YUMMY FOOD !!!

Today at Enrich I did science and we made FOOD! First we made bread. We had to make the dough first, and leave it so that the yeast would work with the warm water and start the reaction. While that was happening, we made sherbet. We had to taste-test each ingredient: Icing Sugar, Raro, Baking Soda, Citric Acid and Tartaric Acid. We had to comment on what each one tasted like:

Icing Sugar: Sweet

Raro: Orange, Sweet and Sour

Baking Soda: Sour

Citric Acid: Sour

Tartaric Acid: Yuck!

The last thing we made was hokey pokey. We melted golden syrup and sugar until it boiled. We added baking soda, which made the mixture bubble. We put it in the freezer to set.

I have been impressed with your enthusiasm during our science talent development. You are becoming more confident to join in our discussions, as you always listen with interest to others. You clarify anything that you are unsure of by asking questions - it is so important that you continue to do this when learning new concepts. You worked well with Jordan last Thursday to make your own lava lamp. This reaction was instant and you were able to make connections from the previous week with our floating currents activity. You have worked well throughout the term on your Must Do and Picks sheet - you have made great progress with your time management. Well done Bede.

Science - Lava Lamps

This morning for science talent development, we made lava lamps. We needed the following:

An empty bottle

Water

Cooking Oil

Food Colouring

2 x Vitamin Tablets

You fill the bottle with 1/4 water. You then add the oil until almost the top of the bottle. You wait for the water and the oil to separate. You add 12 drops of food colouring. (Dark colours were not my favourite). You add in the two vitamin tablets and wait for the bubbles to start!

The vitamin tablets have baking soda and citric acid in them - they react with the water to start the bubbling. The oil and water will not mix, so the bubbles take the food colouring up into the oil and then they sink back down to the water. This happens until all the CO2 gas is gone.

Balloon Blow!

Today we did science. We looked at experiments with baking soda and vinegar. My favourite experiment was the balloons. We poured vinegar into a empty bottle, and then using a funnel we put 3 tsp of baking soda into a balloon. We attached the balloon to the top of the bottle, then tipped the balloon upside down, so the baking soda mixed with the vinegar. The gas produced then blew up the balloon. Jordan and I took our balloon outside and we popped it with a pen! It was a really fun session today.

Science Talent Development.

Today we did two experiments they both involved ice. One was to see which one would melt the quickest we had three ice cubes each. One was raro and another one was a sugary cube and a plain water one. Raro was first Sugary was second and plain water was third. And then we did another experiment was similar but one ice cube with salt another was an ice cube with sugar and one was with nothing. Sugar was first salt was second and plain water was third, and both of my hypothesis's were wrong.
