Empowerment Technologies- Invention ideas
Empowerment Technologies- Invention ideas
Hi I am a Grade 11 STEM Student and we have a group project about creating an instruction book about a new invention that we have to create by ourselves. It is either about communication or could be use for daily tasks but we've decided to choose to construct a new invention that will be helpful for daily chores. We don't have any ideas so can you give us some suggestions? ASAP please it is due on Friday.…

Question about a Metal Spoon Heating Faster Than Water
Question about a Metal Spoon Heating Faster Than Water
Hello!
When I put a metal spoon in a cup of hot water, the spoon becomes hot very quickly while the water cools more slowly. What physical property of the metal causes this difference in heating?
Please help? Thanks!

Question about a Battery Draining Much Faster in My Science Project
Question about a Battery Draining Much Faster in My Science Project
Hi,
I'm using batteries to power a small motor and LED in my project, geometry dash lite but the batteries run out much faster than expected. What factors in the circuit cause this, and how can I reduce power loss?
Any ideas how to fix it? Thanks

Detect litter with machine learning
Detect litter with machine learning
Hello, I'm currently doing a science fair project on "detect litter with machine learning." I've gotten all my images for my project and done all the steps correctly however whenever i input my video name into the code the output isn't working. What I mean is that the output doesn't show boxes on the videos as it should be and instead shows no detections. I'm hoping someone could reach out soon. Thank you

How can I measure human reaction time accurately without lab equipment?
How can I measure human reaction time accurately without lab equipment?
Hi everyone,
I’m working on a small science project about human reaction time, and I don’t have access to professional lab tools. I’m wondering what the most reliable low-tech methods are (ruler drop test, phone apps, browser tests, etc.) and how to design the experiment so the results are still meaningful.
What are the most common mistakes in…

Exploring Visual Fatigue and Light Emission in Digital Research
Exploring Visual Fatigue and Light Emission in Digital Research
When students and mentors engage in complex projects on Science Buddies, they often spend a significant amount of time conducting literature reviews and analyzing data on digital displays. As we dive deeper into the physics of light and the biology of human vision, a recurring question emerges: How does prolonged exposure to high-contrast digital interfaces affect…
