What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

A greenhouse provides additional warmth and protection to the plants inside, but what if the greenhouse gets too hot? Pupils discuss and experiment with the difference between natural and anthropogenic greenhouse effect. They measure the...

Maps are great for helping you get where you're going, but what does that place actually look like? Geology scholars compare and contrast the features of topographical and geologic maps using an interactive lesson. The resource describes...

Is there anything better than hot soup on a cold day? Kids prepare either vegetable chowder or minestrone soup in an activity that features the use of the stove top.

Have you ever wanted to travel the world? Take a virtual trip with a geography lesson that uses longitude and latitude, the position of the sun, an astronomy app, and a classroom globe.

Immerse your young marine biologists in the world of marine animals. The lesson includes several activities that are age-appropriate for preschoolers and kindergartners, including coloring pages, gluing feathers and sand onto paper...

Collections of data represented in stem and leaf plots are organized by young statisticians as they embark some math engaging activities.

Lateral area and surface area are simple concepts, but calculating them is not as easy! Using formulas, learners calculate lateral area and surface area for the same three-dimensional figures. The resource discusses the formula variables...

Temperature rises and land disappears! Through a lab exploration, learners understand the effect of temperature increase on water similar to the effect of global warming on our oceans. As they heat the water in a flask, they measure the...

Here is a collection of 22 multiple-choice questions on topics from the physical and life sciences. Apparently they came from an 8th grade comprehensive science exam and have been released for public use. They may serve as a sufficient...

Learners draw triangles on their graphing calculators using the Cabri Junior application. In this graphing calculator lesson, students follow step by step directions to create triangles on their calculator. They identify the type of...

Sixth graders identify various angles by using pattern blocks. For this measurement lesson, 6th graders find out how many degrees are in each of the different angles of the various pattern blocks.

Fifth graders explore the required functions of the Geometer's Sketchpad. Using the computer software, they construct similar triangles and identify them by angles and sides. Students classify triangles. Afterward, they complete problems...

In this online math worksheet, students find the area and perimeter of rectangles. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific teaching tool!

In this online math worksheet, students determine the volume of cylinders given their dimensions. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific...

For this online interactive worksheet, students determine the missing length of a geometric shape and then check their answers.

Elementary schoolers learn about metric units and how they are used by engineers. They learn how engineers use the units to measure mass, distance, and volume. Then, they estimate measurements of units, and compare them to actual...

Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...

Middle school or high school physical science pupils will warm up to the topic of heat when viewing this set of slides. It covers heat transfer, measurement tools, phase changes, and more. Have demonstrations and examples of the tools...

Learners follow a series of instructions for drawing and coloring different shapes in order to learn the difference between the perimeter and area of a polygon. Then they are asked to find the perimeter and area of a 3x4 rectangular...

Pupils identify the characteristics of aerosols. Using remote sensing, they participate in an experiment in which they determine how the sun's radiation and elements in the atmosphere interact with one another. They also research the...

Students layout and frame-up a scaled-down model of a wall with one door and one window.

Fourth graders use triangle paper to design patterns using geometric figures and find the areas of those figures by counting units. Students are assessed by determining which figure has the greatest area and explaining their reasoning.

Students explore the concept of central tendencies. In this central tendencies lesson, students sort M&M's or Skittles based on color. Students graph their results. Students find the mean, median, and mode of their data.
