Science Experiment in Mrs. Clare's Class
In third grade we had a fun science experiment where my students learned to talk about the importance of making good observations in the scientific method. Students were given ice-globes, salt, sugar, magnifying glasses and flashlights. As they poured salt and sugar on the ice-globe they were encouraged to observe the difference between the two. Even though salt and sugar look identical, we observed they have different chemical compositions because one melts ice, where the other does not. This experiment then led to another important step in the scientific method, questioning.
