Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

High schoolers determine the molar mass of a gas. In this molar mass of a gas lesson plan, students use the vapor density of an organic solvent to determine its molar mass. They vaporize the solvent and collect the vapor. Once it is...

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

No chemistry lab? No problem! Scholars use a virtual lab to determine the solubility product of four different chemicals. They then use the results of their experiments to see if higher solubility product values equal greater solubility.

Here's a solid resource for solubility. Given the solubility of copper chloride at two different temperatures, young chemists need to determine the solubility at a third given temperature. Using a virtual lab, they design and conduct an...

A TI-nspire instructional activity to find determinants of matrices using calculators. The class follows along in this step by step activity to explore operations on matrices. They will mostly be multiplying and at the end of the...

Humans, fruit flies, and reptiles have their own rules where sex chromosomes are concerned. Scholars flip through a slide show offering an explanation of the chromosomes that determine the sex of different species. What is female in one...

In this determinants learning exercise, students solve and complete 12 different types of problems. First, they evaluate the determinant in each matrix illustrated. Then, students determine the value of x that makes the determinant given.

In this matrices learning exercise, students find the value of 14 2x2 matrices. They evaluate one addition of matrices problem. Students give an example of a 2x2 matrix with a given determinant.

Students investigate the rate determining step in a chemical reaction and how catalysts effect reactions. In this rate determining step and catalyst lesson, students work in groups to perform 5 tasks. They rotate each task and time how...

In the first of a two-day lesson on transformations with matrix notation the class transforms the unit square using general transformations, then calculates the area of the transformed image. They discover it is the same as finding...

Students determine the concentration of chloride ions in seawater. In this determination of chloride ions lesson plan, students perform a titration of sea water with silver nitrate and an indicator to determine the chloride ion...

Learners consider a set of questions to determine a series of transformations that will move one figure to another. Once the series is determined, the pupil then determines whether the pre-image and image are either congruent...

After re-reading The Omnivore’s Dilemma using a Reading Closely: Guiding Questions handout, class members use sticky notes to annotate and determine the gist of the text. Finally, they use an Author’s Purpose graphic organizer to...

Does the crystal structure of a hydrated solid determine the proportion of water absorbed, or does the application of heat change the absorption? Scholars experiment with both variables to determine the answer. They add their collected...

Francis Raoult discovered the change in boiling points of solutions varies by the number of particles in the solution. Scholars apply the concept to determine the molality of a solution based on the change in boiling point. They use an...

Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...

Many young scientists don't realize iron exists in two different forms in nature. During an enlightening experiment, they react iron with copper sulfate to cause a single replacement reaction. Then, they determine the correct...

Many periodic tables mention specific heat, but how do scientists determine those numbers? Scholars attempt to find the specific heat of a metallic element by using a calorimeter. Three experimental trials ensure accuracy, and analysis...

Each slide contains a group of animals and an equation that adds up to 10. However each equation is missing a number, learners attempt to determine the missing addend to revile the number of animals hiding under the cloud. A fun,...

Can any three side lengths create a triangle? Your classes tackle this question and more in the 11th lesson of the 29-part module. Through modeling with patty paper, individuals discover the relationship between the lengths of the sides...

Young mathematicians to the rescue! Pupils use an interactive to find lengths relating a ladder against a building. The problems involve determining how long a ladder must be to reach a given floor to what floor can a given ladder reach.

Pupils use an interactive to help visualize the right triangles needed to calculate distances between friends' houses. Individuals solve five problems on how to determine distances and comparing the distances.

Let the function drive the activity. The interactive displays the odometer on a car for a trip. Pupils determine and interpret the slope of the situation. Then, they find a verbal description of the equation of the function.
