Counting and cardinality, measurement, and measureable attributes are all discovered in this activity from Peg + Cat. Your child can earn badges as they complete a morning routine with Peg and her best friend Cat.

Students will learn about the architecture that is in place to enable GPS and how to interpret data for a station's position. They will develop a time series plot and use the data to see that the Mid-Atlantic Ridge is rifting Iceland....

What is an atlatl? Learn how this Aztec dart throwing tool can be used to teach young scholars such things as distance, radius, and linear and angular velocity. Curriculum strands are provided for each of the many lesson plans for...

Students explore the value of biodiversity, the impacts that humans are having on the Earth's biodiversity, and measures that can be taken to preserve biodiversity.

Measuring the voltage in a circuit is like measuring the drop in pressure across two points. Learn more with this tutorial.

Measuring voltage drops across resistances in series-parallel circuits requires an understanding of both series and parallel circuit behavior. Learn more with this tutorial.

This investigation will help students learn that different geologic materials have different characteristics.

Students visit a 2nd and a 4th grade class to measure the heights of older students using large building blocks as a non-standard unit of measure. They can also measure adults in the school community. Results are displayed in...

Students learn about and use a right triangle to determine the width of a "pretend" river. Working in teams, they estimate of the width of the river, measure it and compare their results with classmates.

Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed...

Students plant sunflower seeds in plastic cups, and once germinated, these are exposed to different conditions of light levels and/or soil moisture contents. During exposure of the plants to these different conditions, students measure...

In this interactive activity from NOVA Online, learn about a type of exploding star - a Type Ia supernova - that is so bright that astronomers can measure the distance to the galaxy in which it resides, and even learn which elements make...

A detailed overview of the Earth's climate, with explanations about the difference between weather and climate, dendrochronology, palynology, and how Earth's climate has changed over time. All information is reinforced through pictures,...

The learning resource discusses units, dimensions, and measures used in Chemistry. Some topics explored are dimension, symbols in metric units and symbols in English units. The activity consists of definitions and explanations.

In this activity, students will use bearing measurements to triangulate and determine objects' locations. Working in teams of two or three, students must put on their investigative hats as they take bearing measurements to specified...

In this activity, students will learn how to read a topographical map and how to triangulate with just a map. True triangulation requires both a map and compass, but to simplify the activity and make it possible indoors, the compass...

Celestial navigation is the art and science of finding one's geographic position by means of astronomical observations, particularly by measuring altitudes of celestial objects - sun, moon, planets or stars. This activity starts with a...

Accuracy of measurement in navigation depends very much on the situation. If a sailor's target is an island 200 km wide, sailing off center by 10 or 20 km is not a major problem. But, if the island were only 1 km wide, it would be missed...

Using inquiry-based learning, students work in groups to devise metric conversion factors after analyzing example calculations. By finding inaccuracies in the problems given, students zero in on the correct methods of doing conversions.

Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. They measure the severity by how far the landslide debris extends into model...

Through a series of activities, students discover that the concept of mechanical advantage describes reality fairly well. They act as engineers creating a design for a ramp at a construction site by measuring four different inclined...

Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual...

For this activity, students will be given a set of materials: cardboard, a set of insulating materials (i.e. foam, newspaper, etc.), aluminum foil, and Plexiglas. Students will then become engineers in building a solar oven from the...

Student teams locate a contaminant spill in a hypothetical site by measuring the pH of soil samples. Then they predict the direction of groundwater flow using mathematical modeling. They also use the engineering design process to come up...
