Before entering first grade, young children need to have a basic understanding of measurement. They do not need to be able to use standard units of measurement, but they must be able to use the basic attributes of length.

In this lesson and its associated activity, students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. The three liquids are water, rubbing alcohol, and vegetable oil; because of their different surface tensions, more water can be piled on top of a penny than either of the other two liquids. However, this is not the main point of the activity. Instead, students are asked to come up with an explanation for their observations about the different amounts of liquids a penny can hold. In other words, they are asked to make hypotheses that explain their observations, and because middle school students are not likely to have prior knowledge of the property of surface tension, their hypotheses are not likely to include this idea. Then they are asked to come up with ways to test their hypotheses, although they do not need to actually test their hypotheses. The important points for students to realize are that 1) the tests they devise must fit their hypotheses, and 2) the hypotheses they come up with must be testable in order to be useful.

Students investigate how mountains are formed. Concepts include the composition and structure of the Earth's tectonic plates and tectonic plate boundaries, with an emphasis on plate convergence as it relates to mountain formation. Students learn that geotechnical engineers design technologies to measure movement of tectonic plates and mountain formation, as well as design to alter the mountain environment to create safe and dependable roadways and tunnels.

Most of the flavoring in gum is due to the sugar or other sweetener it contains. As gum is chewed, the sugar dissolves and is swallowed. After a piece of gum loses its flavor, it can be left to dry at room temperature and then the difference between its initial (unchewed) mass and its chewed mass can be used to calculate the percentage of sugar in the gum. This demonstration experiment is used to generate new questions about gums and their ingredients, and students can then design and execute new experiments based on their own questions.

Kindergartners measure each other's height using large building blocks, then visit a 2nd and a 4th grade class to measure those students. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, how height changes as children get older. The introduction to graphing provides an important foundation for both creating and interpreting graphs in future years.

Why is it important to listen to your feelings when using technology? This foundational digital citizenship lesson challenges kids to pay attention to their feelings while using tech. With an engaging emoji game, students learn practical strategies for managing their feelings -- good, bad, and everything in between. Approximately 30 mins.

LESSON OBJECTIVES: Recognize the different kinds of feelings they can have when using technology. Know what to do when they don't have a good feeling when using technology.

At what age should people be allowed to use social media? Children have to be at least 13 to sign up for most social media platforms. But we know that many tweens work around this restriction. By doing so they can connect with peers and have fun, but they're also susceptible to a number of risks, from privacy to bullying to challenges to their social-emotional well-being. Reflecting on when kids should be allowed to use social media can help us think through the risks and rewards of using social media, regardless of our age. Approximately 45 mins.

LESSON OBJECTIVES: Explain why websites that collect personal information have an age requirement of 13 in the United States. Identify the risks of targeted advertising, especially when it is targeted to children. Use the Take a Stand thinking routine to explore different perspectives about what age is best for starting to use social media.

Through four lessons and four hands-on associated activities, this unit provides a way to teach the overarching concept of energy as it relates to both kinetic and potential energy. Within these topics, students are exposed to gravitational potential, spring potential, the Carnot engine, temperature scales and simple magnets. During the module, students apply these scientific concepts to solve the following engineering challenge: "The rising price of gasoline has many effects on the US economy and the environment. You have been contracted by an engineering firm to help design a physical energy storage system for a new hybrid vehicle for Nissan. How would you go about solving this problem? What information would you consider to be important to know? You will create a small prototype of your design idea and make a sales pitch to Nissan at the end of the unit." This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn. This module is written for a first-year algebra-based physics class, though it could easily be modified for conceptual physics.

This student version of an economics lesson plan focuses on allocation. For a lesson about how the rule of force motivates, check out this informative website.

Students examine how the power output of a photovoltaic (PV) solar panel is affected by temperature changes. Using a 100-watt lamp and a small PV panel connected to a digital multimeter, teams vary the temperature of the panel and record the resulting voltage output. They plot the panel's power output and calculate the panel's temperature coefficient.

Learn about metamorphic, igneous, and sedimentary rocks and see many examples of each type.

Students use their knowledge equivalent fractions and their ability to compare fractions to play this computer based game.

Numerator values can be set for 0-20. Denominator values restricted to 1, 2, 4, 5, 8, 10 and 20. Use this interactive tool to show a fraction. Adjust both the denominator and numerator and see a visual representation as a part of a circle, rectangle or a set. Also, you can see the equivalent decimal and percent for each fraction.

Try this hands-on approach to solving algebra problems with this interactive website. Students are able to "solve equations, substitute in variable expressions, expand, and factor".

This task asks students to identify which of the six polygons have the same area. Students may complete the task using a variety of techniques including decomposing shapes, using transformations (rotations, reflections, translations) to move one or more parts of the figure to another part to more easily calculate the area, enclosing the polygon inside a larger rectangle and then subtract the areas of the "extra" pieces, etc.

The lesson provides an opportunity for students to not only read and view the importance of choosing career choices now, but gives them an opportunity to write about their future career goals and think about the best way to achieve them starting now.

In this inspirational biography unit, students read and learn about a diverse assortment of artists, musicians, and dancers, while focusing on identifying evidence from texts and illustrations.
