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
Density of Minerals
Learners determine the mass, volume, and density of two different mineral samples. Students show data and calculations as well as answer questions about the mineral identities.
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.
Curated OER
Pendulum
Sixth graders are instructed on how to create a pendulum and measure the periodicity of the pendulum, using four different combinations of string. They are asked which influences the time more- the length of the string or the weight at...
Curated OER
Sound Box
Students make simple observations and identify relevant variables, such as frequency and diameter. They then discuss the relationship between variables. The task assesses students' abilities to make simple observations and make...
Curated OER
Threads
Students group observed data, filtering from all their observations the similarities between burring threads. In the second part they make a comparison of a chosen attribute between the two threads.
Curated OER
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...

Learners 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. Learners 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
Identifying Elements
Young scholars use diffraction glasses to find similarities and differences between observed spectrum of fluorescent light and an incandescent light They work in groups of 4-6 for the experiment/activity part of this exercise.
Curated OER
Dichotomous Key
Eighth graders use a dichotomous key to identify unknown fictitious organisms. They work individually during this exercise. The task is designed to take students approximately 15-25 minutes to complete.
