Quarter One Quarterly Study Guide

1. How are branches of science Similar: All Scientists follow the Scientific Method and or inquiry process. They make observations followed by research, hypothesis, and experimentation, analyze and conclude their results, and communicate their findings. Each discipline may use different tools to study, however they follow similar experimentation steps.

2. What is the difference between replication and repetition?Scientists also have to “check their work.” The results of an investigation are not likely to be well accepted unless it is repeated many times. Each time the results must be the same. This process is called repetition. If research results can be repeated by the researcher, it means they are more likely to be correct. If, in the repeated trials the answers do not agree, they are likely to be incorrect.Scientists repeat their trials many times before they submit their findings to their peers. It is the scientist’s peers who will conduct even more trials. While the original researcher repeats his trials many times, that’s not enough for an idea to be accepted. It is the job of other scientists to replicate the original findings.

3. What are the variables, controls and constants in an experiment?Control: What is used to COMPARE the results to? It is the variable in which no independent variable has been applied.

Variable: Anything that changes in an experiment. There are 2 types: Independent: What you change on purpose (cause) Dependent: What you observe changing, or What you measure/observe (effect)

Constant:Anything that stays the same in an experiment to make sure that only the Independent Variable is being changed.

4. Where can I find the independent and dependent variable on a graph?

5. What is a scientific law and theory?

6. What are the properties of a solid, liquid, and gas

7. What type of change is the water cycle?

8. What causes sinkholes in Florida? Rainfall percolating, or seeping, through the soil absorbs carbon dioxide and reacts with decaying vegetation, creating a slightly acidic water. That water moves through spaces and cracks underground, slowly dissolving limestone and creating a network of cavities and voids. As the limestone dissolves, pores and cracks are enlarged and carry even more acidic water. Sinkholes are formed when the land surface above collapses or sinks into the cavities or when surface material is carried downward into the voids. A Chemical change!

9 What is temperature and how can it be increased?Temperature if the average kinetic energy of an object and can be increased by adding thermal energy (heat).

9. What is the difference between mass and weight?

10. How do I calculate density, mass, and volume?

11. What are the SI Units?

12. What determines if an object floats of sinks?If an object is less dense than the object it’s submerged in than it will float. If the object is more dense than the object it’s submerged in than it will sink.

13. What are physical and chemical properties?

14. What are intrinsic properties?

15. What is evidence that a chemical change occurred?

16. What are physical changes?
