Our Universe: Designed or Evolved?
Students brainstorm and write arguments for Evolution and Intelligent Design. They research the history of each of these ideas. They also examine the controversy of teaching one or both ideas in schools.
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
Radioactivity Experiments
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...
Curated OER
Physical and Chemical Changes
In this changes worksheet, students observe and record changes that occur in their every day life and classify these changes as either physical or chemical change. Students record their information in a graphic organizer.
Curated OER
Crystal Growing
Students explore the different phases of a crystal. In this mineral lesson plan students grow their own sugar crystals using a sugar recipe.
Curated OER
Dust in the Wind; Chemicals in the Water
Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...
Curated OER
Polymerization Experiments
Students study the concepts of polymerization and the function of crosslinkage. In this polymer lesson plan students complete a lab activity and write down their observations.
