Test your fifth graders' math skills with five word problems involving fractions. After studying two examples at the top of the page, pupils multiply fractions by whole numbers to solve each word problem. The worksheet provides two...

In this redox reaction laboratory sheet, chemists answer eight post-lab questions about oxidizing agents, reducing agents, oxidized and reduced substances, and percent yield of products. You will need to provide a proedure for...

Young scholars examine the history of Japanese farming and current international farming issues. They conduct Internet research, create a chart to illustrate the history of farm products in Japan, and simulate a WTO meeting.

Students evaluate snack foods based on calories and fat. In small groups, they use this information to make informed and wise food choices. Students graphically represent the fat in a food by measuring the equivalent of the food fat with...

The scientific issue of carbon-14 dating and exponential decay gets a statistics-based treatment in this problem. The class starts with a basic investigation of carbon content, but then branches out to questions of accuracy and...

Tenth graders investigate the carbon monoxide level at a fixed latitude. They determine if there is a relationship to population density. They download data sets and generate a graph. They determine a link between human activity and...

What are the factors that influence voting patterns? How do these factors influence government funding? Is participation the squeaky wheel gets the grease? Class members interpret graphs and analyze trends to determine what...

Don't let the term, "slotted wood board" detract you from the value of this experiment. Class members tie a string to a cart and, with even horizontal force, drag it up an inclined plane. The objective is to compare the work done with...

Explain the four categories of financial indicators (commodity prices, stock indexes, interest rates, and yield spreads), and help your class members understand how changes in this data can affect decisions regarding consumer spending,...

Middle schoolers take a close look at the prairie environment. They identify common plants and animals of the prairie. In addition, pupils work in teams in order to put together a presentation on a certain aspect of the prairie...

Here's a stat for your pupils: 18 percent of the human body is carbon! Part 10 in the series of 12 takes pairs on an adventure through the carbon cycle. After a class reading about carbon, pairs read and choose their own adventure...

Get a line on the snakes. The assessment task requires the class to determine the species of unknown snakes based upon collected data. Individuals analyze two scatter plots and determine the most likely species for five...

Find that slope! This video does an excellent job of demonstrating how to use the slope formula to find the slope of a line using two points. The instructor first reviews the definition of slope of a line, then works three problems using...

This short presentation provides a convenient introduction to the nitrogen group in the periodic table of elements. A graphic displays where they are placed in the periodic table. The nitrogen cycle is mentioned and ammonia is explained....

Students demonstrate effects of waste on environment and ways of reducing it, observe how much packaging goes into bag lunches each day, and survey their families to assess awareness levels and household recycling practices. Lessons all...

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers....

In this statistics and probability worksheet, young statisticians solve and complete 13 different problems related to probability, percentages, and normal distributions. They consider data models, assumptions about the models, and find...

This exam is aimed at assessing college level organic chemists. Ten problems are to be solved and include drawing molecular structures, assessing degrees of saturation, ordering alkenes according to stability, and explaining chemical...

After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

What a waste! The last installment of a nine-part technology/engineering series teaches learners about medical waste disposal systems. Conducting a simulation allows individuals to understand how monetary considerations constrain waste...

Functions require an input in order to get an output, which explains why the answer always has at least two parts. After only three multi-part questions, the teacher can analyze pupils' strengths and weaknesses when it comes to...
