Question

step 1: pick your properties
choose two properties of water you want to test.
property 1: cohesion (water sticks to itself)
property 2: adhesion (water sticks to other things)

step 2: real - life connection
for each property, describe a real life situation where it matters.
property 1 connection: cohesion lets bugs like water striders walk on water.
property 2 connection: adhesion helps water climb up a paper towel or move up the stem of a plant.

step 3: question
turn each property into a testable question
question 1:

question 2:

step 4: materials
list only items you could realistically find in a classroom, school lab, or home.

Explanation:

For the property of cohesion, a testable question could be about the maximum weight that can be supported by the cohesive force of water's surface tension. For adhesion, a testable question could be related to how different materials affect the rate at which water climbs due to adhesion. Common materials for testing these could include water, small insects or objects to test cohesion on water surface, paper towels, glass tubes for capillary - action (adhesion) experiments.

Answer:

Question 1: How much weight can the cohesive force of water's surface support?
Question 2: How does the type of material affect the rate of water climbing due to adhesion?
Materials: Water, small insects or light objects, paper towels, glass tubes.
