Biology Assessment

For the last Biology class we had to make a project choosing one of the teacher’s projects that she left on her Blog. The day of the presentation we had to assess the groups that presented based on a rubric that the teacher left on her blog. I worked with Manu Carrizo and Lucas Vorbeck. Manu was the one who bought the cake and we made it at his home. We took the information from photos from the internet and the biology book  we use in class. The only problem we had was deciding the size of the cake, but we think it was good at the end.

Here is the assessment that I made:

Group 1:  23/28

Group 2:  23/28

Group 3:  21/28

Group 5:  24/28

Group 6:  22/28

Group 7:  22/28

Group 8:  26/28

Biology – Animal Cell information

In the last Biology classes we were learning more about the cells. We were divided into groups and each group had to choose between doing an activity with animal cells or plants cells. I worked with Manu Carrizo and Lucas Vorbeck. We had to choose between the activities Ceci, our teacher, left on her Blog.  Before doing the activities we had to post information about animal cells or plant cells.  We had to show what they have and how they work.

Here is a drawing I made of an Animal Cell.

The Animal Cells are multicellular and Heterotrophs. They do not have cell walls or chloroplasts. They also do not have chlorophyl. They have a cell membrane, a nucleus, mitochondria and cytoplasm. Sugar is produced in the mitochondria. Also, the nucleus contains chromosomes. The nucleus contains the DNA of the living organism too. That is the basic information about the Animal cell.

Comparison Chart of Monocots And Dicots

Today on our Biology class we saw the differences between Monocots and Dicots, then we made a chart showing the differences using the information on our books and a presentation showed in class. Down here is the chart we made.

Characteristics of Kingdom Animals (Phylum Invertebrates – Group Arthropods)

Today in our Biology class we followed the instructions of our teacher and we complete the table below with the information of our books from pages 11 and 12. Down here is the link to the chart we made.

Characteristics of Kingdom Animals (Phyllum Vertebrates)

Today on the Biology class our teacher, Cecilia Adem, asked us to follow her instructions on the whiteboard and post the information on our Blogs. We used the information of pages 9 and 10 from our Biology books. Down here is the chart we made in class by the information of the books.

Biology Chart

Class Skin Gills or Lungs Limbs Eggs Ears
Fish

(Cold blooded)

Scaly Skin Have Gills Have Fins Eggs laid in water Absent but lateral line senses vibration
Amphibia

(Cold blooded)

Scale-Less Skin The larva has gills, the adult has lungs Have legs Eggs laid in water, larva lives in water Visible Ear, present inside the head
Reptiles

(Cold blooded)

Scaly Skin Have Lungs Most reptiles have limbs, others don’t Lay eggs on land with rubbery shells, then they get harder, waterproof Don’t have very visible ears, very small
Birds

(Warm blooded)

Body covered with feathers Have Lungs Wings (forelimbs), 1 pair of legs Lay eggs with hard shells Have eardrums
Mammals

(Warm blooded)

Body has hair Lungs 2 pairs No eggs Present, Ear pinnae present

 

Characteristics of living organisms

Today the Biology teacher, Cecilia Adem, gave us some exercises to learn and practice about the living organisms. you can see the exercises she gave us clicking here. She also asked us to work in pairs, I worked with Lucas Vorbeck.

Activity 1

  1. The living things can make their own food, eat, move and most important they can grow. Humans, animals and plants can die, while not living things cant. The living things can also breath and reproduce.

2. We can see two humans, two dogs and a tree.

3. The clothes, a house, a stick the dog is holding, the kettle and the glass a man is holding.

Activity 2

  1. The car needs oil to be used, if not it cannot produce energy to move. We need food to get energy and move. The car can move, humans, animals and plants can move too.

2. Because the car cannot grow, the car needs to be moved it cannot be moved by itself, the car cannot reproduce or breath.

Activity 3

a. Growth

b. All animals and plants

c.  Photosynthesis

d.  Irritability and Movement

2. Organism, Respiration, Movement, Nutrition, Growth, Reproduction, Excretion, Irritability.

Activity 5

  1. Duck, house-fly, bat, eagle, owl and mosquito.
  2. Bat and owl.
  3. Fish, whale, seal and duck.
  4. Those organisms that have feathers: Duck, eagle and owl.
