Problem Set 4

Though there are technically only 13 questions on this exam, they take up six pages and make a thorough assessment of organic chemistry principles. There are plenty of diagrams to label or complete. Emission spectra are displayed for...

Young biochemists examine the reactions that make life possible with this set of practice problems. Focusing specifically on carbohydrate compounds, these multi-step questions challenge students to demonstrate their understanding of the...

In this chemistry worksheet, students work on a problem set consisting of 16 equations in which they synthesize carboxylic acid derivatives.

All units and significant figures should be used correctly as part of this check on molar mass calculations.  These word problems range in complexity and present the missing variable in different ways. Your young scientists might enjoy...

What features make a home energy-efficient? Pupils attempt to answer the question with the fourth lesson from the five-part WE Are Innovators—High School Modules set. Scholars learn how certain building materials help save energy. Using...

Three pedigrees are presented for junior geneticists to interpret. Then, a double strand of DNA is printed for them to analyze. Hypothetical animal crosses are described, from which learners determine the genotypes and phenotypes of the...

In this organic chemistry of alkynes worksheet, students write products for reactions in 9 equation problems. They show the synthesis steps for 3 reactions and write the names for 3 compounds.

The reaction of Phosphorus and Chlorine is the focus of this video on Stoichiometry. Sal sets up a reaction between the two substances, and uses the process of Stoichiometry in order to calculate how many grams of Phosphorus Trichloride...

Sal continues his explanation of The Ideal Gas Equation in this chemistry video. He sets up a different problem from the previous video, and uses the ideal gas equation to calculate the molar mass of a 98 ml container that contains .081...

Young scholars explore reasons for setting goals and techniques to achieve them. They discover the importance of setting goals, both short-range and long-range. Students assess their own situation and write specific goals to meet...
