In this hypothesis worksheet, students do a group activity in which to understand the meaning and creation of a hypothesis. Using flashcards and the given directions, students must create a group hypothesis.

Students identify and analyze the various roles organisms play in food webs, populations, communities and ecosystems. Students assess the requirements for sustaining healthy local ecosystems. STudents evaluate human impacts on local...

Students form a hypothesis for a water cycle experiment. In this water cycle lesson, students create their own environment with water and earth to study the water cycle. Students complete a handout to make a hypothesis and...

Third graders explore the idea of formulating a hypothesis and designing an experiment to test the hypothesis.

Students investigate the effect of a chemical (they choose) on the germination of seeds. They calculate % chemical concentrations in water, form a hypothesis, and discuss the ethics of using animals in biomedical research.

Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem instructional activity, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They...

Students observe a demonstration in which a bottle containing a colorless solution is mixed, turns blue, then becomes colorless again. They record observations, form and discuss hypotheses, and draw a conclusion based on the evidence.

Students identify sources of Food Borne illness and their prevention. They formulate hypotheses based on collected information. Pupils become aware of Nutrintional value of food. Students collected data are synthesized to formulate...

High schoolers determine the specific heat of unknown metals. based on their hypothesis and design proposal. They analyze the findings of the specific heat of the unknown metals. Students complete this by questions, hypothesis,...

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...

Learners 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...

In this rate of solution learning exercise, students determine how quickly a solute dissolves in a solvent by testing one independent variable such as temperature, particle size or the amount of stirring. Students design their...

Students consider their attitudes toward concrete and abstract violence in the media before developing hypotheses that assess the effect of gender and age on people's attitudes toward such violence and designing a survey to test those...

Second graders classify objects and create hypotheses regarding their magnetic properties. They watch a video about magnets and finally use a magnet to test their hypotheses created earlier.

Students describe the components of an HVAC system and determine which factors influence how efficient the system can be. They work together to develop hypotheses about the systems and their cost effectiveness and efficiency.

Learners investigate chemical and physical changes in reactions. In this chemical and physical change lesson plan, students mix 6 different white substances with water, vinegar and iodine. They make hypotheses about each substance and...

In this scientific method and paper airplanes worksheet, students go through the steps of the scientific method to determine which paper airplane design is best. They complete 8 steps of the scientific method including stating the...

Students investigate how to use Moh's Hardness Scale. In this geology activity, students examine several minerals and develop a hypothesis about which mineral is the hardest. Students use the Moh's Scale Identification Chart to determine...

Students investigate how seeds are dispersed on land.  In this plant biology lesson, students use a dissecting microscope to study strawberry seeds and dandelion seeds, they draw what they see, then create a hypothesis on the seeds...

Middle schoolers formulate hypotheses on wave behavior and test them. In this physics lesson, students compare and contrast transverse and compression waves. They determine the wavelength of transverse waves.

Students demonstrate the greenhouse effect. They recognize that relatively small changes to our environment can stimulate significant climate changes. They determine that the "scientific method" is a process of testing hypotheses and...

Students act as archeologists to examine, describe and hypothesize about 'artifacts' they have been given for their archeological interpretation. They rely on the descriptions and hypotheses of other students to identify the 'artifacts'...

Learners work in small groups to brainstorm hypotheses about mysterious science photographs, read and interpret answers to the science photographs, cooperatively develop a set of clues for the images and develop their own science photo...

Young scholars form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.
