Review Time Take 2

REVIEW TIME TAKE 2!!!

We are almost to our long weekend! YIPPEE! Since it getting close to the Science STAAR,  we will be reviewing different sections that we have previously learned.  This is your time to show what you know!  This week will look just like last week.  You will respond under your class homeroom  because each class will have a different topic. Don't just add to the bottom but instead click reply so your answers line up under your homeroom.  You did great last week so do it exactly like that!

NEW TOPICS
Charles: Energy (include types and how they transfer) Think of all the types: thermal, light, solar, electrical, sound
Demeris: Classifying matter:  What are the properties we use and how can we tell if a particular matter has those properties (Look in your science journal)
Juan: Weathering, Erosion, and Deposition: What is it and give examples of each.  Try to find different examples than someone who commented before you.
Coolidge: Weather and reading the fronts. Give examples of weather that occurs as the fronts pass an area.  Try to find real life examples. (not just severe weather)
White: Resources: renewable and non renewable, fossil fuels, Include alternative energy sources as well.  (Geothermal, wind, water, etc) Why should the world move toward renewable energy sources?

Review Time

REVIEW TIME!!!

I hope everyone had a restful spring break! I traveled to Hong Kong and had a great time, although I am a little tired!  We are getting close to the Science STAAR so we will be reviewing different sections that we have previously learned.  This is your time to put what you know!  This week will look a little differently. You will respond under your class homeroom by because each class will have a different topic. Don't just add to the bottom but instead click

Charles: Matter: Solid, Liquid, Gas and physical change or chemical change. 
Demeris: Electricity
Juan: Light
Coolidge: Force and motion
White: Solar System

Lunar Eclipse

People have been fascinated by lunar (Moon) eclipses for ages.  For a time during an eclipse, the full Moon seems to disappear as it changes color, darkens, and then reappears.  Through time, people have had different ideas about what causes a lunar eclipse.  Here are some ideas:

A: A near by planet passes between the Earth and the Moon
B: The sun passes between the Earth and the Moon
C: The Moon passes between the Sun and the Earth
D: The Earth passes between the Sun and the Moon
E:  The clouds block out the Moon
F:  A nearby planet's shadow falls on the Moon
G: The Moon's shadow falls on the Earth
H:  The Moon turns to the dark side and then back to the light side. 

Thinking about lunar eclipse only, not phases of the moon.  Which answer do you agree with most?  I am looking for the best explanations to get a prize this week.  Look for evidence online and list your sites.  Try to find sites that haven't been used before.  ASK.COM or ANSWERS.COM are not valid sites!  If you use these sites you will not be able to get into the prize box this week.  Do not "copy and paste" into the comment section try to put the information into your own words.  Disagreeing respectfully is always acceptable.

NEW and IMPROVED!!! Stemscopes!

We are so lucky to have access to a great science resource.  You will be able to review topics we have already gone over and get vital extra practice on test questions similar to the STAAR. 

The website is hereStemscopes

If that link does not work then the URL is https://springbranchisd.stemscopes.com/

Once you are at the log on screen you can log on exactly as you do when you log on at school.

Short log on and then the password is your lunch number.

This week's homework is to log on and complete at least 20 minutes of practice.  There are games and practice quizzes.  These would be VERY helpful when benchmark time comes around.  This first set will be due Friday November 30.

Hot and Cold Balloons

Mrs. Charles filled a balloon with air.  She tightly tied the balloon so no air could get in or out of the balloon.  She kept the balloon in a warm room.  An hour later she put the balloon in a cold freezer.  When she took the balloon out 30 minutes later, it was still tied tightly shut.  No air escaped form the balloon; however the balloon had shrunk.  Mrs. Charles wondered if the mass of the balloon (including the air inside it) had also changed. 

What do you think?  Is the mass the same or less than?  Give examples, try it out, research on line.  Remember Wikianswers is not a valid scientific website!

Anyone with the right answer and a GOOD explanation will get a pink free sit pass!

Rube Goldberg's awesome systems

We know a system is a group of objects working together to make something happen. Check out these! Can you find all of the energy transfer? http://www.rubegoldberg.com/ 

Also this video is really great example of energy transfer and systems!

OR this old honda comercial is fun too! 

Enjoy!

What's in the Bubbles?

Mrs. Charles is boiling water in a glass tea kettle.  she notices bubbles forming on the bottoms of the kettle that rise to the top and wonders what is in the bubbles.  She asks her friends what they think, and this is what they say:

Dr. Coolidge: "They are bubbles of heat."
Mrs. White: "The bubbles are filled with air"
Mrs. Demeris: " The bubbles are an invisible form of water"
Mrs. Juan:  "The bubbles are empty-there is nothing inside them."
Mrs. Harn:  "The bubbles contain oxygen and hydrogen that separated from the water."

Which person do you most agree with and why?  Look for evidence online or  by doing some investigating at home.  You will get a trip to the prize box for right answers by Friday.  Answers must be complete and have some evidence in order to receive a prize! Have fun!
