WHAT IS A HYPOTHESIS?
A hypothesis is a smart scientific guess. We write it with two magic words:
1 IF...
Tell the Action
(What do you change or test?)
2 THEN...
Tell the Result
(What will happen next?)
Model: IF I give a plant sunlight, THEN it will grow taller.
A Match the Action to the Result
Draw a line to connect each pair
Action (IF)
🧊 If I put ice in hot sun,
🏀 If I drop a rubber ball,
🌱 If I never water a plant,
Result (THEN)
then it will bounce up. ⬆️
then it will turn brown and dry. 🍂
then it will melt into water. 💧
B Complete the Hypothesis
Use the word bank words below
Word Bank: push the swing harder it will fly higher it will melt
1. Playground Science Test: How high can a swing go?
IF I
,
THEN

2. Kitchen Science Test: Putting chocolate in the microwave
IF I heat chocolate in a warm microwave,
THEN

Guided Practice
Write Your Own Hypotheses
Rule to remember: IF [Action], THEN [Result]
C Build Hypotheses for Experiments
Read the clue & finish each sentence
🏎️
Experiment 1: Toy Car on a Steep Ramp
Question: Does a steeper ramp make the car roll faster or slower?
Hint: roll faster / roll slower
IF I make the ramp steeper,
THEN the car will

Experiment 2: Salt in Warm Water
Question: What happens when we stir salt in warm water?
Hint: dissolve / stay solid
IF I stir salt into warm water,
THEN the salt will

D My Science Prediction Challenge!
Write and draw your own prediction
👉 Step 1: Circle one science test:
🧲 Put a magnet near a paperclip
🎈 Blow too much air into a balloon
✍️ Step 2: Write your complete hypothesis:
IF
,
THEN
.
🎨 Step 3: Draw what will happen: (Your picture proof)
My Self-Check:
I used IF I told the action I used THEN I told the result
