What is in the Water?
For this mixtures worksheet, high schoolers read about mixture and what determines if a solute dissolves in a solvent. They answer three questions about solutions and determine from a list of compounds which are soluble in water.

Mixtures of Matter
Students experiment with mixtures of matter. In this matter instructional activity, students investigate which liquids form a solution when mixed together and which do not. Students also identify which solids can be separated from matter.
Curated OER
Mixtures of Matter
Students experiment with solids and liquids. In this mixtures of matter lesson, students combine matter to form solutions. Students hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by having...

Mixtures as Solutions or Colloids and the Tyndall Effect
Students classify mixtures as solution or colloids by virtue of the Tyndall Effect. They make a cone and tape to fit over the lens of the flashlight. They turn out the lights in the room and shine the flash light at each of the jars and...
Curated OER
Mixtures
Sixth graders experiment with mixtures. For this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

Vocab Science Chapter 1
In this word search worksheet, students locate 20 words related to science. The word list includes volume, mixture, and solute.
Curated OER
Solutions, Suspensions, & Colloids Lab
In this solutions, suspension and colloid worksheet, students complete a lab experiment in order to determine if a given mixture is a solution, suspension or colloid. They are given six vials and they record their observations of each...
Curated OER
My Type of Mixture
In this mixture worksheet, students fill two test tubes with water and add starch to one and salt to the other. They stir the solutions and observe their appearance. They answer four questions about their mixtures and determine if they...
Curated OER
The Effects of Temperature on Chemical Mixtures
Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.
Curated OER
Mixture Mayhem
In this mixture worksheet, students are given five mixtures and they determine if each is a mechanical mixture or a solution. They also identify the way each substance within the mixture can be separated from the others.
Curated OER
Mixtures Lab
Students classify different mixtures. For this mixtures lesson plan, students determine samples to be suspensions, colloids, or solutions and compare homogeneous and heterogeneous mixtures.
Curated OER
Elements Compounds and Mixtures
In this science worksheet, students apply science basic knowledge of chemistry to the puzzles that are listed for the four parts of the sheet while focusing upon the identification of a metalloid.

Unknown Powders
Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.
Concord Consortium
Protein Folding
Long strings of amino acids fold themselves into stable peptides. The simulation allows scholars to observe the process in multiple ways. Using hydrophobic, hydrophilic, or a combination of proteins in three different solutions, the...
Beyond Benign
Urine Jeopardy
Urine can tell us a lot about what is happening in our bodies. In a hands-on activity, scholars administer pH, glucose, ketone, and protein tests to a sample of "urine" solution made from household ingredients. Their results lead them to...
