How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Simulate soil sample assemblages. Individuals create soil layers in a cup. They then use straws to collect core samples from these layers. What information can they glean from the core samples, I wonder?

Students observe and explain how a change in temperature causes a physical change in a substance.  For this physical science lesson, students use a soap making kit to observe the effects of adding heat to the bar soap as they...

Young scholars investigate common household items and classify them into types of matter. In this matter lesson, students group given items into categories based on their characteristics. They also complete a concept map about matter and...

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...

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

Third graders discovver what causes the dramatic colors of a sunset by seeing the changing color of light as it passes through a clear container of water to which milk is gradually added. They measure the liquids and observe what happens...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

First graders observe examples of the three states of matter and identify matter in each of the three states. They make glitter wands to remind them of the three states of matter: solid, liquid and gas. Pupils brainstorm and record...

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

For this identifying the weather terms activity, students read phrases about the weather and choose the term being described. Students choose 11 multiple choice answers.

Sixth graders investigate the various types of pollutants found in water and ways to help prevent water pollution. Through a hands-on experiment, students create samples of polluted water by mixing water with vegetable oil, dirt,...

With rising oil prices and increasing concerns over global warming, the pressure is on for engineers to develop alternative sources of energy. Among the new technologies being developed are hydrogen fuel cells, which young scientists...

Hate to vacuum, but enjoy using a vacuum pump? Explore a instructional activity that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor...

Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Students complete activities where they observe the amount of freshwater in the world as a fraction of the actual amount of water using different mixtures. In this freshwater lesson plan, students brainstorm on how to preserve...

If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

In this How Does the Heart Work worksheet, students write a short explanation of how the heart works based on 7 phrases given. Students also participate in 2 extension activities.

What is the difference between a comet and a meteoroid? An educational lesson includes five demonstrations of how the atmosphere can inhibit our ability to measure many things in the galaxy. 

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.
