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...

Want to get your students motivated in science class? Given only a piece of aluminum foil, assign groups the task of designing a "barge" that will support the weight of a bunch of pennies.  The group who is able to put the most...

Students participate in a sink or float activity using pumpkins.

Learners 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.

Students create a model boat. In this art lesson, students identify what makes a boat float and use milk cartons to create their own boat.

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...

Students write and explain why an object sinks or floats.  In this buoyancy lesson students demonstrate how items float or sink and graph the results. 

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.

In this plastics worksheet, students experiment with an unknown plastic and determine the polymer name and resin code by using a flow chart of various tests. They answer five questions after they collect their data.

Students will make a lava lamp. For 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.

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...

Archimedes' principle is practiced as chemistry learners practice computing the density of different gases, liquids, and solids. Using a chart of standard densities, they also identify unknown materials by similar calculations. Fifteen...

For this mass worksheet, students fill in a chart with different items and their volume, whether they float or sink, and their density. Students complete this for 10 items and answer 6 multiple choice mass questions.

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...

In this density worksheet, students modify three film canisters in order to make one float in a tank of water, another suspend in the middle of the tank, and the third should sink to the bottom. They collect data on their canisters and...

In this density worksheet, students complete a science lab experiment to determine the density that an object will float or sink in water. Students fill in a chart with their data, answer 4 short answer questions and write 1 conclusion...
