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.
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!)
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.
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)
7. Visit this site to play a game sorting elements, compounds and mixtures.
8. QUIZ: Visit this site to quiz yourself!
Draw the table below in your notebook…take the quiz and record your answers.
9. Visit this site about SOLUTIONS AND MIXTURES. Answer the questions below in your notebook:
Is a heterogeneous mixture a solution? How do you know?
What are the steps to making a solution?
Can anything change solution? Be specific!
What is solubility?
