Students perform tests in the lab to identify an unknown substance. For this physical science lesson, students observe the physical and chemical properties of substances. They formulate a conclusion based on experimental results.

Students measure angles of refraction as the light travels through gelatin.  In this experimental lesson students complete a refraction lab and plot their data.

Students observe seeds growth and examine the different parts of the seedling. In this biology lesson, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...

Learners conduct a series of scientific investigation using bioinformatics. In this molecular biology instructional activity, students collect experimental data using different educational softwares. They calculate and analyze...

In this project learning exercise, learners complete a formal write up of their experiments. This includes a rationale, a purpose, a hypothesis, their experimental design, materials, procedure, data tables with variables, graphs and a...

In this hypothesis and title writing worksheet, students are given five experimental questions and they are to write an appropriate title and hypothesis for each question.

In this weathering, erosion and deposition worksheet, students answer questions about the causes of weathering, the types of weathering such as mechanical and chemical weathering and resistance to weathering. They also write two...

In this experimental design worksheet, students fill out their title, hypothesis, independent and dependent variables, data table, graph and conclusion for their lab.

The history of aerodynamics is rich with experimentation and international collaboration. Author Joyce Bryant relays this dynamic past and provides math word problems using the formula of lift, the force that makes airplanes fly. She...

Let's heat things up! This simple experiment demonstrates for students the important role the sun plays in providing the earth with energy. Place one cup of water in direct sunlight and one in shade, then take measurements in order to...

A professional-quality PowerPoint, which includes links to footage of actual landslides in action, opens this moving lesson. Viewers learn what conditions lead to erosion and land giving way. They simulate landslides with a variety of...

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

Learners describe the roles of controlled, manipulated and responding variables in scientific research. They also identify biotic and abiotic interactions affecting the makeup of a plant community.

Young scholars identify the physical needs of animals and if plants need the same things as animals. They conduct an experiment to see if plants need light and water to grow. They compare the growth of the plants exposed to the...

Learners experiment with several chaotic simulation, they build a working definition of chaos. Students reinforce their knowledge of basic probability and percents. They are reminded of previous knowledge that is pertinent to this...

Students are introduced to Scientific Inquiry and discover how to design an experiment that answers critical questions using butterflies as the topic. They design experiments that compare the number of species of butterflies in a vacant,...

Students explore the living conditions needed to grow bacteria. They develop an experiment that will test the ability of bacteria to survive various temperature extremes. In addition, they complete a lab reprt to share their results.

In this science worksheet, students look for the words that are related to the theme of the worksheet. They also work on the skills of spelling and word recognition.

Twelfth graders look at local speed limits and traffic controls and see if they are reasonable. They plot the displacement and time to represent velocity, develop a plan for improving the current system, and organize experimental...

Young scholars examine the scientific method and lab procedures. They solve problems using experimentation, observation, and the scientific method.

Eighth graders use colored candy pieces (such as M & M's) to compare mathematical expectations and experimental probability. They pick pieces of candy randomly, and graph their results. This classic lesson never fails to engage...

Fifth graders collect and organize data from writing samples, use fractions and decimals to describe the experimental data, and use the experimental results to make predictions about the frequency of letter usage in the English language.

Students meet NASA researchers who describe the relationship between force, energy and motion. They discuss how NASA's experimental X-plane is being tested to make space travel more reliable and show how proportionality and ratios are...
