Students create arrangements of a melody and listen to recordings contrasting in style and genre.

Students brainstorm strategies to guide their listening as they describe and label music of different genres.

This is a challenging fraction comparison problem. The fractions for this task have been carefully chosen to encourage and reward different methods of comparison.

In this activity, students design an innovative human shelter that is inspired and informed by an animal structure. Each group is assigned an animal class, and they gather information about shelters used by the animals in that class. After researching the topic and brainstorming ideas, students build small prototypes (models) of the structures. Finally, they present their products, explaining what attribute of the animal structure influenced their design.

During the activity, students build a model of the Milky Way and understand the objects contained in the Milky Way. They also get an idea about the distances between these objects.

Students learn the function of the liver and how biomedical engineers can use liver regeneration to help people. Students test the effects of toxic chemicals on a beef liver by adding hydrogen peroxide to various liver and salt solutions. They observe, record and graph their results.

Students take a hands-on look at the design of bridge piers (columns). First they brainstorm types of loads that might affect a Colorado bridge. Then they determine the maximum possible load for that scenario, and calculate the cross-sectional area of a column designed to support that load. Choosing from clay, foam or marshmallows, they create model columns and test their calculations.

In this number line task students must treat the interval from 0 to 1 as a whole, partition the whole into the appropriate number of equal sized parts, and then locate the fraction(s).

This task can be implemented in a variety of ways. For a class with previous exposure to the incenter or angle bisectors, part (a) could be a quick exercise in geometric constructions,. Alternatively, this could be part of a full introduction to angle bisectors, culminating in a full proof that the three angle bisectors are concurrent, an essentially complete proof of which is found in the solution below.

In this instructional task students are given two inequalities, one as a formula and one in words, and a set of possible solutions. They have to decide which of the given numbers actually solve the inequalities.

The goal of this task is to have students appreciate how the different constants (P0, K, and r) influence the shape of the graph.

This problem introduces a logistic growth model in the concrete setting of estimating the population of the U.S. The model gives a surprisingly accurate estimate and this should be contrasted with linear and exponential models, studied in ``U.S. Population 1790-1860.'' This task requires students to interpret data presented.

In this activity students compare objects to see which is longer and heavier than the other.

In this task students figure out how to draw the longest line on a map of the United States without hitting a border. They use color and line plots to keep track of their results.

This task builds on studentsŐ prior knowledge and understanding of conditional probability, and introduces the concept of independence of events.

The Lumen Waymaker Writing Skills Lab contains eleven complete and customizable model units that integrate with the college LMS. Each unit includes text, videos, simulations, and other interactive activities to engage students with learning. Each unit in the platform also contains student self- checks and graded quizzes.

Lumen makes their product easy and accessible for both students and instructors. When getting started with each unit, students will receive a personalized study plan. Students are able to test prior knowledge and then engage with in the program with the concepts that each student needs to work on the most. The students have access with enriched OER course materials within the platform. This product also provides students with immediate feedback and opportunities to continue to practice. The product also contains Offline Content Access where students can read each of the chapters offline, like a textbook.

For instructors, this product contains many faculty resources such as PowerPoints and Question Banks. One helpful faculty resource in the platform is the ability to create emails that the students will receive when they are struggling to complete a unit. The emails appear to come from the instructor right when the student needs it most.

Two children act as the Moon and the Earth. By holding hands and spinning around they mimic the tidal locking of the Moon. They note that the Moon always keeps the same face towards Earth.

In this 30 to 45 minute activity, children (in teams of 4-5) experiment to create craters and learn about the landscape of the moon. The children make observations on how the size and mass, direction, and velocity of the projectile impacts the size and shape of the crater.

Why does the Moon not always look the same to us? Sometimes it is a big, bright, circle, but, other times, it is only a tiny sliver, if we can see it at all. The different shapes and sizes of the slivers of the Moon are referred to as its phases, and they change periodically over the course of a lunar month, which is twenty-eight days long. The phases are caused by the relative positions of the Earth, Sun, and Moon at different times during the month.
