High schoolers differentiate lines and angles using betweenness in this geometry lesson. They differentiate angles and lines using Cabri Jr. and analyze the data and make conjecture.

Students study reaction rates, what determines how fast a reaction happens and how the chemical changes occur.  In this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create a graph...

Young scholars observe the changes a class tree goes through as the seasons change and record observations in journals. They investigate changes in the weather, changes in the length of the day, and how that affects people. They create...

In this introduction to chemistry worksheet, students complete 48 problem solving and fill in the blank questions. They convert measurements from one unit to another.

For this decibel worksheet, students answer 19 questions about amplifiers, circuits and the power gains or losses in these electrical systems.

Eighth graders build a structure that is able to withstand a simulated earthquake. They research earthquakes, earthquake measurement, and society's preparation for and reaction to them. Pupils build models and present them to the...

Students investigate the basic parts of plant and that plants are living things which require water, air, light and nutrients for survival. They do this through a series of scientific experiements and multi-curricular hands-on activities.

In this length worksheet, learners read about the history of a meter. Students also answer 4 comprehension questions about the reading.

A comprehensive resource gets fourth grade physical scientists making observations about the period of a pendulum and then applying knowledge to a playground swing. Through seven different stations, they will record observations and...

Differentiate between temperature and thermal energy. Your class will build a thermometer using simple materials and develop their own scale for measuring temperature. Discuss with your class and consider why engineers need to understand...

Students study the concepts of weight and drag while making paper helicopters. They measure how adding more weight to the helicopter changes the time for the helicopter to fall to the ground. They apply what they examine to the work of...

Learners revisit midpoint and segments by graphing on the TI or computer. This activity can be done with pencil and paper, but is more interactive if it is done on a TI-navigator.

Students examine reasons for immigration to the United States in the 19th century. They role play as immigrants asked to write accounts of their immigrant experiences.

Young scholars design and build a working catapult or trebuchet to explore the concepts of force, motion, and distance.

Students hike a local mountain and examine its life zones. They measure various components at each zone and collect leaf litter at the sites. At the mountain top, students make descriptive observations and complete a handout about the...

Examine the role of the Securities Exchange Commission. Upper graders watch a short Bill Moyers video, analyze a political cartoon, complete a graphic organizer on the SEC, and develop SEC reform strategies to rebuild investor confidence.

Here is another in the interesting series of lessons that use the special State Quarters as a learning tool. This one uses the North Dakota State Quarter. During this activity, your class learns about the different patterns of erosion,...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

An engaging lesson which has elementary learners measure weight to the nearest pound and construct and interpret a bar graph! They measure length using non-standard units and determine area using square tiles. Pupils round their birth...

Students study different formats of data and determine the nitrogen dioxide concentrations.  In this seasons lesson students understand the different relationships that NO2 can have.

Students use data microsets of mean near-surface air temperature and tropospheric ozone residual averages to infer patterns. Students analyze changes in tropospheric ozone and then hypothesize about the consequences of these changes.

Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

Elapsed time is a skill developed by the single question that is the center of this activity. Fifth graders are asked to find out the time that is 2011 minutes after the beginning of 2011. This question addresses the standard that...

Looking for a real-world situation to practice converting units? In this problem, learners must change miles per gallon to liters per km (or vice versa) to determine which car gets better gas miileage. It is a relatively short problem,...
