Science is much more than memorizing vocabulary words, labeling diagrams, or recalling facts for a test. Successful science students ask questions, design experiments, collect accurate data, analyze results, recognize patterns, draw conclusions, and think critically about the world around them. These science process skills are the foundation of every biology, chemistry, physical science, and environmental science classroom.
When students enter our science classrooms, we can't assume that they are already proficient in the science process skills. Too often, we expect students to know how to read graphs, measure accurately, use laboratory equipment, interpret data tables, design controlled experiments, and evaluate evidence before they have had enough guided practice to master those skills. As a result, many students struggle, not because the science content is too difficult, but because they lack the tools they need to be successful.
After more than 30 years of teaching high school biology and chemistry, I have found that students become much more confident when science skills are taught consistently throughout the school year. Every lab, classroom discussion, graph, data table, and problem-solving activity becomes easier when students already have a strong foundation in the science process skills.
That is why I created this Science Process Skills Resource Library.
Over the years, I've written quite a few articles about teaching science process skills. This page brings together my best blog posts, classroom ideas, teaching strategies, and ready-to-use science resources in one organized location.

What Are Science Process Skills?
Science process skills are the tools students use to investigate, analyze, and understand the world around them. Unlike science facts that may be forgotten after a unit test, these are lifelong skills that students will continue to use throughout every science course they take and carry forward into their future lives.
Think about a typical week in your classroom. Your students might collect data during a laboratory investigation, measure the mass of an object, calculate density, create a graph, interpret a table of results, read an informational article, compare two biological processes, or explain why an experiment produced unexpected results. Every one of those activities depends on science process skills.
That is one of the reasons I enjoy teaching science. The content changes throughout the year, but the skills keep building. Students may begin the year learning how to read a graph or use a graduated cylinder correctly. By the end of the year, those same skills help them design experiments, analyze complex data, and communicate scientific ideas with confidence. It is an amazing feeling watching students grow, mature, and develop new skills as the year progresses.
I have learned that these skills are not mastered during a single lesson. They need to be introduced, practiced, revisited, and practiced some more throughout the school year. The more opportunities students have to apply these skills in different situations, the better science students they will become.
The sections below organize many of the science process skills that I teach in my own classroom. Each section includes articles, classroom ideas, and ready-to-use resources that will help you teach these skills more effectively.
Teaching Science Process Skills Throughout the Year
One mistake I made early in my teaching career was assuming that all of the science process skills could be taught during the first few weeks of school and then checked off my list for the rest of the year. It didn't take me long to realize the faults in my teaching strategy. Students may understand a skill during one lesson, but unless they continue using it throughout the year, many of them forget it or struggle to apply it in a new situation.
Today, I think about science process skills very differently. Instead of teaching them as a separate unit, I intentionally weave them into nearly everything we do. In all science classes, students graph data, collect measurements, analyze tables of data, compare and contrast scientific concepts, interpret diagrams, and design experiments all year long. Every time they practice one of these skills, they become a little more confident and a little more independent.
I also remind myself that every class is different. Some students arrive with strong science backgrounds, while others have had very little experience using laboratory equipment or analyzing scientific data. Taking the time to teach these foundational skills helps level the playing field and gives every student the opportunity to be successful.
Over the years, I've written quite a few blog posts about teaching these skills because they are simply too important to cover once and forget. Whether I'm teaching graphing, scientific measurement, laboratory techniques, vocabulary, data analysis, or experimental design, my goal is always the same: to help students become better scientific thinkers.

Graphing and Data Analysis
If there is one science process skill that students will use over and over again throughout the school year, it is graphing. Whether they are studying enzyme activity, population growth, heating curves, the periodic table, or biochemistry, students are constantly collecting data and looking for patterns.
Unfortunately, graphing is also one of the skills that many students find intimidating. Over the years, I've learned that the problem usually isn't creating the graph itself. The problem begins with identifying independent and dependent variables. The next challenge is helping students understand what the graph is trying to tell them. A beautifully drawn graph isn't very useful if students can't explain the pattern, identify an outlier, or form a conclusion based on the data.
That is why I don't treat graphing as a one-day lesson.
Instead, I introduce the basics early in the school year and then continue using graphs in laboratory investigations, class discussions, homework assignments, quizzes, and review activities. Every time students graph a new set of data, they become a little more comfortable with the process.
I also encourage students to ask questions every time they see a graph.
- What pattern do I notice?
- Is there a trend?
- Are there any unexpected results?
- What conclusion can I draw from these data?
- If I repeated this investigation, would I expect similar results?
Those questions are far more important than simply drawing straight lines or choosing the correct scale.
If your students struggle with graphing, don't get discouraged. Like every science process skill, graphing improves with repeated practice. By the end of the year, students who were once nervous about graphs often analyze them without even realizing how much they've improved.
Below are several articles and classroom resources that will help you teach graphing and data analysis throughout the school year.

Scientific Measurement
One of the first laboratory skills I teach every year is scientific measurement. It doesn't matter whether students are using a balance, graduated cylinder, metric ruler, thermometer, or pipette. They need to understand that accurate measurements are the foundation of good scientific work.
Students often arrive in high school with very different backgrounds. Some have measured mass and volume many times, while others have had very little hands-on laboratory experience. I've learned not to assume anything. Taking a few extra days to teach measurement correctly at the beginning of the year saves a tremendous amount of frustration later.
One mistake I see over and over again is that students rush through measurements. They estimate instead of carefully reading the scale, forget to record units, or are just sloppy using pieces of lab equipment. Those may seem like small mistakes, but they can completely change the results of an investigation.
Rather than teaching measurement as an isolated lesson, I intentionally build it into laboratory activities throughout the year. Students measure volume, mass, temperature, length, collect quantitative data, and practice using metric units in dozens of different situations. Before long, using metric measurements becomes second nature.
Scientific measurement also gives us the opportunity to reinforce other important science process skills. Students learn to organize data in tables, calculate averages, identify sources of error, calculate the percentage error, and decide whether their measurements are reasonable. Those conversations often become just as valuable as the laboratory investigation itself.
If your students need extra practice with metric measurement, don't wait until they struggle during a laboratory investigation. Giving students opportunities to practice before they need the skill builds confidence and makes later labs run much more smoothly.

The Scientific Method and Experimental Design
Ask ten science teachers what the scientific method is, and you'll probably get ten slightly different answers.
For me, the scientific method isn't about memorizing a list of steps. It's about teaching students how to APPLY the scientific method. It's about teaching students how to think.
Students need to learn how to ask good questions, make careful observations, develop logical hypotheses, identify variables, design controlled investigations, collect reliable data, and draw conclusions that are supported by evidence. Those are skills they will use long after they forget the details of a particular biology or chemistry unit.
One challenge I see every year is that students often want the "right answer" before they have collected any evidence. Science doesn't work that way. Good scientists gather evidence first and allow the evidence to guide their conclusions. Helping students become comfortable with uncertainty is one of the most important lessons we can teach.
I also spend quite a bit of time teaching students to distinguish between independent and dependent variables. It is the foundation of a controlled experiment, and for some reason, students need to practice this over and over.
As the year progresses, students begin applying the scientific method without even thinking about it. They naturally identify variables, recognize weaknesses in experimental design, suggest improvements, and explain unexpected results. Watching that growth is one of the most rewarding parts of teaching science.
Remember that students don't become skilled at experimental design after completing one worksheet. Like every other science process skill, it improves through repeated practice in many different contexts.

Laboratory Skills and Safety
When I think back to my first few years of teaching, one thing stands out very clearly. The laboratories that ran the smoothest were not necessarily the most exciting labs. They were the ones where students knew how to work safely, use equipment correctly, and think through each step before they started.
Laboratory skills are much more than learning the names of equipment. Students need to know how to read a graduated cylinder, use a balance correctly, focus a microscope, handle chemicals safely, dispose of materials properly, and work cooperatively with their lab partners. Those skills don't happen automatically. They need to be taught, modeled, and practiced.
I also remind my students that making mistakes in the lab provides opportunities for learning. If a balance isn't zeroed correctly or a measurement is recorded incorrectly, we talk about how that affects the results. Those conversations help students understand why careful laboratory technique matters.
One of the biggest changes I've made over the years is slowing down during the first few weeks of school. I used to feel pressure to get into the "real biology" or "real chemistry" as quickly as possible. Now I know that investing time in laboratory skills early pays dividends for the rest of the year. Students become more independent, ask better questions, and require much less individual assistance during future investigations.
Another lesson I've learned is that students enjoy labs much more when they feel confident. If they understand how to use the equipment before beginning an investigation, they spend less time worrying about making mistakes and more time thinking about the science.

Reading, Writing, and Thinking Like a Scientist
Science teachers have to be reading teachers.
Every year my students read laboratory procedures, scientific articles, graphs, diagrams, tables, textbook passages, and science-related articles. If they struggle to read scientific information, they will struggle with nearly every science topic we teach.
Scientific reading is different from recreational reading. Students need to slow down, examine diagrams, study captions, interpret graphs, and connect information from multiple sources. Those are skills that improve with practice.
One strategy that has worked well in my classroom is teaching students how to actively interact with scientific text instead of simply reading words on a page. I encourage them to highlight unfamiliar vocabulary, write questions in the margins, summarize sections in their own words, and constantly connect new information to concepts we have already studied.
Writing is equally important. Asking students to explain their thinking often reveals misunderstandings that multiple-choice questions never uncover. Short written explanations, laboratory conclusions, CER activities, and open-ended questions help students organize their thoughts while strengthening both science and literacy skills.
Helping students become stronger readers and writers doesn't take time away from teaching science. It helps students understand science more deeply.

Building Scientific Vocabulary
Science vocabulary! The gargantuan volume of new science terms and definitions can be overwhelming for students.
I still remember students telling me that biology felt like learning a foreign language. After hearing that enough times, I realized they weren't exaggerating. Every chapter introduced dozens of new words, many of which looked intimidating before students even attempted to pronounce them.
Instead of asking students to memorize endless vocabulary lists, I spend time teaching prefixes, suffixes, and root words. Once students understand that "photo" means light or "hydro" refers to water, they begin recognizing patterns instead of memorizing isolated definitions.
One of my favorite moments is when students start figuring out unfamiliar vocabulary on their own. They begin breaking words apart and using what they already know to predict meanings. That confidence carries over into every unit we study.
Vocabulary instruction shouldn't end after the first week of school. Students continue building their scientific vocabulary all year long, and every new term becomes easier once they recognize the patterns behind the language.

Compare and Contrast
One skill that doesn't receive enough attention is comparing and contrasting.
Science is full of similarities and differences. Students compare mitosis and meiosis, prokaryotic and eukaryotic cells, physical and chemical changes, aerobic and anaerobic respiration, dominant and recessive traits, and countless other concepts throughout the year.
Many students naturally notice differences but struggle to identify meaningful similarities. Others create long lists of facts without recognizing the important relationships between concepts.
I have found that graphic organizers, Venn diagrams, comparison charts, and guided questions help students organize their thinking. Instead of memorizing isolated facts, students begin seeing connections across units and recognizing recurring scientific themes.
Compare-and-contrast activities also encourage higher-level thinking. Students move beyond remembering information and begin analyzing, evaluating, and explaining relationships. Those are the types of thinking skills that prepare students for more advanced science courses.

Collaborative Learning Lab Stations
Some of the best conversations in my classroom happen when students are working together.
For many years I relied heavily on traditional worksheets when introducing science skills. Students completed the assignment, I graded it, and we moved on. While that approach certainly has its place, I eventually realized that students learned much more when they had opportunities to discuss, question, and solve problems together.
That realization eventually led to the creation of my Science Chat activities.
Rather than sitting quietly and completing another worksheet, students move around the classroom, discuss ideas with their classmates, solve problems together, and help one another master difficult concepts. The room becomes much more active, and students become much more engaged.
Science Skills Chat has become one of my favorite beginning-of-the-year activities because it introduces many of the foundational skills students will continue using throughout the year. Students practice graphing, laboratory equipment, scientific notation, measurement, data analysis, and scientific thinking while working collaboratively.
Collaborative learning isn't just more enjoyable for students. It also encourages communication, critical thinking, and problem-solving skills that scientists use every day.

Final Thoughts
If there is one piece of advice I could give to new science teachers, it would be this: don't rush through science process skills.
It can be tempting to jump straight into cells, genetics, chemical reactions, or ecosystems because those are the topics students often associate with science class. But the time you invest in teaching graphing, measurement, laboratory skills, vocabulary, data analysis, and scientific thinking will make every one of those content units more successful.
I've watched thousands of students grow as scientists over the past three decades. The students who experience the greatest success are rarely the ones who memorized the most facts. They are the students who learned how to ask questions, analyze evidence, communicate their thinking, and solve problems.
Those are the skills that last long after students leave our classrooms.
I hope this Science Process Skills Resource Library gives you new ideas, saves you planning time, and encourages you to keep teaching these foundational skills throughout the school year. Feel free to bookmark this page and return whenever you're looking for fresh ideas, classroom activities, or new resources. I'll continue updating it as I publish new articles and create additional science process skill activities.
Happy teaching!
