Students take a virtual trip to a Catfish Aquaculture Pond and analyze soil bacteria to determine how many nitrogen cycle bacteria are present. They graph the number of colonies present and use data to determine ammonium levels in the soil.

Ninth graders measure the insulation properties of different fabrics by immersing cans of water covered with fabric "socks" in an ice bath and measuring temperature changes. They then calculate heat loss and graph the data individually.

Students complete an experiment in which they demonstrate that air exerts a force. In groups, they create their own siphon and define air pressure. They estimate the time it might take to siphon various amounts of water. They collect,...

Learners explore coffee production.  In this cross-curriculum rainforest ecology lesson, students research regions where coffee comes from and investigate how the native birds in the rainforest are effected by coffee...

Students explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.

Students collect and interpret data to make predictions about the levels of ozone in the atmosphere. Using the internet to collect data students use their collected data to create a line graph for analysis. Students make mathematical...

Students demonstrate that setting of plaster and cement is a change, which involves a release of heat energy, use data collected experimentally to construct comparison graphs and analyze the graphs to make predictions about future...

Learners develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.

Students investigate growth rates of flowstone formations. They view a virtual field trip and discuss how flowstones form. They observe the cave fieldtrip and predict the growth rate for a cave formation. They graph growth rates and...

Students grow plants in soil representing that found in the Amazon basin. They compare results to plants growing in fertile soil and soil fertilized with leaf compost. Students chart, average and graph plant growth by height. Students...

Middle schoolers use the scientific method to conduct an experiment and use varied methods to gather background information. They correctly use lab equipment and prepare tables and graphs that organize, conclude, and present their...

Students observe the pistil growing into a tiny string bean-like seed pod. They then observe the development of the fertilized pods between Day 17 and Day 35 and record their observations by drawing and labeling, writing, and graphing. ...

In this motion worksheet, learners analyze motion maps and construct graphs using the data. They write mathematical expressions to show the relationship of velocity versus time and position versus time. They determine displacement using...

Students investigate the effects of acid rain by conducting an experiment with bean sprouts and graph the results. In this Environmental Policy lesson, students visit a museum to identify examples of foreign and domestic policy on...

Students measure oxygen percentages in room air and air exhaled after they perform various activities. They explore various websites, and record and analyze the data from the experiments.

High schoolers analyze how the Law of Conservation of Energy applies to the design and use of scissors. Working in groups, they determine the output work for a standard pair of scissors.

Students explore the concept of a quadrat study. Students select and investigate a site and conduct a quadrat survey. They take measurements, observe the area and analyze their findings.

Young scholars analyze their fingerprints. In this fingerprint lesson, students make prints and observe the patterns for arches, loops, and whorls. They write a brief autobiography about themselves titled "I'm Thumbody."

Young scholars explore various tree species. In this tree species instructional activity, students collect leaves on nature walks and use Internet sources to identify the trees that the leaves belong to. Young scholars graph their data...

Students explore the science of toxicology and the relationship between a toxic reaction (response) and amount of substance (dose). They observe two demonstrations illustrating the concept of dose-response.

Ninth graders investigate and describe ways that human understanding of Earth and space has depended on technological development. They describe and interpret the science of optical and radio telescopes, space probes and remote sensing...

Students participate in a lesson designed to illustrate these concepts using simple materials. They use Science process skills to observe, measure, predict, make inferences, and communicate while completing the activity. Proper safety...

Students test and identify soil and rock samples. In this rock and soil lesson, students video themselves gathering samples. Students test the samples and create graphs showing the results.

Students differentiate between high and low viscosity. Students collect, graph, and interpret data, then quantitatively measure polymer solids. Students experiment with a household example of an emulsion polymer.
