Fourth-graders have ingenious solutions to the world's biggest problems
This is The Medical Bot. This group of students invented a robot to help people who can't get to a hospital quickly. The robot is able to scan your body to tell what is wrong and then can perform anything from putting on a Band-Aid to giving you stitches.
Another idea for better health was Vita-Ice, ice-cubes made from powder that has vitamins in it. The kids didn't like how their vitamins tasted, so this was their flavorful solution.
This group recognized that kids are eating too much sugar, causing diabetes and cavities. They invented the Fruity Candy vending machine that dispenses fruits and vegetables disguised as candy. Their prototype even had a refrigeration system to keep the food fresh.
Some students wanted to solve problems specifically for kids. This app called Kid's Work allows teachers to communicate with parents what their homework assignments are. The students discussed how their classmates often lie about doing their work, so this app would motivate them with weekly prizes.
Another problem for the students is heavy backpacks. This high-tech bag called The Massagenator has a built-in massage system to make sure your muscles don't get sore while carrying a lot of books.
A lot of the students were concerned about pollution, especially growing up in a big city. This air-conditioner system plugs into your window and converts polluted air to clean air.
These fake flowers also clean polluted air, specifically from factories.
Some students even thought about water pollution and created an underwater machine that picks up littered trash with robot arms.
Another recycling robot works on land to turn trash from the streets into fun toys.
This Transformer acts as a money donation station for people (and apparently YouTubers) to give back to others in need.
This shelter helps homeless people who lost their houses in natural disasters. The houses will be built to withstand hurricanes and tornadoes.
Another home improvement idea was a security system that has automatic bars come down on the windows and doors if there is a break-in and can be controlled from your smartphone.
Of course the kids didn't forget about their pets. The Nugget Catcher is a bracelet attached to a claw machine that will clean up after your dog, proving that no problem is too small when you're in the fourth grade.
