Fourth graders use this lesson to focus on their health, nutrition and the state of the environment. In groups, they examine the various types of land, water and air pollutants and compare and contrast a food chain with and without a...

For this acid and base worksheet, students test 13 different substances to determine their pH, the type of acid or base they are, the color the universal indicator turns, the color red litmus paper turns, and the color blue litmus paper...

In this minerals worksheet, students answer fifteen multiple choice questions about mineral formation, volcano and mountain formation, mineral tests and properties of minerals.

Students weigh various battings and feathers. They make sure to have the same weight of each type of insulations. Students wrap one bottle of warm water in each of the two insulations. They measure the temperature of each bottle,...

Save the soup! Scholars devise a flotation device using straws, balloons, foam, corks, and other objects. A can of soup must stay afloat for at least a minute with this device—your dinner might depend on it!

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Provide high schoolers with their own indoor gardens! Emerging scientists discuss the process of photosynthesis and germinate seeds before growing plants in multiple lighting conditions. The hands-on application allows...

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

Germs, parasites, and viruses, oh my! Facilitate a lesson on viruses as individuals explore functions of Archaea, Bacteria, and Eukarya. They learn how viruses compare with other organisms in nature and how they contribute to health...

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

Students study the differences between an acid and a base.  In this pH lesson students view a demonstration then test chemicals in groups.

Students perform soil tests for pH, nitrogen, phosphorus, potassium, composition and water percolation rate and assess the conditions in the schoolyard.

Tenth graders discuss marine mammal diving reflex, and measure pulse rate while holding their breath under three conditions: control, warm water, and ice water to determine if humans exhibit marine mammal diving reflex.

Students formulate hypotheses on wave behavior and test them. For this physics lesson, students compare and contrast transverse and compression waves. They determine the wavelength of transverse waves.

Fourth graders perform an experiment to test the function of a stem. In this science lesson, 4th graders write a description of their investigations. Students also explain how the stem interacts with the rest of the plant. Students use...

Students explain how a feedback control system works. They model a feedback control mechanism for controlling water level by observing the flow rate of water in a cylinder. In addition, they graph their data. Script for lesson is included.

Young scholars conduct an experiment. They review how to use the scientific method to conduct an experiment with white carnations and food coloring. They create a hypothesis and test it to better understand how plants get nutrients,...

Young scholars swab different sections of the tongue to identify taste buds. In this sense of taste lesson, students make predictions and conduct an experiment. Young scholars experiment with a variety of flavors and discuss...

Explore the history of cholera and its effect on society with your biology class. Young biologists will then proceed to grow their own germs, prepared from live cultures, and follow the steps of the scientific method to generate data....

Have your young scientists questioned why plants grow a particular way? Through this learning opportunity, scientists gain firsthand knowledge about how plants develop and various factors that affect rates of growth as they bring plants...

Do polar opposites attract? After an introduction on the polarity of molecules, pupils are asked to design a self-assembling model using materials with different polarity. The challenge should motivate learners to develop a workable...

How can you relate colligative properties of solutions to everyday situations? Pupils first discuss the concepts of density, boiling and freezing points, then demonstrate how to accurately determine the boiling and freezing point of...

Finally, a chance for the class to play with their food! Allow pupils to simulate stomach acid with common foods, and introduce specific macromolecules into the mixture to explore characteristics of carbohydrates, lipids,...

After nine lessons and activities about energy, here is the final assessment. The 20-questions include multiple choice, multiple choice with justification, short answer, answer analysis, and labeling diagrams to challenge learners.
