DIY organization Autonomous Space Agency Network just sent a Trump protest 90,000 feet in the air. And it didn’t even cost that much to do it.

hey guys!! it has been a while :’))

however, i have finished my first semester of chemistry (pre-ib) and i felt as if that i did pretty well in this subject even though i had minimal background knowledge on it. i initially struggled with the concepts we did, but after studying hard and trying my best i have gotten used to it and have been improving so here are my tips and tricks for chemistry!

please understand that i have not been through all the topics in chemistry, i have only learnt about atomic structure, periodicity and bonding so my links and tips may only help you for those topics but they should help with the other topics also. (this is most likely a general chemistry masterpost btw)

important study tips:

ask questions in class!!!!!! this is incredibly important, as also for every subject but if you don’t understand the concept you will struggle like how i did in the beginning :( if you are too shy to ask your question in front of the class, go up to the teacher when you have some time or even email them. even just ask your friends or classmates who may have a better understanding of the concept, it definitely helps having different explanations on the same topic, having different perspectives and all

find good resources, go through past tests, past exams and worksheets so that you can have good practice of what may come in your tests and exams. my teacher was very organised and had plenty of resources for me to use to revise and learn in my spare time out of class. it also gave me the experience of the ib tests and exams so i knew what was to come

as said in my maths masterpost, try teaching others when they need help (if you understand the topic and they don’t) because this really seems to help me when studying for tests, i helped my friend with her questions about atomic structure and found myself learning and revising at the same time because of this

repetition!!! you may not get it right the first time, or even the second, but after lots of tries and times you will get there!! trust me :’))

if you don’t have resources, go search for some. there are plenty of studyblrs who do chem as a subject and im sure they are more than happy to help you (me too but i haven’t through many of the topics lol) once you have been through all the past papers you own, go google for some, especially ib kids, theres some out there for you!

have a periodic table with you at all times when studying chem! its a bit obvious but you would most likely need it

apps + websites: 

periodic table apps (there is loads on the app stores but here are some i found)

periodic table [ android | ios ] very indepth and informative (glad i just found this one, im downloading it rn)

periodic table (this one is different) [ android | ios ]

there is plenty, so find the app which suits you and your learning needs

molview (this website allows you to draw molecules!!)

ibchem.com for my fellow ib chem students, this website has notes and other resources to help you with your studies

2016 ib data booklet (there is probably going to be a 2017 one soon but anyways this will be useful

khan academy chemistry (honestly this website is a blessing to all students, so helpful !!!!)

23 science facts we didn't know at the start of 2016

1. Gravitational waves are real. More than 100 years after Einstein first predicted them, researchers finally detected the elusive ripples in space time this year. We’ve now seen three gravitational wave events in total.

2. Sloths almost die every time they poop, and it looks agonising.

3. It’s possible to live for more than a year without a heart in your body.

4. It’s also possible to live a normal life without 90 percent of your brain.

5. There are strange, metallic sounds coming from the Mariana trench, the deepest point on Earth’s surface. Scientists currently think the noise is a new kind of baleen whale call.

6. A revolutionary new type of nuclear fusion machine being trialled in Germany really works, and could be the key to clean, unlimited energy.

7. There’s an Earth-like planet just 4.2 light-years away in the Alpha Centauri star system - and scientists are already planning a mission to visit it.

8. Earth has a second mini-moon orbiting it, known as a ‘quasi-satellite’. It’s called 2016 HO3.

9. There might be a ninth planet in our Solar System (no, Pluto doesn’t count).

10. The first written record demonstrating the laws of friction has been hiding inside Leonardo da Vinci’s “irrelevant scribbles” for the past 500 years.

11. Zika virus can be spread sexually, and it really does cause microcephaly in babies.

12. Crows have big ears, and they’re kinda terrifying.

13. The largest known prime number is 274,207,281– 1, which is a ridiculous 22 million digits in length. It’s 5 million digits longer than the second largest prime.

14. The North Pole is slowly moving towards London, due to the planet’s shifting water content.

15. Earth lost enough sea ice this year to cover the entire land mass of India.

16. Artificial intelligence can beat humans at Go.

17. Tardigrades are so indestructible because they have an in-built toolkit to protect their DNA from damage. These tiny creatures can survive being frozen for decades, can bounce back from total desiccation, and can even handle the harsh radiation of space.

18. There are two liquid states of water.

19. Pear-shaped atomic nuclei exist, and they make time travel seem pretty damn impossible.

20. Dinosaurs had glorious tail feathers, and they were floppy.

21. One third of the planet can no longer see the Milky Way from where they live.

22. There’s a giant, 1.5-billion-cubic-metre (54-billion-cubic-foot) field of precious helium gas in Tanzania.

23. The ‘impossible’ EM Drive is the propulsion system that just won’t quit. NASA says it really does seem to produce thrust - but they still have no idea how. We’ll save that mystery for 2017.
