Sunday Science: Making a volcano 週日科學:動手作火山

This week we’re going to make a volcano. This can be pretty messy, so make sure that you set up in a suitable area and wear suitable clothes.這一週,我們要動手做火山。製作過程可能會一團亂,所以別忘了找個合適地點,也要穿不怕髒的衣服喔!

Welcome to Sunday Science! Every Sunday during the summer, we’re going to guide you through some cool experiments that you can do at home. It’s a good idea for you to keep a record of what you do in a Science Journal. That way you can record what you learn, compare results and maybe use them to design new experiments! Have a look at the Science Journal box for some ideas to get you started. Remember to always ask a grown-up’s permission before trying out an experiment.


Making a volcano 動手作火山

What you will need:

An empty water bottle

Bicarbonate of soda (baking soda)


Dish soap

Food coloring (red)

A tray (to put everything on)

A cup or pouring jug

A spoon

A funnel (if you don’t have one at home, you can make one from cardboard covered with tinfoil or use a pouring jug to add the ingredients)

Some sand or modeling clay (optional)

Glitter (optional)

Old Newspaper

* Place the newspaper over your working surface.

* Put the tray on the newspaper. Put your empty bottle in the middle of the tray and put the funnel in the neck of the bottle.

* Use the spoon to put baking soda in the bottle. Put in enough to cover the bottom of the bottle well. If you are using glitter add this too.

* If you are using sand or modeling clay, shape it around the bottle (to about 3/4 of the way up) to make it look like a volcano or mountain.

* In the cup or jug combine 1/4 cup of vinegar, two big drops of dish soap and a couple of drops of food coloring (be careful food coloring can stain clothes).

* Pour the mixture into the bottle and watch what happens!

Next Week 下週預告

For next Sunday’s experiment you will need the following special items: A cereal box (or stiff paper), a paper or plastic cup , a balloon (a long skinny one), a long piece of fishing line (or smooth string).


Don’t forget to record what happens in your Science Journal.













* 在工作檯面鋪一張舊報紙。

* 把托盤放在報紙上。將一只空瓶子放在托盤中央,並把漏斗架在瓶子上。

* 用湯匙將小蘇打粉加入瓶內,數量要足以覆蓋整個瓶底。假如你有亮片,也可以在這時加進來。

* 假如你有沙子或黏土,將它們包住瓶子四周(約瓶高的四分之三),讓瓶子看起來宛如火山或高山。

* 在杯子或量杯中放入四分之一杯的醋、兩大滴洗碗精,與幾滴紅色色素(小心別讓色素弄髒衣服)。

* 把這些東西倒入瓶內,看看會發生什麼事!
