Trying to Save Falling Students… Science Fair 2015


The All-Subject Project

As it says above, it was Science Day and everybody participated. I thought “I could use this opportunity for my lazy students not to flunk the subject”


I told almost a month in advance. From 19 scheduled projects… only 5 showed up. I wanted to strangle them like Homer on Bart.



Anyway, I did what I could… and I was kind of glad they weren’t a lot of projects. It was kind of crowded.



The once who enjoyed it was my son who was with me that day.



I loved the smell of this one.



The effect of acid rain on plants.

Heat Detector

For what it seems a very long time ago, I found this Scientific Experiment which I used for my 3rd and 4th grades back in 2011. Results were OK but I took a high risk with little kids.

This November 2012 I retook it for my ever lovely 9th graders (3rd grade of Secundary). Results were better that expected since I was expecting a bonfire. I have some troublemakers.


First we arranged the pieces and wrote the instructions.


Then in teams, I gave them the material and we did. Of course, some wax ended on the floor, some rubber bands snapped, some cardboard arrow were burned around the edges… minor details.


On the sweet side, they love it and I was relief that I didn’t have to use a bucket of water.

Teaching Human Body Systems to first graders

Very awesome!!!

New Teaching Era


When I read I had to teach the HUMAN BODY SYSTEMS, my mind was simply blank! I didn’t know how I was gonna do it without confusing the guys and mainly I needed to figure out a way to have them understanding the functions of every organ the simpliest way possible. So, when I was getting really frustrated it suddenly hit me! 

First of all, my students worked on the basic vocabulary with the help of my students teacher as it was time for her practice period. They were given pictures of the body systems and the basic terminology. They made posters with color big pieces of paper, by teams of course, and they used their dictionaries to find the verbs needed to write about how they work.

After that, I realized they needed more help so I designed the following lesson plan.

1. Split the group in teams…

Science Fair 2012

Super cool idea… Check the Pixel Museum if you have time!

For second unit: the museum exhibition project, I gave my students choices like: animals, dinosaurs, science and insect.

They choose science, so the Science Fair was on.

I surfed a lot searching for easy and less-messy experiments. This is the list of the 19 experiments that I liked the most with instructions and explations.

This presentation is introduce the topic or to get ideas to know what to expect or to review the results of all experiments.

They worked their translation skills and the use of dictionary with the instructions. The good thing that the scientific language has a lot of words with similiar meaning in Spanish.

The result were… more or less. Some teams disppointed me, some surprised me and others did exactly what I was expecting of them.


The welcome sign. I liked it a lot.


This girls really made their effort but the dough got so watery. It didn’t work like it should.


This team got it right in all aspects. It was really good and they had fun.


Also a good example of an easy experiment. One member of the team really gave it all explaining to the younger grades.


This team make the experiment but they forgot the writing showcasing the explanation.


The experiments were presented to younger grades.

Museum exposition

Like as many of us, I had concers with this project for unit 2.

  • What topic?
  • How to make it meaningful and related to English?
  • Where is the best place to get the information?
  • What kind of information for 5th graders who are really deficient in English?

Thankfully I have some decks of flashcards that I bought at Target last summer ($1.00 each). They’re dinosaurs, animals of the world and insects.

Using the flashcards, we worked the vocabulary and classifications. Thankfully, my students found the dinosaurs very hard sooooo we only worked with animals and insects.

The best exhibitions were this.

Experiments for science-related topics, part 3

This experiment is a spin-off of the classic drinking carnation, the one that you see how plants absorb water.

This is the drinking blue carrot expermient.

I like this one because it’s less visible and more interesting… Be concern about the use of knifes but you can ask students to cut it with their hands.


Sadly, it didn’t work like I expected. Probably, the carrots didn’t “drink” like they should because they have been harvested a long time ago, “dead”. I think you need recently harvested (don’t know where to get it).

That’s why you gotta try them first at home, safety first and avoiding nasty surprises (for all experiments)….

Soooo… I’ve got 1/3 of experiment success. No problem! Thomaas Edisson had a lot of unsuccessful experiments before getting right the lightbult.

Experiments for science-related topics, part 2

Another experiment that I used for 3rd grade is Freezing Oil and Water (it’s my only third classroom and with freezer included, thank you Desayunos Escolares)… Regretfully, I didn’t work like it was supposed to. I don’t know where I went wrong.

The idea was to see the frozen density effect. Normally, oil is on top of water. However when they’re frozen, oil should go to the bottom of the glass.

Try it and tell me your results.
