Standards/ anchors/
competencies PA/Common Core/Standards(Plus any others as may be required) 3.1.2.C4:1. Distinguish between scientific fact and opinion
2. Ask questions about objects, organisms, and events
3. Understand that all scientific investigations involve asking and answering questions and comparing the answer with what is already known
4. Plan and conduct simple investigation and understand that different questions require different kinds of investigations
5. Use simple equipment (tools and technologies) to gather data and understand that this allows scientists to collect more information than relying in only their senses to gather information
6. Use data/evidence to construct explanations and understand that scientists develop explanations based on their evidence and compare them with their current scientific knowledge
7. Communicate procedures and explanations giving priority to evidence and understanding that scientists make their results public, describe their investigations so they can be reproduces, reviewed and ask questions about the work of other scientists 2.3.2.B: Use tools to estimate and measure in standard units.
Formative AND/OR Summative Assessment EvidenceFormal Evaluation
Have an experiment where they must correctly use the steps of the scientific method on their own with little or no teacher directionInformal Evaluation
Asking students questions about the scientific method before, after and during the in-class experiment; did they gain knowledge about the scientific method during this experiment Each student will be given a piece of paper with a mix column and a not mix column. As we go through the experiment, they will have to check off which they think will happen with each of the substances.
This will be collected to make sure the students were participating in the activity
ObjectiveA-B-C-D
Bloom's TaxonomyWebb's Depth of Knowledge (DOK) In groups of two, students will be able to use the steps of the scientific method to complete and experiment 9/10 times. Cognitive Domain Level 3: Strategic Thinking

IntroductionActivating Prior Knowledge
What are the Steps of the Scientific Method?
Do liquids mix with other liquids? Why or why not? What happens when you mix salt and water?
What causes something to float in water?
What are some things that float in water?
Hook/Lead-In/Anticipatory Set
Ask if any one has ever made Kool-Aid. What happens when you put the powder into the water?
Explicit Instructions
Big IdeasEssential QuestionsBig Idea Statement
Matter has observable and measurable physical properties
Some attributes of objects are measurable, e.g., length, mass, capacity and can be quantified Making Predictions
Essential Questions
How can physical properties be used to describe matter? How do we know when it is appropriate to estimate or when it is appropriate to use mental math for and exact number?
Can the students make accurate predictions based on the knowledge that they are being given?
Key Vocabulary
Density: the degree to which something is filled, crowded or occupied Mixing: to combine (substances, elements, things, etc.) Liquid: made up of molecules that move Solid: having three dimensions (length, width, height) Weight: the amount or quantity of heaviness Dissolve: to make a solution of, by mixing with a liquid
Lesson Procedure
Must include adaptations & accommodations for students with special needs
Accommodations, ModificationsPre-Assessment of Students
Can they tell me what happens when you mix two liquids? A solid and a liquid? Observe the physical properties of the salt, water, oil and food coloring
Modeling of the Concept
Talk about making Kool-Aid. The packet dissolves. Sand and water mixed together. Does the sand dissolve?
Before I pass out the materials, I will go over the experiment rules:
1. They cannot eat any of the materials
2. They are allowed to talk with their neighbors, but they must use their inside voices
Transition
Passing out the materials to the students
Have 2-3 student helpers pass out the materials to have the process go quicker
As a way to know that they students have their materials, have them put up the silent llama hand signal, and when every one has done that I will know they will be ready to begin
Guiding the Practice
Can they make a prediction as to what will happen when the food coloring is added to the water?
Can they make a prediction as to what will happen when the water and oil are added together?
Can they make a prediction of what will happen when the salt is added?
Providing the Independent Practice
Have the students add each of the substances to the water; between each have them predict what will happen. The students will fist add the water to the cups
Next, they will add the food coloring to the cup, predicting what will happen when they do.
The students will then add a little bit of oil to the water, again predicting what will happen
Finally, they will add the salt to everything they have combined, making prediction as to what will happen
Adaptations/Accommodations for Students with Special Needs
For a student with disability, the student can work with a partner. Their partner can help them with gather the necessary supplies and the mixing of the ingredients if they do not have the physical capabilities to complete the tasks on their own.
Materials
(reading, technology, equipment, supplies, etc.) Clear drinking glass cup of vegetable oil
Salt
Water
Food coloring
ClosureSummary & Review of the Learning
What happened when we tried to mix the water and food coloring? What happened when we tried to mix the water and oil?
Why did the oil sink when the salt was added? Would this experiment have worked the same way if you used a different substance than salt (i.e. sugar, sand)
Do you think the temperature of the water would make a difference in the outcome of the experiment?
Homework/Assignments
The next time you are helping make dinner and you are adding a solid to a liquid, do they mix, or do they not?
