Day Six: Floater What Ifs
Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...
Curated OER
Sink or Float?
Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.
Curated OER
Immiscible Liquids and Density
Students will make a lava lamp. In this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

Design a Plankton
Young scholars explore animal and plant adaptation. In this ecosystems science lesson, students view websites to gain information about plankton and its interdependence within ecosystems. Young scholars identify ways in which...
Curated OER
Density and Buoyancy Lesson Plan
Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Present Time and Past Time
Assess your English language learners and their ability to distinguish between present tense and past tense. Thirty multiple-choice questions are provided here, and learners must choose the correct verb conjugation.
Curated OER
Present Time and Past Time
Review past and present tense, and then give your class this instructional activity to assess their current knowledge. There are 30 sentences to complete, and the sentences all deal with present and past tenses.

To Float or Not to Float - A Lesson on Density
Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.
Curated OER
Does Soap Float?
Students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.

Heavy Ice: Day Five
Students explore physics by conducting a class experiment. For this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five...
Curated OER
Sink or Float
Students construct clay boats and predict whether the boats will sink or float. Students will hypothesize what caused the boats to sink or float.
Discovery Science Center
Kindergarten Observing, Comparing and Contrasting
Although this is a science instructional activity, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common...
