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 activity to assess their current knowledge. There are 30 sentences to complete, and the sentences all deal with present and past tenses.

Note Taking And Skills And Lab Reports
Students perform simple and fun experiments to use the scientific method, take careful notes, and write a lab report. They first make and test a hypothesis about how many drops of water they can fit on the face of a penny and then test...
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
Density
Ninth graders predict when an object will sink or float based on comparison of the density of the object to the density of the substance in which it is placed.
Curated OER
Designing and Floating Boats
Students participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom graph.

Pumpkin Science
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...

Come On Down!
Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

Design a Submarine
Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Changing the Density of an Object - Adding Material
In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

Changing the Density of an Object - Changing Shape
Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

Comparing the Density of an Object to the Density of Water
Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Changing the Density of a Liquid - Adding Salt
Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

Come on Down!
What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

Liquids: Floating and Sinking
Third graders conduct an experiment. In this floating and sinking liquids lesson plan, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.
Curated OER
Floating Soap
Young scholars explore the density of soap. In this science lesson, students conduct an experiment to find which types of soap will float. Young scholars make a hypothesis and record their observations.

Buoyancy Boats
What did the sea say to the boat? Nothing, it just waved. An inquiry-based lesson starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats. Then, they design...
Cornell University
Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Buoyancy: Who Sank the Boat?
Pupils examine whether objects will sink or float. In this buoyancy lesson students bring in objects and experiment to see if they sink or float.
Curated OER
Floating Soap
Pupils use the Scientific Method steps to complete an experiment on various brands of soap to determine their floating capabilities. For this scientific method lesson, students write a hypothesis about the ability of various soap bars to...

Make An Egg Float!
Students analyze density. In this density lesson plan, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.
Curated OER
Stacking Water
Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.
