STEM Week (Science, Technology, Engineering, Maths)

Good morning everyone, buenos dias a todos.

This is St Joseph’s STEM week and Miss Clark will be posting lots of interesting STEM activities on Twitter for you to try throughout the week. Here is some information about STEM Share. Look down this page and you will see a science activity to try with raisins!

Here is activity #1 (science)

Bobbing Raisins
Note: This activity can be done with regular
household items, but don’t forget to ask an adult to supervise. (This experiment is from
www.kids-science-experiments.com)
TOPIC
Gas Release
SUPPLIES
• Clear glass jar
• Carbonated drink (clear possibly lemondade)
• Handful (4-6) of raisins
INSTRUCTIONS
1. Pour the carbonated drink into the glass jar
2. Drop the raisins into the glass jar
WHAT HAPPENS?
WHAT CAUSES ALL THE ACTION?
The bobbing up and down happens because
the bubbles of the carbon dioxide gas in the
drink are much less dense than the drink or
the raisins.
Once the raisins start bobbing up and down, they
continue to rise and fall for about an hour.
• Raisins are denser than the carbonated
drink, so they will sink.
• Gas bubbles attach to the wrinkles on
the raisins.
• When the raisins are covered with the
bubbles they become less dense than the
drink, so they start to rise.
• The gas bubbles start bursting and then the
raisins become denser than the drink, so sink again.

Literacy
