Changing Planet: Ocean Acidification - the Chemistry is Less than Basic!
A video and laboratory investigation are highlights to this lesson plan on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon...

Carbon Dioxide - Sources and Sinks
Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...
Curated OER
Sink It
Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.
Curated OER
Sink/Float Discovery bottle
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.

Types of Marine Debris
Students conduct an experiment. In this marine debris and environment protection lesson, students categorize trash into piles, predict whether these trash items will sink, float or be picked up and carried by the wind and then test...
Curated OER
Why Do Certain Things Float, While Some Sink?
First graders conduct an experiment. In this density lesson, 1st graders work in groups to test 10 different objects to see which ones sink and float. Students discuss why certain objects float and others do not.
Curated OER
Sink or Swim
Students explore sinking and floating. In this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Students drop various soda cans into water and then discuss why some float and some sink.
Curated OER
I'm Warm Now
Third graders graph how much water is wasted while waiting for it to get warm in the spigot in the sink. In this graphing lesson plan, student first predict how much water is wasted. That night they test it out at home and the next day...
Curated OER
Sink or Float?
Students will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that...
Curated OER
Water Exploration Station
Students explore the characteristics of water. In this water exploration lesson plan, students participate in various learning centers to inquire how water drains and how to increase the flow of water. Students use estimation and...
Curated OER
Density in Relation to Float and Sink
Young scholars explore the concept of density. In this density lesson, students determine the density of various objects. Young scholars use the density of the various objects to predict the density of various unknown solutions.
Curated OER
Which Objects Will Sink or Float?
First graders work in cooperative groups and utilize a variety of materials to test objects ability to sink or float. In this sink or float lesson, 1st graders discover why some object sink and others float. Students will graph results...
Curated OER
The Magical Diving Sub
Learners use their background knowledge of how scientists work to discuss and predict if a given object will sink or float. They record their predictions on a data sheet. Students test the objects and organize them into floating or...
Curated OER
Sink or Float
First graders explore items that sink or float. They cut and glue pictures of objects that they predict will sink or float. Students place thir pictures on a picture of a bucket of water. Students then color the objects that they had...
Curated OER
Will it SINK or Float?
Students predict whether objects will sink or float in water. They classify objects as sinking or floating in water. Students identify and explain similarities between objects that sink and float.
Curated OER
Water: Float and Sink
First graders work in small groups to observe the tendency to float or sink for a variety of objects in water. They sort the objects and discuss their observations. They use aluminum foil to construct a boat and test it for weight capacity.
Curated OER
Sink or Float Water Play Activity
Pupils experiment with different objects to see if they sink or float. They can also choose certain colored items if more review is necessary.
Curated OER
Buoyancy: What will float and what will sink
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.
Curated OER
Weight in Water
Pupils investigate why some materials are able to float while others sink. They carry out a scientific investigation, predict and test their predictions. They record their results in a spreadsheet, and use a forcemeter in another...
Curated OER
Activity # 13 Float or Sink?
Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...
Curated OER
Sink or Float
Students experiment with different objects to test if they sink or float. They predict what the object will do before it is put into the water. They are allowed to play with the items after the experiment is over.
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.
Curated OER
Can You Make A Penny Float?
Learners explore the concept of density by trying to make a penny and other materials float.
