Matter Chef Post By Amy

Last term, 3/4W participated in an activity called Matter Chef. It was just like Master Chef. We had a mystery ingredient which was an egg. We had 5 minutes at the pantry, 10 minutes to put together our ingredients, and 10 minutes at the Matter chef frying pan. We had judges taste our food, which was delicious. We made food like pancakes and toast, with toppings of peaches and chocolate. Here are some photos of 3/4W making their dessert:

3/4W’s Awesome Science Experiments

This term, 3/4W have been doing a variety of experiments. At the start of the term we did an experiment with ice to see how long it would take to melt. We then did this experiment again because we found that when we first did it, it was not a fair test.

This is some of our reflections after doing the first ice experiment:

The ice melting experiment number 1

It’s not fair because some people got the ice before others.

It’s not fair because some people got bigger bits or more ice than others.

It’s not fair because some people did different things with the ice like putting it on the finger, the hand or sucking it.

It’s not fair because some people were in the shade and some people were in the sun.

How could we make it a fair test?

Start at the same time by taking the ice at exactly the same time. We will put ice on the table so that everyone can get it at the same time.

Getting ice of the same size.

Making sure people are in the same environment or place or weather.

Everyone put the ice on your palm. If people are putting it on different areas of their body or hand than the ice might melt quicker or slower.

We will have only one person to do the timer and we will use an online stopwatch.

We found out that most ice blocks melted after 9 minutes. However, another class found most of theirs melted after 5 minutes. We think this might be due to the weather.

Something that is difficult to change

Everyone’s hands are different temperatures.

These are some pictures and steps for our other experiments.
