5.1 Scientific and Engineering Practices Task Card Review

Jerome models the movement of the Earth around the Sun using foam balls. The balls he uses are each the same size. Jerome explains that the model is not entirely accurate because the ball that represents the Sun should be much larger. What science and engineering practice is Jerome using when he identifies the limitations of his model? 

• Developing and using models

• Testing the model with different materials
• Creating a new model
• Evaluating the accuracy of a model

Sasha designs a device that transforms mechanical energy into electrical energy. After building and testing the device, Sasha creates a presentation that explains how the device works. What science and engineering practice is Sasha using when she shares the presentation with the class?

• Designing and building
• Testing and analyzing
• Obtaining, evaluating and communicating information

Tim is conducting an experiment to find how quickly his pepper plant grows. Each day, he measures the height of the plant and records the measurement in a table. What science and engineering practice is Tim using when he records data in a table?

• Experimental design and control
• Data analysis and interpretation
• Hypothesis testing
• Interpreting, analyzing, and evaluating data

Simone is conducting an experiment to determine what color shirts get the hottest in the sun. She knows she will need digital thermometers to measure the temperatures of the shirts and a timer so that she knows to measure the temperatures every ten minutes. What science and engineering practice is Simone using when she determines what tools she will need?

• Planning and carrying out investigations
• Communicating results
• Formulating hypotheses
• Analyzing data

Abdul is redesigning his backyard. His criteria for the design is that it must have a vegetable garden and a chicken coop. The constraints for the project are the size of his yard and the cost to purchase the materials needed. What science and engineering practice is Abdul using when he determines the criteria and constraints

• Constructing and critiquing conclusions and explanations

• Conducting experiments
• Analyzing data
• Developing a hypothesis

• depends on various factors

Asia is conducting an experiment to determine the effects of fertilizer on grass growth. She plants grass seeds in two pots that are the same size. She applies fertilizer to only one of the pots. 

What is an example of a hypothesis Asia could write?

• The grass in both pots will grow at the same rate regardless of the presence of fertilizer.
• The grass in the pot with fertilizer will die due to the chemicals in the fertilizer.
• If fertilizer is applied to grass seed, then the grass will grow faster.

• The grass in the pot without fertilizer will grow taller and greener compared to the grass in the pot with fertilizer.
