Study Tips, Help with H.W., Managing Anxiety

Class, I'm uploading a few files that I believe can help you with writing, reading, speaking, and presenting throughout the year. It could even help you when you have to present for the Science Fair. Take a look at them by clicking on the links below. Also, there are some Study Skills tips below too, and a number to call for free help with homework. Check it out:

Managing Back-to-School Anxiety

*When studying for Science Tests/Quizzes, it's always good to use a combination of these resources:
- Read and study all your class notes
- Study worksheets given (highlight them too)
- Look at Videos/links on my blog (YouTube helps too)
- Look at the different websites on the Websites and Resources for Science folder on my blog, including Ducksters.com (for Fact information)
- Make Flashcards of important Vocabulary terms
- Practice on Quizlet website (Flash cards, Match games)
- Take practice Quizzes (on my blog, under Quizzes folder)
- BrainPop videos + Review Quizzes (and take notes on the videos)
- Read Summary Notes (if given) or Study Guides, including the      Study packet that covers all 3 years of Science
- Practice past 8th Grade Science State Exams (link on my blog)
- Practice on IXL + Khan Academy

- Study Textbook (look at Chapter Tests, Vocabulary words)
- Make a study group with friends (you can test each other on different topics)


Here's a quick video on BrainPop with tips on how to study and prepare for a test --> BrainPop- Test Preparation

Topics for the Scientific Method Test

Topics on the Scientific Method Test:

-Observations

-Inferences

-Predictions

-Data

-Independent, Dependent Variables

-Constants (controlled variables)

-Control group, Experimental group

-Steps of the Scientific Method, including Conclusion

*If you would like to review the Vocabulary for the test, check out this site, it has important Vocabulary--> Reviewing Variables

Independent & Dependent Variables

*This is an excellent video that goes over Independent and Dependent Variables, and it explains why we need to only change 1 variable at a time.

Here's another great video showing the differences between independent and dependent variables:

1) The 1 thing we test, change, or is different between groups in an experiment is the independent variable (we control it!)

2) What we measure or observe at the end is the dependent variable. It's the data we collect.

3) Constants (controlled variables)- Variables that are kept the same, do not change.

TIPS:

Independent variable- "I" change it.

Dependent variable- depends on the independent variable.

Think of Cause (IV) and Effect (DV). The IV comes first (the cause) and the DV comes after (the effect).

So when writing a Hypothesis, the format should be: If the (independent variable) changes, then the (dependent variable) will change because...

Remember, the ONLY variable we change in an experiment is the independent variable. Scientists control all other variables so they can be sure that the results are caused by the independent variable only! This is called a controlled experiment. And it allows the experiment to be fair.

Also, you need to repeat an experiment several times to make sure your results are reliable or valid (accurate).These are called trials. If you do an experiment just 1 time, you might make a mistake or get a strange result.

More Vocabulary:

1) Experimental group- the group that is tested or receives the change.

2) Control group- the group that is not really being tested (gets no special treatment). It's the standard, used for comparison only.

3) Sample size- the total number of people/animals/plants being studied in an experiment. 

4) Placebo- a fake pill that contains no active ingredients but is used as a control in testing how well another, real pill works.

5) Trials- the number of times you do a test in an experiment. The more trials you do, the more reliable the experiment is.

*A control group is used to see if the change actually works (compared versus the experimental group).

*A large sample size is better for an experiment because your results will be more reliable or accurate since you have more data to count on.

Class, this is a video on LAB Safety discussing the top 10 rules to follow in LAB.

This is another short cartoon video on LAB Safety.

This is a rap video on LAB Safety.

And finally this video is from Amoeba Sisters, also showing important guidelines to follow in LAB.


***You will be tested on these videos, including the safety rules learned in each one and during class.

SUMMARY OF IMPORTANT LAB PROCEDURES:

•Notify the teacher of any emergencies.

•Do NOT touch anything unless told to first.

•Do NOT fool around in the LAB.

•Read all LAB procedures first before doing anything.

•Keep aisles clear.

•No food, gum, or drinks allowed.

•Always wash your hands and clean up after yourself.

Forms of Energy

All energy comes from either the main 2 forms, Kinetic or Potential energy. So the forms of energy shown below can either be classified as kinetic or potential energy. Copy down everything you see here, and draw a picture or example of each one, showing that type of energy:

1) Nuclear/Atomic Energy is stored in the nucleus of an atom and released when you split atoms.

2) Chemical energy is a form of potential energy that is stored in organisms, food, gasoline, or chemical bonds of molecules.

3) Electrical energy is produced by electrons moving through a wire; it's a natural and man-made energy form.

4) Mechanical energy is the energy in the motion of objects. All moving objects have mechanical energy.

5) Sound energy is produced when a solid, liquid, or gas vibrates. Sound energy travels out as waves in all directions.

6) Thermal energy is the energy of molecular movement. The faster the molecules move, the more thermal energy is present. Heat is the transfer of thermal energy. So when thermal energy moves from object to object, we feel it as heat.

7) Light (radiant) energy is a form of energy produced by the sun and lamps; it's visible to the human eye

Plate Tectonics REVIEW

Class, here is a copy of the chart that shows the 3 types of Plate boundaries and their effects. You can click on it to see it bigger. This will be on the test. Study it! The topics for the test are shown below the picture:

This is a link to the video I showed you in class that showed all the animations of the different types of boundaries. Just click on it and look at all the videos on the left-- The Geological Society- Animation Videos on Boundaries
Here's another link that shows you some animations of boundaries-- Exploring Earth- Visualization


These are some notes from class on the 3 boundaries:

- Convergent boundaries: 
a) When an ocean plate converges with a continental plate, the denser ocean plate slides under the continental plate = Volcanoes or Trench (SUBDUCTION ZONE)
b) When two ocean plates collide, the denser ocean plate slides under the other ocean plate = Volcanic islands or Trench                
(SUBDUCTION ZONE)
c) When two continental plates collide, they crumble up = Mountains

- Divergent boundaries: 
a) When two ocean plates move apart, this causes seafloor spreading = Mid-ocean ridges OR Ocean basins
b) When two continental plates move apart = Rift valleys (a low point)

- Transform boundaries: 
When two plates slide past each other = Earthquakes

This is more information on the sub-types of Convergent boundaries only. Click on the picture to see it bigger:

Pictures of Boundaries:

These are the topics on the Plate Tectonics test:
- Pangea
- Evidence supporting the theory of Pangea
- Continental drift
- Seafloor spreading
- The names of scientists who developed these theories
- 3 types of boundaries and their effects
- Convection currents (due to density differences)
- VOCABULARY: Lithosphere, Asthenosphere, Mid-ocean ridge, subduction zone, etc.

*You should also know this: Differences in density cause the hot, plastic-like rock to be forced up toward the surface, causing the plates to move.
