Students develop simple observations. They observe bleeding of colored inks with water, to understand mixtures, and to make generalized inferences from their observations.

Students view a video on bridges and domes. They discuss the importance of shapes, especially triangles for these structures. They participate in an activity in which they create their own dome out of paper clips.

Students participate in an interactive writing and discussion activity, on the study of bias, as it is used in political debate and decision making. They evaluate the presentation of material and its importance in making informed decisions.

Students solve systems of equation through graphing. For this algebra lesson, students solve linear equations and analyze the result to figure out if there is one solution, no solution or infinitely many solutions. They graph their lines...

Learners perform an experiment with different types of bird eggs to determine what factors make them strong and able to stay on a cliff without rolling off.

Students explore magnetism. They make observations of everyday items regarding their magnetic attraction and use their experiences to make a prediction.

Use this worksheet with the Hands-On Equations kit of manipulatives. Learners find the value of x in 5 equations, then check their answers. A great addition to your math lesson!

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...

Students explore and identify the power of national and state governments. They discuss the concept of federalism and the distribution of governmental powers. As a class, they examine the balance of power between the federal and state...

Students consider modern applications to the Bill Of Rights (how does Ammendment 4 apply to locker searches?) students prepare and role play a mock trial to explore the finer points of the relevance ot the Bill of Rights in the 21st...

Learners investigate the Founders' ideas about what kind of government is most likely to protect the basic rights of people. They distinguish between limited and unlimited government.

Students read a document which explains the roles and responsibilities of the President of the United States. In groups, they tour the George Bush Presidential Museum and participate in a Presidential scavenger hunt. Once back in the...

Students spend the duration of this lesson examining the text of the Endangered Species Act. Individually, they complete a profile to determine where they stand on the bill and read excerpts from it. Some role-play the various members...

Students, in groups, estimate and check the weights of classroom objects using coins as the standard of measure.

Students engage in a lesson on how to use an ATM, or Automated Teller Machine. They see how to bank with an ATM and practice banking using several different types of transactions. This lesson includes a teaching worksheet to practice...

Students examine space food. In this space science instructional activity, students visit suggested websites to identify the eight categories of space food. Students use a space food nutrition guide to classify space food.

High schoolers investigate the concept of paying bills by writing checks. They practice writing a check with the specific elements filled out correctly and then record the amount of it in the check register. Students also extend the...

Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.

Students investigate the lever and the mathematics associated with levers. They determine the conditions necessary to balance a system of forces around a fulcrum.

Fourth graders rank balls by size from smallest to largest and from lightest to heaviest and then by how much they made the water rise. They then discuss why certain balls make the water rise higher than do other balls.

Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.

Students discuss the meaning of balance and how it applies to equations. After listening to a lecture, they practice solving equations with two orders of operation and doing whatever they do on one side to the other side as a class. To...

Pupils solve and graph linear equations. In this algebra lesson, students solve systems of equations using elimination and substitution. They graph their answer and identify the point of intersection.

Students compare the price and quality of different kinds of plastic kitchen wraps and then rank them from best to worst. They take into account how well it comes out of the roll, if it seals well, it is tangles, how much weight it...
