Students prepare a sample of a commercial hand lotion for analysis by HPLC to determine the percent composition of two common cosmetic preservatives, methylparaben and propylparaben. They perform the analysis and the data is evaluated to...

Explore patterns, variables, and mathematical relationships when you examine patterns with toothpicks and determine the next sequence of figures. Your class writes and justifies a formula based on the sequence. An answer key is included.

When life gives you mold, make penicillin. Scholars design an inquiry experiment to determine what causes rotting and mold growth. It also covers decomposers and the important role they play for other living things. 

Scientists need to have mastered algebraic slope-intercept concepts in order for this lesson to be effective. They will measure and graph solar panel output as a function of the amount of radiation striking it, discovering that there is...

A math and science worksheet prompts learners to simulate how scientists determine populations of animals out in the wild. They use goldfish crackers, paper bags, and a styrofoam cup as their tools. An excellent cooperative group activity!

Students watch a video about climbers on Mount Everest. In groups, they complete experiments in which they determine the concentration of oxygen in the air. They make predictions before beginning the experiment and complete a worksheet...

Whether in the UK or the US, the mass of the copper in a copper alloy penny can be determined. If you are in the US, note that on the lab sheet, a penny is identified as a "1p piece." The penny is dissolved by young chemists in nitric...

Help learners discover methods to estimate animal population. They will participate in a simulation of catching and tagging fish in order to estimate the fish population. They scoop and count goldfish crackers, record data, and use...

A two-page instructional activity provides seven Punnett squares for practice in determining genotypes and phenotypes. Each is an example of incomplete dominance or codominance. After your bright biologists have mastered Punnett squares,...

Students determine patterns. In this mathematics lesson, students act out a skit, play a sequence game, and complete patterns. Students use problems solving skills.

Middle schoolers receive a handout that lists the five types of context clues. The class divides up into groups of three or four, and each group chooses five unfamiliar words. They write a multiple-choice question for each of their five...

In the third activity from this unit based on the book Bullfrog at Magnolia Circle, learners focus on using specific details from the text-to-answer questions about the habitat of bullfrogs. While reading the text, young...

The outcome of 90 percent of criminal cases in the US is determined by plea bargains. Clips from the documentary Better This World create the backdrop for an investigation of the benefits and drawbacks of the plea bargaining process....

Here's an algebra II activity that strives to make the concept of a radian less abstract and more conceptual. It takes a hands-on approach to exploring the idea of a radian and allows individuals to develop a definition of a...

Young chemists perform an experiment to determine if a compound is iron (II) chloride or iron (III) chloride. Then they determine the formula, balance the equation, and answer analysis questions. 

With many factors leading to a great athlete, does height make Usain Bolt unfairly fast? Middle schoolers conduct analysis to change the running distance of the Olympic races to be proportional to the height of the participants. They...

During an inquiry-based lesson plan, scholars decide which variable to test and then design an experiment to determine the needs of producers. After two weeks, they complete a full analysis and research paper.

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

Historians have proven that as early as 1497 skilled navigators were using a kamal to sail across oceans. Scholars learn about navigation tools and astronomy before building their own kamals. They then learn how to use it to determine...

Why do medical examiners always state the contents of a person's stomach? Scholars learn about the importance of macromolecules through a case study of stomach contents. They perform multiple tests to determine a conclusion before they...

Students identify someone they know who has overcome an obstacle in his/her life. They discuss difficult things they have done in their own lives and how one has to overcome obstacles to succeed.

Young scholars use the Live Access Server (LAS) to form maps and a numerical text file of snow cover for each continent on a particular date and analyze the data for each map, corresponding text file to determine an estimate of snow...

Here is a fine lesson plan on geology designed for high schoolers. Learners use rocks, fossils, and other geological clues to determine the geology of an area. Then, they make recommendations to a fictitious city council about the...
