  2. Lab Safety 1. Explain the importance of lab safety when conducting experiments in the class room. 2. List at the minimum 3 types of lab safety equipment and describe their function.

  3. Scientific Process 3. The scientific process is a series of steps designed to aid a scientist through the experimentation process. Choose the answer with the correct order. • Formulate a conclusion, research the problem test the hypothesis • Design the experiment, identify the problem, analyze the results • Develop a hypothesis research the problem, formulate conclusions • Identify a problem, test the hypothesis, formulate conclusions

  4. Scientific Process 4.This variable depends upon what is done to it by the independent variable.
