High schoolers investigate the cause of death of a fictitious school janitor. They develop hypotheses based on information discovered by examining the labels of household chemicals.

Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...

Students explain the use of different technologies based on their resolving power. Explain how technologies are used to solve scientific and health-related problems. Explain the concept of using right tool for the job and develop a multi...

Learners demonstrate how descriptive epidemiological clues can be used to make educated guesses as to what might be the cause of a disease.

When the sun's rays can't reach the producers in a food web, where does all the energy come from? Extreme environments call for extreme food sources. Young scientists investigate creatures that appear to get their energy from methane...

In this scientific method worksheet, students read over the basic steps of the scientific method and then apply those steps to a specific example. This worksheet has 8 short answer questions.

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

Students 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 the...

Students experiment to determine which bottle of soda has more dissolved carbon dioxide. In this solutions lesson, students use the scientific method to test the amount of carbon dioxide in bottles of soda. They identify and explain the...

Students will design a scientific investigation. For this engineering design lesson, students will set up an investigation, collect data and form a conclusion about bridge design. They will use common household items to construct their...

Student form and test hyptheses using indirect and direct observation. They launch marbles to determine the shape of a hidden object.

Learners determine the amount of sugar in various types of gum. They chew a piece of gum until it loses its flavor and leave it to dry in order to weigh it and determine the amount of mass lost, and describe an experiment to determine...

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...

In this physics worksheet, students tackle the hard questions about scientific theory and take a look at the First and Second Laws of Thermodynamics.

In this primes and prime factors worksheet, 8th graders solve 21 different problems to include identifying each number as prime, composite, or neither prime nor composite and listing all the primes less than 200. Then they complete each...

In this scientific investigation worksheet, students use "magic tubes" to make observations, hypothesize, study variables in experiments, write procedures, and draw conclusions.

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 this experimental design worksheet, students experiment with three coins, a dropper and water. They determine how many drops of water they can put on each coin. They answer questions about their experiment and they design an...

Music has been said to effect short term memory. Learners test out this hypothesis, graphing how knowledge retention in a biology classroom changes when music is played in the background. In the end, a better appreciation of the dynamics...

The artistic choices Art Spiegelman made in his graphic novel, Maus, are the focus of an exercise that asks class members to compare classic comic book forms with Spiegelman’s panels and frames. Directed to specific pages and guided by a...

Demonstrate for your earth scientists how plant pollen of the past has become part of sedimentary deposits, providing clues about ancient climates. Then give them simulated sediment layer samples to analyze for different types of paper...

Are serving sizes for different foods always appropriate for what you need? In this hands-on activity, learners work in groups to estimate what one serving size of various foods are, and then evaluate their hypotheses by measuring...

In this teacher-led demonstration, your young environmentalists will observe and record how different types of water pollutants look when they are combined. From here, individuals will develop a hypothesis on how the water can be...

Your eyes each work independently, so how do we only see one image? The quick hands-on experiment encourages young scientists to test their blind spots on each eye individually. After learning where the blind spot is and why it exists,...
