Learners define the term species, and graph species data together with previously collected data at the National Zoo. They interpret graphed data and recognize patterns in the streamside quadrant versus hillside quadrant. Students use...

Students formulate a hypothesis regarding the validity of the current status of the Arizona Hedgehog cactus as a distinct variety of cactus. They design a procedure to isolate DNA from the tissue of plants, given a list of chemicals and...

Young scholars complete a lab activity.  In this hardness of rocks lesson, students observe and touch various rock samples.  Young scholars determine if they can make a scratch mark on any of the rock samples and use the...

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Young scholars inspect a given problem and come up with a hypothesis. In this investigative lesson students come up with a hypothesis for a problem, test each hypothesis and evaluate how successful each one was. 

Students research a topic in the various fields of science that interests them. Using a computer, they type their information to use on their project and use a scanner to place pictures or articles in the document. They use the steps...

In this scientific method learning exercise, students record the steps of the scientific method in order and then respond to 5 multiple choice questions regarding the scientific method.

Learners role play scientists to prove a hypotheses. They determine whether or not walruses stay warmer in water or in air. Students also determine in which environment they lose more body heat.

Students evaluate the friction of tennis sneakers and redesign them to increase friction. In this physics lesson, students calculate starting, sideways and forward stopping friction. Using quantitative data, they prove that redesigning...

Students design and test paper airplanes to understand the concept of lift and how it affects flight. This technology-based Science lesson is excellent for use with upper-elementary and middle-level learners and uses spreadsheet software...

Environmental science classes read articles about two different scientific studies. One is about the effects of contraceptive chemicals on fertility, and the other is about how a pesticide may be reducing bone density in exposed...

Learners conduct an experiment to discover what happens to air when it is heated or cooled, discover that wind moves from a high-pressure area (an area of sinking air) to a low pressure area (an area of rising air).

Students discover how seed germination varies according to the soil type. In this soil science lesson, students discuss what plants need in order to grow and investigate various types of soil. Students use their senses to describe each...

How do people get sick? Youngsters explore the world of germs and microbes with a lab sheet and science investigation. After identifying the unhygenic practices in a picture of a kitchen, fifth graders conduct an experiment with bread...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Students observe leaves and their attributes and group them accordingly. In this science observation lesson students gather leaves and use them to become more familiar with seasonal changes and the cycles of our environment. 

For this digestion and nutrition lesson, 3rd graders test foods to find their vitamin content. Students test for starch and fats then compare their findings on charts and oral reports. The lesson concludes with a teacher directed...

Students connect the scientific method to real world situations. In this scientific method lesson, students discuss the work of Dr. Renshaw in making a diagnosis and connected to the scientific method.  Students view a website video...

Students explore the concept of the scientific method. In this investigative lesson, students investigate which direction the blades will spin on a gyrocopter. Student will practice using the scientific method to complete the investigation.

For this air pollution worksheet, students use an online simulation called "Smog City" to manipulate different conditions that affect air pollution. Students answer questions about the health effects at peak ozone levels for different...

Students recognize that artifacts are destroyed over time.  In this environmental factors on artifacts lesson, students experiment and observe through the microscope to find the environmental impact on artifacts.  Students make...

Learners discuss the scientific method and construct their own Mobius Strips. They examine their Mobius Strip, and write observations and a hypothesis on how many strips of paper they have when they cut the strip in half length-wise.

In this project instructional activity, 9th graders display their data, the make a graph and they answer analysis and conclusion questions on their experimental design project. They discuss the variables of their experiment, their major...

In this writing conclusions activity, students practice writing and evaluating paragraphs written at the end of an experiment. They are given a hypothesis and a results sentence and they write a conclusion.
