Measuring the Flagpole
Studets practice problem solving and comparison of quantities, ratios and prproportions. They develop a plan for determining the height of a flagpole complete with drawings and calculations. In addition, they complete a written...
Curated OER
Examining Samples and Asking Testable Research
Students formulate a testable research question containing a comparison and a
quantitative measure. They state the null and alternative hypothesis for a testable research question. In addition, they describe some of the abiotic
and...

Alka-Seltzer Cannons
Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...
Curated OER
Snow Goggles And Limiting Sunlight
Students build snow goggles similar to those used by the Inuit people. They create their version of the goggles to improve upon existing designs. Pupils compare the process used to invent snow goggles with that employed by the MESSENGER...
Curated OER
Where Do Plants Get Their Food?
Students think about the historical development of the scientific method. They design an experiment that replicates van Helmont's, using only specified materials. Pupils then improved upon van Helmont's procedure and also consider the...
Curated OER
Foodborne Illness Outbreak Investigation
Students demonstrate how epidemiological investigations of outbreaks are performed. They illustrate the principles of hypothesis formation and testing by epidemiologic study in the setting of an acute foodborne disease outbreak.
Curated OER
Diffusion
Students design and carry out an experiment according to the scientific method. The experiment must test the effects of time and concentration on the rate of diffusion of potassium permanganate into potato cubes. After performing the...
Curated OER
Scientific Method
Students examine the steps of the scientific method. They define related vocabulary terms, view a PowerPoint presentation, and apply and identify the steps of the scientific method for an online experiment scenario.
Curated OER
The Science of Color
Students use the scientific method to explore how to make different colors with paint. They problem solve ways to darken and lighten colors without using black and white paint. Students hypothesize how to create new colors, and describe...
PBS
Predicting/Making a Hypothesis
Students analyze information from a variety of sources in order to create a hypothesis about the origin of an interesting family artifact.They create alternative hypotheses based upon available information to demonstrate that some...
PBS
Observation
Students study making scientific observations . They conduct a "field study" in their attic and make observations about their family artifacts based upon physical attributes. In addition, they determine what characteristics of an object...
Curated OER
An Activity to Introduce Critical Thinking
Learners discover how easy it is to accept oulandish claims by witnessing a fellow student show that they have a form of ESP but is secretly working with the teacher. This demonstrations uses skepticism as a starting point for...
Curated OER
How Tall is that Tree?
Students apply their math skills to develop an accurate estimate of the height of a tall tree. Three different methods are outlined. All grade levels should be able to perform the shadow method and the proportional method.
Curated OER
Color Dots 2
Students develop simple observations. They observe bleeding of colored inks with water, to understand mixtures, and to make generalized inferences from their observations.
Curated OER
Bird Eggs
Learners perform an experiment with different types of bird eggs to determine what factors make them strong and able to stay on a cliff without rolling off.
Curated OER
How Do We Use Scientific Inquiry To Solve the World's Problems?
Ninth graders examine how a scientific investigation is performed. They read and discuss examples of various scientific experiments, design an experiment involving fast growing plants, and create graphs and charts to present their...
Curated OER
Which Brand of Air Freshener is Most Cost Effective?
Young scholars use scientific method to determine cost-effectiveness of air freshener, and create PowerPoint presentations to share their results.
Curated OER
Working with Questions
Students explore questions in a scientific context. They consider what makes questions testable. After reading short scenarios, students come up with their own testable questions about the reading.
Curated OER
The Great Jellybean Hunt
Young scholars explore natural selection and its influence on the populations to fine tune traits and characteristics. The acquisition of traits developed out of need is examined through a game played in class.
Curated OER
Polluting the Environment
Fourth graders construct mini-ecosystem, pollute the ecosystem, observe, collect, and record data on the effects of these pollutants on their ecosystem, organize data on spreadsheets, create graphs, and design presentations to share with...
Curated OER
The Blue Bottle: An Example of Teacher-Guided Inquiry
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.
