Lab Blast – Science Investigation Game (Ages 8+)
The school’s science fair has finally arrived, and excitement fills the lab. Students proudly present their experiments—colorful mixtures, bubbling flasks, and carefully prepared projects.
But during the very first demonstration, something unexpected happens: a sudden mini-explosion rocks the room. Luckily, no one is hurt, but the equipment is damaged and the fair is temporarily halted.
The project had been tested before without any problem, so this strange incident raises questions. Was it really an accident… or something more suspicious? Kids step into the role of investigators, follow the evidence, and solve the mystery behind the lab explosion.

I used this mystery game with my second grade class at the start of the school year. I split the class into small teams, and each group worked at their table to solve the clues. When they thought they had the right answer, they called me over to check, and I pointed them to the next one to find. They searched for the clue, then came back to their table to work it out. The whole thing ran beautifully — simple, fun, and a great way to build classroom connection right from the start.
