Properties Of Water Lab Answers

Investigation: Properties of Water with Lab Stations

In AP Biology, early on units focus on the chemistry of life which includes the topic of water backdrop. Water backdrop that are essential to life include cohesion and adhesion, water's polarity, water as a solvent, and its high heat capacity. I usually provide students with a short introductory lecture before students caput to the lab.

In this action, students movement through stations where they perform tasks that demonstrate these water properties. They answer questions as they go on the student handout and bear a last inquiry activeness on factors that affect evaporation.

The educatee handout includes instructions for each station. Yous could likewise print cards for stations that have instructions on them and requite students a more than streamlined handout to write their answers.

Well-nigh of the materials required are uncomplicated and bachelor in about science labs. This document outlines all the materials needed and includes photos of the lab stations for simple reference.

Quick Overview of Stations:

Surface tension using pennies, soap, and h2o
Surface tension using whole milk, water and food coloring (creating swirls)
Density vs surface tension using aluminum foil
Create a mini lava lamp using nutrient coloring, Alka seltzer tablets, h2o and oil.
Warm water versus cold water (submerged exam tubes)
Solubility of carbohydrate and common salt in h2o and in ethanol
