Young scholars formulate a testable research question containing a comparison and a quantitative measure. They state the null and alternative hypothesis for a testable research question. In addition, they describe some of the abiotic and...

Students study making scientific observations . They conduct a "field study" in their attic and make observations about their family artifacts based upon physical attributes. In addition, they determine what characteristics of an object...

Students practice analyzing skeletal remains for clues by using the Internet.  In this scientific investigation lesson, students research the La Belle shipwreck using the Internet and written materials, later completing a Skeletal...

In this introduction to chemistry worksheet, learners answer 9 questions regarding the study of chemistry. The first part is matching, then they "think like a scientist" and then they problem solve.

Students discover how easy it is to accept oulandish claims by witnessing a fellow student show that they have a form of ESP but is secretly working with the teacher. This demonstrations uses skepticism as a starting point for...

Students demonstrate how epidemiological investigations of outbreaks are performed. They illustrate the principles of hypothesis formation and testing by epidemiologic study in the setting of an acute foodborne disease outbreak.

Students will observe a property of water. In this inquiry-based properties of air lesson, students observe how a change in water pressure impacts the positioning of an eye-dropper in the water container and they make hypotheses about...

The best inventions come from a problem that needs to be solved! Given a container with holes in...

Learners explore characteristics of mass. In this scientific inquiry about mass lesson, students drop rocks of different weights from various heights and record the depth of the "crater" created.  Learners record their findings on a...

In this scientific investigation worksheet, students use "magic tubes" to make observations, hypothesize, study variables in experiments, write procedures, and draw conclusions.

Students build a water filtration system. In this water quality lesson, students work in groups to construct water filtration units that can purify contaminated water. This lesson is part of a larger unit on water quality.

Students observe the production of gas as an effect of photosynthesis. In this biology instructional activity, students perform an experiment with pondweed and make measurements and predictions about photosynthesis and the plant.

Students examine and sort seeds. In this life science lesson, students make general observations of a tub of seeds, then develop sorting criteria for sorting the deeds. Lesson includes extension activities.

Students conduct a series of experiments to observe factors that impact molecular movement. In this molecular chemistry lesson, students drop food coloring in water with different properties (hot, with ice, with alcohol) and observe how...

Students observe mold growth on bread. In this mold growth lesson, students place bread in various locations and in various conditions to investigate how location, moisture, temperature, and other variable impact the growth of mold on...

Students test the adhesive strength of different tapes. In this adhesive lesson, students conduct an experiment to test the shear strength of the adhesives, take measurements, record data, and draw conclusions to explain each product's...

Learners test the stickiness of natural substances. In this adhesion as a property of matter lesson, students build a tool to test the adhesion of natural "glues" such as honey, peanut butter, flour and water paste, and jelly. Learners...

Students compare the absorbency of a regular diaper and a swim diaper in fresh water and salt water. In this absorbency lesson plan, students mass the diapers and place them in water and determine the change in mass. They do the same...

Students explore matter. In this physical science instructional activity, students role play the 3 states of matter forming "liquid" molecules and "solid" molecules with teammates. Students perform an experiment in which the result...

Students produce a newspaper describing the times during which Charles Darwin introduced the theory of natural selection. In this evolution lesson, students make observations and explore the role of observation in Charles Darwin's work....

Students demonstrate how digestion occurs. In this biology lesson, students compare the mass of sandwiches before and after addition of HCl. They collect data and formulate conclusion based on experimental results.

Here is a collection of 22 multiple-choice questions on topics from the physical and life sciences. Apparently they came from an 8th grade comprehensive science exam and have been released for public use. They may serve as a sufficient...

There are so many topics touched upon in this Jeopardy-style science game, that it is difficult to classify! The categories include electricity, matter, ecology, earth and space, and scientific investigation. This would best be used at...

In this chemistry vocabulary instructional activity, learners use their textbooks and dictionaries to find the definitions to 20 terms associated with chemistry.
