Concepts Covered in the Lesson:. Materials and Equipment:. Mix well. In another bowl, mix: 1 cup of hot water, and 1 T of Borax found in laundry detergent section until it dissolves. Slowly poor Borax mixture into the glue mixture. Knead with hands until liquid is absorbed.
Plastic baggies to store Goop; straws, tooth picks, Popsicle sticks, etc. The class will review liquids and solids. I will ask them what they wrote in their matter journals. I will ask them why they think that what they drew was a solid definite shape or a liquid forms to its container, changes shape easily. I will tell the students that I have a very special treat for them today.
I will show the students the ingredients used to make Goop and ask them to tell me what state of matter that the individual ingredients are in. We will talk about why they are solids or liquids, emphasize the rules for states of matter. Have students point out the reasons on the charts of the states of matter. Borax is a solid because it does not change its shape easily and has a definite shape. Tell the students that they have five minutes for free discovery and observation with the Goop. Suggest that they pull it apart, put it back together, roll it, bounce it, and stretch it as far as they can.
I will encourage the students to share the Goop and to discuss their findings with their group members. I will give the class a signal that will let them know that it is time to put the Goop into their plastic cup and to put their heads down and be silent. I will ask the students to look at what happens to the Goop when it is in the cup. Tell one person in each group to drive their finger straight down into the Goop.
Then have them slowly push their finger into the mixture. Is there a difference? I will bring around straws, toothpicks, Popsicle sticks, newspaper to test if it picks up newsprint.
Let students experiment for a few more minutes. In a whole group again, I will show the students a sample of Goop in a plastic bag and ask them how it looks. They should tell me that it forms to the bag, which is a property of a liquid.
Talk about what the students observed during their exploration. Ask them:. Useful tool: Units Conversion. Particles of matter have size and take up space. At the very least, all matter has three dimensions: length, width and height. This is somewhat obvious when you look at various objects around you.
They all take up space. Note : There are theories that matter may consist of many more than three dimensions. Since we consist of matter, and we are also 3-dimensional objects, we cannot experience or measure other dimensions except through mathematical theories.
Measurements have been made of the diameter of various atoms and the space they take up. It is assumed that the various subatomic particles also have a physical size and take up space. Rust, burn, decompose, ferment. Heat and light are often evidence of a chemical change. Matter anything that takes up space. A liquid has a definite volume, but no definite shape. A gas does not have a volume or a definite shape.
Unit 1 Matter: Properties and Change. Matter and Its Properties The physical material of the universe which we are studying. Anything that occupies space and has mass. Matter and Change.
Basic Vocabulary 1. Matter-Anything that takes up space and has mass. Weight is a measure of the pull of gravity on an object;. What is matter? Matter — anything that takes up space and has mass. Matter — anything that takes up space and has.
Matter Matter, does it matter? Some materials rust iron Other materials do not rust aluminum. Chemical changes are happening in your body right now! During a Chemical Reaction, the atoms are rearranged and a new substance is formed This new substance often has different physical and chemical properties compared to the original substance. Is the amount of matter increased? Is the amount of matter decreased? In other words, the number of atoms does not increase or decrease; they just get rearranged.
The total amount of matter and energy available in the universe is a fixed amount. There is never any more or less. This is called balancing equations. We balance equations because of the Law of Conservation of Matter. Table Salt. Water Formation.
