Biology lab safety rules

In the last biology class we went to the lab. There we saw the safety rules and we discussed some of them. Here are the rules we put so we can work with safety.

Lab Safety Rules

  • Don’t run inside.
  • Be tidy and avoid rubbish.
  • Avoid long sleeves.
  • Hair must be tied up.
  • Never drink or eat inside.
  • Let teachers know when materials get broken.
  • Wear goggles in the correct way.
  • Never smell subst. directly when heating subst. or liquids.
  • Keep test tubes with their opening away from heat.
  • Never refill the original container with the substance, just discard it.

Biology Activity

Our Biology teacher assigned us to make an activity that explained the menstrual cycle with our Base Groups. We could chose between a song, a rap or a mind map. At first we doubted between a rap or a song, but we chose the song. Also, when we made the rap we realized that it didn’t explain the menstrual cycle very well, so we made it a again. I was absent many classes, so I couldn’t work very much on this activity. Here is the rap:

Inside the ovary, a follicle with an egg is developed, uterus lining repairs like it doesnt care.

 

Follicle bursts, egg released, fertilisation can occur like a formation.

Uterus lining thickens, ready for embryo if the egg is fertilised, very organized.

 

Egg not fertilised? Thickness not needed. It breaks down, and it is lost through the vagina.

Biology Project Self Evaluation

The biology teacher asked, after the presentation of the project, to post a self evaluation of our work on it.

I was the first one who got the potato, I didn’t like at all at first, but then I got used to it. I took three photos of it and posted them on my blog. After that, I gave the potato to Matias Campion who also took photos of it. We began to have trouble because we were confused when to post the photo of the potato. Matías Campion gave the potato to Matias Hartmann and he posted some photos too. As I said before we didn’t know exactly when to post the photo of it because we lost the count of the days. The potato grew a lot since it was given out to us. The roots are a lot larger and the kind of plant it had is larger to. All of us left the potato on a plastic bowl with water. The first days and the last ones didn’t grew very much, it grew the most when Mati Campion had it. It was an interesting project and it was interesting seeing the potato growing just by putting water in it. At first I didn’t like the potato at all, but at the end I liked the project very much. I think we did a good work, but we failed a little bit on posting the photos, we could have posted more photos and measure the potato to see how it grew in a better way.

Biology Potato Project Last Day

This is the last day of the Biology Potato Project. We took the last photo of it. It grew a lot since the first day, specially the roots are larger. In this photo the roots seem shorter because of the lack of water, but in another photos you could see how they grew. Also, you can see how the plant it had also grew a lot. We did a chart in google documents to show the growing of it in a more organized way. Here is the photo of it:

Biology Project Day 1

In the last biology class the teacher gave us to choose between a potato or an onion to take to our homes a see how they grew. The work is in groups of three, I am with Mati Hartmann and Mati Campion. Mati Hartmann is the facilitator, Mati Campion the secretary and I am the presentator. Today is the first day, every two days we have to give the potato to another group member and take a photo of it and post it in our blogs. This is the photo of it.
