Out with the old and in with the new. Learners use a set of prices of computer monitors from 1994 to make a prediction. They then use one current price and what they know about the old prices to make a more recent prediction. Their...

It's imperative to be as precise as possible. Future engineers learn about precision by building a cardboard machine. The base, corners, handles, and paddles must all be assembled with precision or the machine won't work.

Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.

Starting with a paragraph of information presenting the different ways we can observe planetary objects, pupils work through these instructions to see how they can observe and measure angles.  Your class will discover how these...

The humble soda can gets the geometric treatment in an activity that links math and science calculations. After a few basic assumptions are made and discussed, surface area calculations combine with density information to develop an...

Third graders describe the difference between area and volume and also explain how various units of measure relate to one another.

Junior designers brainstorm the elements that a bedroom might have, such as a bed, television, and dresser. They identify which items are needs and which are desires. They practice measurement skills in the classroom by determining its...

Watch the excitement grow as learners experiment with homemade rockets. Pupils create their own rockets from a soda bottle and experiment with launch angles. They discover the launch angle has a significant effect on the distance the...

What does translating points on a number line have to do with solving inequalities? Young mathematicians first learn about translations of points on a number line, and then use this information to solve linear inequalities in one variable.

Help the local elementary school fix their playground by calculating the amount of sand needed near the swing set. The problem practices setting up proportions and ratios with three different options for solving. You can chose the option...

It's all relevant, really. Individuals use the scientific method to learn more about elements, atoms, and their placement on the periodic table. They conduct experiments using materials common in nature to explore how elements affect our...

Designers measure their own rooms and produce a scale drawing. They use the Internet to visit sites to find the costs of purchasing new carpet, paint, or anything else they would like to add to their room. Using a $1500 budget, they will...

Investigate equivalent fractions with your class. They compare and order fractions. Then they work cooperatively in groups to experiment and problem solve with fractions using a game format. Multiple resources are provided.

Budding artists experiment with balance and movement as they learn about Alex Calder and his kinetic sculptures. They'll view several of Calder's pieces and review biographical information, then they'll work through the artistic process...

Bring your math class around with this task. Learners simply identify parts of a given circle, compute its radius, and estimate the circumference and area. It is a strong scaffolding exercise in preparation for applying the formulas for...

Mapmaking was a very important element in successfully planning attacks on enemies during the Civil War. Guide pupils through the process of pacing to find the average length of their steps, measure the distance between one object...

Finding the sum of the measures of three angles is easy, unless you have no clue what the measures are. Learners use an interactive diagram to see a geometric problem in a different way. A set of challenge questions takes them through...

Sports fans will really enjoy this unit conversion assignment. A table of standard measurements for football-related equipment is presented as the data for solving six word problems. For all of the problems, players will need to convert...

Make sure your scientists are reporting their work effectively by providing them with a reference for their lab reports. The first few pages of this resource detail each element of a lab report, and the last few pages provide an example...

Given a prepared database of European countries, sixth graders sort the countries in ascending order by elevation and identify the five countries with the highest elevations. This cross-curricular lesson combines elements of computer...

Students explore the realms of measurement. In this math lesson plan, students analyze and solve problems in which rectangles with identical perimeters are compared to maximize or minimize area. This lesson can be extended for algebra,...

Students design a battery, identify and label the anode, cathode, electron flow, ion flow, oxidation & reduction reactions, chemicals used including the location of each;and distinguish between anode materials with regard to energy...

Here are the instructions for leading your advanced chemists though the process of measuring the nonvolatile components in a sample of paint. No student handout is provided, so you may want to create one based on the procedure explained....

Children explore fractions on a conceptual level by making individual quilt squares. Each student works with small paper swatches to divide them into pieces that represent a given fraction. The class is then separated into groups and...
