Generating Hypotheses and Experimental Design 1
Here is a thorough exercise in forming hypotheses for scientific investigations. Young scientists consider factors that may be related to the question they would like to address. They think through measurable changes that may result from...

Testing a Hypothesis
Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...

Making Observations and Generating Hypotheses
Young scholars practice how to approach a problem scientifically. They use their senses to make a detailed description of a natural object and to generate hypotheses about the identity and features of the object hidden within a box.

TE Activity: Bubbling Plants
Students study a way to quantify the process of photosynthesis during a given time using the Elodea plant. They design a hypothesis that they test in the hands on activity. They compare the amounts of photosynthesis that occur during low...

Beans and Birds: A Natural Selection Simulation
Students solve the following problem concerning the evolution of seed color in pinto bean plants: "How does natural selection change the frequency of genes or traits over many generations?" They use the constructivist approach to...

The Scientific Method
First, ask a question and then, do research. Next, form a hypothesis, and conduct an experiment. Make observations, gather and analyze data, and then state a conclusion based on the results. This is the scientific method, and here is a...

8th Grade Earth Science: Density
Learners draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.
Carnegie Mellon University
Lab Report
A set of instructions and a 100-point grading rubric have been designed for writing lab reports. Appropriate for middle schoolers, this lays out what to include for each of the six steps in the scientific method: title, hypothesis,...
