So my nephew always loved science- it was his favorite subject in school. This year (6th grade) he hates it - he is so discouraged and I think it might be an overambitious teacher? This is her first year teaching science after resigning from a different profession. **I get that just because it's her first year doesn't mean she doesn't know what she's doing.** So please I hope nobody takes offense to this BUT I can't help but feel that this class is her "guinea pig". He is in a normal curriculum. Not Advanced. Not Honors. Just plain Science class. My sister looked up the typical curriculum and it's nowhere near what he is coming home with. She googled some of the questions and 10th grade curriculums showed up for most of the questions.

If you have a child in the 6th grade, or teach science in the 6th grade - is this in line with what you see?
I'm going to copy/paste the latest homework.

18. You are now wearing scuba gear and swimming under water at a depth of 66.0 ft. You are breathing air at 3.00 atm and your lung volume is 10.0 L.

Your lungs expand (pressure and volume are inversely proportional). As the pressure decreases, the volume of your lungs increases.
