STEAM Unit: The Science and Math Behind Beverage Syrups—Viscosity, Ratios, and Scaling Up Production

Hook: Turn limited prep time and tight budgets into a delicious STEAM lab

Teachers, students, and lifelong learners: if you struggle to find affordable, standards-aligned, hands-on lessons that combine math and chemistry, this STEAM unit is built for you. Using a simple syrup lab inspired by the DIY growth story of Liber & Co., this module teaches ratios, density, viscosity, scaling math, and basic food chemistry with low-cost materials and classroom-friendly safety practices.

The big idea — why syrup is a perfect cross-curricular project in 2026

In the last two years (late 2024–2026) education has doubled down on experiential learning, micro-credentials, and community-industry partnerships. Food science and maker-style labs are especially powerful because they connect sensory experience with measurable data. A syrup unit lets learners:

• Bridge math (ratios and proportional scaling) with science (viscosity and density)
• Practice lab habits—protocols, safety, data collection—without expensive equipment
• Explore entrepreneurial thinking by modeling scale-up from a kitchen batch to commercial tanks

"It all started with a single pot on a stove." — the founders of Liber & Co., a real-world example of scaling from hands-on experimentation to 1,500-gallon tanks.

Unit Snapshot: Objectives, time, and materials

Learning objectives

• Math: Use ratios, proportions, and unit conversions to scale recipes (CCSS 6.RP and 7.RP).
• Science: Measure and compare viscosity and density; relate concentration to physical properties (NGSS MS-PS1-1, HS-PS1-2).
• Engineering/Design: Create a scaled-up plan and simple cost model for production.
• ELA: Communicate findings and create a product pitch or lab report.

Estimated time

Three 45–60 minute lessons plus one extension day for presentations or scaled-up math.

Materials (classroom-friendly)

• Granulated sugar, water, citrus juice or tea for flavoring
• Stovetop or hot plate and stainless steel pots (adult supervision required)
• Kitchen scale (grams), graduated cylinders or measuring cups (mL), clear plastic cups
• Funnels or plastic tubing, stopwatches (phone timers), rulers
• Thermometers (food-safe), pH strips (optional), small jars for samples
• Printable worksheets: data table, viscosity flow chart, recipe-scaling template
• Safety supplies: oven mitts, goggles, first aid kit

Lesson 1 — Recipes, ratios, and concentration (Math-heavy)

Start with two classic syrup recipes to build intuition about ratios and concentration:

• Simple syrup (1:1 by mass): 100 g sugar + 100 g water
• Rich syrup (2:1 by mass): 200 g sugar + 100 g water

Class activity

1. Students weigh sugar and water to make both syrups in small batches (250 mL yield is good for group work).
2. Discuss why we use mass for sugar (more accurate) and volume for water; introduce density concept: density = mass / volume.
3. Have students calculate percent sugar by mass: % sugar = (mass sugar / total mass) × 100. Example: 200 g sugar + 100 g water = 300 g total → 200/300 = 66.7% sugar.
4. Short reflection: how would % sugar change if we doubled or halved the recipe? (Lead into proportional scaling.)

Standards alignment

Lesson 2 — Measuring density and viscosity (Science lab)

Students measure and compare physical properties of the two syrups they created.

Measuring density (simple, accurate)

1. Cool samples to room temperature.
2. Measure 100 mL of syrup in a graduated cylinder and record its mass. Example: if 100 mL syrup mass = 130 g, density = 130 g / 100 mL = 1.30 g/mL.
3. Compare densities of 1:1 and 2:1 syrups and relate differences to sugar concentration.

Measuring viscosity (classroom viscometer)

Professional viscometers are expensive. Use a simple flow-tube test or a funnel-drain test:

1. Set up a funnel over a graduated cylinder. Pour a fixed volume (e.g., 50 mL) of syrup into the funnel and start a timer when syrup begins to flow.
2. Record time to drain to a fixed mark (e.g., 10 mL left), or time to empty. Longer times = higher viscosity.
3. Repeat three times for each syrup and compute average.

Discuss sources of error: temperature (warmer syrup flows faster), funnel geometry, and human reaction time. This is an excellent opportunity to introduce controlled variables and repeated trials.

Data analysis and chemistry explanation

Students plot concentration vs. density and concentration vs. flow time. Use linear or nonlinear fits depending on grade level.

Explain: as sugar concentration increases there are more solute molecules interfering with water flow, increasing intermolecular friction and raising viscosity. Sugar also raises density because solute adds mass without proportional volume increase. Mention that additives like xanthan gum or pectin change viscosity differently (polymeric thickening vs. simple concentration).

Lesson 3 — Scaling up: from classroom jar to 1,500-gallon tank

Now connect math to a real-world story. Share the Liber & Co. example: what began in a single pot grew to commercial production in 1,500-gallon tanks and global customers. Use this as a launchpad for proportional reasoning and cost modeling.

Scaling math — step-by-step

1. Start with a classroom recipe yield. Example: 500 mL batch with 2:1 sugar recipe = 333 g sugar + 167 g water → 500 mL yield.
2. Convert target volume: 1,500 gallons × 3.78541 = 5,678.115 liters (5,678,115 mL).
3. Scaling factor = target volume / classroom yield in mL = 5,678,115 / 500 = 11,356.23.
4. Multiply each ingredient mass by scaling factor. Sugar required = 333 g × 11,356.23 ≈ 3,783, and so on (show rounding and significant figures lessons).

Practical constraints and chemistry considerations

Scaling isn't just multiply-and-go. Discuss:

• Heat transfer: large tanks need setup to maintain temperature and avoid scorching sugar.
• Mixing: full tanks require agitation to prevent stratification; lab stirrers won't suffice.
• Preservation and shelf life: concentration, pH, and sterile packaging affect stability.
• Supply chain: ingredient sourcing, bulk pricing, and waste management (sustainability trends are especially important in 2026).

Extension: simple production cost model and business pitch

Students apply math, economics, and communication skills to design a micro-business plan for scaled syrup production.

1. Calculate ingredient cost per ml using local prices (or supplied class prices).
2. Add utility costs (heat energy estimate), packaging, and labor (student-estimated) to compute per-unit cost.
3. Create a pricing strategy and break-even analysis. Encourage sustainability choices (e.g., reusable glass bottles) and local sourcing—linked to 2026 trends toward greener supply chains.
4. Present a 3-minute pitch to the class or local café partner.

Classroom management and safety tips

Working with hot sugar is the primary safety concern. Follow these rules:

• Adult supervision for heating and boiling steps.
• Use heat-safe gloves and goggles when handling pots and jars.
• Keep cold water and a first-aid kit on hand for burns.
• Label samples clearly to avoid ingestion; if tasting is part of the sensory assessment, have allergy consent and small sanitized spoons.
• Plan for cleanup—sugar sticks to surfaces; pre-soak pans and use warm soapy water.

Differentiation for grade bands

Upper elementary (grades 3–5)

• Simplify ratios (1:1 and 2:1) and use hands-on measuring by volume.
• Focus on observation, basic graphing, and vocabulary (viscosity, density).

Middle school (grades 6–8)

• Introduce percent concentration, simple density calculations, and experimental controls.
• Use CCSS 6.RP problems and NGSS practices to design experiments.

High school (grades 9–12)

• Model viscosity vs. concentration quantitatively; discuss non-Newtonian additives and polymer thickeners.
• Perform cost modeling, scaling with significant figures, and discuss process engineering considerations.

Real-world connections and current trends (2026)

By 2026, educators and industry partners increasingly support micro-manufacturing learning pathways. Key trends to highlight in class:

• Hands-on food science labs are being integrated into career-connected learning and hospitality tech pathways.
• Sustainability and circular packaging are curriculum drivers—students can test reusable bottle workflows.
• Local makers and boutique brands (like Liber & Co.) often partner with schools for internships and product testing; these partnerships grew after 2023–2025 maker-education investments.
• Data literacy and reproducible methods are prioritized—students publish findings in class repositories or local maker fairs.

Sample classroom data and worked math example

Example: 2:1 recipe (200 g sugar + 100 g water) yields 300 g ~ 300 mL. Measured density of 100 mL sample = 1.30 g/mL.

Scaling to 1500 gallons (5,678,115 mL):

1. Scaling factor = 5,678,115 / 300 ≈ 18,927.05
2. Sugar needed = 200 g × 18,927.05 ≈ 3,785,411 g ≈ 3,785.4 kg
3. Water needed = 100 g × 18,927.05 ≈ 1,892,705 g ≈ 1,892.7 L

Students learn that at industrial scale, quantities, cost, and logistics change the feasibility of recipe and process design.

Assessment idea: lab report + pitch

The summative assessment blends science and entrepreneurship:

• Lab report: hypothesis, methods, data (density and viscosity tables), error analysis
• Business brief: scaled materials list, cost per liter, sustainability notes
• Two-minute pitch to a mock buyer (local café owner or school admin)

Teacher hacks for low-budget classrooms

• Borrow kitchen scales and hot plates from home economics or community centers.
• Ask local cafés for small ingredient donations—many small brands support classroom partnerships.
• Use one demo heating station while groups perform measurements with pre-made samples.
• Turn the cost-model into a cross-curricular project with math or social studies to share the load.

Common questions and troubleshooting

Q: My syrup crystallized—what happened?

Crystallization is common when sugar concentration and cooling conditions favor crystal formation. Encourage stirring while cooling and consider using an acid (like a small amount of lemon juice) or invert sugar techniques at higher grades to discuss sucrose breakdown.

Q: How do we make viscosity measurements more reproducible?

Control temperature strictly, use identical funnels and volumes, and run multiple trials. If available, a low-cost rotational viscometer or a smartphone app with calibrated height-time tracking can improve precision.
