What Happens to Things in Water? 5E Science Learning Cycle Kindergarten
Concept Statement Oklahoma C3 Science Standards Some objects float when placed in water and some objects sink when placed in water. • Process Standard 1.2 Participates in simple experiments to discover information • Process Standard 1.3 Asks questions, make predictions, and communicate observations orally and/or in drawings • Content Standard 1.2 Compares and describes the properties of some objects (float-sink)
Objectives Time • Students will experiment with several different objects and determine whether they float or sink in water. • Engage – 2 min • Explore – 20 min • Explain – 8 min • Elaborate – 15 min • Evaluate – teacher will evaluate
Engage • Introduction • Today, boys and girls you are going to be scientists! We will be testing what happens to several different objects when they are placed in water. * During this time, we will model for students how to use materials appropriately. Rules will also be given during this time, for example: do not put your hands in the water unless it is your turn, do not splash the water, stay in your seat during the lesson. Then, we will let students know which group they are in and at what table. • Scientific Question 1)What do you think happens when objects are placed in water? (I think bigger objects will go to the bottom and smaller objects will stay on top of the water.) *We will give students a handout to answer this question. Students will answer this question before buckets of water are brought to each table. *Everyone at the table can give me a thumbs up to let me know when they are finished.
Recording Sheet • Students can draw and/or write each object below or above the waves according to whether it float or sank (we will give them an example). Aword bank is included for students if they want to write the word above or below the waves.
Explore Materials Safety • 1 recording sheet and writing utensil per student • 1 clear plastic container per group • 2 towels per group (1 placed under the water bucket for spills and 1 for students to dry their hands) • 1 set of objects per group • Crayon • Penny • Rock • Styrofoam cup • Explore – containers of water will be placed on non-slip surfaces to prevent falls in case of spills. • Rule #1 –Do not touch the water or bucket unless it is your turn • Rule #2- Do not splash the water • Rule #3- Stay in your seat
Explore • Procedures • 1) We will group the kindergartners and verbally give them directions before they begin experimenting, and we will also model how to use the materials appropriately. • 2) No more than four students will be placed in each group. (One at a time, each student will test one of the objects in water to see if it floats or sinks.) • We will give each student in the group one object to place in the water right before their turn so they won’t fidget with the materials. • 3) Students will record what happens to each object in words, pictures, or both after each experimentation and before the next person tests a different object. (Teachers will need to stay aware of groups and when they are ready to move on.)
What happens when objects are placed in water? Questions: (*We will ask students in each group the following questions and take notes on what students answer.) Did all of the objects go the bottom of the container that is filled with water? (No, the cup stayed on top of the water.) Why do you think the rock went to the bottom of the container? (Because it is heavy)
Explain Questions: (*We will ask students in each group the following questions and take notes on what students answer.) • 1) Why do you think some objects stay on top of water? (It depends on how heavy an object is.) • 2) What is a form of transportation that uses water? Does it stay on top of the water? (A boat, and yes because it floats.) • 3) What happens when objects are placed in water? (Some objects float and some objects sink.) Claims based on Evidence: (*We will ask students in each group what happens when certain objects are placed in water and how they know that. We will take notes on what students answer.) • 1) A crayon does not float in water. I know this because it sank when I dropped it in the water. • 2) The size of an object does not determine if it will float or sink. The penny is smaller than the cup, but it did not float.
Explain • Concept: Some objects float when placed in water and some objects sink when placed in water. • Scientific terms: • Float-An object floats when it stays on top of water. • Sink-An object sinks when it does not stay on top of water. • Density-The density of an object determines whether or not it floats or sinks when in water. (*This term will only be introduced if students are ready to learn it.)
Elaborate Materials Safety • 1 recording sheet from Explore and writing utensil per student • 1 clear plastic container from Explore per group • 2 towels per group (1 placed under the water bucket for spills and 1 for students to dry their hands) • 1 new set of objects per group • Paper clip • Button • Leaf • Stick • Elaborate - containers of water will be placed on non-slip surfaces to prevent falls in case of spills. • Rule #1 –Do not touch the water or bucket unless it is your turn • Rule #2- Do not splash the water • Rule #3- Stay in your seat
Elaborate • Procedures • 1) We will have students watch on the Smartboard a Sesame Street video about objects that float or sink before they continue experimenting. • http://www.youtube.com/watch?v=dy0S1Pv0eOE • 2) We will have students predict whether they think the following objects will sink or float: paper clip, button, leaf, and stick, and record their answers on a class chart. • 3) We will give the kindergartners verbal instructions again using the new terms that they learned. • 4) Students (in their same groups) will conduct the same experiment a second time, but they will be using different materials. *Kindergarteners love repetition. • One at a time, each student will test one of the objects in water to see if it floats or sinks. • We will give each student in the group one object to place in the water. • 5) Students will record what happens to each object in words, pictures, or both after each experimentation and before the next person tests a different object. (Teachers will need to stay aware of groups and when they are ready to move on.)
What happens when other objects are placed in water? Questions: (*We will ask students in each group the following questions and take notes on what students answer.) 1) Did all of the objects float? (No, the paper clip sunk.) 2) Did it surprise you that the paper clip did not float? Explain. ( Yes, I thought it was going to float because it is not very heavy.)
