Abstract Conduct experimental teaching on how to prepare iron hydroxides in the laboratory. Selecting the abnormal phenomenon of gray green color caused by complex factors during the preparation process of ferrous hydroxide, and conducting scientific exploration activities, combined with the driving force of the situation, gradually experiencing and carrying out various links of scientific exploration, paying attention to related experimental activities, fully setting up student activities, and highlighting the connection between evidence conclusions to achieve the development of scientific exploration ability.
