Students develop a comprehension of parts per million as a concept. They work in teams to create successive dilutions of a solution to reach a parts-per-million concentration. Students list what they think the atmosphere is made of. They...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

Students develop a method to separate different types of mixtures. In this chemistry lesson, students model the steps in the scientific method. They perform the experiment and analyze data.

Experienced chemistry technicians use then layer chromatography to discover how much of a free compound is left after each rinse cycle. Where this could obviously be used as a practice with chromatography technique, it can also be used...

In search of an organic lab that employs real-life techniques and analysis methods? Groups carry out the nitration of methyl benzoate, then attempt to determine the number and location of the nitro groups added to the benzene ring....

Through a hands-on activity, an acetone-spinach solution is pre-made and learners use this solution to separate the pigments found in spinach using chromatography. The comprehensive resource includes an analysis and conclusion...

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

Students mix solutions of polyvinyl alcohol and borax. They predict what happen and record their observations. They prepare a T-chart comparing Jell-o to their mixture.

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...

In this mixtures pre-lab worksheet, students compare and contrast suspensions and colloids and solutions and colloids. Students describe the Tyndall effect. This worksheet has 10 short answer questions.

Dracula isn't the only one who needs blood to survive. The eight-part unit includes seven lessons, five demonstrations, seven labs, and a project to organize a blood drive. Class members learn about the parts of...

Students test for the presence of enzymes in fruit and the specificity of those enzymes, as well as to identify and show the susceptibility of enzymes to certain environmental factors (temperature and pH) originating in the enzyme's...

Students are introduced to the principles of gel electrophoresis. They practice loading gels and pipetting. For this laboratory activity, food color is separated into constituent pigments. The lab can be run with standard...

Middle schoolers experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry lesson. The lesson was written for an advanced 6th grade class.

High schoolers use short-chain polymers and borate ions to produce cross-linked polymers in the lab. In this cross-linked polymer lesson plan, students produce polyvinyl acetate slime and polyvinyl alcohol slime and test their physical...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

In this polymer worksheet, learners make two types of cross linked polymers and they test their physical properties. These include their response to agitation, stretchability, viscosity, and resilience.

For this solutions worksheet, students review how molarity is calculated and how to prepare a dilute solution. This worksheet has 5 problems to solve.

Students work in teams to use the scientific method to separate complex mixtures into pure components.

Scratch and sniff an introduction to organic chemical reactions. A creative lesson has individuals study the esters commonly used in scratch-and-sniff stickers and advertisements. Following the lab procedure, scholars create the organic...

Students test for the presence of enzymes in fruit and the specificity of those enzymes. They identify the susceptibility of enzymes to certain environmental factors such as temperature and pH in the enzymes environment.

Young scholars investigate the coefficients in a chemical equation and their relation to moles. In this moles and coefficients lesson plan, students perform a single replacement reaction of copper (II) sulfate and zinc and find the ratio...

Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.
