Valentine's day was so romantic. We had a lovely dance. The boys looked remarkably handsome and the girls were elegantly beautiful. The dance was thoroughly enjoyed by all the well-matched couples.
Bravo!!

High School Premises
The Rock Academy High School has officially moved to the new premises. We have settled in well. Parents and friends of the school are welcome to visit us!
Grade 8 Science Experiment
Test for the presence of carbon dioxide in exhaled air.
Our topic is photosynthesis and respiration. Carbon Dioxide plays a very important role in both these processes. We conducted a simple experiment to test for the presence of carbon dioxide in exhaled air.
- Prepare clear lime water by mixing a solution of calcium hydroxide and water.
- Let the solution rest until it is clear and filter all the excess lime.
- Place a straw in the lime water and exhale (breathe out) through the straw.
- The clear lime water turns milky when carbon dioxide is dissolved in it.
