Third graders examine the non-standard method of measurement and compare it to the metric system of measurement. For this introductory module lesson, 3rd graders discover the scientific observation. Students also develop communication...

Students design and conduct an experiment to determine the effect of salinity and temperature changes in the movement of ocean currents. In this earth science lesson, students record observations and collect data. They share their...

Students study flavinoids and how they exist in the plant kingdom.  In this pigment lesson students complete a lab activity to see how flavinoids move in substances then record their observations.

Students investigate the hardness of different water samples using the conductivity meter. In this chemistry lesson, students build their own meter following specific procedures. They identify an unknown sample of water.

Middle schoolers create a dichotomous key. In this categorizing lesson, students create a dichotomous key for different types of cereal. Middle schoolers classify the cereal into groups such as flakes and cereal with holes. Students...

Here is a lesson that rocks! Young scientists choose a rock and list words that describe it. They estimate the mass of their rocks and rank them within a group. They measure their rocks for volume and write a story that somehow includes...

Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the...

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Sixth graders explore the water displacement method to determine the volume of solid objects such as rocks, nails, and marbles.

Students observe a model of the distribution of the earth's water and compare the relative volumes and percentages of types of water on earth.

Students discover plant chemical processes through three lab activities. Overheads, data sheets, and teaching procedures provided for the unit covering photosynthesis, respiration, and transpiration.

Ninth graders explore the relationship between heat and temperature. After performing experiments, 9th graders record their observations and discuss the results. They investigate the properties of heat and explore how energy possessed...

Fifth graders determine volume and density through their knowledge of mass, volume and density.

Students discover that density is considered a property and that cutting an object in half does not affect its density. They examine the densities of many common substances and make connections.

Students explore the Ring of Fire. In this volcano activity, students discuss active volcanoes in the world and explore viscosity as they participate in a hands-on classroom activity.

Students recognize the presence of organic matter in soils from their immediate area and recognize which soil sample contains the highest concentration of organic matter.

Pupils perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...

In these earth science worksheets student complete this project to model activity in the mantle, one Earth's four layers. The project includes liquid and powder materials in addition to several measuring components. Students must then...

Students have the opportunity to observe, measure and analyze the density of aerosol shaving creams and foams generated from shampoo and dishwashing liquids or detergents.

Students test for amaylase enzyme in a variety of substances. Student pairs perform a series of tests to determine how long it takes the starch sample to change to sugar molecules and the blue color to disappear when various saliva...

Students easure and record volume of water, then measure and record mass of soil. They explain the effects of the following in controlling erosion: Contouring, cover crop, strip cropping, reforestation, inter-seeding.

Pupils discuss sound and how it's measured, and through experimentation and implementation of the scientific method, they determine the speed of sound.

Students predict the appearance of a geode's internal structure based on its mass and density. They form a hypothesis based on the data they collect. They also identify common minerals found in Illinois.
