Today, we finished studying Biology for our Junior Cert.

Biology teaches us about life on our planet.

Our teacher asked us what we had learned….

We told him that we learned about cells…by looking at them under a microscope.

Then, our teacher asked…….

“What types of cells did you study?”

Sean answered, “we studied red blood cells in the human body”.

“They’re the ones that carry oxygen”, Megan added.

“Yeah, and the white blood cells fight disease”,said Declan.

“What else does our blood carry?”, our teacher prompted.

Graham replied, “It carries the food……that we break down in our digestive systems”.

“This is how all our cells get energy from our food”, Kathy offered.

We take in oxygen throughour lungs!

We use oxygen to get the energy from our food and excrete carbon dioxide.

Our teacher reminded usthat this was called…

RESPIRATION

“Consumers get energy from producers through a food chain,”, Nicole remembered.

“Producers make food with the help of chlorophyll, sunlight and carbon dioxide”, Megan added.

“This is called photosynthesis”, finished Eoin.

“Plants use flowers to reproduce”, said Niamh.

“The pollen can be broughtto the stigma by insects orby the wind”, Laura offered.

“Once the egg is fertilised, a seed develops which can be dispersed”, whispered Sean.

“Animals also use fertilisation to make new life”, reminded our teacher.

“Males produce sperm in the testes”, Declan smiled.

“This sperm fertilizes an egg, which will eventually become a baby”, stated Kevin.

“What is the purpose of fertilisation”? our teacher asked……

…..We hesitated….

Until finally, Eoin replied that it allows both parents to pass on genes to their children.

“Why is it important to pass information to the next generation”? our teacher asked……

“So that they can survive”, we replied together.

Our teacher smiled, which wasn’t always a good sign. “Give me an example”, he asked.

Kevin was ready. “A desert plant needs to have the right things to be able to survive dry conditions”, he said confidently.

“Yeah, like good roots to anchor it”, said Laura.

“However, sometimes we can interfere with nature by adding unwanted wastes into our environment”, our teacher offered.

“This is called POLLUTION”, we chanted together.

Science Differentiation in action

We know that nature is beautiful and provides us with many things, such as food, shelter, medicine, clothing and leisure.

It is a pity to destroy it, we decided.
