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

Students identify the factors affecting friction. In this physics lesson, students construct their own rocket car and race them. They graph the average speeds and discuss how lubricants affect friction between rubbing surfaces.

Students examine the new categories of planets and how planets were reclassified.  In this solar system lesson students complete activities using Venn diagrams and images of planets. 

Students examine how variations in temperature are due to the Sun and length of day.  In this solar lesson students complete a lab activity using thermometers and artificial sunlight to see how the earth is heated.

High schoolers research different city departments and organizations that make up a city and choose a type of house to model. In this construction lesson students build their own city and present it to the class.

Young scholars distinguish between scientific and everyday meanings of key words-theory, hypothesis, law, fact-and use in context. They recognize the variables that affect observation, data collection, and interpretation. They discover...

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

For this London Bombing worksheet, students read the article, answer true and false questions, complete synonym matching, complete phrase matching, complete a gap fill, answer short answer questions, answer discussion questions, write,...

In this experimental design and measurement worksheet, students answer questions about independent and dependent variables, they write hypotheses, they identify instruments that measure mass, weight, and volume and they calculate the...

Here is a instructional activity 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...

In this women's firsts worksheet, students complete a set of 10 multiple choice questions, choosing the correct woman who accomplished a given "first." A reference web site is given for additional activities.

Second graders explore the geologic process of fossil formation. In this geology activity, 2nd graders discuss the job of a paleontologist and make their own model of a fossil. This activity includes teacher directed questions.

Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur.  In this matter activity students divide into groups and complete a lab experiment. 

Third graders observe light energy. In this heat and energy lesson, 3rd graders will study the concept of light as a form of energy. Students will examine the different forms of light and the type of energy it produces.
