Fifth graders conduct an investigation into water purification during a role play situation in an Amazon Rainforest. They design a scientific experiment for cleaning and filtering water.

Fifth graders plan and conduct investigations to identify and record tree species. They complete Forest Plotter and write about tree species found and draw pictures of them.

Students investigate and experiement with a 9-volt motor. They will use the connecting wire and battery pack to discover fans.

Students investigate the stages of the Monarch butterfly and its life cycle.  In this butterfly life cycle lesson, students discuss when, where, and how the Monarch butterflies lay their eggs.  After discussion, students...

Learners practice graphing relationships between variables by studying topics such as exponential growth and decay. They conduct a series of numerical experiments using a computer model and a variety of physical experiments using mold,...

Students record data, make observations, and share in experimentation and discussion of numerical experiments.

Students explore air and clouds by watching demonstration. They perform an experiment to measure air pressure changes.

Students read and relate the poem, "Clouds" by Aileen Fisher to a demonstration on cloud formation. They create clouds in jars using ice water and matches then discuss the ways clouds can be used to predict weather.

Students estimate how many children in their class it would take to equal the mass of one adult bear. They then weigh and record their measurement on a chart to check their estimate.

Students identify the characteristics of aerosols. Using remote sensing, they participate in an experiment in which they determine how the sun's radiation and elements in the atmosphere interact with one another. They also research the...

Students practice graphing a linear equation and a parabolic equation. They work cooperatively to select numbers, including fractions, which they will put into ordered pairs. Students explain their process to the class, discussing what...

Third graders measure distance using nonstandard units of measure. In this measurement lesson, 3rd graders measure a given distance through the use of the game "Mother May I?" Student gather and compare data on how many "giant steps" and...

Students discuss problem and take turns in pairs, one tossing the coins while the other guesses whether the coins land with the same side up or different sides up. They record the results of each guess as same or different.

Students practice using a different type of measurement each day. They complete data sheets to record their information. They practice estimating the weight of an object as well.

Students use probability to determine how likely it is for each tree in a small forest to catch on fire.

Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.

Students explore energy by participating in a science lab in class. In this energy form lesson, students define the different types of energy such as light, mechanical and sound while examining energy measuring tools in class. Students...

Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.

Students create a glossary of geometric terms while exploring tangram manipulatives.

Students examine the history of equal temperament, the modern standard of tuning a piano. Proportion calculations of octaves and perfect fifths are utilized to calculate the frequency of each note in a major scale.

Students participate in lab activities in which they examine the radon level in homes. They demonstrate through convection currents how radon moves through a home based on temperature. They predict what they believe will occur during the...

Tenth graders discuss sides of a shape and how to collect data correctly. In this geometry lesson, 10th graders examine shapes and count the surfaces on the shape. They read the history of Mobius Band and relate it to surface area.

Pupils discuss the subject of coins and heads and tails. They work in groups to solve Fran's problem concentrating on the fact that the coins are in a row. Any group that finishes early can try the Extension problem.

Students observe examples and discuss how to interpret them. They then brainstorm examples of possible questions students could use to create a table. They take time to formulate a question and collect data.
