In today’s classrooms, you’ll see an emphasis on science, technology, engineering, and math (STEM). Educators and administrators are having discussions about how to prepare their students and ensure they have the skills to be successful in our technology-driven world. There’s no denying that technology has changed the workforce and classroom. A report from the Institute for the Future and Dell Technologies estimates that 85% of the jobs that today’s students will be doing in 2030 haven’t been created yet. Currently, 20% of U.S. jobs require significant STEM knowledge and skills, according to STEMconnector. While students are still in the classroom, it’s important that they’re provided the opportunity to learn the skills they need for the growing and changing demands of the future.
Incorporating STEM in the 4 Cs
The four Cs of 21st Century Skills have been making their way through classrooms as the key pillars that students must know how to do in order to be successful in today’s workforce. It’s especially important that students engage in activities that require skills they may need for jobs in the local workforce.
1. Critical Thinking
You can promote critical thinking by presenting a science problem to your students, such as a phase change of a substance. Ask them to predict the temperature change during the phase change and to explain why they made that prediction. By having students observe a scenario and predict the outcome, they can form hypotheses about what they think will happen based on prior knowledge. Using data-collection technology, students can collect and analyze data to test their hypotheses and plan their next steps.
Encourage students to think differently. First, ask students questions about science phenomena and discover what prior knowledge they already have. Ask them to apply that prior knowledge to a different reaction or phenomena and test their ideas. With data collection students can use their creativity in a more efficient way. They can gather data quickly and repeatedly in order to compare the data and test their ideas.
These days it is rare for individuals to work alone, whether it’s in school or in their future careers. Science labs and experiments are a perfect opportunity to have students work together in groups to solve a problem. Assign roles within a group, or have the group determine how they’d like to solve an experiment. Foster a collaborative environment and encourage students to learn skills from others to help them complete the task at hand.
Create opportunities for students to present their findings to the class. Have them clearly communicate what they thought would happen, the steps they took during their investigations, and what they discovered, along with the data to back up their findings.

Teaching can be a challenge, but budgeting to teach is often a downright pain. Teachers not only face small budgets and limited time to plan out their classrooms each year, but often deal with sudden “use it or lose it” funds with little advance notice. Confusing planning strategies, unclear budget allocations, and stretched resources can make it difficult to plan a budget for their classroom that’s both realistic and meets their needs.
Join members of the Scratch online community on May 11th as they come together to share, create, and expand on new ways to utilize Scratch programming. We make it easy by providing a free fun activity.
Understanding block-based programming languages like Scratch is an important skill for 21st century students to have, but it can be difficult to find resources to teach it successfully. As an Engineering Education Technology Specialist at Vernier, I help teachers bring block-based programming into their classrooms. It can be taught at all levels—from elementary to college—and can be used across disciplines, including computer science, math, social studies, music, and even art.
National DNA Day is on April 25th. This is an excellent opportunity for you to discuss the importance of DNA and to introduce the topic of gene expression in your class. As a former instructor, I found that there were very few lab activities that investigated gene expression. Most DNA activities were classic DNA precipitation or biotechnology cloning activities. While these activities are great for learning about DNA and biotechnology, one of the key concepts that I wanted my students to understand was gene expression. To this end, I worked with Bio-Rad Laboratories and my friend Dr. Roy Ventullo, a college professor and microbiologist, to develop a unique way to look at gene expression using fluorescence with our SpectroVis® Plus Spectrophotometer.

Introducing new technology into your classroom can be a significant undertaking. Creating new lessons and incorporating new platforms can require you to learn new technology, figure out how to incorporate it, test it, and then implement it with your students.
Earth Day is a perfect opportunity to get your students engaged in a conversation about conservation and sustainability. By incorporating hands-on activities and experiments that take place beyond a book into your curriculum, you can help your students connect the dots between the lab and the real world. When your students visualize data through real-world applications, they are better able to understand the root causes behind issues and engage in critical thinking.
It can be challenging to engage students in science activities, despite how exciting the lessons are. As an Education Technology Specialist at Vernier Software & Technology, I frequently receive phone calls and inquiries from elementary teachers looking for ways to engage their students with hands-on science experiments. Teachers are tasked with teaching an array of subjects, and as a result, many find themselves teaching science despite not having the experience to describe complicated and seemingly intimidating concepts in an effective and stimulating way. After years of attending and conducting workshops with teachers of all levels, and being a former science teacher myself, I know this to be an especially significant challenge for teachers.
Do you teach force and motion? Equipped with a load cell to measure force and both an accelerometer and gyroscope to measure motion, our Go Direct® Force and Acceleration Sensor is perfect for hands-on science activities. Drag a sneaker across the floor to study friction, or tie Go Direct® Force and Acceleration Sensor to a string and swing it around your head to investigate circular motion. Incorporate the sensor in your LEGO® machines and measure the mechanical advantage of levers and ramps.
Martin and his physics students at Hellgate High School in Missoula, Montana, used the VSMT to investigate the tensile strength of a variety of different pencils, as well as different kinds of popular fishing knots. Martin decided to use the local interest for fly fishing to introduce engineering applications for testing and design. After collecting data with the VSMT, students determined which knots for fishing were best to use in terms of strength.
“Vernier Structures & Materials Tester is truly a piece of engineering elegance. It looks amazing sitting in the classroom and no doubt will inspire innovation and creativity by its mere presence. And its good looks are just the beginning. The dynamics of operation also share the elegance. Using two sensors in tandem, the Vernier Structures & Materials Tester measures both force and displacement. The force sensor has a range from zero up to 1000 newtons with 1 N resolution. And the displacement sensor will measure at tenth-millimeter resolution a distance up to seven centimeters.”
“So now when I see interesting light bulbs and light sources, I try to imagine what the wavelength spectrum looks like. And given the rapid evolution of LED lights and light applications, I cannot easily think of a limit to the educational applications of the Vernier Go Direct® SpectroVis® Plus Spectrophotometer.”
In another investigation, Martin used the Go Direct® SpectroVis® Plus Spectrophotometer to teach his students about the transmission and absorption spectrum of a fluid. After preparing the liquid using isopropyl alcohol and a kale leaf, the class used the spectrophotometer to view and investigate the sample’s absorbance spectrum. Martin then engaged students in a whole-class discussion about the findings, in which he said:
“While running this analysis projected onto a large screen with a classroom full of students, I posed the question of what would the spectrum curve look like for transmittance, or reflectance, as we like to think of it. A student slowly approached the whiteboard with the giant projected absorbance spectrum curve and tentatively plotted some data points opposite the existing graph. As the mental gymnastics went into overtime, it was clear that the undeniable inverse within science was inescapable. The reflectance could be nothing other than the opposite of the absorbance.”
With the Go Direct® SpectroVis® Plus Spectrophotometer, students can easily and wirelessly collect a full wavelength spectrum—absorbance, percent transmission, or intensity—in less than one second. The spectrophotometer can be used in a variety of spectroscopy experiments including determining the peak wavelength to collect data on solution concentration for studies of Beer’s law or to monitor rates of reaction; collecting a full wavelength spectrum to measure absorbance, percent transmittance, fluorescence, or emissions; conducting enzyme kinetics experiments; and more.
