Frog Game By Leongster
Use Frog Game By Leongster as an ideal projectile-motion game: choose the frog's launch speed and angle so its parabolic path lands on lily pads and eventually reaches the dragonfly.

2. Big Ideas
Key idea The frog game uses ideal projectile motion. The player sets launch speed and angle, then the frog follows a parabolic path with constant horizontal velocity and fixed downward acceleration due to gravity.
What Students Can Learn
- Choose launch speed and angle to control the jump.
- Resolve the launch velocity into horizontal and vertical components.
- Recognise that horizontal velocity stays constant during flight in this model.
- Use lily-pad and dragonfly positions as targets for prediction, calculation, and revision.
Guiding Question
Which launch speed and angle will land the frog on the next lily pad or reach the dragonfly?
3. Try the Investigation
Read the Target Position
Identify the next lily pad or dragonfly position before changing the controls.
Set Speed and Angle
Choose the launch speed and angle, then predict whether the frog will overshoot, undershoot, or land on the target.
Run the Jump
Watch the parabolic path and compare the landing point with the target.
Revise the Launch
Adjust one control at a time, using the previous miss as evidence for the next attempt.
4. Teacher Notes
Lesson Use
Use this as a projectile-motion game where students calculate or estimate a launch before testing it in the simulation. The game context makes range, height, and time of flight visible through whether the frog lands on a lily pad or reaches the dragonfly.
Discussion Prompts
Ask: Did the frog miss because the horizontal range was too short, the vertical motion was too low, or both? What happens to the path when speed changes but angle stays fixed? What happens when angle changes but speed stays fixed?
Teaching Moves
Have students record speed, angle, and landing outcome for two attempts. Then require one sentence separating horizontal motion from vertical motion before the next jump.
5. Concept Check
These questions are generated from the topic and the concept illustrated by the simulation. Use them after students have explored the model.

Expert Challenge
Unlocks after 3 correct concept-check answers on this page.
1. The frog falls short of the next lily pad. Which diagnosis best uses projectile reasoning?
2. Why can students calculate before testing a jump in the game?
3. At the top of the frog's path, what should students say about motion?
4. A student increases launch angle but keeps speed fixed. What should they compare?
5. What evidence shows that a chosen jump worked?
