Chemical Element Interview
Students interview the chemical elements. They research information about their element, such as: stable isotopes, valence electrons, number of subatomic particles. They create a yearbook page for their element, and a format to present it.
Curated OER
Sink or Swim
Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

How Do Scientists Research For Lab Activities?
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.
Curated OER
Individual Gas Laws
Students 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.
Curated OER
Separating a Starch-Glucose Mixture Using Gel Filtration
Students 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.
Curated OER
Set the Stage
Students 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...
Curated OER
Chemical Changes
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...
Curated OER
Lithography Techniques/Making a Printed Circuit Board
Students create an electronic schematic on their PCB. In this physics instructional activity, students solder and assemble electronic components. They research the function of these components and share their findings in a group.
Curated OER
Water Quality
Learners 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.
Curated OER
Water: Friend and Foe
Students brainstorm ways to prevent fires from home. In this technology lesson, students create fire-safety posters for their school. They research the internet and explore other resources to get information for the poster.
Curated OER
Diaper Challenge
Students investigate the absorbency of certain diapers. For this inquiry lesson, students examine how much water the crystals absorb. They collect data and share their results in class.
Curated OER
Studying with Chemical Compounds
Students create a foldable to help them remember topics on chemical compounds. In this physical science lesson, students differentiate ionic and covalent compounds. Given certain compounds, they identify whether it's ionic or covalent.
Curated OER
Baking Soda and Vinegar Volcano
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.
Curated OER
Global Change — Change and Cycles Where Land, Air and Water Meet
Students participate in an experiment to define a parts-per-billion solution. In this ecology instructional activity, students select a second substance to create a parts-per-billion solution and observe and record their results....
Curated OER
Acids and Bases
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.
Curated OER
The Energy Debate - Energy of Peanut
Students 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.
Curated OER
Which Brand of Air Freshener is Most Cost Effective?
Students use scientific method to determine cost-effectiveness of air freshener, and create PowerPoint presentations to share their results.
