Science Filmmaking Behind the Scenes: Measuring Sunlight, UV, and the Power of Hats

If you’ve watched one of our science lessons on YouTube or TikTok, you’ll know that it looks effortless — neat experiments, clear results, and tidy explanations. But behind the scenes? It’s often a balancing act between bright sunlight, sensitive sensors, and cameras that refuse to play nicely.

Recently, we filmed a lesson on how much sunlight and UV different hats can block. A simple idea: put on a hat, place a sensor underneath, and measure how much light (and UV) makes it through. But of course, science filmmaking never goes quite that smoothly.

The Science Setup

• Kit list: A PASCO wireless light sensor, a laptop to log the data, and a selection of hats — straw, cotton, wide-brimmed synthetic, and even a parasol or two.

• Method: Find a sunny day (easier said than done in the UK), set up on the pavement in full sun, and record baseline readings before testing each hat.

The science worked beautifully — the straw hat let through much more light than expected, the wide-brimmed synthetic hat was the clear winner, and the silver-lined parasol was almost unbeatable.

The Filmmaking Challenge

Bright sunlight might be perfect for UV measurements, but it’s a nightmare for cameras. The laptop screen — showing our lovely live data — was so washed out that the camera couldn’t capture it clearly.

Solution? Record the screen separately and combine the two in post-production. That way, the viewer sees both the real-world setup and the crisp digital readout of the experiment. It’s a little extra work, but it turns a fiddly outdoor shoot into a professional-looking lesson.

Why We Do It

The goal isn’t just to tell students about UV and sunlight — it’s to show them. When you can see the numbers shift as the hat goes on or the parasol swings overhead, the science becomes real. That’s the power of mixing hands-on experiments with thoughtful filmmaking.

So next time you see one of our short clips on TikTok or a full lesson on YouTube, remember: behind every simple science demo is a jumble of cameras, sensors, laptops, and a lot of editing magic. And, occasionally, a very bemused passer-by wondering why we’re sitting on the pavement with a pile of hats.
