Young scholars compare drip rates at several different locations throughout a cave. They observe, first hand, the heterogeneity in flow paths present in karst aquifers such as the Edwards aquifer.

Students graph water temperature using probe software and a Palm on a class field trip to a lake or pond. Emphasis is placed on collaboration with high school science students and the use of ImagiProbe software.

Students plan and design their project idea and demonstrate what their product looks like. They make a set of instructions describing a process that could be used to manufacture this product in an industrial setting. Students are given...

Students research tree leaves. In this tree leaves lesson, students observe, measure, and sort tree leaves. Students examine leaves individually, in groups, and in relationship to the entire tree.

Students estimate the energy output of the sun. They estimate how much power sunlight the sunlight provides to the earth. They build a simple device to measure the amount of solar radiation the earth receives from the sun.

Students discover the differences between weather and climate in this long-term instructional activity introduction. They create rain gauges and practice reading rainfall measurements, view a website showing the cloud cover in their...

Students use the blooming of tulips as a tool to measure spring's journey north. They predict when tulips bloom at 13 selected Journey North gardens in various geographic regions.

Pupils work together to determine how fast trees go. They make predictions and complete simple measurements. They answer questions to end the instructional activity.

Students research the effects of sodium bentonite being combined with water. They discuss the reasons why this chemical is used in landfills. They measure the swelling index of sodium bentonite clay.

Students measure the daily growth of plants in this technology-based science lesson that uses Timeliner to record student data. The lesson allows students practice at basic computer skills (typing/data entry).

Students examine a powerful tool that can be used in the study of motion. They use VideoPoint to measure an aspect of an organism's motion: speed, acceleration, center of mass.

Middle schoolers discuss why the ocean is salty. They discuss what salinity is. Students are told that is they want to know how much salt is in a body or water, they would use a special scientific tool. They complete an Estuarine Layers...

High schoolers study the use of a nautical chart and how to obtain information from it. They describe and differentiate the basic topographic characteristics of a chart and demonstrate the use of nautical tools used to plot fixed points...

Students define what population is in their own words. For this biology lesson, students explain different ways to measure population density. They interpret population graphs.

Students, in groups, evaluate conditions outside the building and inside the classroom using thermometers, barometers, anemometers, etc. They compare interior and exterior conditions. They consider and discuss factors that contribute...

Students identify and classify soil ypes according to data on the soil triangle. Given examples, students identify soil conservation practices, using criterion assessment instrument. When giving a case situation involving soil...

Students differentiate physical and chemical change. In this chemistry lesson, students list examples of those changes. They apply what they learned in a Jeopardy style team game.

Learners, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and effects on a...

Students measure the lengths of their bodies and various body parts to determine the relationship (or lack of one) between body part length and the length of the entire body. A spreadsheet program is suggested for data collection.

Students practice using the different tools on the Sheet Metal toolbar. For this engineering lesson, students create a sketch given a set of procedures to follow.

Pupils watch a video show how to identify the independent variable, dependent variable and controls in an experiment; and design experiments that use controls to isolate a single independent variable and measure the resulting dependent...

Students calculate the amount of everyday food products or liquids that would need to be consumed in order to become toxic. By using unit analysis, they calculate the amount of certain common food items that would need to be consumed in...

Tenth graders discuss the techniques and tools scientists use to study about the earth, including techniques used to determine geological time scales. They share their personal experiences of earthquakes and volcanoes.

Young scholars pick up science knowledge as they track and examine natural disasters. They keep a daily journal of results and reflections. Students get to follow a real tornado chaser and learn thunderstorm formation. They incorporate...
