Students will be able to understand and explain the relationship between cause and effect.

Students wil be able to explain how scientists or coders might use cause and effect to solve real-world problems.

Student Notes

1 Hook

Activity: Presenting

Bring in some simple objects to demonstrate cause and effect: pile of books to tip over, balloon to pop, rubberband to shoot, etc.

Ask students what caused the balloon to pop, books to tips over, or rubberband to fly. 

Write down each cause stated on left side of an anchor chart.

After causes are written, explain to students that effects are what happens beCAUSe of the cause.

Ask them what is the effect of each action listed on the anchor chart 

Student Instructions

Students will identify causes. 

Students will identify effects.

2 Direct instruction: Cause and effect and its use in real world problem solving

Activity: Conversing

Ask students to think of a time when they had a problem to solve--a toy that wouldn't operate correctly, a family car that wouldn't work, a shoe that wouldn't lace, a cake that didn't taste right, etc. Ask them to turn and talk with a peer. 

Guiding questions: What was the problem?

What caused the problem?

How did you solve it?


Student Instructions

Students share with a peer a time when they had to solve a problem.


3 Activity--What will Evo do?

Tell students that many jobs involve problem solving and cause and effect. Doctors, mechanics, computer programmers and coders all study cause and effect to solve problems. 

Explain that students are going to observe Evo, their Ozobot, in pairs to identify the cause and effect of certain colors and patterns on Evo's behavior.

Give each pair of students 1 colored copy of a mapped path with many "obstacles" for Evo and 1 paper divided into two halves, labeled CAUSE and EFFECT.


Student Instructions

Students will work in pairs to observe Evo on the colored map and write down the CAUSE AND EFFECT of Evo's behaviors. 


line crosses with another (cause) Evo continues on original path (effect)

line bends or turns sharply (cause) Evo continues on path (or turns and stops--Effect)

4 Debrief

Activity: Conversing

Ask students to share their observations of cause and effect with class. 


Ask students, "Are there any trends or inferences we can make about Evo from our observations? 

What problems did Evo encounter and how can we solve them--change or remove the cause?

sk students how this relates to real-world problem solving? Can they think of situations where this kind of problem solving/observation of cause and effect would be used in the real world? These can be recorded for further investigation at a later time. 

Capture thinking on a chart as "notes" to prove or disprove at a subsequent lesson. 

Student Instructions

Students discuss their experiences and observations of Evo. 




5 Assessment

Activity: Assessing

Observe and record student responses for evidence of understanding that CAUSE precedes EFFECT and that knowing the cause of something can help us to solve problems.
