Science - Unit D Day 3

Science - Unit C Day 3

SC.5.P.8.1: Compare and contrast the basic properties of solids, liquids, and gases, such as mass, volume, color, texture, and temperature.

Multiple Choice

Students are investigating volume. Volume is the amount of space an object takes up. Each student shares an idea about how to demonstrate that air, a gas, has volume and takes up space. Which idea would BEST demonstrate that gas takes up space?

• Pouring water into a graduated cylinder and recording the volume of the water.

• Making a fan out of a piece of paper and using the fan to blow air onto each person’s face so they can feel the movement of air.

• Laying a wet paper towel on the desk and observe it as the water evaporates.

• Blowing air into a sandwich baggy and locking it shut. The air inside takes up the space inside the baggy.

Multiple Choice

TRUE or FALSE

You should read the volume of a liquid by looking DOWN into a graduated cylinder

• TRUE

• FALSE

Multiple Choice

TRUE or FALSE

Gasses DO take up space

• TRUE

• FALSE

​Mass is the amount of matter in an object. For us in fifth grade, it is okay to say that mass and weight are the same thing. They are actually not, but your eighth grade teacher will help you figure that out. For now, let’s look at this example.

​To find your weight, you would use a scale. Probably it’s a digital scale, and when you step on, the scale will measure your weight. When you are standing still on the scale, your weight and your mass are the same. When you step off the scale and jump up, you are weightless... until you land on the ground. But your mass stayed the same: the amount of matter in your body never changed.

Multiple Choice

Mass is the amount of ___________ in an object

• weight

• mass

• body

• space

​To measure mass, we use a digital scale. In science, we record mass in grams. Outside of science, we usually talk about weight in ounces and pounds. There are several kinds of scales: balance, pan, digital, and spring scales are all kinds of scale we use to find mass. If you have ever been fishing, you have probably used a spring scale. Balance scales can be tricky to use, so for elementary science, digital scales are the easiest and most accurate scale to use.

Multiple Choice

To measure ____________, we use a digital scale.

• volume

• time

• mass

• matter

​VOLUME

Volume is the amount of space an object takes up. Volume is measured in milliliters (ml) and Liters (L). For elementary science, almost all the volume work we do will be finding the volume of a liquid. To find volume, the tools we use are measuring cups and graduated cylinders. Graduated cylinders are more precise than measuring cups. Volume will be recorded in milliliters (ml) or Liters (L).​

Multiple Choice

Volume is the amount of ___________ an object takes up

• space

• weight

• mass

• matter

​TEMPERATURE

​Temperature is the amount of heat in an object. Thermometers are used to measure heat, and temperature is recorded in science in degrees Celsius (°C). Liquid thermometers are the best to measure the temperature of a liquid. Temper scales are both degrees Fahrenheit (°F) and degrees Celsius (°C). Most thermometers you will use have both scales. We often say it is 83° outside: that is in Fahrenheit. You will not have to convert between Fahrenheit and Celsius: both scales will be given. In science, temperature is always recorded on the Celsius scale.

Multiple Choice

In science, temperature is always recorded in _____________.

• Fahrenheit

• Celsius

​TODAY's ACTIVITY

​ Finding the Volume of Solid Objects

Materials measuring cups/graduated cylinders rocks that will fit into the measuring cup.

You could have students collect smaller rock from outside, or use rocks from your rocks and minerals kits.

Procedures: you have to begin with enough water in the measuring cup to cover the rock when it is added, but not go over the maximum measurement.

Example: a 100 ml graduated cylinder. Add 50 ml water. Drop the rock into the water. The water level rises to 75 ml. The volume of the rock is 25 ml. If you had used a 50 ml graduated cylinder, filled it to 30 ml, and dropped the rock in, the water would have gone over the 50 ml total measurement.

1. Students will fill the measuring tool to the volume you pre‐determined. Use a drinking cup at the desk to add water, rather than going to the sink one at a time to measure water. Again, important that students measure the water.

2. Record the starting volume in ml.

3. Drop the rock into the cup. Record the total volume of rock and water.

4. Find the difference between the starting volume and the total volume.

The difference is the volume of the rock. Record in ml.

Multiple Choice

Students are investigating the volume of a liquid. The add liquid to a measuring cup, and record the volume of the liquid. Which of the following shows a correct recording of liquid volume?

• 55° C

• 5 g

• 55 ml

• 55 ° F
