secondary Students

Taking a camera or your phone and shooting a picture is an easy. But how about, when composing your image, you think about how your picture might be used to discover some aspect of science and engineering?

STEAM: Science, Technology, Engineering, Arts, MathematicsFrom your camera or mobile phone to a flower or a rainbow, from a bubble to radio mast, from smoke to light, from microscopy to astronomy, everywhere in our modern world we are facing science and engineering wonders that make our lives easier and more fun. This is the fifth year of our competition and we have had some outstanding winners.

Science meets Art – Our annual photographic competition aims at creating an opportunity for you to creatively express what you observe within science, in pictures, and we hope that this will get you to explore the visual aspects of STEAM through the art and science of photography and capture images that demonstrate and communicate STEAM concepts and phenomena.

This year 2024,

the focus of the competition is on:


(Including everything from clocks, hourglasses, sundials to biological clocks, sunsets, stars, ancient monuments and more!)

We want you to take photographs (up to 3 entries per person) that express what Time means to you or how it impacts health or our environment, including the negative or positive roles of technology. Each photograph must be accompanied with a short plain language explanation (not more than 50 words) of the thoughts behind your photograph.
