Hygiene is a condition in which health is maintained and diseases are prevented. This is a simple definition of hygiene, yet a bigger understanding is able to be obtained. For many, only the basics of hygiene are considered, such as brushing teeth and washing. However, instead of emphasizing these routine practices, skill sets can be created to combat more issues regarding hygiene which in turn leads to knowledge that lets people know that a lack of conscientiousness contributes to many of the misunderstanding within hygiene. If an awareness can come about with regards to hygiene, then people will know to not only always prepare their food adequately before consuming, but to still keep in mind the other aspects of hygiene that are often forgotten or not thought of as much. All of this creates the full realization and makes sure that health is always maintained and disease and lingering bacteria is prevented as much as possible.

Practical scientific literacy cannot be undermined in education. In schools, practical literacy prepares students for strong social involvement as well as provides an opportunity for a wide range of employment options. Practical literacy fosters additional education by cultivating an attitude of lifelong learning. This form of literacy connects knowledge attained in schools to individual lives. Students are able to apply what they learned in educational settings to diverse aspects of life, allowing individual growth. 

Hands-on experiments and real-world problem solving are used in the classroom to promote practical scientific literacy. Cal Poly’s slogan, Learn by Doing indicates practical literacy as the educational model's focal point. Rather of assessing students only on theory, teachers frequently give projects that require students to address real-world problems and connect theory to applications. (Sorvik 275). For example, in engineering, one would be asked to build a basic machine. The project would challenge them to use theoretical principles learnt in the classroom, such as components of physics, to create a machine that fulfills a practical function. This hands-on project reinforces academic information while also demonstrating the student's ability to apply scientific ideas to real-world challenges.

Outside of the classroom, actions such as research participation, scientific problem solving, and participation in science-related hobbies reflect practical scientific literacy. Some individuals, for example, contribute to biodiversity monitoring by recording and sharing observations of plants, animals, and other living species in their local surroundings using platforms such as iNaturalist. Users can upload photographs and information about a bird, a wildflower, or an insect, which are then added to larger databases used by specialists for ecological research and conservation efforts. (Loarie np). This hands-on approach to nature allows a diverse group of people to explore and appreciate the variety around them while also actively participating in research endeavors. These experiences allow individuals to apply scientific ideas in real-life circumstances, resulting in a more educated and informed population.

Practical science literacy applies to understanding representations of data. For example, the chart to the left, adapted from the statistical data company Statista, shows how long a computer would take to guess passwords based on their complexity (Buchholz, np). To increase the complexity of a password, it must include characters from a more extensive set, such as lowercase letters, uppercase letters, numbers, and symbols. As the number of characters in a password increases linearly, the number of possible combinations increases exponentially. Readers demonstrate practical literacy by realizing that long passwords with various characters are complicated for computers to crack and adjusting to this criteria to improve their digital security. In this case, applying practical literacy protects readers’ personal information, such as government identification numbers and bank account credentials.
