Our Super Science Experiment - Part 1

In Science we have been learning all about mixtures in our Mix It Up! topic.

We did this fun Science experiment to see which substances from a range of 10 different food products found in a kitchen would dissolve in cold water and which ones wouldn't.

We revised some of our scientific language we've been learning about related to mixtures such as soluble, insoluble, dissolvable and non-dissolvable.

We made hypotheses about each of the substances and how we thought they might behave. There were some very interesting predictions and well thought out answers. Well done 2G super scientists!

We tried stirring in artificial sweetener, regular salt, chicken salt (to observe if a different kind of salt would behave differently in mixing), pepper, curry powder, coffee, chocolate powder, ground ginger, ground nutmeg and sesame seeds.

We observed the mixtures during the stirring process and what they did immediately after, as some looked like they had dissolved but then started to settle on the base of the cup. Some of the substances partially dissolved and stayed like that. Others almost dissolved completely! It was very interesting to see the differences and similarities we observed.


Here's some pictures of some of us pouring and stirring, helping each other and watching what happened...
 



















When we were all done with the stirring of the mixtures, we looked at each of them to test out our predictions and discuss the preliminary results...


These pictures show our experiment an hour later, there were some differences in the substances settling.



We left the mixtures overnight to see the results and any changes today. We will be continuing this experiment so stay tuned for part 2!

Keep up the super work 2G Science stars! Well done!
