00:00Science Heroes, Episode 2, The River That Cried for Help.
00:04Asterisk Liam, the inventor, loves building gadgets.
00:08Asterisk Sophia, the environmentalist, deeply cares for nature.
00:12Asterisk Jaden, the science whiz, always experimenting.
00:16Asterisk Ava, the peacemaker and communicator.
00:20Asterisk Maya, the brave one, never afraid to act.
00:24It was a sunny Saturday in Redwood Town.
00:26The science heroes were enjoying lemonade at their clubhouse when Sophia received a message on her eco-watch.
00:33Alert! River contamination levels rising in Westbrook River.
00:37Aquatic life in danger. Urgent response needed.
00:40Sophia gasped. That's our town's river. It's where the ducks swim and kids play.
00:46The team rushed to their bikes and rode straight to Westbrook River.
00:49When they arrived, the usually clear river was cloudy and smelled strange.
00:54Dead fish floated near the banks.
00:56Jaden scanned the water with his aquascope, a device he made using a microscope and a phone camera.
01:02Jaden Asterisk, the water has too much nitrate.
01:05This is fertilizer runoff.
01:07Liam Asterisk, someone nearby must be overusing farm chemicals.
01:12They traced the stream to a large farm just a few miles upstream.
01:16On the farm, they met Mr. Thomas, a kind but old-fashioned farmer.
01:20Maya Asterisk, sir, your fertilizer is leaking into the river.
01:25Mr. Thomas Asterisk, I didn't know. I just want my crops to grow faster.
01:29Sophia pulled out her tablet and showed a simple animation.
01:33Too much chemical fertilizer equals water pollution equals dead fish equals unsafe drinking water.
01:39Liam suggested a solution.
01:41Let's build a natural filter barrier using gravel, sand, and plants to clean runoff before it reaches the river.
01:48The team worked with Mr. Thomas to create a biofilter near the edge of the field.
01:53They planted water-purifying plants like cattails and lilies.
01:57Liam used recycled pipes to slow and direct runoff into the filter area.
02:02They tested the runoff after passing through the filter.
02:05The nitrates had dropped by 80%.
02:07Mr. Thomas smiled.
02:09Now I can grow crops and protect the river.
02:12A week later, the team returned to Westbrook River.
02:14The water was clear, birds were chirping, and fish were swimming again.
02:19Sophia, smiling, we didn't just save the river.
02:23We taught a community, Jaden.
02:25And we proved science can solve real problems.
02:28The science heroes raised their hands in the air.
02:31Altogether science.
02:32Action.
02:33Kindness.
