Obtain a variety of doctors' tools, such as a stethoscope, a reflex hammer, an otoscope (for examing ears) and empty syringes. Lay the tools out on the floor and have a period of "free time," where students can play with the tools and try to figure out their uses. Reconvene and go through the tools, asking students what they think each is for. Explain how the tools are used. Have students choose their favorite tool and draw a picture of it or a picture of someone being examined with it.
Have students create their own doctor's kit. Have a variety of craft materials on hand for students to make their own doctors' tools.You can use simple paper lunch bags. Students can decorate the bag to make it look official. You can use Popsicle sticks, cotton balls, construction paper, pipe cleaners, glue and markers. Help students make tongue depressors, thermometers, otoscopes and reflex hammers.
This activity teaches how doctors measure weight and height. Set up a scale and a tape measure in the classroom. Have students line up and weigh and measure each student one at a time. Record the results and put them on a certificate. Give certificates to students to take home with them. Alternatively, you can display them in the classroom.
Set up a doctor's office in the classroom. Get real doctors' tools or toy versions. Make the doctor's office a permanent play area throughout the school year. Set up an eye chart, a scale in addition to having a stethoscope, tongue depressors and other standard tools. Allow one student at a time to play doctor and examine patients. Make sure you have adult supervision at the doctor's office so that children do not hurt one another.
