Germination

Our science topic this term is germination. Just like humans, plants need certain things to grow and survive. We have been learning about plant growth and survival, parts of a plant, methods of seed dispersal and how plants make their own food through a process called photosynthesis. We decided to plant and grow our own plants. We used soil, seeds, biodegradable pots and water and have enjoyed watching their growth and progress in class. Keep an eye on our blog for an updated photo of our class planters. 💐🍃🪴

Electricity

Our science topic this term is Electricity. We discussed the dangers of using electricity and ways in which we can stay safe when using it at home or at school. We designed posters to be displayed in the school infants corridor as we felt that the younger pupils in the school might not be as aware of the dangers as we are.

We have also been learning to combine components to make an electrical circuit. We learned what symbols represent each component in a circuit and used these to draw a circuit for a torch. After learning how to draw a circuit, we practised making one. We used wires, batteries, bulbs, buzzers, motors and switches. We enjoyed working in groups to combine our circuits and make even bigger ones. It is important to remember that if there is a break in the circuit, it will not carry the electricity through. 🔋⚡️💡🔌

Lung models

As part of our human body topic, we learned about the lungs and the respiratory system; the group of organs and body tissues associated with breathing. We took part in different types of exercise to see the effect this would have on our breathing.

Next we made a model of the lungs using a plastic bottle and balloons.

The balloon at the bottom works like your diaphragm—a strong muscle that expands and contracts to cause your lungs to fill with air and then empty out again. The movement of the balloon matches your breathing – when you breathe in, your lungs fill with air just like the balloon inside the bottle did. That’s because the diaphragm expanded making room for air inside the lung. When you breathe out, your diaphragm contracts (or squeezes in) pushing all the air out of your lungs. 🎈🫁😮‍💨
