The Strange Case of Alfred, the Gummy Bear who Drowned in Distilled Water

A certain Gummy Bear called Alfred was found dead, floating in distilled water... To be able to solve this case, we will have to discover certain rules about transport of substances.

Let's talk a bit about your  practical work assignment

For next Thursday October 17th each group from Thursdays  will have to come to the Biology lab  with the following materials:

* 3 small Tupperware cases

* Masking tape

* permanent marker

* spoon

* a bag of Gummy Bears (different colours) (it can be a bag of YUMMY)

* a packet of Halls candies (= pastillas Halls)

* Distilled water (= Agua Desmineralizada). I bought it in the car section at Coto. We'll be ok with one bottle per class.  If you can't find this, I'll bring mine

*salt

*centimeter ruler

You must form 2 groups of 5 members and 2 groups of  6 each

And this is a file for you to print for Thursday and complete on the results for the following week Thursday October 24TH The practical work is in groups
