Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Students explore how principles of gas behavior relate to diving in order to plan safe underwater activities.

Students investigate and explain the differences active transport versus passive transport. This lesson includes an individual and group activity. The basic steps of electrophores is the focus of inquiry. Identification of the pure...

Students explore the nature of scientific knowledge. They will also explore how to develop a lab plan to explain the structures of molecules and atoms. Research is essential to the success of the lab using necessary educational software.

Young scholars learn the relationships between the different properties of a gas and use previous knowledge and make predictions. They predit and explain certain phenomena of gases using their chemical knowledge.

Young scholars experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.

Learners observe evaporation in a controlled environment. Evaporation is the change of liquid water into water vapor (a gas). The rate of evaporation is determined by many factors such as air temperature and humidity, liquid temperature...

Students explore chemical changes. in this lesson about the properties of chemical changes, students do experiments, observe, and record results. Students complete four experiments in order to observe chemical changes. In each experiment...

Learners create an electronic schematic on their PCB. In this physics lesson, students solder and assemble electronic components. They research the function of these components and share their findings in a group.

Students play the role of scientists testing for water quality in the area. In this ecology lesson, students determine the water sample's pH, temperature, dissolved oxygen and turbidity. They write a journal reflection after the activity.

Students brainstorm ways to prevent fires from home. In this technology activity, students create fire-safety posters for their school. They research the internet and explore other resources to get information for the poster.

Students investigate the absorbency of certain diapers. In this inquiry lesson, students examine how much water the crystals absorb. They collect data and share their results in class.

Young scholars create a foldable to help them remember topics on chemical compounds. In this physical science activity, students differentiate ionic and covalent compounds. Given certain compounds, they identify whether it's ionic or...

Students construct a volcano using baking soda and vinegar. In this earth science lesson, students explain the reaction that takes place when these two chemicals combine together.

Students participate in an experiment to define a parts-per-billion solution. In this ecology lesson, students select a second substance to create a parts-per-billion solution and observe and record their results. Students work in groups...

Students use supporting evidence to predict if common household substances are acids or bases. They determine the pH of the substances and describe the results of the investigation and characteristics of each substance.

Young scholars articulate the difference between the terms heat and temperature. They calculate the amount of energy associated with a given temperature rise and design an experiment to measure the energy of a fuel.

Students use scientific method to determine cost-effectiveness of air freshener, and create PowerPoint presentations to share their results.

Students identify principles behind acid-base reactions. They predict factors that may affect an acid-base reaction. Students identify questions and concepts that guide scientific investigations.

Students describe an isotope and radioactive isotope in a written essay. They describe how a specific country or region was affected by radioactive contamination and attempt to sympathize with those affected by these radioactive...

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

Students describe what global warming is, what causes global warming and the impact to our world. They study the threat of global warming and its relationship to the use of fossil fuels.

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.

Students research and study the disaster of Bhopal to grasp the essential concept of controlling chemical reactions. They explain how the Bhopal disaster might have been prevented based upon their knowledge of factors affecting the rate...
