It is essential for children to learn that rational thought and the scientific enterprise are based upon observations, both direct and indirect. Observations using our senses and extensions of our senses are the starting points for knowledge that reaps benefits for our daily lives and contributes to scientific understanding.

Prepare the Mystery Odor Cans and replace the lids until you are going to use them. When students are going to use the cans, take off the lids and cover the containers by placing a material square over the container and securing it with a rubber band. This will ensure that students only use their sense of smell and will also keep the substances from spilling out of the containers.
Kindergartners may need an adult to write the words on their recording sheets. If you have kindergartners whisper their answers to the adult, this will allow individuals to do their own identification of odors.
Make pairs of smell cans. Number the cans and make an answer key for yourself. Have student match the smells that are the same and record the numbers of the ones that they think match. Have the answer key available so that they can check their answers.
