Students are given a coin to observe and make inferences about. Using a worksheet, they make two columns to list their observations and inferences in an organized manner. They develop a hypothesis based on one of the inferences and...

Fourth graders explore how the landscape of the planet can be changed by different elements of wind, water, ice and chemicals through hands-on activities. They examine pictures of areas around town and discuss anything they think is out...

First graders participate in a study of air pressure in which the investigate if air has the strength to lift heavy objects. They work in teams to develop a hypothesis about whether air in bags would be able to lift a stack of books....

Students conduct toboggan time trials to investigate the variables that have the greatest effect on toboggan speed. In small groups, they develop a hypothesis to test and perform three trials on the toboggan run for each variable.

Third graders gather information by questioning, forming hypothesis, collecting and analyzing data, reaching conclusions and evaluating results, and communicating procedures and findings to others. Then they demonstrate an understanding...

In this data collection worksheet, students read about how data is collected and organized. They also learn about a hypothesis. Students read through examples of different charts and then answer 23 questions pertaining to data...

Students examine buoyancy.  In this density lesson plan students form a hypothesis, collect data and draw a conclusion using the data. 

Students use the scientific method to make predictions about mold growth. In this fungus lesson, students use worksheets to help them illustrate predictions and graph mold growth from white to wheat bread. Students first...

Students investigate the process of erosion and factors that influence the rate of soil loss.  In this erosion lesson students formulate a hypothesis and analyze the results of their experiment. 

Pupils conduct experiments to learn about seed germination. In this seed germination lesson, students write a hypothesis for the seed experiment. pupils complete the experiment for seed germination and graph the data obtained from the...

Young scholars study how tectonic plates can produce earthquakes.  In this earthquake activity students use a model earthquake machine to explore hypotheses about earthquakes. 

Learners study seamounts and the processes that form them.  In this Gulf of Alaska lesson students interpret data and investigate a hypothesis.

In this geometry instructional activity, students read given sentences identifying the hypothesis, and conclusion. They rewrite sentences usign the if-then form. There are 14 questions.

Students explore science. In this create science lesson, students come up with their own science experiment. They use their basic knowledge of hypothesis and procedure to come up with an experiment. This lesson includes background...

What's the difference between wind erosion and water erosion? Perform an experiment to study the effects of air on soil, as well as water and soil, and how effective it can be to place rocks on the soil. 

What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts. 

Does concentration affect the rate of a chemical reaction? Science scholars observe and control a chemical reaction in an interactive simulation. The resource allows pupils to add atoms to the reaction vessel and monitor the reaction's...
