Sound Pollution Assessment Lab
Sound pollution, or noise pollution, is unwanted or harmful sound that disrupts the environment. The decibel (dB) scale measures sound intensity logarithmically, meaning each 10 dB increase represents a tenfold increase in sound intensity. Prolonged exposure to sounds above 85 dB can cause hearing damage, while levels above 120 dB can cause immediate harm. Smartphone apps use the device's microphone to estimate sound levels, but their accuracy can vary based on microphone quality, calibration, a

AP Environmental Science | LD₅₀ Dice Lab: Modeling Lethal Dose and Toxicity
🎲 LD₅₀ Dice Lab: Modeling Lethal Dose and Toxicity Bring data analysis and toxicology to life with this engaging LD₅₀ Dice Lab! In this hands-on simulation, students model how scientists determine the lethal dose (LD₅₀) of a substance, the dose that kills 50% of a test population. Using dice to represent random variation in organism sensitivity, students explore how chance and biological diversity affect the outcomes of toxicity studies. 🧪 OverviewWhen scientists study toxins, they expose

IB DP Environmental Systems & Societies Lab - Soil properties
Lab activity for ESS topic 5.1
Students are introduced to 3 different methods to classify soils and determine their moisture and organic (carbon) content.
Soil classification uses the gravimetric method of placing soil samples in glass gas flasks or graduated cylinders with water, shaking it well and letting the particles fall out of suspension and determine boundaries between sand, silt and clay. These then are plotted on tri-linear soil classification diagrams.
Soil and organic (carbon) conten

Gardening Project Middle school | Water Conservation Project
Give students real ownership of the scientific process with this Inquiry Learning Experiment Design Project Prompt. Instead of following a step-by-step lab, students design their own experiment using classroom materials you already have. With structured thinking prompts (but plenty of creative freedom), students plan an investigation that demonstrates the skills they’ve been learning, then write and reflect on what happened, even if their results are messy or their experiment “fails.” This re
