Class members analyze the water content in soil samples by drying out the samples and taking measurements every minute until all the moisture is gone. Scholars compare the initial weight to the dried weight to calculate the percentage of...

Compare sizes of microscopic items. Given a set of labels of microscopic objects, pupils try to place them in order from smallest to largest. Scholars then compare their lists to the actual comparisons along with the measurements of the...

String up a message. Pupils string together colored beads to code a word or short phrase. Each color represents one of the four DNA bases. Using a combination of three bases, learners create an amino acid that stand for each letter of...

Is there one right way to control infectious diseases? Learners determine the facts each stakeholder must consider when making their recommendations for controlling a disease threatening their area. They take into account public health,...

Students take an inventory of their own easily-observable genetic traits and compare those inventories with other students in groups. They then make data tables and bar graphs showing the most and least common traits in their group.

In this biology activity, students identify and describe a number of easily observable genetic traits and compare the traits they have with other students. Then they identify and describe that some traits are common while others are not...

Students attempt to design and build the most stable "earthquke resistant" structure. They create model buildings and test them on a shake table to see which design holds up the best.

Third graders explore how barrier islands work. For this erosion lesson, 3rd graders create barrier islands in stream tables and simulate wave action to see how it affects their island.

In this science learning exercise, students learn about surface tension by performing an investigation with drops of clean and soapy water on a penny.

In this earth science worksheet, 7th graders classify rock samples according to chart provided and physical properties of the rocks. They answer 2 analysis questions and formulate a conclusion.

In this finding epicenters worksheet, learners complete a table given the "P" and "S" wave arrival times of 6 different earthquakes. Students calculate the difference in arrival time of the waves, the distance to the epicenter, the "P"...

Students research water management strategies in Texas. They analyze projected demand for water in the year 2050, interpret graphs and tables and then discuss the data as part of a written report. They research and map the locations of...

Fourth graders investigate the process of water erosion. They observe the roots of a plant and discuss the concept of erosion. Next, in small groups they conduct an experiment to observe how water erodes soil on a stream table, and...

In this science worksheet, students look for the answers to finding the correct temperatures that match the location in the atmosphere.

High schoolers identify the elements that belong to the halogen family on the periodic table. In this chemistry lesson, students describe the common characteristics of elements in this group. They research about hydrochloric acid's...

In this codon learning exercise, students use a table showing codons in mRNA to determine how mutations will affect amino acid sequences. This learning exercise has 4 fill in the blank and 2 short answer questions.

In this earth science worksheet, students read 4 stories about hurricanes. They write short answers to 2 questions following each of the stories.

Students conduct and observe experiments in Newtonian mechanics, kinematics, and projectile motion. They analyze the motion of a ball rolling off a table, falling, and then bouncing. Students answer a series of questions analyzing the...

Students observe and collect data about the earthworm. In this observation of an earthworm lesson plan, students use an earthworm to determine the effects of light and incline on the earthworm's behavior. They practice making...

Students show how earthquakes affect sea waves. In this tidal waves lesson students use a rubber mallet on a table to create waves in a box on top of the table. They experiment with striking the mallet in different locations on the...

Students discuss the effects of earthquakes. In this earth science lesson, students create earthquake models and earthquake-proof buildings. They construct their own seismograph.

Students will examine how floods work and why they can cause so much damage and destruction. They use a stream table to observe the processes that lead to flooding and the effects of floods on human-made structures. Includes a guide to...

Students build simple stream tables and vary the angle of the stream tables in order to simulate different flow rates and compare the results. They observe various features formed in a stream table by flowing water and compare these to...

Young scholars simulate the impact of fluctuating river volumes on structures and landforms. They experiment with table top-sized riverbed models and water. Students consider how human design can help mitigate the effects of a flood.
