Golden Syrup!

I can’t eat it!

The Year 8’s had an awkward day at Technicraft, not just unusual but awkward, it included golden syrup, a methylated spirit burner, matches, safety goggles and test tubes. The  objective was to observe if the smell of the golden syrup increased and melted faster while in a solid and frozen form inside a test tube.

In its solid state, the smell of the syrup wasn’t really noticeable. Placing the test tube with the golden syrup inside it, underneath the armpit for 1 minute and then taking it out -  the syrup actually melted but not as fast as had been predicted. Using a hand motion to allow the aroma to waft into the air increased the sweet smell further.

Following that, rubbing the test tube in between our hands, the smell increased more together with the speed at which it melted. Every time something different was tried, there was a minimal change that affected.

Eventually, the burner was lit and  the test tube (held by test tube holder), was cautiously held above the flame and rotated.  Bubbles started to sizzle. Close observations showed the bubbles in the syrup began to form  rings down the test tube, which was fascinating.

Observing the changes that occurred when the golden syrup was heated was a fascinating and inspiring experience.

Which bubble is going to last the longest?

The time is ticking!

At Technicraft year 8 experienced an interesting group of lessons, involving making and testing 6 different substances to figure out which one (Glucose, glycerine, salt, sugar, water or detergent) would allow bubbles to last the longest without dehydrating and evaporating.

The glycerine had a lot of  viscosity (syrupy)  and was  transparent. Observations were like syrup  but white in colour.  When poured into a cup, the smell was a bit hideous.

5 cups and a plastic straw including a timer were part of the experiment to observe how long a bubble lives when it’s blown out of the straw. The detergent is combined with water and then poured  into the cup.

Following that as the salt, water and detergent were trialed and also timed. Unfortunately the bubble did not last very long (less than a second.) Salt does not create bubbles!

Later on, after testing all the substances and looking at the time they lasted. Unfortunately salt was the least bubble to stay the longest because salt can’t make a bubble. The glycerine should’ve lasted the longest, but  it was the sugar that proved to be most effective in sustaining the life of a bubble.  This result however, was very unusual.

To get long lasting bubbles, I recommend that your bubble mixture should include: glycerine, water and detergent.

Acrostic Poem!

Inside a Bubble!

Inside a Bubble!

As I record my day at Tech, the Year 8’s experienced the bubbles inside each other.

Materials:

Straws

Container with solution(Water, Sugar, Soap)

Method:

Pour the detergent gently into the solution (soap, water and sugar) and stir until the sugar has dissolved. Use 3 fingers and dip it into the solution and spread it in front of you on the table so that the bubble doesn’t dehydrate and evaporate.Following that use a straw and immerse it towards the solution to enable the breath that’s coming from your mouth to create a bubble. The goal is to make a bubble inside another.

Conclusion:

The result turned out to be 7 bubbles inside each other. The experiment was that we discovered how long it takes for a bubble to last and expand their sizes.

The liturgy of the Eucharist!

The Liturgy of the Eucharist is part of the Easter Vigil celebration during a catholic mass. During Mass, the priest blesses the Eucharist an people who have received the Sacrament of Holy Communion receive the Body and Blood of Christ.
