Perch vs Sea Lamprey dissection !!!

  • Compare the perch to the sea lamprey based on your observations My perch was a female and it was very easy when I got it open to see the eggs but on my perch I got a male but on a friends fish, it was harder to see the eggs.
  • Talk about your experience with dissecting… what did you like? What didn’t you like? I liked dissecting the perch because the perch didn’t smell as bad as the lamprey. I didn’t like the sea lamprey because it was gross and it feeds on fish blood.
  • What did you learn about the perch? That the perch had bigger insides than the lamprey.
  • What did you learn about sea lamprey? I learned that the sea lamprey had no heart weird right?
  • What observations did you make? I made an observation about the sea lamprey that the top is a different color than the bottom of the sea lamprey.

Science This Week

 

What is saving Fred you ask? Saving Fred is where you get a gummy worm/ Fred gummy lifesaver cup/ boat

 

What is the objective? The objective was to get Fred in the lifesaver in the boat/ cup and you cant touch Fred with your hands.

 

What are the materials?  gummy worm paper clips and lifesaver and boat

 

 

What challenge excited you the most? Why? The challenge that excited me the most was saving Fred. Because it had enough parts for everyone to have a role. Also, it gave people a chance to share their ideas.

 

What was difficult about the challenges? I think what was difficult is people getting their jobs, the thing is there were enough jobs just my group could choose jobs without fighting. Some of the jobs were the following, Grabbing/ holding Fred, Fliping the cup, grabbing lifesaver.

 

What was comfortable about the challenges? Something comfortable was sharing ideas/combining ideas. My group’s plan was to use one person’s idea for one thing and another for a different thing, this way we all got to share our ideas.

THE GATHERING

Some things to think about:
– What you noticed
– Your thoughts
– Your wonderings
– How you felt being there
– Etc.

 I noticed that some people at the gathering were sad or mad. I also noticed that some people had disabilities or they didn’t want to talk our they couldn’t talk. I wonder if the people there that aren’t eating there are trying to raise people’s spirits? My thoughts are if we could do this more often because I enjoyed talking with some of the people there. It felt good to serve people that don’t have the things you might have.

ORGANIC VS INORGANIC

Throughout our science unit, we have been focusing on an organic and inorganic material. As an experiment, we decided to compare the growth of a bean seed in organic material vs inorganic material. We developed hypotheses and predicted what type of material our bean seeds would grow best in. Over the past three weeks, we have observed our bean seeds once or twice a week to see how they are changing and growing. Below are my observations I noticed today.

Here is a picture of my bean seed growing in inorganic material:

Here is a picture of my bean seed growing in organic material:

My observations about my bean plant that is growing in organic material are……

It grows bigger and faster. it lokes more healthy than the others

My observations about my bean plant that is growing in an inorganic material are….. it doesn’t grow fastest

Conclusion: I think the plants grew better in ______organic soil_________ material because of these reasons: more nutrients then the perlite plant.
