3. it's what the investigator thinks will be affected during the experiment. a) Control group b) Independent variable c) controlled Variable d) Dependent variable

4. anything that could influence a test, but is controlled (prevented) from doing such. a) Control group b) Independent variable c) controlled factor d) Dependent variable

5. the selected factor that will be used to affect the test. a) Dependent factor b) Independent factor c) Controlled factor d) Experimental group e) Control group

6. it is what the investigator thinks will affect the dependent variable a) Dependent variable; b) Independent variable c) controlled Variable d) Control group

7. A boundary or limit in the test that will not affect the test. a) Experimental group b) Control group c) Dependent parameter d) Independent parameter e) Controlled parameter

8. A limit that is different from other limits, thus having an affect on the test a) Independent parameter b) Control group c) Dependent parameter d) Experimental group e) Controlled parameter

9. A result of having an independent parameter in the test. a) Experimental group b) Control group c) Dependent parameter d) Independent parameter e) Controlled parameter

END OF TEST

Homework Measuring Lab write up due Tuesday. Construct the crystal model due Wednesday.

Today’s Work Construct Crystal Model

Instructions 1. On one facet, put your name, period, date. 2. On a second facet, write the name of the crystal 3. Lightly color all facets of the crystal

3. On a third facet, draw On a third facet, draw 4 rows of 10 columns of molecules, showing how crystals are formed from repeating patterns of molecules.

5. Cut out the model on the SOLID lines. 6. Fold on the dotted lines. Make sure your written material is exterior so it can be seen. 7. Glue or tape tabs making the model self standing. 8. Turn in completed by Wednesday.
