Students discuss situations when it is useful to know exact weight of object as opposed to estimated weight, estimate weight of various items, weigh them on scale using ounces and pounds, and compare their weights on Guess Your Best...

Students explore weight. For this math lesson, students predict which item weighs more and discuss how they arrived at their decision. Students weigh several items to determine which weighs more.

Fourth graders measure wind speed, air pressure, humidity, temperature, and wind direction. They compare their observations with those of actual weather forecasts.

Students calculate the amount of food calories found in an individual peanut. In small groups, they set up the experiment so that a burning peanut will heat water above it. Using the temperature change and volume of the water they...

Students discuss energy resources. In this energy lesson, students predict which item: the plastic cup, metal soup can, or foam cup, will keep water warm for the longest time by measuring the temperature in each item every...

Students study the water quality of a stream in their area, by measuring the temperature, pH, alkalinity and conductivity. They integrate biology with earth science when using the microscope to study the living organisms in the water.

Learners examine the interrelationship between trees, soil and people focusing on urban areas. They collect and analyze data about trees in their research area.

Pupils investigate the effect of different container materials on heat transfer; draws a conclusion about the best insulator; and applies concept to a new, seemingly quite different problem.

Learners study the quality of water by running chemical tests on the water. First, they measure pH, temperature, phospates, and nitrates in tap (drinking) water and an outdoor water sample. Then they post and evaluate the results of...

Students demonstrate that light and dark colored objects absorb the sun's radiation at different rates. They experiment with the temperature change of water in two locations and discuss the results.

Pupils analyze data to determine the effect of thermal pollution on a certain species of fish. They graph temperature and dissolved oxygen and make inferences on the impact a change in temperature could have on the fish. As a class they...

Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...

Students view infrared images of a blowing hair dryer, a Popsicle, and a toaster. They discuss the images and ways they are different than visible light images. Students view a temperature scale and discuss which parts of the item are...

Students identify foods that are made from wheat. They use a line graph to explain measurement. They identify foods from the food groups and explain how temperature, prefcipitation and natural resources affect the growth of wheat.

Students select at least 6 cities from around the world to keep track of their high and low temperatures over a period of time.

Students examine what happens when air temperature drops and gets closer to the dewpoint. They perform a lab activity which illustrates the effects on humidity, precipitation and barometric air pressure.

Students examine the YSI and the water properties that it measures. They identify the different properties of water pH, DO, temperature, turbidity, and salinity and determine why it is important for them to test these parameters.

Fourth graders brainstorm a list of words associated with weather. In groups, they sort the words into categories and observe the weather in their area for a month. To end the lesson, they compare the barometer measurements for a...

Students investigate the properties of water. In this states of water lesson, students explore how water goes from liquid to solid and back to liquid again. Students use measurement, observation, and communication to describe the change.

Young scholars answer questions about how microorganisms can affect our food supply and how they can be controlled. The first set of inquiry activities are directed by the teacher. Subsequent activities are based on students generating...

Students study the following: For centuries, people have been challenged by the mysteries that lie beneath the blue depths of our ocean planet. Very little was known about the ocean until late in the nineteenth century, although nearly...

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...

Pupils compute the area of triangles in a computer program. For this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.

First graders complete a variety of experiments with solids, liquids and gases. They read books about matter, identify the characteristics of solids, liquids and gases and the sort and classify a variety of matter. Students make...
