WELCOME TO LET’S TECH!!!

Our project CLIL(Content and Language Integrated Learning) in Institut El Morell is called Lets’s Tech!

This year we will start with FOOD PRESERVATION TECHNOLOGY AND FOOD SAFETY.

In this blog you can follow the materials studied in class as well as our daily work and pictures. We hope you enjoy it and we eagerly expect your comments and visits…Let’s tech!!!

CONDITIONS FOR THE GROWTH OF MICROBES – FOOD PRESERVATION

We’ve conducted our first experiment to observe the conditions which favour microbes that spoil our food to grow and thrive.

We used rice for this first experiment and we’ve settled different conditions. In the following pictures you can see how much rice has changed after 1 week and after 2 weeks.

TUBE A: raw (uncooked) rice, room temperature (15-20 degrees), no water.

After 1 week–>TUBE A 1st week      After 2 weeks–>TUBE A 2nd week

TUBE B: Boiled Rice; room temperature (15-20 degrees), water and air presence

After 1 week–>TUBE B 1st week      After 2 weeks–>TUBE B 2nd week

TUBE C: Boiled rice; in the fridge (3-4 degrees), water and air presence

AFter 1 week–>TUBE C 1st Week        After 2 weeks–>TUBE C 2nd week

TUBE D: Boiled rice; room temperature (15-20 degrees), covered in oil, no air presence

After 1 week–>TUBE D 1st week          After 2 weeks–>TUBE D 2nd week

CONCLUSIONS DRAWN BY THE STUDENTS

A) Only rice from tube B got spolied, therefore the conditions we have to avoid are the ones found in tube B.

B)Microbes need water, air, a warm temperature and a time lapse to grow and thrive.

C) The conditions in B have to be avoided when packaging and storing our food.

TOOLS

Last September, our technology room incorporated new tools.

During the first term, we’ve been working on the first information worksheets about these tools which include a picture and some information in English

During this second term we’ve made new tools worksheets: sanding paper, screwdriver, g-clamp and kraftknife!
