Activity 1:

See:

a purplish black/dark green solution was formed upon the contact of the blue solution with the aluminium foil

Effervescence was observed

There was a hole formed in the aluminium foil

A solution was collected in the glass

Think:

a chemical reaction has taken place- ionic precipitation?

Immediately and vigorously(the hole formed)

The resultant substance was collected

Wonder:

why was it so vigorous? Was it due to the identity of the substrates or the nature of the reaction?

Why did the reaction occur and how does it occur in nature?

Is there a way to cause it to be more or less vigorous(changing the identity of the metals used?)

What is the identity of the reactants and resultant substances?

Activity 2:

Explanation: The identity of the blue solution could be either copper(II) sulfate or copper(II) nitrate, as the appearance of copper(II) matches that of the blue solution, and sulfate and nitrate are soluble. Since according to the metals reactivity series copper is much less reactive than aluminium, copper ions would have been displaced by the faster-reacting aluminium ions, leading to the reaction observed and resulting in the hole formed and the change in colour of the solution/substance.

Activity 1
See: Blue solution was poured into the aluminium tray. Effervescence was observed. The solution turned from blue to black before dissolving the the tray, forming a hole.

Think: A chemical reaction between the solution and the aluminium tray took place.

Wonder: What is the solution? How and why did the solution dissolve the tray?

Activity 2
Blue solution could be copper nitrate. Aluminium is more reactive than copper, and hence the aluminium ions in the tray might have displaced the copper ions in the solution, forming copper(II) metal and aluminium nitrate.

Activity 1:
See: -there was vigorous bubbling and fizzling when the solution was ported on the aluminum cupcake tray
-a hole was formed after the solution was poured on the tray
-solution turned darker(?)

Think: -the aluminum tray has reacted with the solution.

Wonder: -what is the solution?
-why is the reaction so obvious and intense?

Activity 2:

The solution could be copper nitrate. Since copper is less reactive than aluminium, it will be displaced by aluminum to form aluminium nitrate and copper metal instead.

Activity 1:
See: A bluish-green solution was poured into an aluminium cupcake holder. In a few seconds, effervescence was observed. The blue solution turned black while bubbling and flowed into the glass cup below the aluminium cupcake holder, which had a hole in the middle.

Think: I think a chemical reaction took place with the blue solution and aluminium, thus causing a hole in the aluminium cupcake holder and allowing the black solution to enter and drop into the glass cup.

Wonder:

Was it a chemical reaction? (What kind of reaction?)

What is the blue solution?

Why did the reaction cause a hole in the aluminium?

What is the black solution at the end?

Activity 2: Explanation

Identity of blue solution—copper(II) nitrate. A displacement reaction occurred, whereby the copper in the solution was displaced by aluminium since aluminium is more reactive than copper. Thus, aluminium nitrate solution and copper metal were formed.

Activity 1: see think wonder

- See: effervescence is observed. The blue solution  reacted with the aluminium cupcake tray, forming a hole in the tray and blue solution flows into the glass. Blue solution turns black.

- Think: a chemical reaction has taken place and a new compound was formed, resulting in the change of the colour of the solution.

- Wonder: what is the blue solution? What kind of reaction was it, a displacement reaction in which the metal was displaced?

Activity 2: explanation

- The blue solution may be copper (II) nitrate. Aluminium is more reactive than copper, thus displacing copper in the compound to form aluminium nitrate and copper metal through a displacement reaction.

activity 1:

see:

a beaker of blue-green solution was being reacted with aluminium. effervescence was observed almost immediately. the reaction had caused a hole in the cupcake tray (aluminium) and resulted in a brown/dark purple solution forming which did not corrode the glass.

think:

a chemical reaction (probably due to/revolves around metal reactivity) had taken place

wonder:

what was the initial substance as well as the end product?

why and how did the reaction happen so quickly and vigorously?

The blue solution could either be aqueous copper nitrate or aqueous copper sulfate, solutions which are blue-green in nature. Copper ions in the aqueous solution were displaced by the more reactive aluminium.

# data[].attributes.body
Activity 1:
See
Green solution formed bubbles (effervescence) and turned into a darker dirtier green before turning grey and completely dissolving the bottom of the aluminium cupcake tray. The reaction caused condensation to appear on the insides of the glass.
Think
There has been a strong acid + metal reaction that caused the acid to completely dissolve the aluminium. The reaction also caused heat energy to be created.
Wonder
What caused the acid to violently react like this?
Why was there effervescence? Is it hydrogen gas?

Activity 2: The blue solution is the aqueous solution of copper(II) nitrate. As aluminium is more reactive than copper(II), copper ions are displaced by aluminium ions

# data[].attributes.body
Activity 1:
See:
- the green solution turned into a dark green/black colour upon contact with the aluminium foil.
- effervescence is observed
- the reaction formed a hole in the aluminium foil and the substance was collected in the glass
Think: the green solution reacted with the aluminium foil to produce a new dark green substance
Wonder:
- Why was the reaction so vigorous? Would the reaction be the same if another metal was used?
- What kind of reaction had occurred? Why did it occur?
- What was the initial (green) substance? What was the dark green substance produced?

Explanation:
The blue solution could be copper (II) sulfate or copper (II) nitrate. Copper (II) solution is blue in colour and fits the appearance of the blue solution. As copper is less reactive than aluminium, it would also have been displaced by the aluminium metal in a reaction, as seen in the video, hence, causing a hole to form where the reaction occured and a change in colour of the substance.

Activity 1: A blue solution was poured into an aluminium cupcake tray

See:
-Effervescence was observed
-The solution had changed in colour from blue to purplish black
-A hole had formed at the bottom of the cupcake tin
-There was condensation in the wine glass after the purplish black solution flowed into it

Think:
-A reaction between the blue solution and aluminium cupcake tray had probably occured
-The aluminium tray must be extremely reactive as the reaction was vigorous
-The reaction was a chemical reaction as the substance formed was new, having different physical properties (colour) from the initial substances and heat was produced upon the reaction

Wonder:
-What is the blue solution?
-What were the substance(s) formed?
-Why exactly was the reaction so vigorous?
-What reaction had occurred?

Activity 2: Suggest the identity of the blue solution
-The blue solution is most likely copper(II) sulfate or copper(II) nitrate. This is because firstly, these solutions are blue and fit the description of the solution seen in the video. Secondly, copper is less reactive as compared to aluminium. Hence, the copper would be displaced by aluminium resulting in the change of colour of the solution at the end and the hole at the bottom of the tin, as the aluminium displaces copper in the solution.

Activity 1: A blue solution was poured on an alumnium cupcake tray.

See: What are your observations?

After a small beaker of bluish-green solution was poured on an aluminium cupcake tray, there was an immediate chemical reaction and effervescence was observed. The violent reaction caused a hole to be formed. After the solution flowed into the glass, a seemingly brown solution/substance was formed.

Think: What do you think has happened?

I think that a chemical reaction took place after the blue solution was added to the aluminium cupcake tray to form a new substance. The reaction caused a change of state and the colour of the initial solution.

Wonder: any questions you have at the end of the video?

1) What resulted in a vigorous reaction between the blue solution and aluminium?
2) What is the identity of the new substance formed?
3) What will happen if other metal trays are used in place of the aluminium cupcake tray in this experiment?

Activity 2: Suggest the identity of the blue solution.

The blue solution is most likely copper (II) nitrate/ aqueous copper (II) sulfate/ aqueous copper (II) chloride. Aluminium is more reactive than Copper in the Reactivity Series. Therefore, the aluminium can displace the copper ions to give aluminium ions and copper metal.

Activity 1:
See:
-effervescence
-blue solution turned brown/black
-hole was formed in the cupcake tin, causing the liquid to flow into the glass underneath

Think:
I think that the blue solution reacted with the aluminium of the cupcake tin and caused a hole to be formed in the tin

Wonder:
-Why was an aluminium cupcake tin used instead of other materials?
-What caused such a large reaction to occur?

Activity 2:
Copper nitrate
Solution is blue at the start -> copper ion
Aluminium displaced the copper ions as it is more reactive

Activity 1: See, Think, Wonder

See: What are your observations?

I see a chemical being poured onto a cupcake tin which then caused a hole to be formed. There is effervescence and the colour of the chemical changed at then end of the reaction.

Think: What do you think has happened?

I think the chemical being poured into the cupcake tray reacted with the aluminium which resulted in the change on state of the metal as well as the colour of the chemical

Wonder: any questions you have at the end of the video?

Why did the reaction take place so quickly and almost vigorously? What reactants caused the reaction to be like this?

Activity 2: Explanation

The blue solution could be copper (II) sulfate or nitrate. (Blue-green solution at the start -copper) Aluminium is more reactive than copper and hence the aluminium ions displaced the copper ions.

See: what are your observations?

Effervescence is observed

A brown/black substance is formed

Think: what do you think has happened?

I think the blue solution reacted with the aluminum to form a new substance

Wonder: any questions you have at the end of the video?

What is the new black/brown substance formed.

Suggest the identity of the blue solution and explain your observations on your padlet!

The blue solution is copper chloride/copper sulfate/copper nitrate. Copper is less reactive than aluminum.

# data[].attributes.body
Activity 1: See Think Wonder
- See: There is effervescence. The reaction between the blue solution and the cupcake tray caused a whole in the base of the cupcake tray. The blue solution turned black after the reaction. There was condensation on the inside of the wine glass. The amount of time that the reaction took was also very short.
- Think: I think a new compound was formed after the reaction? That’s why the colour of the resultant solution changed? I also think that the gas produced from the reaction is water vapor, hence there was condensation.
- Wonder: What cations or anions were present that caused the reaction? Why was the reaction so quick and vigorous?

Activity 2: Explanation
- The blue solution could be copper nitrate. Zinc is more reactive than copper. Hence the zinc ions displaced the copper ions
