Sink It

Investigate which items float and which ones sink using this resource.  Learners participate in an activity in which they investigate this phenomena. Then they describe the experimental process, and learn how to display their results.

Students recognize that density determines whether objects sink or float.  In this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their results.

Keep your class afloat with a hands-on density lesson. The challenging lesson has learners experiment with different materials to compare their densities. They learn that increasing or decreasing the amount of the material doesn't change...

Learners conduct a science experiment to determine whether a variety of objects will sink or float. They discuss the concept of density, and then make predictions about whether the objects will sink or float. They then conduct the...

How many yellow Skittles® come in a fun-size package? Use candy color data to construct a bar graph and a pie chart. Pupils analyze bar graphs of real-life data on the Texas and Massachusetts populations. As an assessment at the end of...

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

This Groundhog's Day, challenge scholars to predict, estimate, tally, and graph in a weather-themed instructional activity in which class members play the role of the groundhog to forecast the weather come February second.
