Learners study pictures of seeds and the conditions in which they grow during their study of archaeobotany. They infer ancient plant use by looking at archaeobotanical samples. They determine the change of plant use by interpreting a...

Students analyze linear functions. In this algebra instructional activity, students create a linear model to relate coordinate pairs. They evaluate and solve equations.

Students use the Internet to gather information on tides and then use this information to determine the period of revolution of the moon around the earth (part 1) and the relative pull of the sun and the moon on the tides (part 2).

Sixth graders participate in a lesson that covers the reading and interpretation of a circle graph. They review the part of a whole concept for percents and student observe and practice using the circle graph.

Both a reference sheet and skills practice worksheet, this handout on common fraction rules reviews steps for adding, subtracting, multiplying, and dividing fractions. Twenty examples are provided to demonstrate these skills, and...

Students create a graph showing the growth of their manduca since it hatched. They make their own predictions about how it will grow. They answer questions to end the lesson.

Watch an episode of the TV show, NUMB3RS and then explore the mathematics of chain letters and pyramid schemes, both of which involve geometric progressions and exponential growth. They discuss why both are dangerous and illegal.

Students experiment with the basic functions of a spreadsheet. They practice using headers, footers, functions and fonts. They also organize information.

Students participate in an activity that demonstrates the principles and dynamics of food chains. They discover that the sun's energy is captured by individual plants and transferred to animals.

Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...

Pupils work in small groups to explore spatial relationships while building with color cubes. Students must identify positions of blocks to partner, recreate a model, and color a sketch of their structure appropriately.

A graph not only tells us who won the bike race, but also what happened during the race. Use this resource to help learners understand graphs. The commentary suggests waiting until the end of the year to introduce this topic, but why...

Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...

Traveling through space is an amazing experience, but it definitely takes a toll on the body. After reading an article and watching a brief video, learners perform an experiment that simulates the effects of zero gravity on the...

Students select at least 6 cities from around the world to keep track of their high and low temperatures over a period of time.

Learners replicate the teacher demonstrations by changing the variables and predicting the outcomes.

In this consumer math worksheet, students use the web to research and select a stock to buy.  Students track and graph the stock’s activity over a two week period.  The one page worksheet contains a blank graph and four...

Fourth graders investigate measurement of linear and curved surfaces. In this math lesson, 4th graders discuss how to measure curved surfaces and work with a partner to measure various curved surfaces.

Students investigate what happens when a coin is tossed a few times versus many times. They analyze, in groups, the data from tossing coins, and the Law of Large Numbers.

First graders use a calculator to total money quantities. They use plastic coins to represent the cost of an entire purchase. Students model specific dollar amounts and how to make change.

Students identify pollution around their local community. They discuss the sources of polution and categorize objects based on their properties. They discover ways to make changes to the environment and how to inform the public.

Fifth graders use Geoboards to demonstrate how shapes can be made by looping the rubber bands over the nails. They make a triangle on their Geoboards. At least one side of the triangle should be either horizontal or vertical. The picture...

Fifth graders record the amount of time they spend sleeping, attending school, watching T.V., exercising and doing homework. At the end of the week they graph all of their information and discuss how sleep impacts their learning....

Students construct a barometer and collect data on the changes in air pressure. They work is small groups using plastic tubing, corks, and green food coloring. They then use a formula to convert inches of mercury to barometric pressure...
