Physical World 1 - This outcome is associated with CW2 because a vital part of both outcomes is performing experiments which means that the students should know the suitable apparatus to use.

# data[].attributes.body
Physical World 2 - This outcome deals with looking at various terms that will be essential to CW2 such as temperature, volume and mass all elements needed for calculating solubilities and physical v chemical changes.

# data[].attributes.body
Chemical World 4 - the outcome in focus deals with separating mixtures aka solutions a concept covered completely in this outcome.

# data[].attributes.body
Earth and Space 4 - this outcome deals with developing ideas very much like how CW2 deals with developing ideas of particles and atoms.

NoS 2,3,4,5 - Each of these nature of science outcomes fall under the branch of investigating in science.Each outcome leads into the next starting with developing research questions and hypotheses to performing the experiments and lastly to reflecting on each investigation for errors and improvements.

This key skill is pivotal to this outcome for a number of reasons.Firstly a large part of this skill is gathering and recording information, also used in experimentation. Things like evaluating quality of data and organising information are essential. Also this skill needs students to be curious and to use this curiosity to probe more deeply into concepts

# data[].attributes.body
This key skill once again deals with experimentation moreso the groupwork aspect. A key part of being a scientist is co-operating with colleagues such as willing to make compromises to achieve a common goal. Learning new experiment skills with others is another key part as students are able to develop understanding and solve problems with friends.

This resource is a useful worksheet for students to complete after performing experiments that deal with solubility. Not just does it recap on the factors affecting solubility but it also involves drawing graphs and incorporates numeracy skills.

Developing literacy is another key skill in the new junior cycle and this worksheet involves developing literacy skills. I used this as trying to do a distillation experiment was out of the question due to a lack of resources. This handout described the process whilst also providing some interesting facts about alcohol distillation

Trying to link examples of physical changes and most concepts to students is difficult. I found this website and it usefully represented examples of physical changes for students to easily understand

Physical changes involve states of matter and energy. No new substance is created during a physical change, although the matter takes a different form. The size, shape, and color of matter may change. Physical changes occur when substances are mixed but don't chemically react.

How to Identify a Physical Change

One way to identify a physical change is that such a change may be reversible, especially a phase change. For example, if you freeze water into an ice cube, you can melt it into the water again. Ask yourself:

Is the change reversible? Not all physical changes are easy to reverse.

Was there a color change (with exceptions), bubble formation, or formation of a precipitate? These are all signs of a chemical change, not a physical change.

Is the chemical identity of the end product the same as it was before the change? If the answer is yes, it's a physical change. If the answer is no, it's a chemical change.

Examples of Physical Changes

Remember, the appearance of matter changes in a physical change, but its chemical identity remains the same.

Crushing a can

Melting an ice cube

Boiling water

Mixing sand and water

Breaking a glass

Dissolving sugar and water

Shredding paper

Chopping wood

Mixing red and green marbles

Sublimation of dry ice

Crumpling a paper bag

Melting solid sulfur into liquid sulfur. This is an interesting example since the state change does cause a color change, even though the chemical composition is the same before and after the change. Several nonmetals, such as oxygen and radon, change color as they change phase.

Chopping an apple

Mixing salt and sand

Filling a candy bowl with different candies

Vaporizing liquid nitrogen

Mixing flour, salt, and sugar

Mixing water and oil

Indications of a Chemical Change

Sometimes the easiest way to identify a physical change is to rule out the possibility of a chemical change. There may be several indications that a chemical reaction has occurred. Note: It's possible for a substance to change color or temperature during a physical change.

Evolving bubbles or releasing gas

Absorbing or releasing heat

Changing color

Releasing an odor

Inability to reverse the change

Precipitation of a solid from a liquid solution

Formation of a new chemical species. This is the best and surest indicator. A change in the chemical properties of the sample may indicate a chemical change (e.g., flammability, oxidation state).

Finding extra resources out of the book is hard and a lot of the time it isnt information suitable to present to students. BBC bitesize offers useful resources to include in powerpoint presentations and revision worksheets

To break up the monotony of class and theory I tried to introduce videos that deal with the concepts and are quite entertaining. This video checks the two criteria and deals with sustainable development.

I found this article/study to be most interesting as one issue I struggled with grasping was introducing IBSE into the classroom when all the students were used to traditional methods. I struggled at first with implementing this new methodology but this paper clarified concerns and is dealt with in greater detail as part of my reflection
