Students' recognize the various roles of predicting in science. Students' practice making and interpreting predictions; experimenting to test their hypotheses; and refine their predictions based on observation and experimentation....

High schoolers take a stand on a hypothesis for U.S. entry into World War I, supported by specific evidence.

Learners define the term species, and graph species data together with previously collected data at the National Zoo. They interpret graphed data and recognize patterns in the streamside quadrant versus hillside quadrant. Students use...

Students compare facts about different countries. In this comparing instructional activity, students collect information about the US and another country and compare them. Students locate countries on the map and make a hypothesis about...

Young scholars inspect a given problem and come up with a hypothesis. In this investigative lesson students come up with a hypothesis for a problem, test each hypothesis and evaluate how successful each one was. 

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.

In this solving problems instructional activity, students answer twelve multiple choice questions about problem solving in science and the steps of the scientific method. These include identifying the problem, forming a hypothesis and...

Students identify and apply the scientific method through an experiment with popcorn. Then they identify what independent, dependent, and control variables are and create a list of different variables that affect popcorn popping....

Learners role play scientists to prove a hypotheses. They determine whether or not walruses stay warmer in water or in air. Students also determine in which environment they lose more body heat.

Being able to test a hypothesis is a scientific must. AP Biology pupils can see the process of hypothesis testing through evidence for evolution as seen in natural selection. Slides contain solid information and excerpts from academic...

How does the scientific process begin? Introduce ecology scholars to scientific inquiry through an insightful, data-driven lesson. Partners examine data from an ongoing research study to determine the questions it answers. The resource...

Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...

Conduct an experiment to determine the accuracy of pedometers versus pedometer apps. Class members collect data from each device, analyze the data using a hypothesis test, and determine if there is a significant difference...

Middle school scientists learn the steps of the scientific method by watching this phenomenal film and by singing a karaoke song! They are introduced to making observations and hypotheses, determining variables, data collection, and...

Make pathogens and the body's defense systems come alive for young biologists in a hands-on activity. Investigators model the skin's protection against infection by observing and comparing changes in a punctured tomato and an intact...

Middle schoolers investigate methods of pollination for various flowers. In this plant biology lesson, students learn the parts of a flower and form a hypothesis about the method of pollination for the flower. They determine the...

Feeling under the weather? This lesson on hurricanes can whip things up! With professionally designed maps and handouts, teach your future weathermen (or women) where, when, and how hurricanes occur. They identify hurricane regions and...

Students observe a scientific experiment and pose a hypothesis. In this scientific inquiry lesson, students make predictions about the combination of alcohol in water and how it will affect a floating ice cube.

In this writing conclusions activity, students practice writing and evaluating paragraphs written at the end of an experiment. They are given a hypothesis and a results sentence and they write a conclusion.

This slide show provides an opportunity of you and your class to plan your own scientific investigation. Each slide contains one part of the scientific hypothesis-building process and a space to type in what the class chooses to focus...

Students observe obscertainers through indirect observations and make hypotheses about the internal wall structures of the containers. In this indirect observation lesson plan, students make observations of 4 obscertainers with a steel...

Students conduct an experiment.  In this marine debris and environment protection instructional activity, students categorize trash into piles, predict whether these trash items will sink, float or be picked up and carried by the...

In this problem-solving worksheet, students will read a biologist's observations about elephant communication. Students will write down what the biologist observed, what facts she knew about elephants, and her hypothesis. Students will...
