Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

In 1820, Hans Christian Orstead discovered the link between electricity and magnetism, which allows us to measure current and voltage. The simulation allows scholars to observe the inner workings of an ammeter and voltmeter as they...

Did you know physicists can identify new particles by observing the path they take in a particle accelerator? Scholars explore the variables that determine the direction and radius of the circular path different particles take. They...

In this experimental design learning exercise, students evaluate experiments using a design checklist. They suggest ways to improve the experiments and they identify all the components of the design.

In this experimental design worksheet, students are given a full comprehensive outline for designing an experiment. There are checklists included for each section of the experiment for students to use as a guide for properly completing...

In germination experiment worksheet, students conduct the following lab activity. Students determine the effects of another tomato on germinating seeds. Students answer the following questions to analyze their experiment.

Young scholars conduct an experiment to determine the percentage of sugar in various types of gum. They weigh the gum after chewing it to determine the amount of mass lost from each piece of gum, analyze the data, and create a graph of...

Seventh graders examine a teacher-created database and identify specific variables and develop hypothesis statements as to their possible effect. They create a summary statement either proving or disproving their hypothesis.

Students experiment bubbles. In this scientific method lesson, students identify variables used in proper experiment design. Students conduct experiments with different brands of dish-washing detergent to determine which brand makes the...

Students designs and conduct a scientific experiment that identifies the problem, distinguishes manipulated, responding and controlled variables, collects, analyzes and communicates data, and makes valid inferences and conclusions.

Young scholars experiment, observe, measure, and analyze what occurs during an exothermic reaction. They safely design an experiment, control variables, and properly dispose of materials.

Students watch a video show how to identify the independent variable, dependent variable and controls in an experiment; and design experiments that use controls to isolate a single independent variable and measure the resulting dependent...

Students explore the skills and information needed to complete a science fair project. They follow guidelines to create an document their science fair project.

Students predict outcomes of scientific experiment,.conduct a scientific experiment with control groups, and plant seeds to observe, measure, and compare growth across groups. They gather, record, analyze, and share data with other...

Students evaluate a hypothetical experimental design and attempt to improve upon it. In this scientific method lesson, students are presented with an experiment and are instructed to determine its flaws. They conduct their own...

Middle schoolers investigate the effects of soil temperature, water availability, photo period and other variables of the growth of purple loosestrife. They observe the growing conditions of plants and alter them by adding water,...

Young scholars conduct experiments to discover the various ratios of oil to popcorn kernels. They determine which amount of oil produced the most popped kernels.

Young scholars use a model experiment to complete an experiment on yeast. In groups, they identify the independent and dependent variables and use the scientific method to complete the activity. They record their observations and discuss...

Learners identify and test variables that may affect the accuracy of a rain gauge. They share findings of their research with the class in a 'mini-meteorology-convention'. They design an experiment with a control setup to test their...

Young scholars study the steps involved in the scientific method. They apply the scientific method to their science fair projects.

Review questions like these can be used in your biology, chemistry, physics, or earth science classes! They assess scientists' understanding of laboratory measurement tools including graduated cylinders, thermometers, and balances. They...

Students design an experiment to test the variables involved in the hatching of the Bruchid beetle.

Here is a handy handout to give any science class as a guide to writing lab reports. It is a blank outline that you can have aspiring scientists fill out when they experiment, or imitate as they record their experiments in a lab journal....

This interesting document suggests nine different activities for shedding light on photovoltaic cells. A bit of background information is furnished for you, as well as many, many resource links. Listed for each activity are a learning...
