Grade 4 Science Worksheet - Challenge Me

NameDate

Circle the answer.

1.
A ramp for a toy wheelchair must be gentle enough to roll up and fit in a 30 cm space. Test: gentle but 45 cm long. What is the best next step?
- cut it to 30 cm and make it steep
- make it steeper but keep 45 cm
- say it works because it is gentle
- add a turn so the ramp fits in 30 cm
2.
Materials: one shoe box, cotton balls, foil. Goal: keep an ice cube for 60 minutes. Which plan stays within the materials?
- put the ice in a freezer bag in a cooler
- cover the box with bubble wrap
- line the box with foil and pack cotton around the ice
- wrap the ice in a wool sock
3.
Which problem statement gives the best criteria and constraints?
- make a cool watering thing for the plants
- water the plants using lots of different stuff
- keep 3 seedlings watered for a week using one 2-liter bottle
- help the class plants somehow this month
4.
A school garden needs a fence that keeps rabbits out and costs under $50. Which is a criterion?
- rabbits cannot get into the garden
- the fence costs under $50
- the fence uses only wood from the shed
- the fence is built in one weekend

About this worksheet

Design and test a solution tasks ask students to define a problem clearly, compare possible solutions, and use evidence to improve a design asks fourth graders to connect observations with an explanation, model, or design decision instead of choosing a fact from memory. Students may choose the most creative-looking design without checking whether it meets the criteria, stays within constraints, or performed best in a fair test. This worksheet uses short investigations and evidence-based situations so students must read what happened, decide which science idea is being tested, and choose the answer that fits the title.

Students identify criteria and constraints, choose fair tests, compare evidence from solution trials, and select improvements based on results. Support versions use familiar objects and direct wording. Standard and challenge versions add closer distractors, fair-test language, and multi-step evidence. Ask your child to point to the measurement, diagram, map, or observation before answering. If the choice does not explain the evidence in the prompt, it is probably a distractor. That habit keeps science reasoning tied to data rather than guesswork.

What your child will learn

Define a design problem with criteria and constraints
Choose fair tests for solutions
Compare evidence from solution trials
Improve a design based on results

NGSS standard: 3-5-ETS1-1

Worked example

If a paper bridge must hold 20 washers using only paper and tape, a folded-beam design that holds 24 washers meets the criterion.

Common mistake

Picking a solution because it sounds clever without checking the test evidence.

Helpful hint

Use the criteria, constraints, and test data before choosing a solution.

Earlier: Renewable and Nonrenewable Resources
