Physical Science Unit: Water Beach Vacation Lesson 2 Changes to Water: Boiling and Freezing:

Students learn water can change state of matter through the addition or removal of heat.
Students will learn the boiling and freezing points of water at standard pressure. Students
will also review how data can be used to create line graphs and these graphs can show
patterns and changes to temperature over time.

"Amazing Race-Elapsed Time":

In this lesson, which focuses specifically on the elapsed time portion of the standard, students work in small groups in a "race" to solve real world problems involving time.

Type: Lesson Plan

Time Out! In this lesson, students will learn about elapsed time. Watching one short video, working with number lines, and working with an online tool will all be ways that the students learn about elapsed time.

Type: Lesson Plan

Hands on the Clock:

This lesson gives students an opportunity to apply time knowledge to identify time intervals to the nearest minute.

Type: Lesson Plan

Do You Have a Minute?:

In this lesson students use an analog clock to tell time to the nearest minute. Addition word problems involving time increments of minutes are solved by students using a number line.

## Model Eliciting Activity (MEA) STEM Lessons

Physical Science Unit: Water Beach Vacation Lesson 15 Beat the Heat MEA Part 2: Cooler Experiment:

In this MEA, students will have the opportunity to apply what they learned about describing
the changes water undergoes when it changes state through heating and cooling. This MEA
is divided into four parts. In part 1, students will develop their hypothesis and receive
information on how to set up the cooler experiment. In part 2, students will use ice to test
the coolers they designed in Beat the Heat Engineering Design Lessons. Students will take
measurements and collect data on their cooler. In part 3, students will analyze the data
they collected. Finally, in part 4 they will develop a procedure for selecting the most
effective cooler to keep water frozen the longest at the beach. In the optional twist,
students will need to take the mass of the cooler into account.

Physical Science Unit: Water Beach Vacation Lesson 16 Beat the Heat MEA Part 3: Analyzing Cooler Data:

In this MEA, students will have the opportunity to apply what they learned about describing
the changes water undergoes when it changes state through heating and cooling. This MEA
is divided into four parts. In part 1, students will develop their hypothesis and receive
information on how to set up the cooler experiment. In part 2, students will be asked to use
ice to test the coolers they designed in Beat the Heat Engineering Design Lessons.
Students will take measurements and collect data on their cooler. In Part 3 of this activity,
students will analyze the data they collected in Part 2 by drawing and interpreting a scaled
bar graph and line graph. Students will participate in a discussion about how to interpret the
data that was collected. Finally, in part 4 they will develop a procedure for selecting the best
cooler to keep water frozen the longest at the beach. In the optional twist, students will
need to take the mass of the cooler into account.
