Rings of Saturn will disappear today.
The ring of Saturn is almost completely water and ice with some dust or chemicals. The ring is 170,000 miles wide. The ring holds 35 trillion-trillion tons of dust rocks and ice. The reason that the ring is visible and shiny is because it reflects the sun, but every 15 years the ring turn reflecting no sun. Saturn’s ring is bit of a mystery because scientists don’t know how it formed. Saturn has an orbit of 29.7 years but we have 365 days. The famous predictor Galileo Galilei was the first man to discover the change of Saturn’s ring in 17th century, through one of his telescopes made by himself. He didn’t know what they were sand he couldn’t see closely enough so he thought that Saturn had two big ears. Then after studying it for 2 years he says it disappear and dint know what to say. There are still some thing for us to still learn about Saturn’s ring.

This lizard runs on water-really!!!
There is one lizard that can run on water. It lives in tropical forests in south and North America. It name is the Jesus Christ lizard. It can weight from 200-600 grams and they grow up to 3 feet. They are able to perform an impossible task running on water, thanks to its large feet and toes which have flaps that allow them to run on water, if they run at a rapid pace. Young lizards can run from 10 to 20 meters before they sink, but adults can only run a few meters. When the lizard sinks if starts to swim at a rapid pace allowing them to get away from the predators, but also trying to not go deep because of the water predator looking for a snack. They are also masters at camouflage and they are omnivore which means that they will almost eat anything.
