Atoms, Elements, Compounds and Mixtures Webquest

Write your answers in your science notebook

ATOMS!

1.  Atoms are SMALL!  Visit this site and adjust the slider at the bottom of the image to see the size of a carbon atom.  If you were that small, what would you experience or see?  Write a paragraph describing what it would be like to shrink to the size of an atom!
2.  Visit this site and read about atoms.  Draw a model of an atom.

3.  Elements are pure substances made of ONLY one kind of atom, like gold, iron or carbon.  Elements are all around you!  Visit this site and play the game Avogadro’s Element Hunt to identify elements you may find in your home.
________________________________________________

COMPOUNDS!

4.  Compounds are substances made of two or more elements bonded together in molecules.  Compounds are all around you!   List some substances in your home that are made of more than one kind of element. (H2O, Salt…think of some more!)

MIXTURES

5.  Mixtures are different that compounds.  A mixture has two or more elements or compounds in it, but they are not bonded together and can be separated.  An example is salt water…the salt can be separated from the water by dissolving the water, leaving the salt behind! Visit this site to read about mixtures.  Draw a picture showing the difference between a mixture and a compound.

COMPARE and CONTRAST

6.  Visit this site to compare elements, compounds and mixtures.  Copy and fill in the table below in your notebook.
How do elements, compounds and mixtures look different?
(Hint: Look at the ‘Notes’ setion under the pictures)
