Entry Events
Events that will be used to introduce the project to studentsThe Mystery Crate Arrival
A mysterious, ventilated crate arrives in the classroom labeled 'URGENT: WILDLIFE REHABILITATION.' Inside, students find a plush 'patient,' a scale, and a medical file with missing data, sparking an immediate need to calculate the animal's mass in kg and determine the correct mL dosage before the next feeding time.Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.The Patient Admissions Clinic
In this introductory activity, students take on the role of an Admissions Medic. They receive their 'patient' (a plush animal or image) and must conduct an initial intake assessment. Students will use scales to measure the mass of their animal in kilograms and grams, and use graduated cylinders or measuring beakers to estimate and measure the volume of a 'hydration fluid' (water) the animal needs based on its size.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA 'Patient Intake Form' featuring the animal's name, species, recorded mass in kg/g, and initial hydration volume in mL.Alignment
How this activity aligns with the learning objectives & standardsAligns with CCSS.MATH.CONTENT.3.MD.A.2 (Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg)). It also addresses the goal of explaining thinking using models and words.The Pharmacy Lab: Dosage Calculations
Now that the patients are admitted, students must calculate the correct dosage of 'liquid vitamins' or 'medicine' (colored water). Students are given a dosage chart (e.g., 5mL of medicine for every 1kg of animal mass). They must use multiplication or repeated addition to calculate the total dosage for their specific animal. This activity bridges the gap between simple measurement and operational math.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA 'Dosage Calculation Worksheet' showing the equations used to determine the total mL of medicine required, along with a labeled 'Medicine Cup' (physical or drawn) showing the exact fill line.Alignment

Wildlife recovery depends on strict schedules. In this activity, students create a 'Round-the-Clock' care plan. They are given a starting time for the first feeding and must calculate the times for subsequent treatments throughout the day based on intervals (e.g., every 45 minutes or every 2 hours and 15 minutes). This introduces elapsed time in a high-stakes, realistic context.Steps
Here is some basic scaffolding to help students complete the activity.Final Product
What students will submit as the final product of the activityA '24-Hour Treatment Clock' or timeline that displays the exact time (to the minute) for every feeding and medication dose for their patient.Alignment
How this activity aligns with the learning objectives & standardsAligns with CCSS.MATH.CONTENT.3.MD.A.1 (Tell and write time to the nearest minute and measure time intervals in minutes; solve word problems involving elapsed time).The Recovery Ruler: Fractional Growth
As the animals recover, their growth must be monitored. Students are given 'weekly photos' or models of their animal's tail, wing, or body length. They must use a ruler to measure these parts to the nearest 1/2 and 1/4 inch. They will then place these measurements on a 'Growth Number Line' to visualize how the animal is getting longer/stronger over time, specifically identifying fractions greater than 1.Steps

In this final activity, students combine their data with their 'fellow medics' (classmates). They will collect the 'Final Growth' measurements of all animals in the rescue center. Students will organize this data into a line plot. They will then use the line plot to answer questions about the rescue center's success, such as 'What was the most common length of a recovered animal?' or 'How many animals grew more than 3 1/2 inches?'Steps
