Grade Level: 9-12
Acid base titration, pH
Students explore pH and pH indicators with at-home materials. In this activity, students learn how titration is used in the production of biodiesel fuel and are challenged to conduct their own titration to determine the concentration of acetic acid in vinegar.
Grade Level: 6-8
Moon phases, seasons
Students explore their own questions after viewing two images of the sun from Chile in February 2017 and Idaho in August 2017. The investigation allows students to use sun-Earth-moon models to explain moon phases, solar eclipses, and eclipse seasons.
Grade Level: 9-12
Enzymes, subtrates
Students explore their own questions after reading a case study about a patient. The investigation allows students to understand the mechanism of lactose intolerance.
Grade Level: 6-8
Wavelength, amplitude
Students use models to learn about the properties of waves like amplitude, frequency, and wavelength. Students can then put their knowledge to the test as they try to assemble their own speaker at home.
Grade Level: 9-12
PCR, DNA sequence, species identification
Students will investigate shark fin DNA to determine if the fins come from an endangered species. Students will analyze PCR results via gel electrophoresis to make their conclusions.
