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.

Second graders explore floating and sinking and make predictions about whether certain objects are likely to sink or float. They read the story Who Sank the Boat? by Pamela Allen. Pupils loacate rhyming words and discuss the events of...

Students examine how weight and balance can effect if an item sinks or floats. They listen to the book "Who Sank the Boat?" by Pamela Allen, and discuss how the smallest animal sank the boat. Students then conduct an experiment in...

Students participate in a sink or float activity using pumpkins.

Students construct clay boats and predict whether the boats will sink or float. Students will hypothesize what caused the boats to sink or float.

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.

First graders drop items into water, and discuss why some things float and others sink.

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

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.

Fourth graders examine pumpkins and use the scientific method to explore its contents.  In this Pumpkin Science lesson, 4th graders measure pumpkins for circumference. Students dress as if they were in a lab and work in pairs to...

First graders discuss why some things sink and some float after dropping a variety of items into water.

Students discover density.  In this density lesson, students discover the properties of objects that allow them to float or sink in water.

Students will make a lava lamp. In this density instructional activity, 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.

Students examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...

First graders examine the water cycle through readings and experiments. In groups, they conduct interviews with others and use the information to create a chart displaying the various uses of water. After brainstorming lists of ways to...

Learners investigate prime and composite numbers. They use a number chart and cross out multiples of 2,3,5 etc. up to 100. Pupils fold pieces of masking tape around pennies and label them with composite numbers, then fold masking tape...

Learners use hands on scientific observation to determine characteristics of wood. They work directly with the materials and record their observations. Students test if wood absorbs water, if wood floats or sinks, and if all wood...

First graders develop skills of scientific inquiry. They determine which objects float and which sink.

Learners examine how density is a value that describes what type of a material an object is made of regardless of its shape or size.

Learners discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...

Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Students work together to create a watershed model. They discover the flow of surface water on different topography. They examine how materials originate from miles away and end up in a different wetland.
