Challenging Grade 1 Science Worksheets

Science and technology is progressing, and your toddler may be ready to take on more and more challenging stuff than are available in the traditional school system. Here are some worksheets for your child to try.

Worksheet 1 – Plants (difficulty level – challenging)

Group the following plants on the basis of whether they are flowering or non-flowering.

(Tips for teachers: Students in Year 1 are visual and tactile learners. It will be great if you can take them to a botanic garden and help them identify each of these plants before you try this worksheet with them. Please do not insist that students write down these words. At Grade 1, it is sufficient for them to name each plant as flowering or nonflowering. It will be a good idea to encourage students to bring any of these plants to school if they have at home. Still better, you could have a school garden where you could grow some of these plants. Some of the non-flowering indoor plants can be kept inside the classroom too, perhaps on the windowsill)

Worksheet 2 Animals (difficulty level – challenging)

Different groups of animals: mammals, amphibians, birds, fish and reptiles

Group the following animals into the various categories given above

(Tips for teachers: The teacher can define these various categories and draw out the differences between them, but there is no need to insist that students memorize the differences at this stage. Students in Year 1 are visual and tactile learners. It will be great if you can let them see these animals, if not in real life, at least on videos. Please do not insist that they write down the names of these animals. At this stage motor skills may not be developed adequately. If it is possible, it will be a good idea to take students outdoors and see as many of these animals as possible.)
