How did ancient peoples determine the height of really tall objects? Young scientists and mathematicians explore the concept of using shadows to measure height in a hands-on experiment. Paired pupils measure shadows, then calculate the...

Measurement devices can be used to determine the height, length, or weight of all kinds of things, even plants and animals. This presentation acts as the basis for two estimation activities. Each activity requires the children to...

Estimate and explore the length and weight of classroom items using standard measurement and scales. Students will work in groups to determine appropriate measuring tools, weigh or measure items, and record their results on a data chart....

No, it really is okay to play with your food! Emerging scientists manipulate popcorn, eggs, and other household objects as they demonstrate multiple cellular processes. The activity, capable of modifications, is designed to reflect...

How big is that carrot? Why one hand span, of course. As an exercise in measurement, individuals trace their hand in their science journal and search the school garden for one object the same size as the span between their thumb and...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

Scientists could measure the diameter of the sun before they knew its distance. Scholars construct a simple mirror box to measure the diameter for themselves. They compare this measurement with the official size, listed in a...

Young chemists create gold nanoparticles as they learn to measure accurately with the metric system. They create an advertisement for the application of nanotechnology to complete the first lesson in a series of six.

Discover a world too small to see. In the activity, young scientists learn about nanotechnology and brainstorm ideas for new applications of it. They perform an activity to determine how surface area changes when objects are made smaller...

Both aerobic and anerobic respiration are introduced in this succinct PowerPoint. The chemical equations for both are included. The last slides give instructions for a lab activity in which pupils use a gas sensor to measure the...

Four fabulous activities immerse amateur astronomers into measuring objects that we cannot handle. The experiences are applied to NASA's Space Interferometry Mission, which will take measurements of planets around stars other than our...

Through a station rotation activity, scientists complete 9 chemistry activities to complete this interactive worksheet. Concepts include molar masses, percent composition, accuracy vs. precision, mass of an object, scientific notation,...

General chemistry class members engage in a mini-unit on mole conversions. Through nine lab activites with varying degrees of difficulty, they practice measuring mass and volume, molar calculations, and stoichiometry. Terrific...

Demonstrate how rain is measured. Pupils will use a rain gauge to measure the amount of rainfall during one week. Then record the data and discuss the results.

Exactly how small is a nanometer? Scholars investigate the scale of a nanometer by measuring classroom objects and converting these measurements to nanometers.

Enrich your study of living things with these cross-curricular math activities. Following along with the story Tillena Lou's Day in the Sun, learners will practice addition and subtraction, learn how to measure volume and length,...

Plant growth experiments offer rich, cross-curricular learning opportunities that can really excite and engage young learners. For this series, children work in pairs planting, measuring, and comparing the height of bean plants in order...

How does your class measure up? Young scientists create a scale drawing of the JOIDES Resolution in a collaborative activity. The lesson incorporates mathematical principles with deep-sea exploration to focus on enhancing measurement...

Combines mathematical measurement with gardening skills. Third graders hunt for worms in the garden and try to find the longest one. They also measure and weigh vegetables that they harvest from the garden, measure rainfall amounts,...

Who pilfered the pin? Scholars practice measurement skills as they solve the mystery of a stolen pin. They measure length, temperature, and mass and determine which of select suspects committed the crime. During the STEM hands-on...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Teach the masses about the metric system with this hands-on measurement lesson. Given a fruit or vegetable, learners estimate, measure, and convert its mass using the metric units gram and kilogram.

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...
