After distinguishing the difference between a fruit and a vegetable and learning what a seeds is, students explore the seeds of various fruits. Students estimate the number of seeds for each fruit (before cutting the fruit open). Then they record the name of the fruit, where the seeds are located, how the seeds get dispersed, 3 properties and they draw what the seed looks like. Afterwards, students compare seed estimations to the average number of seeds each fruit contains. Then students measure (using a ruler) and compare the different sizes of each seed.
Students learn about seed dispersal and are given a letter by Farmer Joe. Farmer Joe has a huge problem: weeds have invaded his garden! He has no idea how they got there. Plants don't move and he did not plant weed seeds! Students write Farmer Joe and explain to him that seeds travel in different ways. (Note: Pokeweed is a poisonous plant. This weed adds more of a challenge for students!)
Students draw the 7 types of seed dispersal that they learned about. Then, they study the images of the weeds (and seeds) that invaded Farmer Joe's garden. Based on the seeds' physical attributes, the students determine what type of seed dispersal caused dandelions, cockleburs and pokeweed to grow in Farmer Joe's garden.
