Repeated motion is present everywhere in nature. Learn how to 'make waves' with your own movements using a motion detector to plot your position as a function of time, and try to duplicate wave patterns presented in the activity. Investigate the concept of distance versus time graphs and see how your own movement can be represented on a graph.

This activity is an extension activity following a unit study on mixtures and solution. Students will use variables to create a unique cola formula and present their findings.

This Chemistry experiment investigates physical changes, solutions, supersaturated solutions, and states of matter.

This task requires students to study the make-a-ten strategy that they should already know and use intuitively. In this strategy, knowledge of which sums make a ten, together with some of the properties of addition and subtraction, are used to evaluate sums which are larger than 10.

This task is to introduce students to the concept of reading an analog clock.

Making a 10 provides a technique to help students master single digit addition. The task is designed to help students visualize where the 10's are on a single digit addition table and explain why this is so. This knowledge can then be used to help them learn the addition table.

The purpose of this task is to generate a classroom discussion about ratios and unit rates in context.

Spreadsheets Across the Curriculum Module. Students build spreadsheets to estimate discharge for a culvert using the Manning equation, and to estimate culvert size, given a specified discharge.

Historically, seafloor mapping occurred with a simple data collection method: soundings. Soundings are taken by dropping a weight with a pre-measured rope off the side of a boat and noting the measurement on the rope when the weight hits the bottom. In this activity, student teams replicate the creation of seafloor bathymetry by taking a simplified form of soundings of an unseen seafloor model inside a shoebox and translating their collected data into a visualization of the topography, enabling them to better understand and appreciate modern remote sensing.

Students are introduced to the concept of tracking and spatial movements of animals in relation to the environments in which they live. Students improve their understanding of animal tracking and how technology is used in this process.

Spreadsheets Across the Curriculum/Geology of National Parks module. Students work with a color-coded conditional-formatted spreadsheet map to work through a USGS report applying a coastal vulnerability index, examining real data related to relative sea-level change for different areas of the Californian coas,t including Point Reyes National Seashore.

This activity is an investigative introduction to mapping. Students create maps and determine important map features.

This activity is a classroom investigation where students test the impact track shape has on vertical distance of a rolling object.

In this problem, students consider the benefits of reduced tray usage in school cafeterias by comparing the cost savings of having to clean fewer trays against the opportunity cost of increased labor and energy costs to clean the cafeteria after meals.

This task provides three types of comparison problems: Those with an unknown difference and two known numbers; those with a known difference and a bigger unknown number; and those with a known difference and smaller unknown number. Students may solve each type using addition or subtraction, although the language in specific problems tends to favor one approach over another.

The marine environment is unique and because little light penetrates under water, technologies that use sound are required to gather information. The seafloor is characterized using underwater sound and acoustical systems. Current technological innovations enable scientists to further understand and apply information about animal locations and habitat. Remote sensing and exploration with underwater vehicles enables researchers to map and understand the sea floor. Similar technologies also aid in animal tracking, a method used within science and commercial industries. Through inquiry-based learning techniques, students learn the importance of habitat mapping and animal tracking.

This activity will take complex molecules and polyatomic ions the students have learned and construct them out of marshmallows and redhots. This develops understanding in VESPR structures and hybrid molecules.

This lesson is a classroom activity where students learn about paleontologist Mary Anning, briefly learn about sedimentary rock, and complete observation drawings of Platteville Limestone fossils.

Spreadsheets Across the Curriculum module. Students build spreadsheets to find the maximum volume of an open-top box by cut-and-folding a sheet of cardboard.

This is an indoor lab that uses a boat simulation to demonstrate the concepts of mass, volume and density, and their relationship to displacement. It is a problem solving activity that encourages student creativity resulting in a variety of valid solutions.
