Pray was really interesting we made rubber balls called gak. I discovered in this prac to make an example of a chemical reaction making gak with mixing pva glue with food die and hot water

# data[].attributes.body
Conclusion for GAK experiment: In this experiment two solutions where mixed two make a chemical reaction. The colour was kept the same with a light blue colour as it had not faded away when mixed. The liquid and solid created a solid that was squishy, blue and movable.

In the prac that we did we observed how and if there was a chemical reaction the to substances that's we used in this prac were PVA glue and borax it was a successful experiment to actually see how the chemical reaction works

The conclusion on the GAK experiment: the two solutions where mixed to make

In conclusion this experiment showed us how to observe substances and how to tell when a chemical reaction occurs

When PVA glue is mixed with borax and water solution, it forms a gel substance called GAK. The reaction occurs when the water and borax mixes with the PVA glue. The end product is GAK, a slimy and stretchy substance that slowly looses its shape after a short period of time. The GAK is somewhere between a solid and a liquid, which we call a gel.

The experiment 'Making GAK' explored how the mixing of certain reactants will cause a chemical relation to occur, and a product will be made. The properties of the GAK changed, therefore a chemical reaction occurring.  For the change to occur, borax and PVA glue were mixed together to create a solid.

In this practical, the class investigated the reaction between borax and glue. The investigation started with us mixing together borax and PVA glue, this created a chemical reaction causing the glue quite quickly evolve more or less to a solid. Concluding the investigation we had a solid ball made of PVA glue and a hint of borax solution. Making the end product GAK

During the investigation making gak a chemical reaction occurred between the pva glue and the borax solution the properties of the solution changed to a gel, the liquid was added to a power which created gak.

The experiment shows that by mixing two reactants it can create a chemical reaction and a new product is made. It is shown that when pva glue and borax solution is mixed it makes a viscous, stretchy material called GAK.

# data[].attributes.body
The gak was made when the borax solution was mixed with the pva glue. This made a squishy gel. This occurred because of a chemical reaction. A chemical reaction can happen when two different liquids or solids mix together.

# data[].attributes.body
As a result of this experiment, being able to tell when a reaction has occured is much easier, for this prac, both the state, the colour and the properties changed, therefore, it was a chemical reaction

# data[].attributes.body
it was learnt that by adding borax solution to PVA glue it went from a liquid to a solid. It formed into a ball like object. It was found that it was not a solid it was a super slow moving liquid.

The experiment 'Making GAK' saw students mixing PVA glue and a Borax solution made of borax and water. The reactants formed a stretchy and bouncy product that was a slow moving liquid. When a reaction occurs the appearance and properties of the product change.

# data[].attributes.body
In this prac when borax solution is poured and stirred with PVA glue a chemical reaction occurred. This reaction made a gel like substances called gak.

# data[].attributes.body
In our experiment we mixed a borax solution with some pva glue which cause a chemical reaction and turned the pva glue thick into "GAK". We explored

# data[].attributes.body
In the investigation "making gak" it was shown that mixing PVA glue and the borax solution would make a stretchy and Gelatinous blob of gak. If you have ever seen or used  play doh that is what it is.  Gak is a viscous and a liquid.

This prac demonstrated an example of a chemical reaction using GAK. By mixing pva glue and borax solution, the chemical reaction made a slimy, stretchy, blue and watery substance known as GAK. The GAK was very different from the borax solution and the glue and was an interesting example of how chemical reactions work

# data[].attributes.body
Conclusion on making GAK: What we discovered is how to tell when a reaction has happened by observing the substance, and seeing if it has changed in certain ways like heat, colour, texture,etc.

# data[].attributes.body
The gak was made out of pva glue and food colouring. The gak was strechy and it was a gel. This means it wasn't a solid or a liquid but somemthing in the middle. This gel was a chemical reaction of the pva glue, the food colouring and the borax soloition

# data[].attributes.body
The GAK was made when the borax solution mixed with the PVA glue. This made a clumpy squishable gel. A chemical reaction occurred when the two properties were mixed with each other.

# data[].attributes.body
It was found that when you mix borax with PVA glue, it creates a reaction that forms 'GAK'. GAK is viscous, stretchy and Gelatinous. It was also found by other groups that some are solid and some are liquid.

# data[].attributes.body
The investigation 'making gak' researched how when you mix certain reactants, a chemical reaction occurs and a product is made. A product is a chemical that comes out of a chemical reaction and a reactant is a chemical that goes into a chemical reaction.
