Students use graphs and plots to measure the basal area and stocking levels.  In this graphing instructional activity students work in the field the use their data to help them complete a lab activity. 

Primary learners participate in activities that help them explain how different things are measured. They create their own access number chart.

Learners work with measurements of length, area, and volume capacity of a liquid. They watch a teacher demonstration of both English and metric units before they estimate and take actual measurements of assigned items a three different...

How large can a population become? The fifth installment of a nine-part unit teaches young ecologists about limiting factors that determine the carrying capacity of species in the Sonoran Desert. Here is a PowerPoint to help present this...

Thirsty plants soak up every bit of a rainfall, but what happens to the rain that hits the roof? Calculate the amount of rainwater from your school's roof with an Earth science activity, which brings measurement skills, observation...

Students explore the size of one ton. They research the capacity of sialing ships and estimate the volume of rectangular prisms. Students perform activities to discover the capacity of a classroom in tons.

Students design and conduct an experiment to compare the water-holding capacity of sand, soil, and moss. They measure the change in weight for each material after adding the same amount of water to each material.

Students study the function of lungs. In this lung function lesson, students complete an experiment using balloons to study the way lungs work. Students study a diagram of their lungs and make a hypothesis for their lung capacity...

Learners determine their lung capacity by completing a science experiment with a bottle of water. In this lung science lesson, students discuss the lungs' purpose. Learners complete an experiment to determine their lung capacity using a...

As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

Pupils use scientific methods to investigate the effects of overpopulation of seed plants on growth in a limited living space. Students relate seed plant population findings to that of other organisms.

Students design and conduct an experiment to test their ideas about how to speed up or slow down the rate of an enzyme-catalyzed reaction. They have access to an array of physical and chemical factors that might influence enzyme...

See how changes in initial populations and parameters affect a biological community. Individuals use a special software program to simulate a desert community with five species. They adjust initial populations to see how the community...

Students create a model of a salt marsh to discover the impact of pollution and human activities on water-based habitats including bays and the ocean. They recognize the relationship between natural and developed areas. Students impact...

Students explore the variety of ways to use solar energy. They investigate the thermal energy storage capacities of different test materials to determine which to use in passive solar building design. They explain how passive solar...

Students create an airplane by listening to directions. They also to measure the pieces for the airplane and compare and contrast their test flights.

How do robots assist ocean explorers in collecting data and images? The final installment in a five-part series has science scholars examine underwater images collected by robots and identify the organisms shown. Groups then calculate...

Students watch a segment of the PBS video which show the lemurs' ability to jump. In pairs, students collect measurement data involving each other's length of a standard step, a standing broad jump, and a long jump. They record their...

Students investigate water usage at school and at home. They use graphs and tables to evaluate water usage. Students describe possible water conservation measures. They use graphs and tables to relate data as part of a written report.

Students work with thermometers to complete problems about temperature. They investigate cooling patterns, how location affects temperature, and what happens when water having different temperature is mixed. They measure temperature in...

Students pour, label, streak, seal and store plates in an incubator. They identify areas in their environment that provide a rich fauna of microbes once they have been swabbed. They identify areas of contamination through a laboratory...

Students examine different types of soil have different capacities for retaining rainwater. In this science lesson, students determine that if the soil in an area will not hold enough rainwater there may be a flood. Students experiment...

Pupils estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
