Students act as paleontologists to discover who a mystery guest to the classroom was. They do not know the identity of the guest but infer the identity from items left behind in the classroom. They make inferences from dinosaur fossils.

Students explore reasons why the dinosaurs became extinct, and the specific needs (habitat, environment, food) of individual types of dinosaurs.

High schoolers complete a unit focusing on the creation of a student-generated website. They read and evaluate articles about business ethics, critique websites, and develop a student-created webpage.

Students participate in activities in which they model different disabilities. They discuss their experiences as a class. They work together in groups to discuss how to improve an adaptive device.

Students examine the materials that are used to make space suits. They complete an experiment in which they test different materials in different colors to determine the best one for keeping astronauts comfortable. They analyze the data.

Students measure oxygen percentages in room air and air exhaled after they perform various activities. They explore various websites, and record and analyze the data from the experiments.

Seventh graders determine the amount of blue food coloring in sports drinks and plot the concentration and absorbance data. They summarize the data and determine why companies need to know the amount of chemicals in their products.

Students compile statistics from high school or other football team and construct a spreadsheet on which to record their findings. Using Chart Wizard to analyze the data, they construct charts and graphs for a visual display of the...

Students investigate how Global Positioning Systems work and how and why GPS receivers make errors. They graph data points and apply estimation and prediction to real-life GPS situations, discuss time delay, and complete a worksheet.

Students investigate several unidentified substances and suggest a use of each substance. They can explain that a substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of...

Fourth graders construct a model of Indiana which displays the effects of the glacial period on the state's physical structure. Students work in groups to plan and execute their model based on an established rubric.

Seventh graders investigate the strength of the muscular system. They explore voluntary and involuntary muscle movement and discuss the types of muscles: cardiac or heart, skeletal, and smooth. They visit stations to answer questions...

First graders study number pairs and identify number pairs that sum to numbers from 10 to 30. They use number pairs to solve addition and subtraction problems. They make sensible estimates and check the reasonableness of answers.

Third graders use mental-math strategies to solve two-digit plus two-digit addition problems. They observe and discuss online demonstrations, solve word problems as a class, and independently solve problems and describe their solutions...

Third graders study the meaning of the digits an any whole numbers with up to 3 decimal places. They order decimals with up to 3 decimal places and perform measuring tasks, using a range of units and scales.

Second graders study digits in 2- or 3-digit whole numbers. They write and solve story problems which involve whole numbers, using addition, subtraction, multiplication, or division.

his unit uses two of the series of four Divider learning objects to support the students division of whole numbers where the quotient is a mixed number (whole number and fraction). The Divider encourages the students to split a division...

Students observe diffusion of glucose through a cell membrane and research the function of chromium picolinate in glucose uptake into a cell. They conclude and understand the role of insulin and chromium picolinate in the uptake of...

Third graders write a number in their journals that the teacher dictates. They use place value tents to make the number and write it in expanded form. Next, they repeat the process before making numbers that are more or less than the...

Third graders, given the price of different ingredients, make a trail mix of five different items without exceeding their budget of five dollars. They choose between pretzels, M&M's, twizzlers, popcorn, etc,. Each student practices...

Fifth graders study the processes of erosion, transportation, and deposition in soil. They walk outside the school to see examples and then accurately create a physical model which shows each type of soil movement and allows them to...

Students examine some of the different ecosystems that fish live in. While doing this they identify the species of fish and the ecological conditions needed for survival. Students use research resources to make fish cards that have...

Students examine macro-invertebrates in order to better understand their link to the food web. Working in groups, they record observations of several areas of a stream or river, collect samples from the river bottom, and identify the...
