Pink Bottle 01

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 with paper and pour a heaped teaspoon of bread soda into the bottle. An explosion happens! The vinegar is an acid, the bread soda is a base. When they mix they create carbon dioxide which causes a fizz or bubbles. It was great fun to watch and it was our last experiment for Science Week.

Science Experiment

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 down but the atmospheric pressure was pushing the plate up to the plastic cup preventing water from falling out. Then we tried the experiment with the glass half full of water. This time the paper plate fell off and the water fell out of the glass.

Rainbow Milk 01

This morning we did a science experiment for Science Week. For this experiment we needed food colouring, cotton wool, full fat milk, washing up liquid and some shallow plates. We had to pour the milk into the plates and let it settle. Then we poured the food colouring into the milk. We had yellow and red food colouring. The food colouring settled on top of the milk. Then we got the cotton wool and dipped it into the washing up liquid. We then held the cotton wool steady in the milk and it broke the chemical bond holding the fat in the milk together. Then the food colouring spread out into the milk and made lovely pictures and patterns. It was great fun.

Balancing Clown 01

We made clowns out of card. We had to colour them. Then we had to neatly cut them out . We also had to get two of the same coins and stick them onto the hands of the clown. Then we tried to balance the clown by the nose on our finger. We also tried balancing it on the rim of a teacup. We even tried balancing it on our nose. The way it works is that gravity is pulling it down and the lower towards the ground you put it, the easier it is to balance because the gravity is pulling it down. We enjoyed doing this experiment very much.
