Whale Observation

On our whale observation the class went looking for whales at the point. So we can watch there movments now and then when we go on the whale watch later in the season we can look and there movments. We also look at there behaviors also to see what the whales are doing.

Question:
Will we see more whales jump early in the season than later in the season?

Hypothesis:

I hypothesis that there will be more breaches early in the season because the whale will be more active during this part of the season.

It was ok for me because I have done this lab before last year. But this time when we went to the look out it was a little different for me because I have never used a climonter before so it was something new for me. My faviort part was that was the first time of the season that I got to see a whale this season. There was one challenge that I had was that are weight fell off more than once. I saw one whale that was just showing its back.

Clinometer Blog

1. Spot a whale
2. Hold your clinometer to your eye looking through your eye peice.
3. Have your partner take the reading on the protracter on the outside line.
4. Then you convert it in to feet using the floumal of (ft*dgr*tan=?)

•The graph you created for your data analysis section of your lab write up.

The graph that you see is the number of different breach from the two different observations that the science class did one in March and the other in Januaray.

Conclusion

Will we see more whales jump early in the season than later in the season? I hypothesis that there will be more breaches early in the season, because the whale will be more active during this part of the season. There for my hypotheses was sported because I saw more whales breaching early in the season then later in the season.


Some sources of error where the position of the boat, miscounting the whales, difference in the data collection on land vs. off land. Another reason is that the class went observing at different times so the whales where less active.

My experience on the whale watch boat was good because I knew the captian of the boat. I love going on whale watches because you only get to see them for a few months out of the year.
