Students experiment with graphing. In this graphing introduction lesson, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another estimation example with...

Sixth graders set up a pendulum experiment deciding which variable to manipulate (length of string or weight on the string). They create a hypothesis, collect necessary equipment, and write out each step of their experiment. They then...

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

Students graph data on fetal and infant mortality rates collected by the Centers for Disease Control and Prevention. They identify trends in the data and propose potential causes for the trends.

Learners develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.

Examine parts of an expression in this algebra lesson. Ninth graders identify the properties of the coefficient and their behavior to the graph. They graph the equation on a TI to see their results.

Through exploration of linear programming through graphs and equations of inequalities, young scholars relate linear programming to real life scenarios, such as business. Graphing and shading is also part of this exercise.

Watch as your class makes the transition from pupils to researchers! A well-designed instructional activity has scholars pick a solar wind characteristic to research. They then collect and analyze official data from the LANL...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

In this where do plants get their food worksheet, students design an experiment that will disprove the idea that plants obtain their food from soil. Students will set up their experiment and design a data table that will record data over...

Students identify the vertex and intercepts of a parabola. In this algebra lesson, students graph parabolas and factor quadratic equations. They perform transformation on the parabolas.

Ninth graders conduct experiments to determine what affects the rate of a pendulum's swing. Working in small groups, they identify an independent variable to study and create an experiment to test their hypothesis. When tests are...

In this experimental design worksheet, students are given two experimental scenarios to read. They answer questions about each including finding the hypothesis, the independent and dependent variables and controls. They design a graph...

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...

Sixth graders conduct an experiment to understand the Big Bang Theory.  In this Big Bang Theory lesson, 6th graders will observe a balloon with confetti popping to emulate and analyze information related tot he Big Bang theory....

Watch the excitement grow as learners experiment with homemade rockets. Pupils create their own rockets from a soda bottle and experiment with launch angles. They discover the launch angle has a significant effect on the distance the...

How high did the ball go? Engineering teams build a working pneumatic system that launches a ball into the air. The teams vary the amount of pressure and determine the accompanying height of the ball. An extension of building a device to...

Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...

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 determine the concentration of an unknown solution. This task assesses students' abilities to state hypothesis, develop procedures for investigation, plan for recording and organizing observations and data, collect data, create...

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...

How can heat power an engine? Scholars observe a heat engine working and control variables to determine the most efficient setup. They change the amount of heat input as well as the stroke length. Energy efficiency numbers prove the...

Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...
