Last week in sixth class we watched a video on water filtration and it inspired us to do an experiment in groups on water filtration for World Water Day. We went to the organic garden and half filled jars with clay. We then added water to the jars and mixed the clay and water together. We placed a coffee filter into a funnel which

On Friday the 20th of March we had our biodiversity action day. In the morning the junior school had a power point on biodiversity. They discovered what a flower needs to grow, water, carbon dioxide and sunlight. They also looked at the life cycle of animals, insects and plants. They looked at some food chains. They identified common birds in the school yard such

In Science recently we investigated different ways of separating mixtures of liquids and solids. We discovered that mixtures like water and stones can be separated simply by decanting (or pouring). We learned that sieving is a useful way of separating a mixture like water and rice. To separate water and sand we used filter paper and funnels. This is known as filtration . Finally

Third and fourth class studied magnetism recently in Science. We began by revising the poles of the magnets and establishing the reaction when magnetic poles are placed together. Next, we tested a number of different materials to see if they were magnetic or non-magnetic. It was interesting to discover that not all metals are magnetic. Metals which are magnetic are called ferrous metals which

Third and Fourth classes studied electricity in Science. We began by learning how electricity is generated and by examining all the uses of electricity in our homes and at school. We then discussed the dangers associated with electricity and how to use electricity in a safe manner. Our first investigation was to explore different ways of creating simple cicuits using a combination of bulbs, batteries and wires.

We made crystals in class yesterday. To do this experiment you need a jar, a jug, a pencil, boiling water, some thread, a paper clip and salt. First we put some boiling water into a jug. We then poured salt into the jug and stirred it to dissolve the salt. You keep putting in salt until it stops dissolving. Then you leave the water

We are doing a food science experiment. We want to see which type of food gets bad first. We got plates and put food on them. These are the foods we put on the plates: a half eaten apple, a piece of cooked ham. some cheese, some bread, a cut grape, a melon skin and a piece of banana. We are going to observe

We did an experiment in class about the Water Cycle. You need a large bowl, a small sugar bowl, cling film and a sliotar. We put the sugar bowl into the large bowl and put hot water into the large bowl. Then we put the cling film on top of the large bowl. Then we put the sliotar on top of the cling film

Today we did an experiment for Science Week. For this experiment you need vinegar, washing up liquid, food colouring, bread soda and an empty bottle. Pour vinegar into the bottle until 3/4 full. Put a large squirt of washing up liquid into the bottle. Then we put food colouring into the bottle. Mix the ingredients together by twirling the bottle. Make a funnel

Today we did a science experiment for Science Week. For the experiment you need a paper plate, a glass and some water. We filled the glass with water to the top. Then we put the paper plate on top of the glass and turned it upside down. The water didn’t fall out of the plastic cup. This was because gravity was pushing the water
