Learners develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.

Learners determine the best material from which to make a jacket to keep the body warm in a cold, dry, windy climate. This task assesses the student's abilities to perform an entire investigation.

Young scholars determine whether the index of refraction of sample of Corn Syrup meets Federal standards. This task assess students' abilities to explain the procedures for investigation, plan for recording and organizing observations...

Students investigate Newton's Laws of Motion and the Law of Conservation of Energy. They examine how a ball and half-ball behave and relate these laws to what happens to the ball. Students produce a graph of the data collected and...

Students design and conduct an experiment to determine which of three solutions contain starch or sugar. This task assess students' ability to make simple observations, design simple experiments, utilize indicators, and make generalized...

Students design and conduct an open-ended investigation using a variety of earth materials to answer a questions posed by the teacher: How does the erosion of sand compare with the erosion of gravel? After producing evidence that...

Eighth graders determine the presence of starch and sugar in unknown solutions. This task assesses students' abilities to observe, record and interpret data, classify, generalize/infer, construct data tables, and identify sugar and...

Students measure the rate of sinking of a test tube into a beaker of "glop", representing a model of the interaction between the Earth's crust and upper mantle. This task assesses students' abilities to make simple observations,...

Fifth graders are presented with three rocks and a variety of tools and are asked to investigate the properties of the rocks to see which rock is best for building tables and benches for a museum picnic area.

Students investigate and compare the bouncing ability of the materials from which four different balls are made. They determine which material performs the best for use as a basketball. After collecting data in a small group they...

Learners use a classification key from a provided worksheet to identify creatures. This task assesses student's abilities to interpret data, make decisions, identify, and classify.

Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.

Eighth graders determine the amount of agitation necessary to dissolve various sized sugar particles. This task assess students' abilities to collect, organize, and interpret data, create appropriate graphs, predict future events based...

Eighth graders investigate what would happen to the length of a rubber band as more and more rings were hung on it. They base their explanation on what they observed, and as they develop cognitive skills, they should be able to...

Learners shake a box containing Plaster of Paris "rocks", gravel, and sand, to measure the effects of erosion. They work individually during this exercise. This task assesses students' abilities to make simple observations, describe...

Students observe, measure, and graph a model of slow down slope movement representing soil creep. This task assesses students' abilities to collect, record, and organize data, set up graph axes, plot data points, draw line graphs, apply...

Students place a peat pot in water to observe and calculate the rate of capillarity in a model of a soil. This task assesses students' abilities to make simple observations, collect, record, and represent data, use a data table to...

Students determine which of several soil samples (sand, soil, and slit) produces puddles, providing insight into the permeability of these different soils. This task assesses students' abilities to make simple observations, collect,...

Eighth graders use a measuring stick to determine the shape of the inside of the bottom of a box, then apply their knowledge to an additional situation. This task assesses students' abilities to make simple observations, collect and...

Students measure the mass, volume, length and area of various objects. They are assigned a letter. The task is assesses students' abilities to make simple observations and measurements.

Students investigate circular motion in two different activities. In the first, students observe the path of a rolling marble on a paper plate. In the second, students play a game of catch using a tennis ball inside a plastic bag. ...

Learners perform an experiment, collect, and analyze data of a rolling marble down a ramp. They report results after they complete their experiment. Students are assessed in science and writing.

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...

Pupils use one of four absorbent products to separate as much of the oil and water mixture they are able to do. The purpose of this task is for students to collect and analyze data for the purpose of determining which absorbent is best,...
