Adaptations = Living things have structural features and adaptations that help them survive in their environment.
I learnt that animals have many adaptations in different environments. Salt water crocodiles are cold blooded. They stay still in one spot to keep heat. They also stay still to camouflage. Salt water crocodiles can go without food for more then 12 months.
In adaptations I would like to learn more about what makes the animals adapt to the area. Is it the evolution over time? Is it how they were born from the start? How long does it take for them to adapt to different climates?

this video was about how space x was planning to colonize mars. Elon Musk told the world his plan for colonizing mars in mexico. people stampeded their way into the room he was lecturing in.
he told us the first step was to build a rocket ship. first the rocket will be launched into earths orbit because of a big rocket booster. when completed this rocket would be stronger than NASA’s strongest and heaviest rocket SATURN V. the rocket would be powered by 42 raptor engines which is the new better engine that space x has been working on. this rocket runs on methane but you will only find out why later.
so the rocket is launched into the earths orbit with the booster and then the booster with separate from the rocket and come back down to earth. when the booster comes down to earth and quickly gets ready to launch a propellant tank. that tank then docks with the space ship filling it with the gas it needs to mars. musk said it might take 3-5 propellant tank to fully fill the space ships trip.
then the rocket is off t mars. the rocket lands by using its engines to lure itself to the ground. its a technique called supersonic retro propulsion. after letting out the passengers the space ship eventually lift off and come back to earth. where will it get the fuel for that? you might wonder. well hey get it o mars space x is using methane because it can be made from the planets atmosphere.
now my only question is that how will they survive. because mars is even worse than Antarctica. you don’t have food or water in both places but at least in Antarctica you can actually breath. and in which habitats will we live in. also when you go to the moon you get muscle loss. imagine in mars.
i understand that there is not enough room n earth and that people will in the future have to start moving to different planets a the moon.
these are my goals for science
Solids, liquids and gases have different observable properties and behave in different ways
Science involves testing predictions by gathering data and using evidence to develop explanations of events and phenomena.
With guidance, pose questions to clarify practical problems or inform scientific investigation, and predict what the findings of an investigation might be.
Suggest improvements to the methods used to investigate a question or solve a problem.
Compare data with predictions and use as evidence in developing explanations.
Use strategies to help me read and understand scientific texts that use tier 3 scientific language.
thanks for reading my science goals
