This year, along with Ms. Tracey’s Snr Infants, we are working towards achieving an SFI Certificate in Stem! That means LOTS more hands-on Science and Maths for us during this term.
Last week we combined Geography, Science, English and Art in learning about Volcanoes.
In Geography we learned about different types of volcanoes and saw them in action in this video
We also learned about the parts of a volcano:
We learned the poem ‘The Volcano’ in English with lots of descriptive words! We counted all the descriptive words used and responded to the poem. We then shared our favourite lines with each other.
In Art we looked at the construction strand and made our volcanoes using the paper maché technique!
To make a volcano in groups we needed:
- A small plastic drinks bottle (without lid) we used a Fruit Shoot bottle!
- Newspaper from Aldi
- White glue
- A bowl
- A large cardboard box
We created our constructions through layering the newspaper around the bottle making sure to keep the top of the bottle clear. We used the following method:
- Cut a large square out of your cardboard box to make the base board.
- Using white glue, stick the bottom of the drinks bottle to the base board.
- Rip half of the newspaper into inch-wide strips.
- In a bowl, put some white glue.
- Scrunch up sheets of the remaining newspaper, submerge it in the glue mixture and stick it on to the cardboard around the base of the bottle.
- Continue to use scrunched-up newspaper to build up the volcano around the sides of the drinks bottle.
- Next, dip strips of newspaper into the glue mixture and lay them on the top of each other, covering the scrunched-up paper, from the bottle opening to the cardboard base.
- Add several layers of torn paper until the shape resembles a volcano.
- Leave to dry for at least 24 hours.
Once our volcanoes were dry we brought them outside for a Science experiment. Miss Diskin told us about chemical reactions and how, using our volcanoes we could create one. We learned that when you add vinegar to bicarbonate of soda a chemical reaction occurs – the result is ‘carbonic acid’. This is an unstable substance – you can tell from all the fizzing! The mixture instantly separates into a gas and a liquid, producing carbon dioxide and water. Check out our pictures of this fun and safe experiment.
All we needed was:
- Bicarbonate of soda (also known as “baking soda”; not “baking powder”)
- Red food colouring (optional)
- Add two or three tablespoons of bicarbonate of soda to the bottle in the centre of the volcano.
- Next, add a couple of drops of red food colouring.
- Finally – get ready for your volcano to erupt – and add the white vinegar!
Keep your eye out for more hands-on experiments soon!
