Curated OER
More Power to You
Pupils construct a simple galvanometer in order to detect the presence of an electric current as well as determine the amount of the current. Activity is divided into two parts, first part as group work and second as individual.
Curated OER
Changing Ramp Heights
Learners conduct an experiment to determine how the change in ramp height affects the distances a ball is able to move a stationary cup. Data is collected from several trials and recorded and analyzed.
Curated OER
Circular Motion
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. ...
Curated OER
Swinging
Students examine and modify a swinging apparatus. They describe the motion of an object by its position, direction of motion, and speed. Students measure motion using a graph.
Curated OER
Height of Bounce
Eighth graders determine the relationship between the height of bounce of a ping-pong ball and the height from which it was dropped. They are assessed on the ability to record and interpret data, graph data, make predictions, and make...
Curated OER
Rolling Down Hill
Students 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.

Pupils use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Pupils use...
Curated OER
Powder
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...
Curated OER
Changes in Pulse Rate
Eighth graders practice making observations and collecting data after determining a baseline pulse rate then collect data on the changes in that rate with exercise. Students must organize their data and analyze their observations.
Curated OER

Formation of Wind
Young scholars correctly sequence the steps leading to the formation of wind, and describe the cause and effect relationships involved in the formation of wind. This task assesses students' abilities to classify, generalize, infer,...
Curated OER
Water Pollution
Students study four samples of "rain water". They asked to determine the pH of the samples and then to neutralize them. Students are asked to predict any negative effects which might be associated with water having a low pH and to...
Curated OER
Soap, Wood, and Water
Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.
