Berkshire 7th Grade/9th Grade Science

At a hot air balloon festival, hot air balloons slowly fill and then magically float within our atmosphere.  How do these hot air balloons fly?  Use Boyle's Law and Charles' Law and explain your answer.  I'm looking for an extended response to receive the full extra credit. Use the internet to help with your answer.    

Blogs should be thought-out, well written and quality 9th grade work. Due by Thursday, 3/10 at midnight. For safety purposes, please don't include your last name or email. If your post is not accepted by me, it means it did not meet the criteria above and wasn't eligible for extra credit.

The government estimates that over 206 million gallons of oil spilled into the Gulf of Mexico from the Deepwater Horizon oil rig.  Oil is extremely toxic to all wild life, and the toxic effects hit the marine life from the minute the oil hit the water. Using your knowledge of biomes and how human actions can effect an ecosystem, describe at least three marine animals that were effected by this tragedy and explain how those animals can effect the rest of a marine food web.   

Blogs should be thought-out, well written and quality 7th grade work. This means doing your research (don't just guess) and writing a response with at least 50 words or more.  Due date is by Sunday, October 24, 2010 at midnight. 

If your post is not accepted by me, it means it did not meet the criteria above and wasn't eligible for extra credit. For safety purposes, include your first name and class period.  Do NOT include last names in your post.   

Design a Severe Weather Action Plan for your home in the case of an emergency. Include areas in your home you would avoid, places you would go (i.e. basement), what you would cover yourself with, how you would notify authorities for help and who you would call.  Keep in mind the location you live. For instance, if you live in a house without a basement, what is your alternative?  Remember to include all members of your family and who is responsible for making sure your brothers and sisters are safe.  What if your mom or dad is still at work?  What if your little brother is still at school? 

Your action plan should be well-written and include detailed steps of action.  Blogs that are under 50 words will not be eligible for extra credit.  Use your knowledge of weather (and various internet sights) to help you design an action plan for your family.  Blog are due by Sunday, May 30th at midnight to be eligible for extra credit.

NOTE: do NOT include your last name in your posts.  First name and period number is acceptable.
