Mr. Carter, the reporter of the week, shared some fascinating facts about African Bullfrogs. African Bullfrogs are found in Africa. The tadpoles hatch after only two days in the eggs. Did you know that males can grow to be the size of a cantaloupe? Females get to be about half the size. The males fight each other over mating rights and they're fights get pretty intense. We're glad we don't have to fight over friends. Thanks Carter!
Our scientist of the week, Mr. Silas, shared a science experiment that tied in perfectly with what we learned from Mr. G yesterday. He asked us whether an egg would float better in plain water or salt water. We had some good reasoning and 12 of us thought salt water while 5 of us thought plain water. Turns out salt water is more dense than plain water. The egg floats in salt water because it is less dense and the egg sinks in the plain water because it is more dense. Water that is more dense pushes the egg up just like high air pressure pushes on marshmallows and makes them shrink. Silas shared that the Dead Sea is really salty and really dense. Now we all want to take a little trip across the pond! Thank you Silas!
