Hands-On Water Pressure Science Experiments (Scientific Method Lab Journal)

🔬 Hands-On Water Pressure Science Experiments (Scientific Method Lab Journal)

Bring science to life with this engaging, hands-on water pressure experiment set designed to help students practice the scientific method through real-world investigation and observation!

Students will explore how air pressure, water pressure, and surface tension work together through 3 exciting, easy-to-set-up experiments using simple household materials.

🧪 Step-by-Step Experiments Included

💧 Experiment 1: The Upside-Down Water Glass Challenge

Students investigate what happens when a water-filled glass is inverted underwater and slowly lifted.

They make predictions, test their hypothesis, and observe how water behaves under pressure.

🧻 Experiment 2: The “Dry Tissue” Air Pressure Test

Students place a tissue inside an inverted glass and push it into water.

They discover how trapped air creates a barrier that keeps the tissue completely dry.

📄 Experiment 3: The Card “Water Seal” Challenge

Students use cardstock to cover a partially filled glass of water, flip it upside down, and release their hand.

They observe how air pressure holds the card in place and keeps water from spilling out.
