A share-a-thon is a place where teachers can voluntarily upload their files for other teachers to use. When a teacher submits a file, it is catalogued and placed into a database. To view more materials from the topic above or from different branches of science click here.
Measurement Lab
Purpose: demonstrate accuracy and precision in data collection and analysis
Evidence Of Chemical Change
In this small scale lab students observe
several different reactions in a test
tube. Initial focus is identifying
observations that indicate a chemical
change occurred; also nomenclature,
writing balanced chemical equations,
identifying type
Seperating Mixtures
To separate a mixture using paper
chromatography
Junk Food Labs
This is a simple lab to demonstrate density columns; the cool thing is the students can drink their own project. Takes about half a period. I use special lab glassware that is used for EATING only, stored in a separate closet so no glassware may become
Accuracy And Precision
A lab script designed to allow students to determine the accuracy and precision of measurements using 3-4 different types of glassware used for volume measurement in a chemistry lab. I use this with my form 6 students (ages 16-18).
Titration
The titration of vinegar with NaOH using Pheonthalein as an indicator.
Densities Of Solutions
Students see how density affects
interaction of different solutions.
Radioactivity
Using a Toppler game, students discover
how atoms become unstable and decay.
Exothermic/Endothermic Reactions
Measure the changes in temperature in
reactions and then determine whether or
not the reaction is endo- or exothermic.
Polarity In Covalent Bonds
Construct a compound diagram that is
useful in describing polarity. Questions
follow the activity.
