Do you ever find yourself standing at the front of a classroom, pouring your heart into a lesson about cell membranes, only to see a sea of glazed-over eyes staring back? It is a tough spot to be in. You want to spark that curiosity and see those lightbulb moments, but sometimes the connection just isn't there. That is why I am so excited to introduce you to Alyse from Keystone Science.
What makes this chat extra special is that we share a very specific "past life"—we both spent years in cancer research between our teaching stints! There is something about the precision of the lab that changes how you view education. Alyse has spent years figuring out how to bridge that gap between complex lab concepts and real-world interest for older students. Today, we are chatting about her transition from the classroom to the research bench and back into the world of resources. You will find that her approach to high school science student engagement isn't about flashy gimmicks; it is about making the subject accessible, relatable, and genuinely interesting for every teenager. Let’s jump into her brilliant insights.

Connecting Science to the Real World
Bridging the Research Gap
When you talk to Alyse, you can immediately feel her passion for making science approachable. She started Keystone Science back in 2016 after experiencing the kind of burnout many of us know all too well. While she moved into cancer research—a field I know from experience requires immense focus—she couldn't stay away from education. Her core mission is making science accessible. As she puts it, "I'm incredibly passionate about making science applicable and directly relatable to students' everyday lives. While they may not be looking at cells under a microscope in their daily routines, there are aspects of that content and those skills that are important."
Making Content Relatable
She really focuses on making the content applicable to the modern teenager through her Keystone Science website. "I want to connect the science to their world and make it attainable for them to learn, access, and understand," Alyse explains. It is about taking those abstract ideas and anchoring them in something they already care about. When you can show a student why a specific concept matters to them personally, you’ve already won half the battle. This mindset is the foundation of her secondary science student engagement philosophy. It isn't just about passing a test; it is about understanding the world around them.
Think about the last thing you taught. If you had to explain to a person in the supermarket why that specific topic matters to their daily life, what would you say?

"My core mission has always been making science accessible for every student that walks through my door. I want to connect the science to their world and make it attainable for them to learn, access, and understand."
The Power of Inquiry and Collaboration
Shifting the Classroom Dynamic
If you've been looking for a way to shift the energy in your room, Alyse’s breakthrough strategies might be exactly what you need. She is a massive advocate for the inquiry-based model. This is where the students take the lead, "asking the questions and then researching or designing experiments to answer those questions." It shifts the teacher from being the "sage on the stage" to a facilitator of discovery. This naturally leads to much higher high school science student engagement because the students have skin in the game.
Building Thinking Classrooms
But she didn't stop there. She also adapted a strategy from Peter Liljedahl's Building Thinking Classrooms. "It's originally a math strategy, but it works incredibly well for science concepts—especially when you want students to make sense of data or phenomena and create models or explanations," she explains. Students work in groups of three on whiteboards to draft ideas. "Both strategies have been incredibly powerful because they give students ownership of their learning and get them talking to each other—which was especially difficult for my students post-pandemic." It gets them moving, thinking, and—most importantly—collaborating on scientific reasoning.

Struggling with cell transport? Alyse from Keystone Science shares her "secret weapon" for mastering osmosis and building student confidence through hands-on labs. @inspirationalscienceforsubs #BiologyTeacher #SecondaryScience #ScienceEngagement
Solving the Osmosis Puzzle with Hands-On Labs
The Secret Weapon for Cell Transport
We all have those topics that feel like an uphill struggle. For many, it is cell transport—specifically osmosis. You can draw all the diagrams of hypotonic and hypertonic solutions you want, but the terms often just don't stick. Alyse’s secret weapon for secondary science student engagement here is to stop talking and start doing. She found that "it doesn't matter how much I pre-teach those terms, show diagrams, or give practice—until we do an actual hands-on osmosis lab... they're not going to really understand what's happening."
From Observation to Reasoning
She uses labs with potato cubes or dialysis tubing to spark that "need to know." By starting with a mystery—like why some tubes gained mass while others stayed the same—she triggers curiosity. "Then the questions start flying: 'Why did that tube change? Why did this one not change?' It gets them really thinking about why the water moved where it did." This approach builds scientific reasoning from the ground up. Instead of memorising a definition, they are explaining a result they saw with their own eyes. It turns a dry vocabulary lesson into a detective story that actually makes sense.

The Five-Minute Connection and Smart Tools
Humanising the Science Lab
Sometimes the best way to improve high school science student engagement has nothing to do with the curriculum. Alyse uses a simple five-minute "check-in" on Mondays and Fridays. "On Mondays, we talk about what we did over the weekend. It works beautifully if I did it the Friday before because I get to check back in with students and hear how something they were looking forward to actually went." When students feel seen as people, they are far more willing to engage with the work you set for them.
Digital and Physical Toolkits
For digital tools, she swears by gamified review like Blooket. "These games keep the students that know all the answers from winning all the time!" For a physical tool, she uses a set of popsicle sticks to call on students randomly. "This allows you to engage with every student every day... students don't want to be called on without having the answer." But here is the key: if they don't know the answer, you talk them through it. "The first time or two they have to do that, they'll be more prepared next time because they don't want to be on the spot like that."

Helping Your Substitute Thrive
The Ready-to-Go Resource
We've all had those mornings where you have to call in a sub, and the anxiety is real. Alyse’s recommendation is her Feedback Loop product. "If students have the background knowledge of positive and negative feedback loops, this product shows how multiple feedback loops work in the human body." It is a brilliant resource for high school science student engagement because it is self-guided. Students read information and "identify sensors, control centers, and effectors by labeling different parts."
Differentiating for Success
The beauty of this resource is that it is differentiated. "The higher-level version has students identify which organ is the sensor, control center, and effector, while the modified version identifies those for them." It works perfectly in pairs, which keeps the students talking. "It's truly print-and-go or assign-on-Google-Classroom-and-go," Alyse says, which is exactly what a substitute needs to keep the day running smoothly. It ensures that even in your absence, the students are still developing their scientific reasoning and staying productive.
Question for your class: Think about a thermostat in a house; how is that similar to how your body reacts when you start to get a fever?

FREE Science Lesson
Ever wondered why a pot of water seems to take forever to boil, or why ice has the strange habit of floating? Alyse at Keystone Science has put together a brilliant 5-page lab guide that turns these everyday quirks into a full-blown classroom investigation.
Using two teacher demonstrations and three student-led stations, your class will collect data and compare water to other substances to see its unique properties in action.
Whether you use it to kick off a new unit or as a deep-dive investigation, it’s the perfect way to get your students thinking like real researchers.
Trusting Student Creativity
Giving the Benefit of the Doubt
Looking back, Alyse wishes she had known sooner just how capable students really are. "I wish I knew that students are way more capable and way more creative than you think." This has changed how she builds her resources. She moves away from teacher-centered lectures and towards inquiry-based activities like POGIL. "It's really important to me that students actively work with the information and learn the content in their own way so that it's more likely to stick with them."
Long-Term Impact
By trusting them to solve problems, you give them the chance to apply science to their lives. "Every student is unique, learns differently, remembers things differently, and comes to you with different life experiences. They might apply what they're learning differently because of those experiences." Whether it is through long-term projects or her free Properties of Water Lab, the goal is always the same: making the learning stick by making the student the hero of the story.
