It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Explore the current television rating system, its content descriptors, and the new V-chip technology that more readily allow parents to control their child's television viewing. Help learners develop a survey that will determine the pros...

The class examines the new tax cut plan proposed by President Bush. They practice calculating income tax rates and interpreting the data. Then they research topics that are of interest to them related to taxes.

An engaging, and not to mention attractive, lesson plan has prealgebra and beginning algebra scholars examining linear relationships. They consider the rising water level as a swimming pool is being filled. They do so by charting and...

Inflate your knowledge, not the economy! Pupils learn more about inflation with detailed worksheets and exciting activities such as role play, an interactive PowerPoint presentation, and a project in which they design...

Enzymes play a role in almost every function in the human body. Scholars explore three variables related to the use of enzymes. They observe a catalase reaction, experiment with substrates, and examine reactions rates. 

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Pupils explore linear functions in this lesson plan when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the concept of...

Students illustrate a schematic circulatory system of a human body including heart, lungs, arteries, veins and capillaries. Next, students conduct an experiment to increase understanding of the relationship between heart rate/pulse and...

Students examine human blood flow by comparing the pulse of athletes.  In this human body lesson, students discover the equation for finding the cardiac output from a human heart.  Students identify heart rates of accomplished...

In this Monetary Policy worksheet, students solve problems with varying reserve requirements and interest rates, then complete balance sheets for the Federal Reserve Banks.

Which requires more water--a bath or a shower? Given some specific criteria, learners attempt to answer the question. A video shows how long it takes to fill a gallon container using a faucet and a shower head. Using that information and...

Let's hope class participants don't get motion sickness. In the lesson, class members first solve motion problems using tables and graphs. They then use algebraic techniques to solve motion problems.

You won't find yourself racing the clock on such a great task. Scholars use video information to predict the time left on a crosswalk signal after a pedestrian crosses. The video shows the time left on the counter, and individuals must...

Am I going to catch it? Individuals time how long it takes them to walk, jog, and run a given distance and calculate their speed. They then research two animals and find their speeds. Using a chart, pupils compare the speeds of the...

Who doesn't like a snow day? Learners watch a snow accumulation over a span of 10 hours. They use that information to make a prediction of the total snow that fell during the 23-hour snowfall. Will it be enough to cancel school?

And he's ... safe? ... out? It's up to your scholars to decide! Provided with the speed of the runner and ball, learners develop a plan to determine which reaches the base first, the ball or the runner. While the distance from home to...

Capture the engagement of young mathematicians with this upper-elementary math lesson on measuring time and distance. Using Google Maps, young scholars first measure and compare the distance and time it takes to travel between...

Grow an equation for the exponential graph. Given a graph of an exponential function, class members write the equation of the function provided. The graph labels two points on the graph: the y-intercept and the point where x is one.

Use the constant of proportionality to relate the independent variable to the dependent variable. The eighth installment of a 22-part series instructs pupils to use the equation to find the constant of proportionality and then write the...

Sixth graders read a given passage silently. The student then reads the same passage orally to a partner. The partner records the number of words pronounced incorrectly. The student then sets goals to increase oral reading speed and...

In this motion problem worksheet, students read story problems, write equations, and determine the speed, distance or time objects travel. They determine when two objects, traveling in opposite directions, meet, This three-page...

In this meter worksheet problem, students read a word problem and interpret a graph.  They use the derived information to determine time and distance.  This one-page worksheet contains 1 multi-step problem.  Answers are...
