* Activity 3.1 : Chemistry and physics.
LESSON 3 : CHEMISTRY.
3.1.a What is chemistry and physics in science :
DONT COPY AND PASTE ANYTHING, WRITE THE ANSWERS USING
YOUR OWN WORDS.
a) Both chemistry and physics study matter. What is matter and what
is it characterized for?. Check LINK A and write in a doc file what
matter is and what mass and volumen are too. Paste pics.
b) What is chemistry and what is physics?. Check link A to find out
and write the answer in a doc file.
b) In order to understand Physics and chemistry is important to check
what chemical and physical changes are. Check the LINK B and write
the difference between a chemical and a physical change. Paste a pic
for each sort of change too.
