What is a scientific investigation? What are the various parts of an experiment? This worksheet provides a basic review of most key terms: scientific method, manipulated variable, responding variable, hypothesis, controlled variable,...

Students investigate hot melt glue using a hot melt glue gun as an an injection molding simulator and a melt index viscometer. They evaluate the effect of heating and cooling by weighing the glue extruded over a constant time period.

A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

Lead your class on a journey to the planet Jupiter and provide them with fun facts in the process. Learners explore radio waves emitted by Jupiter to further understand how this data helps our daily lives. They conclude by discussing...

While this lesson is based on the Bruchid beetle, the focus is on conducting a scientific investigation. Ecology explorers vary the temperature or the type of leaf that Bruchid eggs are laid on and test for effects on the development...

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...

Young scholars compare the perceived and actual risks of getting skin cancer, while looking at ways to minimize these risks. They may have very little grasp of the severity of the threat of skin cancer or be unaware of the increase in...

You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

Students participate in a three-part lab in which they investigate plant pigments. Part I is designed to teach basic laboratory techniques of column chromatography, in Part II students design an experiment to separate the components of a...

Don't melt away! Pairs investigate different insulation materials to determine which one is better than the others. Using a low-temp heat plate, the teams insulate an ice cube from the heat source with a variety of substances. They...

Wave goodbye to the same old demonstrations for alternative energy sources, and wave hello to this one investigating ocean waves! Using a water bottle to create an oscillating water column, learners see and possibly hear how the...

Students explore detective investigations. In this introduction to mysteries lesson, students role play eye witnesses and investigators related to a "crime" committed in their classroom. Students collect evidence and record information,...

This series of investigations lead students to have a greater understanding of the pumpkin and give them a chance to experience scientific study.

Students study chemistry.  In this laboratory lesson students watch the CSI episodes and investigate their laboratory techniques and discuss what they saw.

In this geology worksheet, students investigate a sample piece of granite and describe the properties of granite in a 15 question chart.

Investigate the prospect of wind as a renewable resource. Second and third graders make a pinwheel, answer critical thinking questions, and then attempt to use wind power to wind string. I would be more apt to use this lesson in a 1st or...

In this investigations activity, students complete a hypothesis, variable manipulation, and more for sleeping habits, rolling wheels on a skate board, sports practice, and more.

An internet investigation leads learners to discover whether or not weather and light house location are related to the locations of shipwrecks on The Great Lakes. They work in cooperative groups to plot the locations of light houses and...

An evaporation investigation! This collection of slides walks future scientists through the process of setting up an experiment on how to speed up evaporation. The experiment is simple enough to use at the beginning of the school...

Play "Would You Rather" with your physical science class as an anticipatory set. Each game question is related to the pressure put on an area of the body. Let this activate a discussion on forces, pressure, and area. Give your class...

Define the scientific concept of absorbency as it relates to the properties of matter, then conduct an investigation. Learners answer several questions, then investigate the absorbency of several different types of towels. Tip:...

Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Students review data about a health problem and prepare an investigative report. Teams trade reports and utilize skills developed from previous lessons to evaluate the critical thinking evident in the reports.
