SCIENCE SKILLS REVIEW

​

Some text here about the topic of discussion

​Jose liked to hike, but he was often bothered by mosquito bites.

He read that rubbing lavender flowers on your skin can repel mosquitoes. Jose wanted to find out if lavender flowers work better as a mosquito repellent than store-bought bug spray.

He sprayed bug spray on one of his arms and rubbed lavender flowers on his other arm. Then, he went for a hike. When he got home, he counted the number of new mosquito bites on each arm. Jose repeated this test each afternoon for one week.
