How do scientists know when our planet is changing? It starts with observation, measurement, and data. As COP31 and Earth Information Day put global climate observations in the spotlight, this week’s Monday Blog explores how teachers can bring the same scientific process into the classroom through weather measurements, long-term data collection, and evidence-based investigation.

By mid-semester, science teachers know which equipment gets used, which supplies are running low, and where shortages are making investigations harder than they should be. This week’s Monday Blog offers a practical science lab checkup to help teachers and department leaders identify equipment gaps, improve classroom readiness, and make smarter purchasing decisions before the second half of the year.
