## K-PS2-1

## Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.

27 Lesson(s)

#### In the previous lesson, students had exposure to conducting a simple investigation. Now the students will take this investigation one step further by comparing the speeds of several vehicles.

Big Idea:

#### Pushing or pulling makes things move, even on the playground!

#### Students will be introduced to the basics of buoyancy in this hands-on, interactive lesson.

#### Many kids have no prior exposure or understanding of science before entering kindergarten. This lesson introduces the concept of science and provides a basic understanding of what the life of a scientist is like.

#### This unit has allowed the students to explore objects in motion. Now it's time to figure out how to make them stop!

Big Idea:

#### Kindergarteners learn that force and motion are all around them!

#### In this unit, students have been exploring speed and force. Now they get the opportunity to conduct an experiment to better understand how forces work.

#### In this unit, students have been exploring the speed of animals. Now, this exploration of speed switches to non-living things as the students compare the speeds of toy cars.

#### Students have been comparing the speed of different toy cars, now they get a chance to see how weight impacts the speed of these vehicles.

#### The students have been exploring all different aspects of movement, including pushes from outside forces. Now they will apply this knowledge in a fun assessment activity.

#### The students have been fun exploring movement and speed. Now it's time for them to have fun applying this knowledge in a friendly race.

#### The story of the Titanic is one that interests and captivates students. This lesson expands students understanding of density as they learn the "why" behind the Titanic sinking.
