At third grade, students are exposed to more complex experiments and science investigations. They start to formulate their own hypotheses and interpretations on these experiments, allowing them to think more freely and independently guided by the scientific process.

Students also learn how to use numerical data and present it in graphs to study different objects and events. Students use maps and globes at this stage. Students are taught how to identify landmasses and bodies of water using these tools. Students further study the states of matter – solid, liquid and gas – and make smart guesses about their observations. Students are encouraged to repeat the process of observation and verification to ensure accuracy.

The National Science Teachers Association believes that early exposure to scientific experiment and investigation develops problem-solving skills among students, which is needed in a fast-growing technological world. Science topics for third-grade students continue to evolve to keep up with recent developments.
