Students measure the mass, volume, length and area of various objects. They are assigned a letter. The task is assesses students' abilities to make simple observations and measurements.

A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

Students determine the characteristics of a stream ecosystem and its organisms.  For this water ecology lesson students complete several labs that shows them presence of life, water appearance, and water flow.

In this solubility product constant of sodium chloride worksheet, students gather the equipment needed and follow the procedures to determine the solubility product constant of a solute and demonstrate precipitation of a common ion to a...

Students calculate the SA/V ratio and volume of phenophthalien agar that are cut into different shapes. They then let ammonia diffuse into the various pieces of agar and determine the effect that SA/V had on the rate of diffusion.

Students determine the density of different substances. In this physical science lesson plan, students rank them according to their density. They discover the relationship between volume and density.

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Can a sponge cure cancer? Life science pupils visit the drugstore under the sea in the fifth lesson of six. Working groups research the topic then get hands-on experience by testing the inhibiting effects of several plant extracts...

In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Estimating Errors in Chemistry is a detailed handout that illustrates the importance of calculating the percent error when working in the chemistry lab. There are no actual problems to solve, just notes and examples of calculations. Hand...

Explore the chemical components of water through an electrolysis reaction. Scholars use a battery to divide various water solutions into different gases. As they collect the gases, they measure the volume and make a comparison to the...
