Vernier - Microscale Acid-Base Titration
In this activity, students' will use a pH sensor to determine the change in pH during a titration of a known concentration of NaOH and unknown concentration of HCl. Students' will determine the concentration of unknown HCl.https://education.ti.com/en/activity/detail/vernier--microscale-acidbase-titration
Vernier - Nitrate
Student uses the Nitrate Ion-Selective Probe to measure the Nitrate ions concentration in water samples. In another method, student converts nitrate ions to nitrite and use the Vernier Colorimeter to measure nitrite and calculate the nitrate levels.https://education.ti.com/en/activity/detail/vernier--nitrate
Vernier - Determining the Mole Ratios in a Chemical Reaction
Measure the enthalpy change of a series of reactions. Determine the stoichiometry of an oxidation-reduction reaction in which the reactants are known but the products are unknown.https://education.ti.com/en/activity/detail/vernier--determining-the-mole-ratios-in-a-chemical-reaction
Call it ...Dominant or Recessive
In this activity, students simulate a Punnett square of a cross between two heterozygous individuals and produce a histogram. They compare actual and expected results of genetic crosses.https://education.ti.com/en/activity/detail/call-it----dominant-or-recessive
Diprotic Acid Lab and Easy Data
Maleic Acid gives an excellent diprotic acid titration curve showing both inflection points clearly for calculation of molecular weight.https://education.ti.com/en/activity/detail/diprotic-acid-lab-and-easy-data
Growing Babies
In this activity, students observe and graph data about human fetal growth rates. Students build a regression model based on the data and compare values with those of other mammals. They also compare the data to non-mammal species.https://education.ti.com/en/activity/detail/growing-babies
