Student develop a hypothesis regarding the effects of either mowing or fertilizer upon the diversity of plant species in a grassland ecosystem. They set up experiment field plots and measure species richness.

Students examine each soil sample and record observations. In this biology lesson, students design an experiment to test soil flow rate. They write a lab report about the experiment.

Students determine the effects of an increase of the amount of nitrate and phosphate levels on the growth of algae. the development of a hypothesis is encouraged and students proceed to a conclusion based on their results.

Students create their own bird study in their own schoolyard using the scientific method (see Testing a Hypothesis in Join the Project). Students do research in the library, at a local college, or on the Internet to determine the...

Eighth graders define the boundaries of living organisms. They determine what makes something a living organism and identify factors that constitute "living." Pupils write a conclusion about the evidence they found that yeast is alive...

High schoolers design and conduct an experiment to test a hypothesis. They create a question/objective based on the results of their experiment that can be answered by performing a human clinical trial. Students write inclusion and...

learners investigate a natural factor affecting their everyday lives: daylight. First, they collect data on sunrise and sunset in their hometown, create a Microsoft Office Excel chart to help them understand the data pattern, and offer a...

Students determine which wind-up toy is the fastest. However, they can NOT race the toys. They must find another way. On the first day of the activity, students work in pairs or small groups to develop and write a plan.

Third graders complete a diagram of the revolution of the earth around the sun and write a one paragraph explanation of the factors that cause seasons.

Students design an experiment to test the effects of common fertilizers on grass growth. They write or present a laboratory report responding to their observations and consider how fertilizers may affect the soil environment.

In this experimental design and measurement worksheet, students answer questions about independent and dependent variables, they write hypotheses, they identify instruments that measure mass, weight, and volume and they calculate the...

Students as a class create a fountain using both coke soda, and mentos candy. For this science lesson, students test which combination of coke and mentos products produce the tallest fountain. Students use the scientific method to track...

High schoolers read a sample research proposal and create their own. They discover the type of information needed for others to reject or accept the proposal. They practice applying the scientific process to different situations.

Students research effigy mounds of Native people in Wisconsin. They create large models of effigy mounds in a given area based on factual information from their studies and research.

Students use an on line website to simulate the effects of light intensity and wavelength on photosynthesis. In this photosynthesis lesson plan, students determine how wavelength of light and intensity of light affect the rate at which...

Fourth graders explore evaporation by conducting an experiment.  In this water properties lesson, 4th graders examine the differences between two socks that get wet, one which is placed in front of a fan.  Students discuss why...

Fifth graders participate in a review discussion of the parts of a lever, resistance or load, fulcrum, and effort. Next, they complete activities at six experiment stations while collecting data that they share with the class. While...

Students study the different parts of a flower and their functions.  In this pollination lesson students study a flower under a microscope. 

In this constellation worksheet, students pick a constellation to track over time. They measure its altitude and azimuth at least three times. They make an experimental design for their research and plot their data.

Ninth graders conduct experiments to determine what affects the rate of a pendulum's swing. Working in small groups, they identify an independent variable to study and create an experiment to test their hypothesis. When tests are...

Fifth graders recognize the need to follow the scientific method carefully and be aware of variables in experiments.  For this airplane lesson, 5th graders design and test an airplane, and complete a data sheet. Students retest five...

Third graders review formulas for area and perimeter in quadrilaterals. They arrange pre-cut twine on a centimeter graph paper to create non-congruent quadrilaterals. They calculate the perimeter and area of each form.

Students examine the Q.& A. article found each week in the Science Times, focusing on how the answers present scientific data in a clear and logical manner. They write their own questions and answer other classmates' questions in the...

In this evaporation worksheet, students participate in an evaporation experiment involving several days and a container with water and a marker. Students journal each observation to see how fast the water evaporates.
