Over the last two weeks, we have been looking at how different materials can be a solid, liquid or a gas and have been explaining how each one is different. We also made cornflour slime, which is a non-newtonian fluid which means it acts like a liquid but can become a solid when put under pressure. Other examples of this are quick sand and ketchup.
We set up our own experiments to see which type of water the ice cube would melt fastest in: warm freshwater, cold freshwater, warm saltwater, cold saltwater or on its own. We made sure it was a fair test.We found out that it took the longest to melt with no water then with the cold salt water. The fresh warm water was the quickest to melt.
We looked at other things that can melt and we did an experiment to see which chocolate melted the quickest. we found out that the white chocolate melted the quickest and the dark chocolate took the longest.
We have been learning about temperature. We know that temperature measures how hot or cold something is and that we measure in degrees Celsius. We practiced reading thermometers and tested the temperature of hot, cold and room temperatures.
We have been looking at how condensation and evaporation plays a part in the water cycle. Here is some of our work.
