Students research types of chromatography and complete chromatography experiments.

Students observe seeds growth and examine the different parts of the seedling. In this biology lesson, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...

Students explore vermicomposting, the species of worms needed and the proper climate for it.  In this composting lesson students make their own worm compost bin. 

Students explore what factors affect population dynamics, identify factors affecting fish populations, and use Stella to model how dissolved oxygen affects fish populations.

Students explore energy. In this science lesson, students conduct an experiment in which they measure how much energy is produced by the sun. Students build a calorimeter to measure the amount of energy.

Students examine the different changes in matter.  In this chemical change lesson students determine the amount of reactant made in a reaction using the law of conservation. 

Students differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Students experiment with a household example of an emulsion polymer.

In this photosynthesis activity, students follow the steps to complete a science investigation and then respond to 8 short answer questions regarding the photosynthesis investigation.

Students examine antigens including ones found in humans.  In this immune instructional activity students complete several experiments in relation to antigens and antibodies.

High schoolers view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.

Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...

Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...

Lab activity where young scholars determine the relationship of pressure and temperature on gas solubility.

A lab activity where students will identify an unknown crystal by applying a dissolving test.

Learn about the effect of temperature on the solubility of gases in this lab activity. This lab activity includes instructions for both student and teacher.

A collection of over 30 virtual chemistry problems with accompanying interactive activities. Each problem includes a word file for potential differentiation in your classroom.

To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink. They use...

Determine the concentration of an unknown NaCl solution using the common ion effect.

Pupils can figure out what an unknown crystal is by comparing their dissolving test with the known and unknown crystals. This inquiry activity includes background information and student handout.

This activity provides a demonstration of Hess's Law using three reactions: the solubility NaOH in water, the solubility NaOH in HCl, and the reaction of a solution of HCl and a solution of NaOH.

A lab activity that introduces chromatography using markers, plus water and acetone as the solvents. Pupils will take measurements to compare the mobile and stationary phases of the inks, and find the polarity of the inks and solvents....

Use silver chloride to determine the binding constant for a metal ligand complex.

In this chemistry lab, students investigate how oil and water don't mix. They will work on their observation skills and their ability to follow directions to ensure they get the correct results. Students can then develop a new, testable...

Media-rich lesson in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...
